java - 从 Glide 下载大图像时出现内存不足错误

Question

这是我尝试下载大图像的代码..

RequestOptions requestOptions = new RequestOptions();
            requestOptions.diskCacheStrategy(DiskCacheStrategy.ALL);
            requestOptions.skipMemoryCache(true);
Glide.with(this)
 .load(rogImage)
 .apply(requestOptions)
 .listener(new RequestListener<Drawable>() {
        @Override
        public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
            return false;
        }

        @Override
        public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
            ProgressBarHandler.unloadProgressScreen(getActivity());
            return false;
        }
    })
    .into(new SimpleTarget<Drawable>() {
        @Override
        public void onResourceReady(@NonNull Drawable resource, @Nullable Transition<? super Drawable> transition) {
            tempImageView.setImageDrawable(resource)
        }

    });

我大部分时间都在 onLoad 失败的方法中结束并出现 OutOfMemoryError。

当我检查设备文件资源管理器时，图像正在下载，但第二次没有加载到 ImageView 中，第一次它非常适合大图像。

我在第二次调用时重复相同的代码。

下面是android studio中给出的实际错误消息。

您可以查看屏幕截图，其中显示图像已下载并存储在设备中。

Answer 1

将其添加到 list 中

  android:largeHeap="true"

另外添加这是app.gradle

 dexOptions {// Prevent OutOfMemory with MultiDex during the build phase
        javaMaxHeapSize "4g"
    }
