I met the same issue. On some devices after a while Android kills my service and even startForeground() does not help. And my customer does not like this issue.

I use SharedPreferences to keep the flag whether the service should be running. Also I use AlarmManager to create a kind of watchdog timer. It checks from time to time if the service should be running and restart it.

Creating/dismissing my watchdog timer:

void setServiceWatchdogTimer(boolean set, int timeout)
{
    Intent intent;
    PendingIntent alarmIntent;
    intent = new Intent(); // forms and creates appropriate Intent and pass it to AlarmManager
    intent.setAction(ACTION_WATCHDOG_OF_SERVICE);
    intent.setClass(this, WatchDogServiceReceiver.class);
    alarmIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
    if(set)
        am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + timeout, alarmIntent);
    else
        am.cancel(alarmIntent);
}

Receiving and processing the intent from the watchdog timer:

/** this class processes the intent and
 *  checks whether the service should be running
 */
public static class WatchDogServiceReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {

        if(intent.getAction().equals(ACTION_WATCHDOG_OF_SERVICE))
        {
            // check your flag and 
            // restart your service if it's necessary
        }
    }
}

Indeed I use WakefulBroadcastReceiver instead of BroadcastReceiver. I gave you the code with BroadcastReceiver just to simplify it.
