All over like street lights
Hi guys, i totally gave up. I have no idea how to make it work.
I have factory HU in 2021 Honda Civic, installed HUR paid version on HU and wifi launcher on the OPPO X3 PRO. enable the developer mode in AA and Start head unit server (don't know if it is necessary)
chose the civic BT in wifi launcher, turn on wifi listening in HUR.
then, when i click the wifi in HUR, it shows listening to incoming connection while in wifi launcher showing service is looking for car display, nothing will happen. Or if I turn off the phone BT and on, it will show service is connected to the car display. But HUR still showing listening to incoming connection.
I have read about change hotspot name and password of HU? but there is no such option in my HU.

Can anyone help? Thanks.
The Hotspot name change is done in your phone.

Anyone know how to get HUR to connect wirelessly in reverse? So headunit connect to the phones hotspot?

I keep running into an issue where my phone (a Pixel 6 pro) and another phone (Samsung S21) will connect up and everything runs, then suddenly they'll loose "4G data" and AA will just keep saying its in offline mode/no network connection/etc and everything grinds to a halt.

Super frustrating as im sure all options required in android are ticked to make it fall back to 4G when connected to a wifi network that doesn't provide internet.

I feel if i could get it to work in reverse (start a hotspot on phone, connect HU wifi to it), the whole internet issue would disappear entirely

thanks for the reply. so i should change my phone hotspot name to HUR and password to AndroidAutoConnect? or can i change the name in wifi lanncher to my prefer one?
Scroll back a few pages, i posted how i got mine to work. Basically i seen 2 headunits have an issue dealing out DHCP IP address's to phones when automatically turned on, i have to physically enter the hotspot & tethering menu and toggle the hotspot button and turn off the auto creation option in HUR its self. Then the phone will connect/get an IP on the wifi.

Then just name the Headunit that wifi launcher is looking for the same as the wifi network, same password, and it should work.

seems civic HU doesn't have hotspot function, so i cannot rename the wifi name and password. I also tried to rename the phone's hotspot name and password, still not working. :(

@AusShadoX I think what you are asking is the "old" manual way. Not fully sure what devices you have in the mix but this is how I connect a Pixel6 to a Snapdragon 625 car screen:


1a: Pixel6 - search settings for Android auto, enable developer mode (tap version 6 times etc)
1b: Pixel6 - Android Auto Settings - tap 3dot menu and "Start headunit server"
1c: Activate hotspot on Pixel6 (also, make sure "Extend compatibility" is disabled to force 5ghz"
2: Connect Snapdragon625 screen to phone hotspot
3: Install HUR on Snapdragon625 Screen
4: Allow HUR all location settings
5: Allow HUR microphone access
6: Allow HUR phone access
7: Set HUR desired resolution / dpi
8: Go into HUR Connectivity settings: disable everything
9: Go into HUR GPS - Disable sharing (Snapdragon625 has poor ant)
10: Go into Audio - disable audio sink (I connect my in car bluetooth and the audio is better)
11: Tap Wifi in HUR and Android Auto should start

This works for me and the only annoyance is starting/stopping headunit server

Hello,

I'm having an issue with the app. I'm trying to connect via a USB connection to my Junsun Android Headunit. I got the app installed and the phone loads Android Auto and the Headunit Reloaded will recognize something is plugged in but it will do nothing. I can't get Android Auto to launch on the Head Unit. When I click on the USB settings in the app it sees my phone. But it does noting if I click on it. I'm using the latest version 6.3. Any help would be appreciated. I'm using a Galaxy S10 on Android 11

I had two questions relating to the latest beta release (6.3.1) of Headunit Reloaded

1) How does the native Wireless Android Auto Activate? What button on the main screen do I need to press? My headunit radio and my phone are already connected via android-based bluetooth but I don't see the radio appearing on the Android Auto app when trying to connect to it.

