I download latest version phonegap-2.9.1 zip file but it not contain cordova.jar and when i search on google the i got on answer like navigate folder to lib/android/framework d
It seems that in cordova 2.9.1 (and I assume also in phonegap) they made the same change as in version 3.3 :
There is no more cordova.jar, instead you have the sources of cordova in src\org\apache\cordova\api
.
So if you use eclipse, you have to re-do "import existing android project" with your project's path and it should now find two projects, one for your app and one for the cordova api.
