I’m using the V4 compat lib to use fragments. I have a Fragment that a top level class with a public, empty constructor, yet still, every once in a while, my app crashes, with this in the stacktrace:
android.support.v4.app.Fragment$InstantiationException: Unable to
instantiate fragment com.myapp.view.flows.fragment.MyFragment: make
sure class name exists, is public, and has an empty constructor that
is public
make sure you call super on the constructor. If you don’t need to make any changes to it you better simply not override it.
