After I set minifyEnabled true, I got this error in my released app

Any idea how to solve it?

In your ProGuard configuration file, you will need to add a -keep rule for the missing method rebase(). The following -keep option will do the trick;

-keep class android.content.res.Resources$Theme {
  void rebase();
}

Using the ProGuard Playground, you can see the effect of your -keep options in the class tree of your project. It can help you create fine-tuned -keep options to solve similar issues.
