Answer 1

The error occurs when trying to create the Service.

You have not implemented onStartCommand(), so the default implementation returns START_STICKY. This means that once your service is started, Android will restart it (if necessary) until the service is stopped.

Your process is getting killed by Android. This can happen pretty much anytime that Android decides it needs the resources. Then, because your service has returned START_STICKY from onStartCommand(), Android will restart your service. Android creates a new instance of your Service class and calls onCreate() on it. In this case, since your ConfigMain hasn't been started yet (since Android killed the process), ConfigMain.sp is null.

Also, don't do this:

    int pid = android.os.Process.myPid();
    android.os.Process.killProcess(pid);

Just let Android kill your process itself when it is ready to.
