That is strange. I'm using HUR and Wifi Launcher beta versions, and Ic onnect through WiFi direct. It works fine as it connects immediately THE FIRST TIME because when I disconnect, HUR shows "wifip2p: false" and the only thing to make it come back to true is deleting and reinstalling the app. After that it works again the first time, but no more, even though I reboot the tablet / phone. Is there anything I can do?
[Android 4.1+] HeadUnit Reloaded for Android Auto with Wifi
- Thread starter Emil Borconi
- Start date
Hi all,
For me it's not possible to use waze or Google maps with head unit reloaded.
Both apps are showing the map but I can't enter a route or doing anything.
I have to start navigation using my mobile.
Guess some setting is missing. Is there maybe a way to fake standing or handbrake? Rember there was something in the past but I'm unable to find it in settings.
Thx

@Emil Borconi I think I'll give up on AA wireless - it worked before HUR 7 and I tried every possible solution:
1. WiFi P2P also know as WiFi Direct - Strting with HUR 7.1.X and WiFi Launcher 3.8.X ← both devices are connected as shown in Android settings, invite was sent to HUR and accepted, even after 10minutes I'm looking at the HUR main screen and WL shows "looking for car display..."
2. Phone creating hotspot ← both devices are connected, I can update/surf/whatever on my headunit fine. HUR was opened first, WL started manually. Nothing happens, same result as on 1.
3. Car creating hotspot ← Same story, but ofc. no internet on headunit. Still both devices are connected.
As I don't have any in car wifi the 4. solution is a nope. Also HUR shows legacy mode is false.
To me it seems like now the AA server is not detected/sent as some minor versions before the phones screen went at least black for a millisecond.
On some version following this WL showed "not connected to the internet" while I was and now simply nothing happens at all.
I'm still running LineageOS12 (Android 13) on a OnePlus 6 with dual sim, the other device is a PX6-RK3399 M.I.C AV8V6 running Android 10. Wired connection just works, only WiFi not at all anymore.

You'll need to adjust your pixel density in HUR (settings/graphics). I actually adjusted mine to 200 in my SG 8+ in order to get access to the search function.
I found a solution.
I tried the pixel density, as someone also did, and the lower pixel density the more screen real estate. It should be reversed?
For nokia 9 screen resolution landscape mode, the pixel density should be between 248-417 if you want taskbar on the bottom. Up to 247 with taskbar on the side.
Portrait mode is up to 210 for usable keyboard input.
So far I'm going with landscape mode with 417 which will give me the biggest keyboard without obstructing the screen
Thanks mate, setting it to 200 did the trick for my Samsung S22.
I really feared that I have to remove the unit and check the hand brake connector.
Thanks a 100 times
Thanks! I thought there was the beta also for the Wifi launcher app...but there's not.
Seconding this. Just removing this altogether is a regression. It should at least be included as a fourth option in orientation settings.CAN WE BRING BACK THE AUTO ROTATE FEATURE
I run my tablet it landscape and reverse landscape in 2 different cars. Can we just have auto rotate so I do so I don't have to go into the settings every time ?
wondering if anyone can help me. I had HUR paid (got it from the play store) on my android headunit and had an unrelated issue that required me to reflash the rom to fix. After setting the head unit back up, I downloaded HUR from the play store and tried to connect my phone by USB. It would only launch to the HUR menu and will not launch AA.
I then tried the wifi connection and saw a prompt that I needed to install wifi helper so I assume this is a newer version than what I previously had. I did so and was able to connect my phone to HUR wifi and run AA.
I then tried again and it seems I cant run AA from USB. I tested this on 3 android phones that I used previuosly with USB without any issue.
I saw someone mentioned in previous messages of downgrading the version so how would I be able to do that? I believe the earlier version worked fine so I would like to check it.
Thanks.

I get a black screen when i drive backwards and the backup camera was turned on. When the camera video signal stops and i go back to HUR, i still can hear music, but i can't see anything. Closing HUR and starting it again fixes it, but i'd prefer it would not happen. 
I got the AV8V7-Lite from MIC.