2) "Hey Google" works, but after that it doesn't pick up a single word. I tried changing my voice to my phone and back to my headunit, the setting that was there specifically if "Hey Google" doesnt work, and more but the issue still persists. I am running on Android Auto version 7.1.614524-release.

Witaj,

Mam problem z aplikacją. Próbuję połączyć się przez połączenie USB z radioodtwarzaczem Junsun z systemem Android. Mam zainstalowaną aplikację i telefon ładuje Android Auto, a radioodtwarzacz Reloaded rozpozna, że coś jest podłączone, ale nic nie zrobi. Nie mogę uruchomić Androida Auto w jednostce głównej. Kiedy klikam ustawienia USB w aplikacji, widzi mój telefon. Ale nie zwraca uwagi, jeśli na nią kliknę. Używam najnowszej wersji 6.3. Każda pomoc byłaby mile widziana. Używam Galaxy S10 na Androidzie 11

Też miałem ten sam problem.Pomagało kilkakrotnie rozłączenie i przyłączenie kabla usb. Teraz łączy mi się za pierwszym razem ,ale kiedy włączę opcję transferu plików po usb ,a nie tylko ładowania. Po uaktualnieniu do wersji V6.3RC3 używam teraz łączenia przez wi-fi , działa bezproblemowo.

Translated by GT: I also had the same problem, disconnecting and connecting the usb cable helped several times. Now it connects the first time, but when I turn on the option of USB file transfer, not just charging. After upgrading to V6.3RC3 I am now using wi-fi connection, it works fine.

Hi i got this issue when using the paid version. Seek your advice on this. I'm using 9 inch Android playerView attachment 5482093
From the screen displayed in this photo, click the back button a couple of times on your head unit. In Headunit Reloaded, go to Settings->Display and adjust your screen resolution and/or pixel density. The values that look best for your head unit seem to be specific to each individual model offered by different manufacturers. I use Joying head units in both a Toyota Tacoma and Subaru Forester. My resolution is set to 1080 and pixel density is 280 in the Tacoma. Pixel density is set to 290 in the Forester. You can play around with pixel density a bit to resize the Android Auto UI elements based on your preference. A higher pixel density makes buttons and text appear larger.

Hi All,
I have been using the latest beta V6.3 RC3 on a generic Chinese headunit. Everything worked great until recently. But recently facing a strange issue. While engaging reverse gear while navigation is on, my reverse camera engages fine. But when forward gear is engaged and camera is cut off, the AA screen is behaving in a strange way. Attached here a small clip. Note: I am using SurfaceView as Render Surface.

Hello.

I have the V6.3 RC3 app version
Current phone chargers output at least 2 amps. Some Chinese HU output between 1/2 and 1 amp. Just enough to slow discharge but not really charge. you could try wireless. I've read some people.have had luck using a powered USB hub

    This app is still under development?
    Hasn't been any news on it for a while, really sucks cause it seemed like it was starting to really work, just a few things need nailing down.

    I'm still stuck with a weird issue where if i connect wirelessly, even though my phone knows it can't get internet from the HU, it won't fall back to cellular data, which means you loose most of the functionality of AA :| really wish you could make it work the other way (hotspot the phone, connect HU to phone and link that way, can't get it to work like that either)

    Have to run wired (which works fine, except still get that random disconnect/crash issue when you hit a big bump and the cable jiggles causing it to drop for a second and crash, tried multiple cables but can't get around it....), thinking i might try running an earlier version where it used wifi direct rather than hotspot and see if it'll connect up and what performance is like.

    That should work; start head unit server in Android Auto on the phone, connect head unit to phone's hotspot, select WiFi in HUR.
    Yeah i thought about that, but i have a Pixel 6 Pro and AA is pretty integrated, few extra hoops to jump through just to get to the settings to start the headunit server. If there were a quick shortcut that'd be great (like with wifilauncher i've virtually all automatic, i just can't get the phone to fallback to cell data even know it "knows" it had no internet from the HUR hotspot)

    This work on Android Head Unit? I am interesting to buy one.
    I think its intended for factory units which have wired only Android auto.

