Question

Generic collection:

class B {}
class A extends A {}

List<Class<? extends B>> bs = new ArrayList<Class<? extends B>>();
bs.add(A.class);

Works fine (as expected).

But when i try to use androrm(http://androrm.the-pixelpla.net/) library:

class A extends com.orm.androrm.Model {}
List<Class<? extends com.orm.androrm.Model>> models = new ArrayList<Class<? extends com.orm.androrm.Model>>();
models.add(A.class);

I get a runtime error:

E/AndroidRuntime(2177): java.lang.NoClassDefFoundError: com.my.android.A

I can’t understand why?

if you using ADT 17 or above version