I am trying to get hur working between my s22 ultra and Chinese android head unit. I have the app installed on the head unit and accepted all the permission prompts. I have plugged in to usb and then clicked the usb button in the app. My phone shows up on the list. I click my phone name and get dropped back to the main app menu. From there I get nothing! Occasionally the phone might show the android auto logo at the top of its notification bar, but nothing else occurs on the car head unit. I have also tried connecting by WiFi direct and got a confirmation on both phone and app that connection was successful. What am I doing wrong?
It must be the trial app is out of date... I installed the paid on and everything works perfectly
I have a fire 8 hd tablet and it doesn't remember the wifi direct connection. What I have found is after accepting the connection if I close hur and reopen hur it will immediately start working. If I do not do this it just sits there and does nothing.
Hi Guys, I am using Headunit reloaded in a chinese headunit with a Google pixel 7 pro. Everything is working except phone calls. Phone calls does not goes through the car audio. It gives the message bluetooth not connected and phone call works through only the phone speaker. But I have connected the phone to the headunit via bluetooth. Any one has a idea how to fix this?

8BTW, I got AAC audio to work, using FFMPEG, it does increase the APK size considerably but it should be able to work across devices universally. Need to clean up some code, and will be publishing next releases this week.7I've pushed the new version of HUR and WiFi Launcher to beta on playstore (website will follow as well):
and
Also I've updated the description on how to connect over here: https://b3it.freshdesk.com/support/solutions/articles/80001072238-connecting-using-wifi
Some of the big changes:
- AAC is here
- fixed a stupid oooppsy for USB
- went back to standalone activity instead of fragment, that is very old school and basic approach, but many of units have broken or partly broken frameworks resulting in all kind of weirdness, mainly black screen after reverse camera, so hopefully this will do now6
Thanks. Some are full of trojans, and will actually take you to playstore, others do offer the APK, it's a constant fight with them....
BTW, I have (again) made big changes on both HUR and WiFI launcher hope to have them out next week, should hopefully provide a more flexible way to connect automatically or manually over WiFi.
The AAC is a no go, quite a few units are not able to run 2 sessions of MediaCodec in parallel for decoding video and audio separately, so I left it untouched for now with raw PCM being used for audio.
Wanted to rewrite the whole app structure to jetpack compose, however that means to drop support for units running API below 21. Therefore I kept it almost the same as it was now, but reverted back to separate activity for the playback instead of using fragments, this should solve the black screen problem on some units after reveres camera or when putting the app in background and resuming.2
Hi, thanks for the feedback
Actually, if AAC is possible on some devices, you could very well add it behind an audio setting that would be disabled by default. A lot of headunits do not have 5Ghz Wifi, and so, bandwidth isn't enough to guarantee reliable audio. We'd appreciate it a lot if you could add a "Force AAC codec" setting but use PCM by default2
If this issue is not specific to HUR, but it happens on any platform using Waze, then this thread is not the right place. -

Version 7.X Released
- It has braking changes for WiFi, this is mainly due to recent Android SDK limits, like toggling WiFi, BT, getting Mac address and others. Therefore WiFi connection now does need a helper app on the phone.
- Dropped GLES20 as too many issues reported by different bad implementations
- Resolution is now automatically detected based on the cars screen.
- SelfMode (running on phone screen) works without the need of activating developer options in Android Auto.
Last edited: 07/02/2021
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.

- Honda compatibility fixes
- Some other small bug fixes
Version 4.0 Released
How to use the app?
USB Mode
- Plug in the USB to your device (in case of tablet use an OTG cable), when prompted make sure you allow HUR to be the default app for the action and you check the always box.
- 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
Self Mode (when Android Auto and HUR are running on the same device)
- Open HUR and press the self mode button. (you need to make sure Android Auto, Google Play Service, Google maps, Google Text To Speech is also installed on the device and it's up to date)
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
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.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.

