Apps Keystore file reuse

[murdock]

Hi,

I got a question about the keystore file in Android. I made a .keystore file with a private key in it. Can I use this .keystore file for all the applications I make or should I add another private key into the keystore file for each application I develop? I just don't get it when to make a new keystore file and when to make a new private key.

Regards,
Rob
