ШАГИ, ЧТОБЫ ВОСПРОИЗВОДИТЬ ПРОБЛЕМУ

Добавить ByteBuffer imageBuffer в метод onAvailableListener в SharedCameraActivity: 

@Override
    public void onImageAvailable(ImageReader imageReader) {
        Image image = imageReader.acquireLatestImage();
        imageBuffer = image.getPlanes()[0].getBuffer().asReadOnlyBuffer();
        if (image == null) {
            Log.w(TAG, "onImageAvailable: Skipping null image.");
            return;
        }
        SharedCameraLib.getImageBuffer(imageBuffer);
        imageBuffer.clear();
        image.close();
    }

Попробуйте прочитать JNI 

 extern "C"
JNIEXPORT jboolean JNICALL
Java_com_example_shared_1native_shared_1camera_SharedCameraLib_getImageBuffer(
        JNIEnv *env,
        jclass clazz,
        jobject image_buffer) {
    void* cData = (jbyte *)env->GetDirectBufferAddress(image_buffer);
    LOGI("Image buffer passed successfully.");
}

Редактировать: я начал с создания этой нативной библиотеки и вот что выглядит так: 

#include <jni.h>
#include <android/log.h>
#include <string>

#define LOG_TAG "example_native"


#ifdef __cplusplus
extern "C" {
#endif

void GetJStringContent(JNIEnv *AEnv, jstring AStr, std::string &ARes) {
  if (!AStr) {
    ARes.clear();
    return;
  }

  const char *s = AEnv->GetStringUTFChars(AStr,NULL);
  ARes=s;
  AEnv->ReleaseStringUTFChars(AStr,s);
}

JNIEXPORT void JNICALL
Java_com_java_sharedcamera_1example_SharedCameraLib_getImageBuffer(
    JNIEnv* env, jobject, jobject image_buffer)
{
    unsigned int *data = (unsigned int*)env->GetDirectBufferAddress(image_buffer);

    for (int i=0; i<10; i++) {
    __android_log_print(ANDROID_LOG_INFO, LOG_TAG, "IMAGE BUFFER %d", data[i]);
    }
}

#ifdef __cplusplus
}
#endif

Он также не работал с IntBuffers, что побудило меня начать все сначала. Теперь он передает указатель буфера и не падает.

В чем здесь главное отличие? В первой итерации JNI передавался: 

JNIEnv *env,
        jclass clazz,
        jobject image_buffer

, который, как я предполагаю, связан с тем, почему он не работал? Прошла вторая итерация: 

JNIEnv* env, 
        jobject, 
        jobject image_buffer

Каждый раз, когда я пытался поменять местами jobject и jclass, выдается сообщение об ошибке. Когда вы создаете библиотеку JNI, что определяет, используете ли вы jobject и jclass clazz?

Вы не должны вызывать asReadOnlyBuffer(), потому что это создаст новый, байтовый буфер только для чтения . Новый буфер будет иметь ожидаемое содержимое, но он больше не будет DirectByteBuffer , на что вы и полагаетесь в своем коде jni.