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]
19Wifi Mode - Starting with HUR 7.X
Braking changes with version 7.X
Only for phones running Android 9 or higher, if you still use Android 8 phone, you won't be able to connect over WiFi. Device running HUR, can have any version of Android.
Phone Setup:
- Install Wifi Launcher for HUR on the phone ( https://play.google.com/store/apps/details?id=com.borconi.emil.wifilauncherforhur&hl=en_US )
- Make sure you give the app all the permissions, including draw over other apps, otherwise it cannot start Android Auto from the background!
- 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!)
- If you want your phone to create the hotspot, turn on the option to Enable hotspot (this will probably not work if you are on Version in the USA due to carrier limitations!), likewise if you want your car to create the hotspot or you want to use an incar wifi module, leave this option turned off.
- Only turn on the legacy option if HUR specifically instruct you so.
- Connect to the phones hotspot or if you are using an incar WiFi connect to that network. Alternatively if you want HUR to create the hotspot and connect your phone to it, enable the option in HUR settings.
- Open HUR
As soon as the 2 devices are on the same network, HUR will fire up on your car screen.15Hi guys.
Sorry haven't been reading this thread and likely I will have limited time to read it in the future as well, that doesn't mean I'm not supporting the app any further, simply I can't spread myself to so many things.
I've seen a few comments, regarding resolution and some other issues, mainly WiFi Launcher and WiFi connection.
First off, I had taken those functions away because I had no choice, if I want the app to be available in playstore need to compile it with newer SDK, but newer SDK removes abilities to toggle BT for example, or get the devices Mac address, things which are crucial for native wireless Android Auto. Also new changes won't allow WiFi launcher to connect to a specific network, or to disconnect from the network, you can make requests but it's not guaranteed that it will be fulfilled, therefore wiped everything which existed before and started from 0 using Network Discovery Service, which SHOULD be a standard since Android 4.1, but found out it's not and some devices are missing it (hence the flurry of updates after version 7.0 rolled out). The concept is very simple, HUR advertise it's service on the network and WiFi Launcher connects to it, regardless who creates the network, or what WiFi network you are on, as long as it's the same network.
Resolution option, HUR now takes the best matching resolution available and the optimal for the screen. For example, if your screen runs on 1024x600 it will use 1280x720 resolution and add the margins to make the screen output be exactly 1024x600. If your screen is 600x1024 HUR will chose the 720x1280 as now Android Auto does support vertical resolutions as well. In above case selecting any higher resolution makes no sense as the image will still be cropped at 1024x600, and selecting lower resolution will mean HUR needs to upscale. Decoding video at 1080p should be no issue for any device manufactured in the last 10 years, even if it has to do it with CPU and not hardware accelerated. Manually changing resolution does not add any benefit, it creates more customer support, so while some persons might get upset about it, will most probably stick with the decision.
Majority of the problems with connection are coming from all kind of weird implementations and manufacturer broken standards and stuff. I try to make sure the app works for most, but genuinely there is no silver bullet and one size fits it all. In the last few years the number of Android powered units have exploded and they range from super cheap entry level stuff to very expensive sophisticated units, but simply that the unit is powerful in terms of specs, doesn't mean it has proper implementations. Xiaomi, for example still have native Wireless AA broken, even on Android 13, albeit it was supposed to work from Android 11, they have a bug where WiFi disconnects when the GSM/LTE signal is lost. Lenovo doesn't include the Network Service Discovery, many chinese units have broken video driver, where mediacodec gets in corrupted state after a surface is destroyed, and the list of issues can go on forever. So before trashing the app, do consider the above and realize that it's just impossible to make it good for everyone.
Also for support please use [email protected] email address as someone will pick that up, if there is a major incident on this thread please name tag me so I can have a read trough. There will be some more minor updates coming up to address some of the concerns, like no sound in self mode (app should ignore the audio sink setting when running in self mode, but it doesn't so that's an error on me) and other small things.11Hi 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.10
@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.
