From: Eric Schmidt android:versionCode value does not necessarily have a
strong resemblance to the application release version that is visible to the
user (see android:versionName, below). Applications and publishing
services should not display this version value to users.
+ Warning: The greatest possible value for
+ android:versionCode is MAXINT (2147483647). However, if
+ you upload an app with this value, your app can't ever be updated.

android:versionName — A string value that represents the
release version of the application code, as it should be shown to users.
