Answer 1

删除此权限

  <uses-permission android:name="android.permission.CAMERA"/>

我在Android7中执行我的应用程序时遇到了这个错误。经过测试，我注意到用户权限不在项目A中，而是在项目B中，我只在Android5设备中测试过。因此，我删除了project B中的权限，以便在其他针对Android7的设备上运行它，它最终可以打开。

在adition中，我添加了Android建议的文件提供程序代码https://developer.Android.com/training/camera/photobasics.html希望这能有所帮助。
