Cordova App access Denied

When you have an error of Access Denied when adding platform Android in Cordova App, just navigate to the folder location in Terminal by cd LocationOfFolder. Chances are that a user logged in the computer has no permission to a node_models folder of an application. So cd into the project folder, then node_modules then Cordova-android folder and enter chmod -Rv 755* in the terminal or command prompt. Note: if you are using Windows, start a command prompt as an administrator.
