Have you added an intent filter with android.intent.action.MEDIA_BUTTON action?

Have you added an intent filter with android.intent.action.MEDIA_BUTTON action?

If the app is visible then you should be able to catch this event with Activity_KeyPress.

If the app is visible then you should be able to catch this event with Activity_KeyPress.

I know, but it's because I'm using the app as background service.

Actually I solved the problem with an alternative, what I really needed was to save the current volume, and what I have done, is a timer in the service that every X if there is change in the volume of the android saves that variable.

Thank you
