As a related issue, Android Device Monitor is not showing anything in the File Explorer view. This is only occurring on Virtual Devices running Android API Level 24+.
If the standalone SDK Manager has been depreciated, and as a result we are not getting new SDK packages because the SDK Manager does not understand how to process or update them, then we have a problem. This seems to be why I have been having Emulator problems. I seem to be OK, when using an Emulator based on API 23 or less.
I'm just starting to work through this. Does anyone else have any further information re the depreciation of the standalone SDK Manager? If Google is not going to continue maintaining it, we will have to update the SDK by some other means.
