Exception with Android webview and AndroidJavaClass in Unity

Hi guys,

I'm working on create an Android java webview ( new WebView() ) and I'm getting an exception and I don't have a clue to know what the problem is, my code is.

1.- In the unity project the code is calling the java code with AndroidJavaClass for example:

Debug.Log ("Awake start!");
AndroidJavaClass m_jniUnity = new AndroidJavaClass( "package.name.SingletonClass" );
m_jniUnity.CallStatic ("createWebView", null);

2.- One Android Studio project to create the webview, The code creates the webview with
UnityPlayer.currentActivity as Activity, the current activity is an custom class that extends of
UnityPlayerActivity.

//Activity
public class MyUnityActivity extends UnityPlayerActivity {

//WebView creation
Activity sActivity = UnityPlayer.currentActivity; // Should be a MyUnityActivity
mWebView = new WebView(sActivity); // I checked the activity and it is the expected object

3.- The exception, at the moment when the WebView is created I got this error:

09-01 00:26:28.446 17536-17554/? I/Unity﹕ AndroidJavaException: java.lang.NullPointerException: Attempt to read from field 'android.os.MessageQueue android.os.Looper.mQueue' on a null object reference

Do you have an idea ?
