根设备上的Android权限被拒绝

Question

Not sure why, but I can't run an APK after I've downloaded it onto a rooted device.. Any ideas? I am trying to create an auto-updater for our in-house app but I can't get it to work!

Answer 1

Rooting the device doesn't automatically open up everything - directory and file permissions are still applied against processes based on the 'user' they run as.

Options:

• Install a file manager app that is root aware and use it to move the apk file to somewhere more normal, like the downloads folder.
• Use ADB to move the file somewhere more accessible.

Answer 2

Figured it out eventually.

Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads).ToString()

That gets you to a place it will work.

Thanks for your help.
