Android Services running in Unity

Hello,

I currently have an Android Bluetooth service that I have made run in the background to constantly receive serial data from my computer or arduino. This Bluetooth connection will be replaced by a sensor later.

So far, the service is working in Android, but I'm not sure how to start a Service within Unity. I have created some Unity Android plugins before, but those methods are only calling static classes.

Heres the java method that I am currently using to create my Bluetooth service:

 public class MainActivity extends Activity {
     private static String TAG = "MainActivity";
     
     
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
 
         startBTService()
     }
     
     
     
     public void startBTService(){
         Intent intent = new Intent(this, bluetoothLibrary.class);
         startService(intent);
     }
 
 }

Now, in the Unity3D side, I'm not sure how to go about calling non-static void functions.

Any help with my problem would be great.

Thanks
