Getting current running application

Question

How may I get the current running application?

I want to check if the application is running or not in service. I used the following code for that.

       ActivityManager activityManager =
       (ActivityManager)
       this.getSystemService(ACTIVITY_SERVICE );

   PackageManager pm =getPackageManager();
   procInfos = activityManager.getRunningAppProcesses();

But it is returning me list of several applications, even if I pressed back button on their home screen. The running app list is still showing them in the list. But I want that list to show only the apps in foreground.

So, how to differentiate between foreground and background running apps?

Or in other words, how to detect current foreground running applications, or which are not destroyed. I don't want to get background running apps.

You can try this code it gives the package of the currently active screen:

ActivityManager am = (ActivityManager) this
                .getSystemService(ACTIVITY_SERVICE);

// get the info from the currently running task
List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);

ComponentName componentInfo = taskInfo.get(0).topActivity;
if(!componentInfo.getPackageName().equals("your.package.name"))
{
    //Do your stuff
}

You might need the permission

<uses-permission android:name="android.permission.GET_TASKS" />
