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
READ SECOND POST

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]

- 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

  • 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.

What version of Android is your unit running? I haven't heard of any with less than lollipop being able to run this so far, h.264 decoding is absent or poorly implemented.
Edit....see the bottom of this post

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 Syphe.

The core of the app is the same as the original, and the app does require a hardware H264 decoding supported by the OS. Till now we are not aware of any chinese HU which support this. Please contact me by email and I'll refund your purchase.
You might want to post a "demo" version with just Mike's test mode that plays an H.264 screencap of AAuto running. Would be a good requirement-diagnostic app to have on hand, wouldn't take much time to bake - and it wouldn't have to track source either...

Just be sure to have it display a message popup saying that this is only a requirement check app, not an interactive demo. Something that informs users that its sole purpose is to make sure the decoders work. Maybe call it "Headunit Decoder Requirement Check.apk"

Yeah I thought about that myself.... will probably create a small check app in the near future (just need to catch up with all my other work now, which has been pushed behind to get this done)

bugger, thought it was quite promising when everything started to connect itself :)

I've been building my own app to do simple notification mirroring over a wifi tether, but this would have been much easier haha.

Does anyone know if there is a problem with xda labs on marshmallow or something? I've been trying to download this head unit app for the past week (was trying the old one and now this new one) and every time I click the pay now button for PayPal it just hangs there saying "Contacting PayPal". Is there maybe some other way to purchase the app? Any help would be appreciated, I really want to try this app out!

Hi Emil,

I had a chance to play with your new version. I got it to work, however it was not simple and I have a few issues.

I'm using it in WiFi mode. My Android TV stick(5.1.1) runs HeadUnit app and is connecting to my phone (Samsung Galaxy S7 Edge) that runs WiFi hotspot option.
The problem is that I need to click WiFi (in the menu of HU) many times for it to connect to my phone. It can take 5 to 15 clicks on Wifi option in HU for the phone to connect.
Is it the same for you? Any idea what can be the problem?

Also, I'd like to automate it somehow. I'm not using USB, so I'd like the HU app to be always ready for WiFi connection. Is it possible?

Thank you!

P.S.: I have some other issues/comments as well, but I'll keep them for later :)

Hi Mark.

No it's connecting usually on the first attempt (sometimes on the second) but most of the cases it's first one. Yes I do plan to add a setting for Auto-Start mode in the settings which will make the app start in (Self / Wifi / wifip2p) as selected.

Does your phone have 3g/4g connection while tethering? The change which broke everything im Google Play service 9.2 is actually running a certificate check against google server, so without an internet connection to it won't start.

I had once or twice problem with the wifi myself (I got a debug message saying no route to the ip, meaning the Routing table on the tablet (stick in your case) got something wrong) a simple restarted did cleared the problem.

Please do report back if the problem persist and I'll send you a debug enabled app so I can get an understanding of what is going on, however probably that won't happen before Wednesday, looking forward to a long weekend.... of field work :( that is..

Yes, my phone has 4G connection while tethering.
Lets try the debug output. Could you please send me the .apk with debug messaging? I'm curious to see what is going on when it fails to connect.
Thank you!

Need much more information to help. What S4 firmware, carrier, and Android version are you running? What Nexus 7 firmware? Are you trying to connect over Wi-Fi or USB?
It might be about the Wifi connection, I had some connectivity issues over Wifi myself the last day, but they were fully random, at a first look they point to the TCP socket.... I'm investigating this.

I got some Wifi disconnected myself but it is very random, it can occur after 1-2 minutes or after 3-4 hours... :( so testing potential FIX for the issue isn't going to be easily. At the first investigation it looks to be something related with the pooling/keeping connection alive. I have tweaked this and made a new build, currently running for about 20 mins and looks OK, but as said the disconnect can occur randomly at any point.

The worst part is that the logs do not give any hint on what could be the cause of this, neither on the HU part, neither on the AA side, they only mention a broken PIPE bu no hint on what can be the cause...

I'm guessing you've already tried, but running a 0 byte ping in the background every few seconds to keep the pipe open?
setting socket to keppalive looks to sort the problem, I'm trying to figure out failing handshake at the moment. On TCP sometimes the handshake fails, trying a few more times passes..., handshake over usb always passes....

Looking at the code and notes Mike seems to struggle with it as well in the past...

When trying wifip2p, I can see the wifi connection from the tablet on my phone but when I try to connect to it, it wants a password. How do I know what this is?

Emil Helped me with this problem. You don't actually connect through your wifi networks menu, use Wi-Fi Direct instead. Found here: wifi networks menu > 3-dot menu > Advanced > Wi-Fi Direct
