Fresco -如何将图像保存到本地存储

Uri imageUri = Uri.parse("https://example.com/image.jpg");
ImageRequest request = ImageRequestBuilder.newBuilderWithSource(imageUri)
        .setProgressiveRenderingEnabled(true)
        .build();
DataSource<CloseableReference<CloseableImage>> dataSource = Fresco.getImagePipeline()
        .fetchDecodedImage(request, context);

dataSource.subscribe(new BaseBitmapDataSubscriber() {
    @Override
    protected void onNewResultImpl(Bitmap bitmap) {
        // 保存图像到本地存储
        File file = new File(context.getFilesDir(), "image.jpg");
        try {
            FileOutputStream outputStream = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onFailureImpl(DataSource<CloseableReference<CloseableImage>> dataSource) {
        // 图像加载失败
    }
});
