[Android] NDK: return IntArray from native code

p_Array is a int pointer contain 256 items.
If we want send it out to Java code, example as below.

jintArray Java_com_example_play_getIntArray( JNIEnv* env, jobject thiz )
{
    jintArray javaArray;         // output type is jintArray
    int size = 256;
    javaArray = (*env)->NewIntArray(env, size);   

    (*env)->SetIntArrayRegion(env, javaArray, 0, size, (jint *)p_Array);
     return javaArray;
}
