Detect Hardware Volume Button Clicks When Screen Is Off

Question

I've written an Andoid app that uses the hardware Volume buttons for another purpose.

It works fine if the app is running and visible, but when I turn the screen off or let it time out, the button clicks don't get into my handlers.

Does anyone know if there is a way to detect these button clicks when the screen is off?

How were you able to detect the button click when the screen was on? — programmerskillz, Jun 09 '19 at 19:37

The only way to keep detecting things like this when the screen is off is to acquire a WakeLock that will allow the screen to turn off, and still let your app function. However, this drains the battery life quite a bit, and should only be used when absolutely necessary.

In this case, you will need a PARTIAL_WAKE_LOCK.
