Android permission WRITE EXTERNAL STORAGE doesn't work even if I have declared it

Question

My Targeted SDK is 22! When I try to write external storage a toast is shown says:

java.lang.SecurityExeption: need WRITE_EXTERNAL_STORAGE permission to use DESTINATION_FILE_URI: uid 10504 does not have android.permission.WITE_EXTERNAL_STORAGE

This is the Error:

Can Anyone help?

Answer 1

I think need Fyber.init();

Fyber sdk is seem to change permission

Answer 2

You can try to analyze apk file from android studio. Check AndroidManifest.xml, see which uses-permission's placed there.

Answer 3

您必须检查自己的库，因为有一个库阻止了您的许可，所以您应该使用“ tools：replace =“ maxSdkVersion” android：maxSdkVersion =“ 27”强制执行该许可。
