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 optionWill 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.