    Version 6.3 Beta 1 released
    - Re-wrote whole rendering process to use GLES20, in simple terms video render should use GPU
    - Much better scaling approach
    - Added support for native AA Wireless. This will only work on the units where the BT is accessible from the Android, as many of those android powered Chinese units, have a separate BT board. For devices which supports this, no headunit server or no WiFi Launcher is needed.
    - Changed key mapping, user can now define their own buttons as they wish.

    • If you are running the app on a device with Android 7.0 or higher, you might need to pull down the notification bar and select the connected USB device before the app starts (this is device dependent)
    • If the app does not start automatically when you plug in your phone, you can always open HUR, tap the USB button and select the phone from the list.

    Wifi Mode

    Incoming connection Mode
    READ SECOND POST

    Self Mode (when Android Auto and HUR are running on the same device)
    • Open Android Auto on the phone, go to Settings and tap the Version 10 times to become a developer
    • Once you are a developer from the 3 dotted right corner select Start Headunit Server
    • Close Android Auto
    • Start HUR
    • Select SelfMode

    FAQ / Troubleshoot

    All I get is a black screen

    - If you are using an Android powered headunit (Joying, Xtrons, etc) look for a setting on your device which allows Video Playback during drive
    - Try changing HUR settings and enable Software decoding

    HUR crashes after start
    - Try changing HUR setting and disable "Media Workaround"

    Wifi Autostart doesn't work
    - Option will be removed as it's not deprecated. See intents below on how to achieve this.

    What does the "Share GPS" do?
    - Share GPS actually forwards the GPS data of your device to the phone, so phone will need to do less work, comes really handy if you have an Android powered headunit, with external GPS antenna, however, if you using a tablet which is built into the dashboard, it's possible that you want to turn off this feature, because your phone will have a more accurate GPS fix.

    What is the Sink Audio
    - This option enabled HUR to work as a speaker for your phone. If you disable this option, all the sounds will be outputted on your phone speaker (or if your phone is connected to a Bluetooth device, then they will be played back on that)

    My carrier doesn't provide data allowance for Wifi, what can I do?
    Wifi data used between phone and tablet is classed as intranet not internet so it won't count against your data usage, but do be careful if you have auto-updates enabled on the device running HUR those updates will be downloaded over the phone's Wifi hotspot and that will incur data costs.

    I have audio-sink enabled but phone calls are coming from the phone speaker. Why?
    Android Auto is designed to sink all the audio over USB (Wifi) except phone calls where it will ALWAYS use a Bluetooth headset, if none is connected it will just flip the phone to speaker mode.

    Are any hardware keys supported?
    • Volume Up
    • Volume Down
    • Media Next
    • Media Prev
    • Media Play
    • Media Stop
    • Media Rewind
    • Phone answer key (In case of incoming call it will answer the call, in case of not being on a call it will take you to the dial pad
    • F key - Same as Phone Key
    • M Key - Mic
    • H Key - Takes you to home screen

    What about intents?
    • gb.xxy.hr.WIFI_START Can be used to start HUR and try to connect using Wifi.
    • gb.xxy.hr.playpause Same as pressing the Play/Pause media button.
    • gb.xxy.hr.next Same as pressing the Next media button.
    • gb.xxy.hr.prev Same as pressing the Prev media button.
    • gb.xxy.hr.mic Triggers microphone input.
    • gb.xxy.hr.phone Same as pressing the dial key (answer phone call when ringing, takes you to dialer screen otherwise).
    • gb.xxy.hr.day Enables day theme.
    • gb.xxy.hr.night Enables night theme.
    • gb.xxy.hr.togglenight Switches between day and night theme.



