1. How to detect if the application is in foreground, background or not
running?
Why do you need to do this? You get a GCM message, you respond to it.
Whether the app is foreground or background (not running is not an option
- if you're responding to the message, you're running) is irrelevant.
2. How to find out the top activity if the app is running (either
foreground or background)
Again, why do you care?
3. If it is not running, how to launch it.
If you get a GCM message and can handle that message, your app is running.
4. If it is running in background, how to bring it to foreground
Call startActivity, just like normal.
