Add sdk tools to path in Android Studio app

I have just installed Android Studio 0.2.2 and want to add the sdk tools to path which are in this folder;

/Applications/Android Studio.app/sdk/tools

so that i can use them with e.g. Phonegap.

But after i add this folder to path it still keeps saying:

android: command not found

Oddly, i can't run any of the executables in that folder even when i cd to that folder and type their names.

What am i doing wrong?
