Adding to PATH in a clean Linux Mint install

I needed to add the android sdk tools directory to my path in a clean Mint install. There was no existing ~/.bashrc or ~/.bash_profile. I tried creating a ~/.bash_profile and adding the path but it didn't work, but I had more success when I created a ~/.bashrc.

This is the line I added:

   export PATH=${PATH}:/usr/local/android-sdk-linux_x86/tools
