Recovering aia from installed App

For some reason I lost the .aia of an app that is installed and running on my cell phone. I can't find the apk on the cell itself. Is there any chance to recover the .aia file?

Simple answer: NO way.

Hello renato

Have you changed your email address? If so, is it possible that you have two App Inventor accounts?

It sounds like you have not been saving back-up copies of your .aia files......

No, working with AI2 I always use the same account. For some reason I can't find my .aia of an app. I can't find it in my backups here on the PC. I probably had it transferred to the trash and deleted. I thought you could get it from AI2 backups. If is not possible no problem.
