App crashes when closed while using a service android, as im trying to use intents

public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent.getExtras() != null) {
        String temp = intent.getStringExtra("key");
        temp1 = Integer.parseInt(temp);
        counter = temp1;
    }
}

I'm passing data to the service and it works perfectly when the app is open but crashes as soon as i close the app.. I've tried a lot of things and I'm new to android. Any help would be appreciated

Thanks in advance.

Here is the log
