在不冻结 UI 的情况下运行后台服务 android

Question

I need to log "Some text" in the devices storage after every 5 minutes can some one point me to the best way to do this. But i do not want the main thread to freeze and the logging thread should be alive all the time. I tried this but it seems to freeze my emulator is there a better way to do the same

public class DataWriteService extends Service {

private FileIOHelper fileHelper= new FileIOHelper("Test.txt");
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}


@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    //Gets location and writes to a file 
    fileHelper.writeToFile(this, "Some text");

    return START_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
}

}

Use Handler or seperate background thread to finish your long work. once you are done,post the value on UI thread.

Btw, on Android O +, the service would only run as long as your app is alive. As soon as your app goes in background, the app will shut down the service. Consider using JobScheduler
