Android中图片的上传成功了，但是打开url报错

想通过手机拍照然后将图片存储到AVFile中，但是在文件管理有中图片，但点击url打开的图片报错

public void storePhoto(String fileName, String path) {
Log.d("Notification_photo", "进入storePhoto方法");
try {
AVFile avFile = AVFile.withAbsoluteLocalPath(fileName, path);
avFile.saveInBackground().subscribe(new Observer() {
public void onSubscribe(Disposable disposable) {
Log.d("Notification_photo", "onSubscribe");
}

            public void onNext(AVFile file) {
                Log.d("Notification_photo", "onNext");
                Log.d("文件保存完成。objectId：", file.getObjectId());
                SharedPreferences.Editor editor = getSharedPreferences("user", MODE_PRIVATE).edit();
                editor.putString("userImgObjectId", file.getObjectId());
                editor.apply();
            }

            public void onError(Throwable throwable) {
                // 保存失败，可能是文件无法被读取，或者上传过程中出现问题
                Log.d("Notification_photo", "onError");
            }

            public void onComplete() {
                Log.d("Notification_photo", "onError");
            }
        });

        AVObject user = new AVObject("user");
        user.add("userImg", avFile);
        user.save();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
