I have had this problem for a while and I thought I would just repost this because there isn't really a solution for this problem around. I just installed android studio 2.1.3 and I have been having this problem:
Could not identify launch activity: Default Activity not found Error while Launching activity
... I have this problem with existing projects BUT I also have this problem when I make a new project ?? What am I doing wrong ? And I've tried all suggested solutions and nothing seems to be working. Any idea's ? Thanks !
Little sidenote, all these projects worked perfectly so I don't think this is a namespace or any other typo problem. And the fact that new projects don't even launch makes it even weirder...
