Phonegap

Today I tried phonegap, the flow was :

-install the gui program (PhoneGapSetup-win32.exe)
-create a new project
-on the prj folder, exists a folder called www, drop your html PRJ there
-then to compile for xap/ipa/apk I go to https://build.phonegap.com, made a free account
-zip the www files+folders, upload zip, press build!

FYI login to https://www.adobe.com/account.html

better use https://cordova.apache.org/

http://cordova.apache.org/docs/en/5.0.0/guide/platforms/android/index.html

https://www.npmjs.com/package/cordova


Unfornutaley Phonegap has an important disadvantage: whenever a security update of Phonegap is released, Google Play requires you to upgrade your app. If you have written many apps (like I did), having to recreate all of them (3 times in latest 2 years) is quite annoying. Therefore I would recommend Webview instead.
