I am trying to find out the maximum length of both the android:versionName and android:versionCode attributes of the android manifest file?
android:versionCode="185" <--- THIS ATTRIBUTE
android:versionName="1.0.185"> <--- AND THIS ATTRIBUTE
Based on android documentation:
android:versionCode — An
integer value that represents the version of the application code, relative to other versions.
Edit - Android documentation explicitly states -
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.
Based on oracle documentation:
By default, the
int data type is a 32-bit signed two's complement integer, which has a minimum value of -2^31 and a maximum value of (2^31)-1. In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of (2^32)-1.
android:versionName — A
string value that represents the release version of the application code, as it should be shown to users.
String max length, this SO question may help you.
