i have been trying many online tutorials weeks on how build android app web app using cordova and/or phonegap cli and/or cloud service, keep getting wrong.

i lastly tried use cordova cli follows:

• i downloaded , installed java jdk
• i downloaded android sdk (verified variables java_home, android_home , path)
• i downloaded , installed nodejs
• installed cordova via: npm install -g cordova (which verified version 6.2)
• i created new folder cordova project , entered folder
• i added android platform thus: cordova platform add android when ran: cordova build android, had error here.

i discovered gradle problem , donloaded , used locally @gandhi suggested, had shorter response (the portion in red ink of picture in above link). have been researching in vain , think stuck. run on windows 10, hp notebook, 64-bits, core-i3 cordova build android cli error
