How can I Detect an favorite android app started?

Question

I want to implement an app which can detect what app launched, to do something with that!

for example I have a list of installed applications in my app and mark one favorite app. and when I start that marked app from default launcher or anyway, I could detect it and do something with that by a background service or broadcast receiver(For example launch a toast message).

How can I do this?

this isnt possible.. to be able to monitor all intents would make android extremely insecure

but there are ways to know when an application is launched. you just have to be creative. this will give you a list of all the applications running.

Code:

ActivityManager am = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> runningAppProcessInfo = am.getRunningAppProcesses();

however to know when an app is launched you would need a timed loop and then check between versions of the List to see if there is a new app. this would suck the juice and be inneficient

AppProtector seem to access the eventlog. maybe you could have a ContentObserver attached to the event log http://developer.android.com/referen.../EventLog.html http://developer.android.com/referen...tObserver.html

EDIT

Interesting. I also found this which solve your problem.

When you open any app from launcher below code will return the info of opened app so now you need to compare a package name with your favourite app package name which you already stored in your app database.

Code:

String str = ((ActivityManager.RunningTaskInfo)this.am.getRunningTasks(1).get(0)).topActivity.getPackageName();
