Android Volume Button Listener when Screen Off

I have an activity listening for volume button events using onKeyDown(), however I am not able to see these events when the screen is off.

Is there any way I can still listen for volume button presses when the screen is off?

Solution

  • No, This is not possible usually because broadcast receiver not work when screen light off because after screen off your volume button get lock and volume level not change.

    Alternative Way to do this:

    But you can achieve using run Media Player with zero sound in background infinite times that keep your volume button active always or you can use Wake Lock to achieve this.

    But I don't suggest to do this method of long time because it totally drain the battery very fast. You can use these alternative method to do this for short period of time otherwise mobile battery get down fastly.
