How to simulate hardware media control buttons on an Android emulator

Question

Android supports hardware play / pause buttons on headsets and attached devices. I am trying to find a way to test support for those devices on an emulator. The Android documentation talks about how to add support for hardware playback controls, but, unfortunately, I can't find documentation of how to emulate them. Thanks!

Answer 1

You can send keyevents using adb

   adb shell input keyevent <keycode>

keycode for play - 126, pause - 85 (see KeyEvent)

Bicipital

Note that 85 can also be "Play/Pause". That's the one I use all of the time so I don't have to track whether the media is playing or not. – Woodall

Answer 2

There is another way to do this, from an Android application. You can call AudioManager.dispatchMediaKeyEvent(KeyEvent) and pass in the events with the necessary key code. Don't forget to call it twice, first with the event with ACTION_DOWN, then with ACTION_UP.