    I need more help.
    - Feel free to ask a question on this thread, or you can always drop me an email to [email protected]

    How do I collect a bug report / logcat

    1. Enabling Developer Mode

    • 1. Open Settings > About phone.
    • 2. Scroll down to the Build number.
    • 3. Tap the Build number 7 times in quick succession until "You're now a developer" appears.
    • 4. Return to the Settings menu and select Developer options.
    • 5. At the top of the screen, make sure 'Developer options' is set to On (green).
    • 6. Scroll down to Debugging and enable both USB debugging and Bug Report Shortcut on (green).
    • 7. Tab on Logger buffer sizes: Default setting is 256K. Select 16M to help capture more information for debugging. Of note, it can affect the apps performance especially with lower spec phone, so change it back after you have finished submitting bug reports.


    2. Capturing a Bug Report
    It's very important to do this right after you experience the issue again, so your device can log at least one occurrence of the issue.
    • 1. Hold the Power button down until the menu appears.
    • 2. Select Take bug report. and wait for the device to capture the bug report.
    • 3. Tap the 'Bug report captured' notification when it appears.
    • 4. Share the bug report. (I recommend to email it to yourself.)
    • 5. Download the bug report to your computer.
    • 6. Send the bug report by email to [email protected]


    Setup demo


    IF YOU UPGRADED TO ANDROID AUTO 2.X

    Version 2.2 Released - With some major changes
    - Fixes for Communication Error 2 received with Play Service 10.X
    - New Self mode
    - Corrected channels order
    - Unlimited browsing working when car is parked (only for Android Auto 1.6)
    - Totally changed the Day/Night toggle logic, now the calculations are done inside the headunit app and updated each 10 minutes, so if you're driving all day the sunset/sunrise should be correct. even if you are 500 miles more to the north or west or whatever.
    - Added Auto adjust volume option (works for bluetooth audio as well).
    - Changed all the key mapping, and using real keys instead of simulated touches:

    Supported hardware keys:
    1. Volume Up
    2. Volume Down
    3. Media Next
    4. Media Prev
    5. Media Play
    6. Media Stop
    7. Media Rewind
    8. Phone answer key (In case of incoming call it will answer the call, in case of not being on a call it will take you to the dial pad

    10. D key - Changes to Day theme
    11. N Key - Changes to Night theme
    12. M Key - Mic
    13. H Key - Takes you to home screen

    The following keys are still usable but they are based on simulated touches:
    • Up Arrow = Scroll Up
    • Down Arrow = Scroll Down
    • Left Arrow = Moves to next Left tab
    • Right Arrow - Moves to next right tab



    Version 2.0 Released
    Changelog:
    - Fixed calculated night mode
    - Added support for Software decoding (should work now with any device) - If you have problems running HUR, go to settings and enable Software decoding. Do not use software decoding with audio transport, the audio playback will suffer a lot, consider streaming the audio from the phone to a A2DP directly or using a cable to connect the phone Jack to the stereo AUX, or if your phone is rooted you might want to consider Wifi Audio streaming app, it's too much to ask from the Software decoder to do both Audio and Video, unless you have a very strong CPU, but if that is the case I'm pretty confident that the Hardware decoding will work on the device.
    - Added option for letterbox display (prevent distortion of stretch)
    - Added option to start the app when connected to Wifi

    Software Decoding
    - Based on the feedback although it works, I'm not recommending this app for those with Joying or any other Rockchip (RK3188, RK3066) powered headunit. Feel free to use the trial and decide yourself, but it appears to be painfully slow on those devices.


    Version 1.5 Released - Key features
    - Stable Wifi connection

    If you are updating from version older than 1.2 please read:
    You won't be able to install it over the old one (Key signature changed!), so please uninstall the previous version before updating, HOWEVER if you were upgraded for free from Mike's version, please follow this steps:
    1) On XDA Labs, click the download Stable
    2) When prompted to install select Cancel
    3) Open a file explorer and go to Storage -> Android -> com.xda.labs -> files
    4) Locate the newly download APK and copy it somewhere else.
    5) Uninstall the old version
    6) Install the APK which you just copied.
    If you miss any of the steps, just reinstall the old version you received from me by email and try again, let me know if you are stuck.

