Use getRunningAppProcesses, which will return a list of RunningAppProcessInfo objects that will give you some data about each running app. One of the pieces of information you can retrieve about the app is its importance, which can have a value IMPORTANCE_FOREGROUND which indicates that the process is the currently active application!

Use this code Its works for me. Dont forgot to use ListView in your Xml File.

ListView listView = (ListView) findViewById(R.id.listview);
        ActivityManager actvityManager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> procInfos = actvityManager.getRunningAppProcesses();
        String[] values = new String[procInfos.size()];
        final String packageName = "my.application.package";
        PackageManager packageManager = getApplicationContext().getPackageManager();
        for (int i = 0; i < procInfos.size(); i++) {
            values[i] = procInfos.get(i).processName;
        }
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, values);
        listView.setAdapter(adapter);

I believe getRecentTasks and getRunningTask were deprecated as of API 21. I'm not sure what you're trying to achieve, perhaps u should try getRunningAppProcess. which give u a similar result.
