You can get the running Application package name using this function:

public String foregroundPackage() {
        ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
        List<ActivityManager.RunningTaskInfo> runningTaskInfo = manager.getRunningTasks(1);
        ComponentName componentInfo = runningTaskInfo.get(0).topActivity;
        packageName = componentInfo.getPackageName();
        return componentInfo.getPackageName();
    }

Thanks, but when i run your code, i get only **com.l.launcher** in any apps. – Mohammadreza Yektamaram Sep 25 '15 at 19:37
i don't know how are you calling the function, but i can assure you it returns the top application package name. – Mateus Brandao Sep 25 '15 at 19:38
I have a loop function each 5 seconds for example, and I putted your code in this loop to get name. only in my app, I get correct name ( **com.example.test** ), but on other application, i get this: **com.l.launcher** :( – Mohammadreza Yektamaram Sep 25 '15 at 19:42
hmmmm, i disabled my **L Launcher**, but know when i open (for example) chrome, i get **com.android.launcher** :( – Mohammadreza Yektamaram Sep 25 '15 at 20:06
