When downloading and installing updates from Android Market, you often see an update comment like
and so on. How is that comment made? I couldn't see a update comment field in the market today.
Thanx for listening!
You just add the change comment at the end of your application description, optionally separated by a line of hyphens.
There's no official way of making a specific upgrade comment.
What some devs do (which may explain the examples you've seen) is to add change descriptions to android:versionName in the manifest, as that can be any string.
