Question

There is Java class with getLong() and getCharArray() methods and I have jobject link to this class.

This code

jclass clsData = env->GetObjectClass(data);
jmethodID getVal = env->GetMethodID(clsData, "getLong", "()J");
jlong x = env->CallLongMethod(data, getVal);

give me access to long value returned by getLong().

jclass clsData = env->GetObjectClass(data);
jmethodID getVal = env->GetMethodID(clsData, "getCharArray", "()[C");
???

How to get access to character array?

Answer 1

you can get the char array like this way this is simple snippet from another post the complete post here

jobject obj = ... // This is the object you want to call the method on
jcharArray arr = (jcharArray) (*env)->CallObjectMethod(env, obj, getVal);
int count = (*env)->GetArrayLength(env, arr);
jchar* chars = (*env)->GetCharArrayElements(env, arr, 0);
