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.