    App requirements:
    - Android 4.1 or higher
    - H264 Hardware decoding!

    How to use the app: (Please read this steps before asking for help)
    1) USB OTG
    - Plug in the OTG cable to your tablet, connect your phone, done!

    2) Self mode (for AA 2.0) - See Video
    - Start Android Auto, Go to About, if you are not a developer yet press the "Android Auto" header 10 times, from the 3 dotted menu select "Start Head Unit Serve"
    - Exit Android Auto
    - Start HUR and select Self

    3) Wifi
    - From the phone create a Wifi hotspot
    - Start Android Auto, Go to About, if you are not a developer yet press the "Android Auto" header 10 times, from the 3 dotted menu select "Start Head Unit Serve"
    - Connect your tablet to the newly created Wifi hotspot
    - Start the Headunit Reloaded app
    - HTC ATTENTION! If your phone is a HTC, please change the default IP address to: 192.168.1.1
    - Select Wifi

    4) Wifi Direct (not supported by all phones/tables)
    - Start Headunit Reloaded on the tablet
    - Select Wifi Direct
    - On the phone go to Settings -> Wifi -> Advanced -> Wifi Direct, join the group. (Do not try to connect as to a normal Wifi it will not work!)
    - On the phone start Android Auto, Go to About, if you are not a developer yet press the "Android Auto" header 10 times, from the 3 dotted menu select "Start Head Unit Serve"

    Other important notes:
    Software Decoding
    - Based on the feedback although it works, I'm not recommending this app for those with Joying or any other Rockchip (RK3188, RK3066) powered headunit. Feel free to use the trial and decide yourself, but it appears to be painfully slow on those devices.

    To exit the app
    If you are connected with USB, just unplug the USB cable, DO NOT use the exit from the menu. If you are running Wifi, Wifi Direct or Self mode, ALWAYS use the exit button from the left drawer menu!

    Audio transport option
    Will forward (sink) all the audio from the phone to the tablet if enabled, EXCEPT phone call audio, that will go trough the phone speakers or Bluetooth Handsfree if connected. If you wish to stream all the audio from the phone directly to your A2DP bluetooth, then simply disable the Transport Audio option.

    Day/Night toggle
    The device running the Headunit Reloaded app will be responsible for changing the theme. You can chose between using the light sensor of the device to toggle between day and night mode, or you can use calculated sunset sunrise mode, or even force it to one theme only. If you have previously installed AA Helper to your phone, please uninstall it!

    Auto Start on Wifi
    This option will launch HUR whenever you are connected to a Wifi (specific Wifi can be named)

    Auto increase volume on speed
    The logic behind is a very simple approach, every time the speed increases it will send a vol + key to the phone and every time the speed decrease it will send a vol - to the phone. This requires the device running HUR to have a GPS receiver.



    OLD STUFF:

    Version 1.3 (Wishlist version) - Released
    - Added option for easy car mode toggling. (Car mode can be disabled if not using Self mode - avoid conflict with other Car apps)
    - Auto Hide status + action bar while running the app no need to use the Hide option from menu
    - App will automatically close when Wifi connection is lost


    Version 1.2b - Released
    - Buffer overflow protection - Special Thanks to invis-zz from GitHub (https://github.com/invisi-zz) - This should random crashes while using the app.
    - Removed Send Log feature (it was classed as backdoor/trojan and Google was blocking the app on playstore)
    - Updated OpenSSL library to 1.0.1t (used OpenSSL contained vulnerabilities and Play store blocked the app)
    - Managed to get the app on PlayStore (wonder if it will stay...) - https://play.google.com/store/apps/details?id=gb.xxy.hr
    Signature Key changed!!!!
    I had to update the APK signature key (I'm trying my luck with Play Store), this means if you try to install the new version you won't be able to install it over the old one, so please uninstall the previous version before updating, HOWEVER if you were upgraded for free from Mike's version, please follow this steps:
    1) On XDA Labs, click the download Stable
    2) When prompted to install select Cancel
    3) Open a file explorer and go to Storage -> Android -> com.xda.labs -> files
    4) Locate the newly download APK and copy it somewhere else.
    5) Uninstall the old version
    6) Install the APK which you just copied.
    If you miss any of the steps, just reinstall the old version you received from me by email and try again, let me know if you are stuck.



