java - 即使我已声明，Android 权限 WRITE EXTERNAL STORAGE 也不起作用

Question

我的目标 SDK 是 22！当我尝试编写外部存储时，会显示一个 toast 说：

java.lang.SecurityExeption：需要 WRITE_EXTERNAL_STORAGE 权限才能使用 DESTINATION_FILE_URI：uid 10504 没有 android.permission.WITE_EXTERNAL_STORAGE

这是错误：

任何人都可以帮忙吗？

Answer 1

您可以尝试从 android studio 分析 apk 文件。检查 AndroidManifest.xml，查看其中放置了哪些使用权限。

Answer 2

你必须检查你的库，有一个库阻止了你的权限，所以你应该用 "tools:replace="maxSdkVersion" android:maxSdkVersion="27" 强制许可

Answer 3

我认为需要 Fyber.init();

Fyber sdk 似乎要更改权限
