ContentProvider in dynamic module

I have declared ContentProvider in my dynamic module's manifest 。 this would result in ClassNotFoundException.(bad english)
















trace:

Start by inspecting the dynamic module manifest and the ContentProvider declaration for com.exp.initializer.MobileInitializeProvider, then reproduce the install-time delivery scenario from the reported trace. Check whether the provider class is present and loadable in the base APK or delivered module; done means the application starts without this ClassNotFoundException.
