Android （ART） 崩溃并出现错误 JNI 检测到应用程序中的错误：jarray 是无效的堆栈间接引用表或无效的引用

我正在编写一个Android应用程序，用于处理来自本机C（NDK r10d）的图片。在最近的ART引入之前，代码一直运行良好，JNI更严格。因此，该代码在Dalvik上工作正常（例如，在Lolipop之前的设备上），但ii在最新的手机上创建了一个SIGENV。
我现在收到错误：

我在Java中运行的代码是：

    /**
     * Return the raw bytes of the native PIX object. You can reconstruct the
     * Pix from this data using createFromPix().
     *
     * @return a copy of this PIX object's raw data
     */
    public byte[] getData() {
        int size = nativeGetDataSize(mNativePix);
        // Size is usually quite big since I work on pictures (1Mo-300Ko)
        byte[] buffer = new byte[size];

        if (!nativeGetData(mNativePix, buffer)) {
            throw new RuntimeException("native getData failed");
        }

        return buffer;
    }

   private static native boolean nativeGetData(long nativePix, byte[] data);

相应的本机代码为：

jboolean Java_com_googlecode_leptonica_android_Pix_nativeGetData(JNIEnv *env,
        jclass clazz, jlong nativePix, jbyteArray data) {
    PIX *pix = (PIX *) nativePix;

    jbyte *data_buffer = env->GetByteArrayElements(data, NULL);

    l_uint8 *byte_buffer = (l_uint8 *) data_buffer;

     size_t size = 4 * pixGetWpl(pix) * pixGetHeight(pix);
     memcpy(byte_buffer, pixGetData(pix), size);

    env->ReleaseByteArrayElements(data, data_buffer, 0);

    return JNI_TRUE;
}

似乎GetByteArrayElements是错误的来源，但是JNIEnv引用和jbyteArray是由Android提供的，我不存储也不修改它们。由于缓冲区数组总是在同一个Java线程中分配，我不明白它是如何损坏的......我很困惑:)这个问题的根源
是什么？
堆是否太小？还是一个ART问题（我真的怀疑它...）？
感谢您的帮助！


答案 1

按照Alex Cohn的建议，我使以下代码工作：
JAVA

public byte[] getData() {
       byte[] buffer = nativeGetData(mNativePix);

        if (buffer == null) {
            throw new RuntimeException("native getData failed");
        }
        return buffer;
  }
  private static native byte[] nativeGetData(long nativePix);


本地

jbyteArray Java_com_googlecode_leptonica_android_Pix_nativeGetData(
        JNIEnv *env, jclass clazz, jlong nativePix) {
    PIX *pix = (PIX *) nativePix;
    // Get the size
    size_t size = 4 * pixGetWpl(pix) * pixGetHeight(pix);

    jbyteArray  result = env->NewByteArray(size);
    if (result == NULL) {
        LOGE("Cannot allocate JNI Byte Array");

        return NULL; /* out of memory error thrown */
    }
    // move from the Pix to the java structure
    env->SetByteArrayRegion(result, 0, size,(jbyte*)pixGetData(pix));
    return result;
}


谢谢！


答案 2

这意味着它在当前线程中当前本机方法的持续时间内有效。即使对象本身在本机方法返回后继续存在，引用也是无效的。

尝试在你的 jclass/jarray 声明中替换它。

jclass localClass = env->FindClass("MyClass");
jclass globalClass = reinterpret_cast<jclass>(env->NewGlobalRef(localClass));
