Java – JNI, call boolean method

I get a Java method, get a string and return bool

I call it JNI this way:

jmethodID function2ID = env->getmethodID(
                    activityClass,"MyFuncName","(Ljava/lang/String;)B");
        if ( function2ID == null )
            LOG("Could not find MyFuncName Function")

            jboolean IsAutoPlay =    env->CallBooleanMethod(
                    obj,function2ID,env->NewStringUTF(name));

I get a fatal signal 11. What's wrong with any idea in grammar? thank you

Answer: my java signature returns Boolean instead of Boolean

also

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

Need Z instead of B

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

Solution

My java signature returns Boolean instead of Boolean

Jmethodidfunction2id = env - > getmethodid (activityclass, "myfuncname" "(ljava / Lang / string;) B”); Need Z instead of B

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