I thought following statement would get me current version of calculator at least from version 2.3.
git clone https://android.googlesource.com/platform/packages/apps/Calculator
But I was wrong. It’s one of earlier versions. Does anybody know where I can find source code of Calculator for 2.3?
UPDATE: As comments below show, the source above are up-to-date version. I am sorry for the confusion but in my defense, I didn’t think the app in my device was from third party because I manually upgraded the device to 2.3.
Take a look at this:
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android-apps/2.3_r1/com/android/calculator2/Calculator.java/
May be this is what you are looking for.
