Question

in my app i have to launch another app, only if it is not yet launched.

To launch an app what i do is:

PackageManager pm = getPackageManager();        
Intent intent = pm.getLaunchIntentForPackage("package.of.app.to.launch");
startActivity(intent);

My problem is that if app is already launched, it will bring the app to the front. How can i launch app only if is not present in active and launched apps? thanks!

You can use ActivityManager to get Currently running Applications and to get recent task executed on Device as:

 ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
 List<RunningTaskInfo> recentTasks = activityManager.getRunningTasks(Integer.MAX_VALUE);

    for (int i = 0; i < recentTasks.size(); i++) 
    {
         // Here you can put your logic for executing new task         
    }
