Android Expand JNI Local Reference Table

I have a lot of objects to create on c++ and send it to java, I'm using the env->DeleteLocalRef(obj); but I'm getting the following error:

I dont know what means this java.lang.Class... how I can solve this? Increase the reference table? Or what I'm not deleting?

Solution

  • You need to delete local references to classes as well as to objects.
