title: Xamarin.Android: Error android.view.View.mPrivateFlags NullReferenceException
body: <p>I have a xamarin.forms project using Xamarin.Forms 3.2.0.871581 (I know I should update but I am always worried that updates of Xamarin introduces new bugs..).</p>
  <p>And sometimes I have the following unhandled exception which pops and crashes but I do not find any information on the internet and it is very difficult to trace and debug:</p>
  <pre><code>EXCEPTION: Attempt to read from field 'int android.view.View.mPrivateFlags' on a null object reference AT   at Java.Interop.JniEnvironment+InstanceMethods.CallNonvirtualBooleanMethod (Java.Interop.JniObjectReference instance, Java.Interop.JniObjectReference type, Java.Interop.JniMethodInfo method, Java.Interop.JniArgumentValue* args) [0x00089] in &lt;286213b9e14c442ba8d8d94cc9dbec8e&gt;:0

  <p>It seems that there is a problem with the dispatchTouchEvent but I am quit lost on how to debug and solve such error.
  I can provide with the full stacktrace if anyone wants to.</p>
  <p>Has anyone already faced this issue?</p>
  <p>Thanks</p>
