compile failed if use Databinding in project

[JavanZhu]

I used android-hidden-api in my project, but After enable DataBinding, add following code:

dataBinding { enabled true }

            android:onClick="@{mainActivity::clickHelloWorld}"

compiled failed about: Error: com.test.test.databinding not exist. Compile success if I don't use android.jar in android-hidden-api project. any help is welcome!

ps: English is not my mother tongue; please excuse any errors on my part.
