Android Studio - Uri上传到Firebase

Question

我正在尝试使用相机拍照并将其上传到 Firebase 存储。 我的应用程序连接到 Firebase 并通过了依赖项检查。 代码编译正常，当我点击我的按钮打开相机时，它会打开相机并让我拍照。 一旦我拍完照片并单击确定以 go 返回活动，应用程序就会崩溃。 我尝试了几种变体，似乎都以相同的方式结束。 我有正面图像、背面图像和自拍，但我只处理正面图像以便让它工作，然后我将添加背面图像和自拍图片。 我将 Firebase 存储规则完全开放，以便任何人都可以写入它（这是一个没有真实数据的测试环境）。

关于什么会使它崩溃的任何想法？

再次更新了 logcat 信息：

好的 - 提供商问题才是真正的问题。 一旦我解决了这个问题，CharSequence 问题就是我自己创建的一个 make.toast 问题，用于尝试解决提供程序问题。 因此，一旦我修复了两者，就不会再发生崩溃。 它仍然没有将图像文件写入 Firebase，但如果我不能让它自己工作，那是另一个线程。
