Fresco以编程方式将Bitmap添加到Cache

Question

我正在将图像上传到我的服务器,一旦上传,我的服务器就会响应新的URI(可以是与旧URL相同的URL),我想删除旧的缓存图像并为新URI插入新图像.

我试着这样做:

// Retrofit2 onResponse

String newImageUri = response.body().getUri();
String oldImageUri = Preferences.getUser().getImageUrl();   

// Remove old image from cache
Fresco.getImagePipeline().evictFromCache(Uri.parse(oldImageUri));               
Fresco.getImagePipeline().evictFromDiskCache(Uri.parse(oldImageUri));
Fresco.getImagePipeline().evictFromMemoryCache(Uri.parse(oldImageUri));
Fresco.getImagePipelineFactory().getMainFileCache().remove(new SimpleCacheKey(oldImageUri));

// Insert new image at new URI
try {
    Fresco.getImagePipelineFactory().getMainFileCache().insert(new SimpleCacheKey(newImageUri), new WriterCallback() {
        @Override
        public void write(OutputStream os) throws IOException {
            os.write(imageData); // byte[] or the new Bitmap
        }
    });
}
catch (Exception e) {
    e.printStackTrace();
}
uriProfileImage.setImageURI(newImageUri);

没有例外,但我仍然只看到旧图像.

我解决了，这是新 Uri 的 Uri 格式错误...
