Thanks i take noteHere's a summary:
- the private key stands more for the creator (you) of the app. So it is created once for all of your future apps.
- so you can only update using the same key and a different (higher) version (so loosing the key = no updates anymore = new app)
- if you create several apps, you will use the same private key for all apps
- each app must have a unique package name as it competes with all other apps
- example: us.petersmith.app1, us.petersmith.app2, us.petersmith.app3 (all with the same private key to identify you as the creator)
When I start a new app, I change the package name at once to a unique one (de.xxxxx.mynewapp). The folder where I save the code and the sourcecode has the same name. Very easy. No confusion.
Important: Save the private sign key twice! If it get's lost, you are in trouble (at least you can't update a previous version. It is handled as a new version).
Well, starting this year, I had to upload a new App, Created, compliled, uploaded, no problem.Android market doesn't accept APK files signed with this key.
