I've been dealing with this simple issue for quite literally six hours. My app was working perfectly fine before but now all of a sudden I'm getting a "Error type 3... Error while launching activity" error. I've rebuilt, cleaned, invalidated, uninstalled and I still haven't been able to get rid of this error. This error occurs for any project I run through my emulator, so its not just pertaining to this project. I'm a beginner so sorry if this is a dumb post but it's just infuriating me at this point. Any help would be greatly appreciated, thanks.
