我有两个函数,我得到一个 ReferenceTable 溢出。消耗的数组条目的摘要是:
1 of byte[] (3 elements)
446 of byte[] (75 elements) (2 unique instances)
576 of byte[] (147 elements) (2 unique instances)
1 of int[] (25 elements)
我真的检查了代码,发现有错误,但没有发现。我得到它们后释放数组。唯一的问题是这些函数被调用了数千次,这可能是原因吗?
这是我所有的本机代码:
调用一次:
JNIEXPORT void JNICALL Java_ar_com_teasoft_Image_nativeUnlock(
JNIEnv *env, jclass clazz, jobject bitmap) {
AndroidBitmap_unlockPixels(env, bitmap);
}
调用一次:
JNIEXPORT jlong JNICALL Java_ar_com_teasoft_Image_nativeLock(
JNIEnv *env, jclass clazz, jobject bitmap) {
int ret;
AndroidBitmapInfo info;
if ((ret = AndroidBitmap_getInfo(env, bitmap, &info)) < 0) {
LOGE("AndroidBitmap_getInfo() failed ! error=%d", ret);
return 0;
}
if (info.format != ANDROID_BITMAP_FORMAT_RGBA_8888) {
LOGE("Bitmap format is not RGBA_8888!");
return 0;
}
void* bitmapPixels;
if ((ret = AndroidBitmap_lockPixels(env, bitmap, &bitmapPixels)) < 0) {
LOGE("AndroidBitmap_lockPixels() failed ! error=%d", ret);
return 0;
}
return (jlong) bitmapPixels;
}
多次调用:
JNIEXPORT void JNICALL Java_ar_com_teasoft_Image_nativeCopyPixels(
JNIEnv *env, jclass clazz, jlong dataRef, jintArray sourceIndexes,
jintArray targetIndexes, jint count) {
argb* sourcePixels;
argb* targetPixels;
jint *sourceArray = env->GetIntArrayElements(sourceIndexes, NULL);
jint *targetArray = env->GetIntArrayElements(targetIndexes, NULL);
for (int i = 0; i < count; i++) {
sourcePixels = (argb*)((char*) dataRef + sourceArray[i] * 4);
targetPixels = (argb*)((char*) dataRef + targetArray[i] * 4);
(*targetPixels) = (*sourcePixels);
}
env->ReleaseIntArrayElements(sourceIndexes, sourceArray, JNI_ABORT);
env->ReleaseIntArrayElements(targetIndexes, targetArray, JNI_ABORT);
}
多次调用:
JNIEXPORT void JNICALL Java_ar_com_teasoft_Image_nativeGetRGB(
JNIEnv *env, jclass clazz, jlong dataRef, jintArray indexes,
jbyteArray destRgb) {
jint *array = env->GetIntArrayElements(indexes, NULL);
jbyte *dstarray = env->GetByteArrayElements(destRgb, NULL);
int size = env->GetArrayLength(indexes);
char* sourcePixels;
int dstCount = 0;
for (int i = 0; i < size; i++) {
sourcePixels = (char*) dataRef + array[i] * 4;
dstarray[dstCount++] = (*(sourcePixels + 1));
dstarray[dstCount++] = (*(sourcePixels + 2));
dstarray[dstCount++] = (*(sourcePixels + 3));
}
env->ReleaseIntArrayElements(indexes, array, JNI_ABORT);
env->ReleaseByteArrayElements(destRgb, dstarray, JNI_COMMIT);
}
综上所述,好像没有释放的那个,是byte[]的,所以应该是函数nativeGetRGB中的那个。但我找不到错误在哪里。
请帮忙!问候, 胡安·伊格纳西奥
