I have an App that has to access external storage (logs, etc), and it stopped working since I updated it to Android 10. I found a workaround to set

android:requestLegacyExternalStorage="true"

and it works fine on Android 10 now, but not on Android 11. I heard that this should still work on Android 11 if my app is targeting android 10 (SDK 29), so in my case, it should work. But it doesn't, and I still get deployment failed, permission denied

@yeetyeet From [Manage device storage](https://developer.android.com/about/versions/11/privacy/storage#manage-device-storage), Starting in Android 11, apps that use the scoped storage model can access only their own app-specific cache files. – Cherry Bu - MSFT Jan 14 '21 at 01:56
@CherryBu-MSFT Actually it works if I run it in Relese mode, debug is still not working.. – yeetyeet Jan 14 '21 at 10:29
In android 11,you should request the `MANAGE_EXTERNAL_STORAGE` permission. – Leo Zhu Jan 15 '21 at 08:56
Adding MANAGE_EXTERNAL_STORAGE in manifest doent seem to work. Or did you have any other way in mind? – yeetyeet Jan 15 '21 at 10:58
@yeetyeet You said that it works on Release mode, just not work on Debug mode? It is strange. – Cherry Bu - MSFT Jan 19 '21 at 07:40
@CherryBu-MSFT yes, exactly. It works on Debug without fast deployment as well, haha – yeetyeet Jan 25 '21 at 21:41
@yeetyeet You mean that you have solved your problem now? – Cherry Bu - MSFT Feb 02 '21 at 08:05
