It would be really nice if there is some easy way to see what have changed in a certain class (or other file) between two releases (1.6 & 2.1 for example). Does anyone know how to do this?
A way to do it online would be great but downloading the code and checking offline would be ok as well.
To see a comprehensive, auto-generated list of differences between API levels, see the diff reports:
I don't think there's easier way then heading to http://android.git.kernel.org/ and browsing to your file on different heads then downloading it to your drive and comparing them manually.
you tagged this question with git, so with git it would be:
git diff 1.6..2.1 -- path/to/classfile
