Question

我正在分发面包瓦并获得LocalReferenceTableOverflow。它在以下代码中

static void saveBlocks(void *info, BRMerkleBlock *blocks[], size_t count){
__android_log_print(ANDROID_LOG_DEBUG, "Message from C: ", "saveBlocks");
if (!_peerManager){
    return;
}

JNIEnv *env = getEnv();
jmethodID mid;

if (!env) return;

if (count != 1) {
    __android_log_print(ANDROID_LOG_ERROR, "Message from C: ", "deleting %zu blocks", count);
    mid = (*env)->GetStaticMethodID(env, _peerManagerClass, "deleteBlocks", "()V");
    (*env)->CallStaticVoidMethod(env, _peerManagerClass, mid);
}

//call java methods

//Find the class and populate the array of objects of this class
jobjectArray blockObjectArray = (*env)->NewObjectArray(env, (jsize) count, _blockClass, 0);

for (size_t i = 0; i < count; i++) {
    if (!_peerManager) return;

    uint8_t buf[BRMerkleBlockSerialize(blocks[i], NULL, 0)];
    size_t len = BRMerkleBlockSerialize(blocks[i], buf, sizeof(buf));
    jbyteArray result = (*env)->NewByteArray(env, (jsize) len);
    jobject blockObject;

    (*env)->SetByteArrayRegion(env, result, 0, (jsize) len, (jbyte *) buf);
    mid = (*env)->GetMethodID(env, _blockClass, "<init>", "([BI)V");

    __android_log_print(ANDROID_LOG_DEBUG, "huhu", "hier bin ich gleich");
    blockObject = (*env)->NewObject(env, _blockClass, mid, result, blocks[i]->height); // this line
    __android_log_print(ANDROID_LOG_DEBUG, "huhu", "hier bin ich");

    (*env)->SetObjectArrayElement(env, blockObjectArray, i, blockObject);
    (*env)->DeleteLocalRef(env, result);
    (*env)->DeleteLocalRef(env, blockObject);
}

mid = (*env)->GetStaticMethodID(env, _peerManagerClass, "saveBlocks",
                                "([Lcom/breadwallet/presenter/entities/BlockEntity;)V");
(*env)->CallStaticVoidMethod(env, _peerManagerClass, mid, blockObjectArray);
}

logcat的：

谢谢！

本地参考表溢出但使用DeleteLocalRef
