Have you used UsesLibraries annotation?
NoClassDefFoundError is mostly thrown when you try to access the class which was available at compile time but it was not available at runtime.

[koder_kids]

yes i added both aar and jar

If so then please show your code.

aar

How do I use .aar in my component?

Note that AAR support for extensions is pretty limited. You can use the classes.jar from within the .aar, but resources in the aar don’t come along with the extension. If the jar file makes use of resources, then the app may crash when it tries to load the unavailable resources.

thank for reply.
what happens if i am using my own app inventor i mean offline version then it work ?
then it works or not ?

@koder_kids

works or not ?

Not, you can't use resources only the classes.

ken i am asking for as component not as extension ?

As a component it should work. The Maps component makes use of this because it relies on osmdroid, which is packaged as an aar. You have to pull out the classes.jar file for building the components package and reference both the jar and aar files in @UsesLibraries. When you build the companion app, it will generate the resource classes similar to how it is done in the standard Android build system.
