"Application not installed" but works fine with debug keystore

Howdy folks

Getting close to releasing my first app but have hit a curious problem.

When I build for Android with the debug keystore everything is fine but when I try and install the app when I’ve used my own keystore it produces an .APK without complaint but then won’t install on the Android device (I get the error “Application not installed” with no other information).

Any ideas as to what’s up?

I’ve gone through the keystore creation process twice and that all seems to be fine.

I r confused!

One thing I have seen mentioned (try it) is that if you have the app already installed on the device, if you try to install over it with a different key, it will fail. Try uninstalling first, then installing.

That said, that doesn’t work for me either (although this is in conjunction with stripping unneeded stuff/permissions from the APK). After I go through the apktool decompile/strip/recompile/sign/zipalign pocedure, the resulting APK refuses to install. Even if I skip the “strip” part.

Uninstalling worked a treat … thank you.

It seems that it doesn’t like overwriting an app of the same name with one with a different key.
