Android BroadCastReceiver for volume key up and down

Question

If a user presses volume key up or down is it possible to detect it in my broadcast receiver? I need the full code.

Here is my Intent filter

Answer 1

The intent does not have an EXTRA_KEY_EVENT extra. It does have an extra android.media.EXTRA_VOLUME_STREAM_VALUE which contains the new volume.

int volume = (Integer)intent.getExtras().get("android.media.EXTRA_VOLUME_STREAM_VALUE");

If you store the old value, you can infer whether volume up or down was pressed.
