Eventbus is crashing when my app is running on a device with an API level below 26 and using the AndroidX libraries.

The problem is that a NoClassDefFoundError is being thrown for the TextClassifier that's a parameter in the AppCompatTextView#setTextClassifier() method. The reflection code you use doesn't filter for API level, unfortunately.

A quick fix is to add "androidx." to the system classes in the moveToSuperClass() method. You should probably do this for performance reasons in any case.

The EventBus API will crash if it runs into a method that takes a parameter that the app doesn't recognise. Android gets around this using the @TargetAPI annotation, but this requires a minimum API level of 15.

The easiest way to fix this is reverse the order of checking the number of parameters a method takes and whether the Subscribe annotation is present. This means the getParameterTypes() call is deferred, and if a system library incorporates something not available on a given API level, it won't find an unknown type.
