Each android apk file is signed with somebody's private key. I have 
created my own private key with which I sign all of the apks on 

When you build an apk, if you do not create a key, it is signed by a 
development key that is created when you install the development kit. If 
you try to install a new version of an apk that is signed with a 
different signature the system will refuse to do it.

Note the development key is valid for one year. The permanent one like I 
created is valid for 40 years.

So - long story short - you will have to uninstall and install again, 
which will also lose your config.xml file. However if you have set up a 
unique id in the config, you can use the same unique id again and your 
settings from the database will still be found.
