Hi!
you can add a strings.xml file in the res/values folder and put your default app-name there.
<string name="app_name">MyApp</string>
and set the file to read only. for lets say, german translation create a folder named values-de in the res folder, place a strings.xml file with:
<string name="app_name">MeineApp</string>
and set it to read only.
In the manifest editor search for the following code:
SetApplicationAttribute(android:label,"$LABEL$")
and replace it by
SetApplicationAttribute(android:label,"@strings/app_name")
I hope i wrote it correct, at the time I have no acess to my PC, it was written from my memory..
Edit: This works as well with other strings/names in the manifest editor (eg name of shortcuts, dream services etc..)