    Version 1.1 Stable - Released
    Jumping the version number due to significant amount of changes:

    • Removed Day/Night/Auto mode (see bottom of this post for a better solution.)
    • Added new setting for 720p Video - Fully working now (even on Wifi)
    • Changed Self mode start sequence (if the phone is rooted it will start automatically and then go back to HU), if your device is not rooted, please use the following sequence to start Self mode:

      1. Start HU app
      2. Select Self mode
      3. When AA opens select Start Developer Server
    • Added support for hardware keys (simulating touches), so if your tablet is integrated with the car remote you can control AA from the remote.
      Hardware keys as follow:
      1. M = Start the Mic
      2. N = Navigation Tab
      3. P = Phone Tab
      4. H = Home Tab
      5. E = Entertainment Tab
      6. UP Arrow = Scroll Up
      7. Down Arrow = Scroll Down
      8. Left Arrow = Moves to next Left tab
      9. Right Arrow - Moves to next right tab
      10. S = Play/Pause button (only works in Entertainment tab)
      11. F = Next track (only works in Entertainment tab)
      12. R = Prev Track (only works in Entertainment tab)
    • Some other minor tweaks, to improve stability and make Self mode connect 9 out of 10 times.
    • Fully integrated x86 native binaries
    • Declared app as CAR HOME, for those using SelfMode it is crucial, that when you get prompted which should be the default CAR HOME app (Android Auto or HU) you select HU!!! - This is needed to be able to bring back the HU on top after a successful connection is established. AA is trying to override everything..... and to block the user out of his phone as soon as it's connected to the car.
    • Transport Audio option will affect USB connections as well (You can keep the audio on your phone/bluetooth, when connected with the OTG cable)



    Version 1.03b released - Beta

    - You will find it in XDA Labs (under the Beta version)
    - Fixes Wifi/Self mode for some devices which didn't connect before
    - Increased stream buffer size to match the DesktopHeadUnit app (128Kb vs 64Kb)


    Version 1.02 release
    - Fixed wifi not connecting on some device only after numerous attempts (see explanation below if interested)

    The issue looks to be related to the timing, on some occasions and on some devices the phone either sends the SSL data too soon, either too late, either to slow :) and because the TCP socket is set to non-blocking mode, it can end up in a missed packet in the initial Handshake. I have tweaked this now, so the TCP socket will connect in non-blocking mode, but will switch to blocking mode and wait for full message after a successful connection and once the SSL Handshake is out of the way it will revert back to non-blocking mode, uhhh event reading this makes me dizzy :)
    This however could make the initial startup slightly slower than it was.

    - Corrected AutoStart option (Working properly now)
    - Fixed USB device overlapping Settings text on the drawer menu
    - Added "Send Log" function to be used if there are problems for easier debugging.


    Version 1.01 released

    - Potential Wifi disconnect fix (see: http://forum.xda-developers.com/showpost.php?p=68078605&postcount=16 for details)
    - AutoStart option added to the menu


    Very sadly Mike passed away this year and his software stopped working after a Google Update, he left us a slightly outdated GPLv3 version of the software at: https://github.com/mikereidis/headunit which I have used to rebuild (or ty to) rebuild up to his latest build with some additional small modifications as well as fixing the issue caused by Google.

    The forked version can be found on: https://github.com/borconi/headunit if anybody is intersted.

    Since the app released by him isn't working any longer I have created the new version of it and slightly re-name it just to avoid any confusion.

