AndroidJavaProxy

Description

This class can be used to implement any java interface. Any java vm method invocation matching the interface on the proxy object will automatically be passed to the c# implementation.

Note: this API can be used from custom thread, but requires that thread to be attached to JVM first, see AndroidJNI.AttachCurrentThread.

// Opens an android date picker dialog and grabs the result using a callback.

        {
            selectedDate = new DateTime(year, monthOfYear + 1, dayOfMonth);
            // If you have no longer any uses for the object, it must be disposed to prevent a leak
            view.Dispose();
