Hi, I am new to android apps and I am trying to figure out a way to keep an application in foreground running, getting input from the hardware keys only (like volume up and down) but without turning on the screen or unlocking.
I mean lets say you aquire a nice cpu partial wakelock to do your staff, you run an app for chating like a walkie talkie and you want the user to be able to respond to audio messages by pressing the volume up and talking. You can;t have the screen on all the time, it is draining the battery and you can;t have screen lighting or diming on every hard click. You also cant use the camera button if you don;t have one, and the media button is only available when using a handsfree. Still you have to open the screen, disable the keyguard, bring the app to foreground if not already and then receive input from the hard key pressed. So how can I protect the touchscreen or at least turn off the screen but disable the keyguard after the timeout to save battery? I 've seen apps locking the hard keys and not the touchscreen but there is no documentation or availability on turning off the screen light with keyguard locking only the touchscreen leaving the hard keys to the foreground application. Please note that many of the devices do not push buttons so easilly and are on pockets inside cases with holes that allow the user to press buttons but those are not easilly pressed in pocket. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