    I take almost no credit in this app, except for some minor changes, and finding the fix for what Google have broke (changed), which was a painful task.

    I'm not a developer as such, and this app would never have existed if it wasn't for @mikereidis, however I have spent now several weeks studying the app and understanding how it's working and I plan to continue with the maintenance/development of the app.


    I have published the app on XDA Labs under the new name: "Headunit Reloaded Android Auto" and it is now available for purchase. As I have stated previously I'm intending to support all of Mike's customers, so if you have purchased Mike's application before, please email me a proof of purchase to [email protected] and you can have a free copy of the spin-off app.

    How to use (Self / Wifi ) ?
    1) Self mode.
    See instructions in version 1.1

    2) Wifi Mode
    Start AA on your phone, tap the header 20 times till you become a developer, once that is completed from the menu select Start Head Unit server. Now start tethering on the phone, connect the tablet to the newly created wifi hotspot, start HU on your tablet and select Wifi. This will make the HU app try to connect to the default Android gateway (192.168.43.1), if you need to change this, use the Settings menu from the HU option list. If HU doesn't start on first, do try a few more times, first setup sometimes proves tricky. If this is the first time you connect your phone to the a HU, please make sure you answer all the questions on the phone.

    3) Wifi p2p
    This is not supported by all devices and might not work for your device, plus sometimes it can be slightly buggy. Start WifiP2p on the tablet from the HU. On the phone go to Wifi Direct (this is usually found in Advanced Wifi settings settings - DON'T TRY TO CONNECT LIKE TO A NORMAL WIFI and look for a new available connection. If you can see one tap to join. Once you joined the network, give it about 30 seconds or so, then open the AA on the phone and start the head unit developer server (same as describe it above). If you're lucky it will work instantly, if not you might need to play around with it.


    Other Options:
    Possibility to toggle the Audio mirroring when using a Wifi connection. By disabling the Audio mirroring, you will keep all the audio on your phone rather than on the tablet (or on the handsfree) if the phone is connected to the handsfree. This will improve the performance greatly, since audio will use up a significant quantity of Wifi bandwidth when communicating between the 2 device.


    USB OTG connection.
    Have remained unchanged and it will work same way it did till now, see original threader for details.

    I will monitor both Threads and will do my best to help and support everybody.

    Wifi Mode Setup - Starting with HUR 5.2

    Method 1 (prefered)
    Only available if phone runs Android 9 or higher
    Phone Setup:
    1. Install Wifi Launcher for HUR on the phone ( https://labs.xda-developers.com/store/app/com.borconi.emil.wifilauncherforhur thanks to @gvillo89 for rewriting the app)
    2. Open the app and select the car's BT adaptor from the list (make sure phone is NOT connected to the car's BT, but BT is enabled!)
    3. For Android 10 and above make sure you set location permissions to ALWAYS, otherwise it won't work
    Car/Headunit setup:
    1. Enable Listening mode in HUR -> Settings -> Connectivity
    2. Restart HUR
    3. If phone is already connected to the car's BT disconnect and reconnect
    Using the WiFi&BT button
    - This won't work on all units. It needs to know the phones BT address (you can set it up in HUR -> Settings -> Connectivity).
    - Phone setup is identical as above, but it becomes mandatory to give WiFi Launcher access to notifications!
    - When you press the button on the car screen it will turn on the hotspot and send a message over BT to the WiFi Launcher app which will try to initiate the connection

    Potential problems & solutions:
    • HUR can't turn on WiFi:
      - you can try to use other ways to turn on the hotspot, for example manually or using tools with root access
    • HUR can't automatically configure the hotspot:
      -This will happen if the unit running is based on Android 8 and above. Make sure you manually set the hotspot name to: HUR and the password to: AndroidAutoConnect
    • Phone connects but has no internet access:
      - Each phone is different, but usually there is some setting under the phones WiFi settings which suggest to allow mobile data while connects to WiFi. In some cases you have to forget the HUR network on the phone, then when you re-connect to it make sure you don't tap the notification which says the WiFi has no network. Hard to give exact advice because of so many different implementation on phone side.


