I want to detect long presses in volume key in a service. Here are my options:

A) Let the user control volume from the lock screen

I wan't to detect if the user has held down the volume button in a service while the screen is off. I already tried (for 2 days) doing it with contentObserver, but the problem is that contentObserver detects volume changes, and volume doesn't change when the screen is off. Is there any way I can let the user control volume from the lock screen?

B) Detect long press for volume button from service

How can I do this? Are there any broadcast receiver's that I can use while the screen is off? Is there a way to implement the dispatchKeyEvent in a service?

I have seen this, but for me the second answer doesn't work in the background. I think the easiest way would be option A because I already have everything set up for when the user changes volume, so can I let the user control volume from lock screen? If not, is there anything else I can do?

Thanks so much,
