Launch Google maps app from unity csharp with intent and coordenates

Hello. I can`t find the solution about how to implement the coordenates in the intent to launch google maps (android app) with some coordenates includes.

With this method launch Google Maps app in the android smartphone. But how to add coordenates?? I read about extraData or androidManifest or putExtra but all in Java and I dont know how to implement a solution in csharp to include the coordenates in the intent of this method.

The method (take of this)

 public void abrirGoogleMaps(){
 
         AndroidJavaClass up = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
         AndroidJavaObject ca = up.GetStatic<AndroidJavaObject> ("currentActivity");
         AndroidJavaObject packageManager = ca.Call<AndroidJavaObject> ("getPackageManager");
         AndroidJavaObject launchIntent = null;
 
         try {
             launchIntent = packageManager.Call<AndroidJavaObject> ("getLaunchIntentForPackage", bundleId);
         } catch (System.Exception e) {
             fail = true;
         }
 
 
         if (fail) { //open app in store
             Application.OpenURL ("https://play.google.com/store/apps/details?id=com.google.android.apps.maps");
         } else {//open the app
         ca.Call ("startActivity", launchIntent);
         up.Dispose ();
         ca.Dispose ();
         packageManager.Dispose ();
         launchIntent.Dispose ();
         }
     }
