If you got this after mistakenly "Cancel"-ing when you must have selected Remember my choice
then some dirty fix would be to:
Manually copy the same debug apk from your build output to the same test phone.
Manually install the apk. (You have to allow installation from unknown sources of course)
Go to "App Manager" and clear preferences.
Restart the debug as usual.
NB: This was put up in a hurry after some wasted hours so, I'm yet to verify if step #3 is necessary for this to work.
NBB: You'd be back to square one if you uninstall the app and try to do a fresh install from the debug so, apparently, the App Manager
preference reset doesn't cover whichever subsystem it is that governs the setting.
Yes, I know, this should infer that our first #NB is void but things don't always follow intuition so, I'm leaving it till it's verified. :D
