I try to search for it but I just cant. I am running Windows 7 on Lenovo G460 laptop. I tried to install Ubuntu on it but I cannot use Wireless to connect to the internet for some reason.
Is there anyway for me to get a look at Android source code or at least just the Calendar part of it?
You can browse the android source code using their repository browser. If you want to check out a specific project (i.e. download the source), you will need to get the version control system Git. When you have Git running, you can either clone a complete repository using git clone https://android.googlesource.com/projectname.git or just get the HEAD (the most current version of all files, useful if you only want to browse through the source) by doing git clone --depth 1 https://android.googlesource.com/projectname.git.
The project name is the top folder you select on the repository browser, for example platform/packages/apps/Calendar for the Calendar app. Then the full command is git clone https://android.googlesource.com/platform/packages/apps/Calendar.
