java通过jni接口向C++中传值问题

Question

JNI WARNING: instance jfieldID 0x62bb4ff0 not valid for class Ljava/lang/Class; (GetIntField)

in Lcom/xxxx/test/MyActivity;.cmdHUProtoclVersion:(Lcom/xxxx/test/MyActivity$MyVersion;)I (GetIntField)
出现如上的warnning，数值设置不正确，该如何解决？

你这样找类名称是找不到的。要找到类的具体路径，从jni所在的那一层级开始往下目录查找，应该是这样找类，
jclass objresults = env->FindClass("com/XXXX/XXXX/MyActivity/MyVersion");
然后jfieldID my_majorversion = env->GetFieldID(objresults,"majorVersion","I");
