我有点被困在这个...... ReferenceTable溢出(max = 512),我确定它与我在本机方法调用中创建的本地引用数有关...为了解决这个问题,我甚至尝试从本机调用中删除本地引用;但我仍然无法解决问题......我正在传递2D数组;大约是1024 X 1024 ......
以下是我所指的错误跟踪...我确定创建的整数对象数量导致我的情况出现问题......因为您应该能够看到506(I)对象已创建。 ..然后JNI遇到了瓶颈......

以下是我使用的代码: 请让我知道我做错了什么?
JNIEXPORT jboolean JNICALL Java_pv_ndk_UcMobile_losInitialization
(JNIEnv * env, jobject jobj , jint height, jint width , jobjectArray elements){
elevData = new unsigned int*[height];
for(i=0; i< height; i++) {
elevData[i] = new unsigned int[width];
jintArray oneDim=
(jintArray)env->GetObjectArrayElement(
elements, i);
jint *element=env->GetIntArrayElements(oneDim, 0);
for(j=0; j< width; j++) {
elevData[i][j]= element[j];
}
// This does not seem to be providing with the desired result
// env->DeleteLocalRef(element);
//I even tried with this approach
env->ReleaseIntArrayElements(oneDim, element , 0);
}
return losObject.Init(elevData,1,10,2,2);
}
答案 0 :(得分:5)
您需要从oneDim
对象中删除本地引用:env->DeleteLocalRef(oneDim);
。
