Add android view in Unity Activity

Hi, I want to add TextView in the activity which is sent by Unity . I made an android plugin to communicate with unity.

 public void getActivity(final Activity unityActivity) {
 instance = this;
 activity = unityActivity;
 try {
     activity.runOnUiThread(new Runnable() {
         @Override
         public void run() {
             LayoutInflater inflater = activity.getLayoutInflater();
 
             Resources resources = activity.getResources();
             String pkgName = activity.getPackageName();
 
             View view = inflater.inflate(R.layout.android_layout,null);
 
             ViewGroup.LayoutParams param = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
             FrameLayout.LayoutParams.MATCH_PARENT);
 
             // add the view hierarchy in to the unity activity
             activity.addContentView(view, param);
 
             TextView textView = (TextView) activity.findViewById(resources.getIdentifier(String.valueOf(R.id.button_id), "id", pkgName));
             textView.setText("My Text");
         }
     });
 } 
     catch (ActivityNotFoundException e) 
     {
 
     }
 }

And calling in Unity like:

 AndroidJavaObject mClass;
 AndroidJavaObject Innstance;
 AndroidJavaObject activity;
 
 
 private void InitInstance()
 {
     AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
     activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
     print(activity.GetType().ToString());
     mClass = new AndroidJavaObject("com.udacity.horatio.widgetexample.TutorialPointWidget.UnityPlayerPlugin");
     Innstance = mClass.GetStatic<AndroidJavaObject>("instance");
 }
 
 public void TestWithNativeUnityPlayer()
 {
    Innstance.Call("getActivity", activity);
 }

Calling TestWithNativeUnityPlayer() on button press

I have the following error
