Android apps overwrite each other

Hello, Unity Team!

I just bought an Android-Pro license for my Unity 3.5 a few weeks ago.

I have developed two android apps. When I try to install them on my phone they overwrite each other when they are not signed. When the are sighned, only one app can be installed. The bundle identifiers are ok. What can be the problem here?

Regards, Carsten.

If you say “The bundle identifiers are ok” you mean they are different?
