Android DataBinding Cannot 'cannot find symbol variable' error when i use include Tag

test.xml:

<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <include
        android:id="@+id/include_content"
        layout="@layout/content" />

    </FrameLayout>
 </layout>

content.xml:

<layout  xmlns:android="http://schemas.android.com/apk/res/android">
  <FrameLayout

    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="test button"/>
  </FrameLayout>
</layout>

Java Code:

@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {

    super.onCreate(savedInstanceState, persistentState);
   TestBinding binding=DataBindingUtil.setContentView(this, R.layout.test);       
          Button button = binding.includeContent.button;

}

when i run the application , Android studio build error 'cannot find symbol variable includeContent'

what do i miss?

check this answer.
basically, if you use 1.0-rc3 or below, you need to pass a value to included layout.
if you use 1.0-rc4 or later, it should work without passing a value.
