cordova platform add android not working while listing Android targets

To work, this cordova command needs to use some programs located into your sdk/tools directory. You need also have installed apache ant.

Then you must add these directories into your PATH system variable:

Background:

• let’s assume you have installed your Android SDK to the c:\sdk\android directory
• you have installed you Apache ant to the c:\tools\apache-ant directory

Then you must create two system variables:

1. ANDROID_HOME with the c:\sdk\android value
2. ANT_HOME with the c:\tools\apache-ant value

Finally, you must modify the PATH variable and add those two to the end of the PATH‘ value:

;%PATH%\tools;%ANT_HOME%\bin;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools

NOTE: for those who uses Linux, the instruction differs a bit.
