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.

How to use the app?
USB Mode Wifi Mode Incoming connection Mode Self Mode (when Android Auto and HUR are running on the same device) 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? What about intents? 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]
