[ACCEPTED]-JNI , call boolean method-java-native-interface

Accepted answer
Score: 14

My Java signature was to return Boolean instead 1 of boolean.

Also 

jmethodID function2ID = env->GetMethodID(
                    activityClass,
                    "MyFuncName",
                    "(Ljava/lang/String;)B");

needs to be Z instead of B.

jmethodID function2ID = env->GetMethodID(
                    activityClass,
                    "MyFuncName",
                    "(Ljava/lang/String;)Z");
