But Here is an example how we can return a jobjectArray which contains lists of data. fill a temp structure to use to populate the java int arrayįor (i = 0 i SetIntArrayRegion(env, result, 0, size, fill) īased on the asked question, this is already explained in the first answer that how can we pass int via jobjectArray. Return NULL /* out of memory error thrown */ However, if you prefer using MediaPipe without Android Studio, please run. MediaPipe recommends setting up Android SDK and NDK via Android Studio (and see below for Android Studio setup). Setup Android NDK version between 18 and 21. Setup Android SDK release 30.0.0 and above.

Since you want to return an int array, then your code is going to look something like this: JNIEXPORT jintArray JNICALL Java_ArrayTest_initIntArray(JNIEnv *env, jclass cls, int size) Install MediaPipe following these instructions. If you wanted to create a single dimensional array of Strings then you'd use the NewObjectArray() function but with a different parameter for the class. If you just wanted to return a single dimensional array of ints, then the NewIntArray() function is what you'd use to create the return value. The following for loop creates the inner arrays which are of type int using the JNI function NewIntArray(). These sample apps use OpenGL, a programming interface for rendering 2D and 3D vector graphics. From the perspective of JNI, that's all a two dimensional array is, an object array containing a number of other inner arrays. To get started using ARCore with Android, you can run either the helloarkotlin or helloarjava sample app included with the ARCore SDK. The outer array is comprised of an 'Object' array creating with the JNI function NewObjectArray(). In this case, the JNI function in the example creates a number of arrays. If you've examined the documentation and still have questions that should be part of your initial question.
