Question

I’m new to Android development in Java and Eclipse.

I am trying to develop an app which controls the built in Android media player. It should skip tracks when i press volume up/down. How do I control the media player from code?

Answer 1

use the media button intents:

Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
synchronized (this) {
            i.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_MEDIA_NEXT));
            sendOrderedBroadcast(i, null);

            i.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,     KeyEvent.KEYCODE_MEDIA_NEXT));
            sendOrderedBroadcast(i, null);
 }
