Question

I am trying to find out the maximum length of both the android:versionName and android:versionCode attributes of the android manifest file?

Update 08/11/2016 (UTC):

The docs has been updated. Not the old MAX_INT value or the 2000000000.

Warning: The greatest value Google Play allows for versionCode is 2100000000.

Cross-post for visibility here.

It seems there was a recent change in Google, making the maximum versionCode up to 2000000000 only.

Reference post: Google Play Developer Console error: The version code of your APK is high and you risk not being able to update your APK

PS: For those who are planning to provide reference to the official documentation where the mentioned max value is 2147483647, please read the answer first in the post I referenced. It mentions that as of current date (08/10/2016), its still not updated.
