Please Login to Remove!

Hello everyone,
I am trying to create an application targetting 5.0 devices, that will enable the backlight when a sequence of characters are typed on nowhere, but keypad.

Default Re: Background application that listens on keypad.

Only the application that owns the currently focused UI component gets the keystrokes.

There is no global keystroke listener for the Java API's.

Default Re: Background application that listens on keypad.

Ok, it could be convenience key that is manually set by user as a shortcut to my application..
Or event thrown by accelerometer from a background service, which could activate my application..
Let me see this can happen.

Default Re: Background application that listens on keypad.

Accelerator is happening, but you have to shake hard!!. Otherwise I would need my application to be notified (it runs on autostart, so it is already running) when the hot (convenience) key is pressed.

I think of using another (secondary) application that notifies the main (backlight) application (and that secondary application starts on hotkey, notifies and closes), back light is switched on in an event. Then again this hot key is pressed, the main application is notified, to turn it off, and the secondary application closes.

There could be a direct way of doing it. I mean: do I need this secondary application?
