Question

I am uploading a new application on Android Market and it warned me that the new version needs higher versionCode. But since I made just a little improvement, I didn’t want to assign version 2 from version 1 instead I wanted to say “1.1” but versionCode doesn’t allow me to type in float numbers.

So I think I can use versionName which is the one shown to the users but still I am wondering how to do it in versionCode as well.

Android doc says :

android:versionCode –

An internal version number. This number is used only to determine
whether one version is more recent
than another, with higher numbers
indicating more recent versions. This
is not the version number shown to
users; that number is set by the
versionName attribute.

The value must be set as an integer, such as “100”. You can define
it however you want, as long as each
successive version has a higher
number. For example, it could be a
build number. Or you could translate a
version number in “x.y” format to an
integer by encoding the “x” and “y”
separately in the lower and upper 16
bits. Or you could simply increase the
number by one each time a new version
is released.

But I didn’t understand the second paragraph.

Thanks.

Answer 1

It means that

1. only integers are valid(1, 2, 5689)

2. you can use any integer, for example build number( it is always positive integer )

3. to upload a new version you should use number that is higher then previous

Also, version code isn’t seen by anyone, except you, so don’t worry. Only version name is exposed, you can set it to any string value(with some length and rational sense restrictions).
