Unable to start activity: NullPointerException

Hey guys,

I'm having some trouble trying to run a custom Android plugin. When I call the Login method (java) from C# and start the activity, it throws an "Unable to start activity: NullPointerException" exception when calling super.onCreate(savedInstanceState).

Here's the Java code:

Code (csharp):

1.  
2. public class GPlusActivity extends UnityPlayerActivity
3. {
4.     private static final String TAG = "GooglePlusActivity";
5.  
6.     static Intent intent = null;
7.      
8.     @Override
9.     protected void onCreate(Bundle savedInstanceState)
10.     {
11.         super.onCreate(savedInstanceState);
12.  
13.         Log.d(TAG, "OnCreate Activity");
14.     }
15.    
16.     public static void Login()
17.     {
18.         Log.d(TAG, "Login");
19.  
20.         if (intent == null)
21.         {
22.             Log.d(TAG, "Creating intent...");
23.            
24.             intent = new Intent().setClass(
25.                     UnityPlayer.currentActivity.getApplicationContext(),
26.                     GPlusActivity.class);
27.         }
28.        
29.         if (intent != null)
30.         {
31.             Log.d(TAG, "Starting intent... " + UnityPlayer.currentActivity);
32.             UnityPlayer.currentActivity.startActivity(intent);
33.         }
34.         else
35.             Log.d(TAG, "Intent is null!");
36.     }
37. }
38.  

And this is the AndroidManifest.xml:

Code (csharp):

1.  
2. <?xml version="1.0" encoding="utf-8"?>
3. <manifest
4.     xmlns:android="http://schemas.android.com/apk/res/android"

Thanks in advance!
