Print result:
The complete program is as follows:
Void Merge (JNIEnv * env, jobject thiz) {jclass clazz; // define the domain ID jfieldID struct; jfieldID staticFieldId; // define the domain jstring instanceFieldStr; jstring staticFieldStr; // obtain the class clazz = (* env) through object reference-> GetObjectClass (env, thiz); //
, the last parameter of the two functions represents the method descriptor, and they represent the method signature in Java. (To improve application performance, we can cache the method ID)
instanceMethodID = (*env)->GetMethodID(env, clazz, "instanceMethod", "()Ljava/lang/String;"); staticMethodID = (*env)->GetStaticMethodID(env, clazz, "staticMethod", "()Ljava/lang/String;");
