@gottahavit
Thank you, I resolved, for now, connecting to a different USB port, as you suggested. I didn't check for long time, but seems to work. For all the others: I first used the USB port with 2A charge current capability, disactived. Didn't works well. Now I use another USB port.

@Klamathy
How do you succeed in connecting to bluetooth 2? I tried all the ways, but without success. It didn't ever try to connect to my phone, they don't see each other. Can you help me?
never did anythin special.. activated bt seraching on phone and went to setting bluetooth2 on atoto headunit then add device or something of the sort

It is most likely the Wifi launcher app. I managed to switch to native wireless and didn't have the issue. I didn't think I could get native wireless but managed to find a workaround for it.
I've got the same issue, I agree I think its Wifi Launcher that's failing. I've got a PX6 unit, I may try your Bluetooth workaround and see if it works. Otherwise looks like back to Android 11 for the phone. Unless of course Emil has a Wifi Launcher update in the wind ? ;)


***UPDATE***** Unfortunately can't get this WiFi Launcher issue sorted out. Tried all sort of things and got nowhere. So from my experience confirming it's def a Wifi Launcher issue not HUR.

First huge thx to Emil, been a great help. I'm still trying to get my auto connect working here.

Using a nexus 7 2013, with lineage 17.1 on it. I just flashed a brand new rom so it is fresh now but same issue.

My phone is android one, xiomia

Emil, helped me get set up but connecting BT results in AA saying looking, but no connection. I wanted to eliminate the tablet, it is back to stock for the most part. I installed the HUR and got the redo BT message along with all perms. On the phone I see the show wifi protection box in dev tools but the option never show up in the main menu like they claim to. So I think that is my main issue here but no matter what I do these option do not show up.

I noticed under autolunch that the nexus 7 (tablet) says does not support auto lunch feature. Since I'm running lineage can I fix that?

ALso, was wondering why installing on a second device asks for payment again (same account)?


EDIT: so I was able to go to the HUR app and choose the wifi large button, this let me choose my phone and then I could connect. This is the first time I have seen that work but I thought just a BT connection was enough. Is there an easy way to automate this? I have tasker just no good with it. The Tablet is in a car and comes on when power is applied. Tasker does not sense that well at all, never did. Though I use a wifi signal from my car Dash to trigger events. When the signal is near I'd like everything to start up. Any thouight on the best way to do that?

Hey everyone. Just wanted to note an issue when running the Android 12 Beta 1 on a Pixel 4XL.

Connectivity used to work fine with Android 11 on Beta 6.3

Connection method - Wireless Android Auto - Non-Native

Results after update - Wi-Fi Launcher connects to stereo constantly causing HUR to crash within 20 seconds of establishing a first connection successfully. Constant connection attempts indicated by screen on Pixel 4 doing the double flash to black thing constantly.
I've got the same issue on my Pixel 5 running on Android 12 Beta 1 & 2 as well. Tried to fiddle with some of the workarounds listed in this thread but I'm running HUR on a tablet mounted to my dash, so as far as I can tell there's no way to connect my phone to the tablet via bluetooth as a media device, which seems to be what solves the problem. Has anyone else had any luck with this?

Ok first you need to go into the factory settings on your head unit (the one where you have to enter a passcode).
Tick the option to disable Bluetooth.
Reboot the head unit (this can be done by selecting import profile, then restart).
Once rebooted, go into the android settings menu, select connected devices, then search for "Bluetooth"
You should see "files received via Bluetooth" select that.
Then select Bluetooth and toggle the switch on. You should see the name QCOM-BTD at the top. If you see this then it's working, if not you may need to repeat the process again.
Click pair new device and get your phone ready to pair by going into the Bluetooth settings.
From here you should be able to pair the head unit to the phone. Once paired you should be able to run HUR app and select the native wireless AA for connection. I think a message popped up for me saying native wireless AA is supported and I could see my pixel 4 in the pop up. After selecting that it connected fine.
Which unit is this for? I have a uis7862 fyt, and there's no toggle for bluetooth in factory settings, nor an ability to search in settings. Would definitely be awesome to get native wireless aa support. Right now I'm starting the dev server and connecting that way (hotspot on phone instead of headunit).

So why does HUR route audio thru speaker and not DAC like other apps?

Also is there any way to make the phone app turn on my phones speaker so I can make calls? I do not use a BT head set.

Hey mate, thanks for your insight, seems that I have slightly different settings, I'm using an EONON stereo for a BMW e46. Running Android 8.1 on the stereo itself. I could only find the option to change 1 -> 2 in the factory settings under the Bluetooth category. Not sure this would be appropriate as a solution as it seems you're forcing the bluetooth into a file sharing mode rather than a media device.

Ah thats unfortunate, I'm running the android 10 unit.
Yes you are right it is in file sharing mode, because calls no longer come through the speakers (I just noticed this morning). I got around this by connecting bluetooth to the BMW connection and disabling bluetooth audio. Now calls come through the bmw unit (which uses the roof microphone so it's a lot clearer) and audio is routed over the wireless AA connection.

This is the connection method I used.

I've reverted to using USB connection for now until hopefully an updated version of WiFi Launcher is out. Cannot afford to reset my phone.

Thanks for the amazing experience with the software so far @Emil Borconi :) Amazing to have Android Auto in older cars, you're a genius!

For fyt uis7862 units (maybe others), native aa wireless can work by setting sys.fyt.bluetooth_type=0.


I used my existing config.txt. Modified it and flashed it using the usb method. Didn't initially work, but after an unpair/repair, it's now pretty reliable.

I'm not sure of what functionality was lost by switching from type=1. It does now also pair with my obd elm327 clone as well (Viecar). Haven't tested that it actually works yet though.

HUR stopped working today and I cant get things corrected. Using the standard BT method the AA pops up on the phone and says connecting. The HUR says the info about listing and sending data but then nothing. If I close the HUR on the tablet the AA message goes away, if I bring HUR back up, the AA message returns. So it seem the connection is made but no AA ever comes up.

I also wanted to look in to this HUR wifi launcher. Seem the link to it just goes to a abandon xda site. The Google play store calls it wifi luncher, not wifi luncher for HUR and it does not support my device (pie). Strangely the HUR app says its only for Pi and greater device? Bit confused on that?

Any ideas on either?

Yes, that would work because the bought apps are assigned to the account and not to the device.

and like that its fixed.

Side question, if anyone could. How do you get an app like webviewauto to show up on the app list? I dd try carstream but is not working (but does show up).

    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.

    • 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]

    - New Self mode

    - 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

    • 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
    - Added support for Android 7.0 (Self mode as well)
    - Self mode running in stable and usable way
    - Connecting USB cable will start app automatically (even if phone is running Android 6.0 or 7.0)
    - Supports keyboard shortcuts:
    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)
    - Uses light sensor (if available) for toggling Day/Night theme.


    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.

    Sent from my ELE-L29 using Tapatalk

    @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
