我正在尝试压缩图像，然后将其上传到Firebase存储。我迷恋发现的this tutorial on youtube。我被告知遵循，但是当我测试所有应用程序时，该应用程序停止运行，并且收到此错误消息，提示Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=8478, uid=10163 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()。我已经添加了permisson来读取外部存储，所以我不确定这是怎么回事。有人可以帮我解决这个问题吗？
