Detect and get name of an app launched

Question

I've read all the solutions about this topic on stack and I've tried all the solutions, but still I have not found anything about my problem.

Is there any way to detect from a service when an app, I don't know package, is launched?

I need something like:

• my app run in Background
• user launches an app
• my service detects the name of the app
• my service show a toast with the name

Thanks

Hii You can try this in your service which will check every one second for the current app, prior lollipop you will use this code,

final ActivityManager mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
mActivityManager.getRunningTasks(1).get(0).topActivity.getPackageName();
