- If you want an external app use: [Autostart and StaY!][1]

- If you want to do this programmatically you can use a service that polls every "x" milliseconds to see if your app is in the foreground. If it is not, it will start/bring your app in the foreground. Do it like this:
public class PersistService extends Service {
private static final int INTERVAL = 3000; // poll every 3 secs
private static final string YOUR_APP_PACKAGE_NAME = "YOUR_APP_PACKAGE_NAME";
private static boolean stopTask;
private PowerManager.WakeLock mWakeLock;
@Override
public void onCreate() {
super.onCreate();
stopTask = false;
// Optional: Screen Always On Mode!
// Screen will never switch off this way
mWakeLock = null;
if (settings.pmode_scrn_on){
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "a_tag");
mWakeLock.acquire();
}
// Start your (polling) task
TimerTask task = new TimerTask() {
@Override
public void run() {
// If you wish to stop the task/polling
if (stopTask){
this.cancel();
}
// The first in the list of RunningTasks is always the foreground task.
RunningTaskInfo foregroundTaskInfo = activityManager.getRunningTasks(1).get(0);
String foregroundTaskPackageName = foregroundTaskInfo .topActivity.getPackageName();
// Check foreground app: If it is not in the foreground... bring it!
if (!foregroundTaskPackageName.equals(YOUR_APP_PACKAGE_NAME)){
Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage(YOUR_APP_PACKAGE_NAME);
startActivity(LaunchIntent);
}
}
};
Timer timer = new Timer();
timer.scheduleAtFixedRate(task, 0, INTERVAL);
}
@Override
public void onDestroy(){
stopTask = true;
if (mWakeLock != null)
mWakeLock.release();
super.onDestroy();
}
}
The above code has also the "option" to force the Screen to stay always on! Of course you will need the following permissions:
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
and do not also forget to register your service:
<service android:name="YOURPACAKGE.PersistService"
android:enabled="true"/>
