Invalidating caches and restarting doesn't fix the BR import bug...Databinding issue
Almost finished this app and running into compile time error with the data binding aspect in my Movie class I've extended BaseObserver and on trying to build project I can't import BR for the notifyPropertyChanged(BR.voteCount);
on a setter. I can't see the issue but if I try compile and it were to get passed that it crashes on launch with the following stack trace.
I figured if it's a problem with the generated code then how do I tinker with that???
Really puzzled! Any help appreciated.
I've added dependencies can't see no issues there....

Solution
First thing you should do is
Change these lines
implementation 'com.android.support:cardview-v7:29.0.0'
implementation 'com.android.support:recyclerview-v7:29.0.0'
implementation 'com.android.support:design:29.0.0'
to
implementation 'androidx.cardview:cardview:1.0.0'
implementation 'androidx.recyclerview:recyclerview:1.0.0'
implementation 'androidx.design:design:1.0.0'
Problem is with your loadImage method of Movie class. Define it static and it should work.
