Now i see these buttons: How can i activate them? 回答1: In order to make the media controls from the taskbar to work, you need to load and configure the SystemMediaTransportControls from the foreground application AND the background task.

This is not working in Android 6.0 with TTS version 3.9.14 (and 3.10.10). So far, I did not see ant post with an answer as to why this is not working in Android 6

问题 n00b here (first Android project). I have been given a custom video codec that has been integrated with an Android firmware build. It's an .so file containing a class that inherits from MediaPlayerInterface, as well as a custom MediaPlayerService implementation to return instances of the custom codec class from the create() factory function for the appropriate file types. I want to use this codec as part of a video player application that can be installed on phones that do not contain the
