I think it means that JNIEnv.FindClass(Type) needs more error checking. :-)
On a more serious note, what is the stack trace for the NpClassDefFoundError?
My _guess_ is that you're somehow using a non-Java.Lang.Object subclass in a
call to JNIEnv.FindClass(Type), and mandroid only generates Android Callable
Wrappers for Java.Lang.Object subclasses. For example, the following should
result in a NoClassDefFoundError:
IntPtr c = JNIEnv.FindClass(typeof(List<>)); // or some other type
A stack trace would help diagnose this and determine what's calling
JNIEnv.FindClass().
If this is the issue, the fix is to either (1) Don't Do That, or (2) change the
type that's being passed to JNIEnv.FindClass() so that it has Java.Lang.Object
as a base class.
