Call your Activity using an Intent. It will launch the activity again.

Intent intent = new Intent(MyActivity.this, MyActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //this will always start your activity as a new task
startActivity(intent);

You can also add, android:launchMode="singleTask" inside your Manifest so that only one instance of your activity will be maintained at any time.

Same thing here. :)

To restart your application you can use alarm manager to make your activity open after you exit the app.

AlarmManager alm = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
alm.set(AlarmManager.RTC, System.currentTimeMillis() + 1000, PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0));
android.os.Process.sendSignal(android.os.Process.myPid(), android.os.Process.SIGNAL_KILL);

Intent i = getBaseContext().getPackageManager()
             .getLaunchIntentForPackage( getBaseContext().getPackageName() );
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
