adb.exe some when performing Cordova command

Question

Hello, I have prepared the whole environment to work with Cordova:

1. Installed Android Studio, Nodejs, Apache Ant, Java;
2. I configured the environment variables and the PATH

All right. However, every time I execute the command:

cordova emulate android

or:

cordova run android

the file adb.exe is deleted from the folder platform-tools. When I open the cmd and type adb, is informed that is not recognised as a command.

What could be going on? Remembering that I’ve done all the installations via npm.