    Method 2
    Available on all phones including those running Oreo and below

    Phone:
    1. Open Android Auto
    2. go to settings, scroll down and tap the "version" 10 times you will become a developer
    3. Now from the 3 dotted top corner menu select, "Start headunit server"
    4. Exit Android Auto
    5. Create a Wifi hotspot
    Car/Headunit:
    1. Connect to the phone's hotspot
    2. Open HUR (Headunit Reloaded)
    3. Press the Wifi button.

    Automation
    To automate starting of HUR when connected to a Wifi network you can use your preferred automation app, for example macrodoid or tasker or anything else, using intents. The intent needs to be configured like this:
    - Action: "gb.xxy.hr.WIFI_START"
    - Packaged: gb.xxy.hr
    - Type: Broadcast
    - Receiver Class: gb.xxy.hr.WifiReceiver
    See below example screenshots for macrodroid and tasker.

    Hi guys.
    As you probably know I'm pretty busy with a major project which means way less time for XDA. Sadly as we know XDA Labs went down for a while, and there are many of you who have purchased the app on XDA Labs and not able to access it any longer.

    For all those, you can now used the following link: https://www.b3itlabs.com/download.php you will need to fill in the paypal email address you used to make the purchase, the page will then generate a one time unique link which will be emailed to you.

    Link will allow you to download to pick and download the APK.

    As I've said all links are one time use only, so you won't be able to share those links, if you need to re-download the app, you will need to request a new link.

    I will be adding checkout option to the website as well hopefully in the near future so new users can get a copy of the apps if needed.

    If you need any support, please contact me directly by email.

    P.S. I'm working on a new version, of HUR, still need to fix some bugs, but should be a pretty big step forward compared to previous version.

    Isn't that exactly what you just joined up to do?
    You didn't join to ask a question. You could have started with telling us what device and Android version you are trying to connect with/to, and perhaps someone could help you constructively.

    @googlebox:

    Normally I try to take criticism in a positive and constructive way and I try to improve my service I'm providing.
    Also when you bought the app you did bought support with it as well, indeed the app help button brings you to this thread as 99% of the issues/problems/solutions have been discussed in here, but in case you are still lost or not sure, you can at any given time shoot me an email and normally I reply in max 24 hours. If there is one thing I pride myself with is that I really do my best and try to go the extra mile to give support to all users, which is sometimes an extensive and exhausting thing to do, and this will be reflected in the reviews as well.

    Now to echo the above quote, without actually saying what is the problem, where are you stuck, what have you done, it's really hard to give you any guidance.
    Judging from your comment, I'm guessing that you try to connect the 2 devices over WiFi but maybe I'm wrong and you try to connect them over a USB cable, while I don't like to be arrogant, I will make an exception this time. The LAYMAN, will understand to have Android Auto wireless in a car it will cost him $500+ if he/she goes to buy a Kenwood/Pioneer receiver and then pay another $100+ for fitting. The layman won't try to cut the corner and have some tablet fitted into the dashboard trying to mirror the screen, that is not a layman any more. So if you do consider yourself a layman, please feel free to go and pick up a unit which can offer you the desired solution, I will refund you the app price no problem so you can spend it on that solution.

    I have never ever refused a refund from anyone even if they used the app, if they weren't happy with it, I even send copies away for free, when some users contacted me that they can't afford it, I've spent sometimes hours with users on different issues and support, in some rear cases I drove down to personally help out the users so your comment, really made it personal and I think this is the very first time I took a comment personal. So to answer you in a question, RTFM if you can't manage tough luck shoot me an email and I'll refund you.
    Once again I do apologise for the harsh language.

    Next beta will have a bonus surprise.... one more service is now decoded... :D
