            <activity

                android:name=".activities.MainActivity"

                            <category android:name="android.intent.category.LAUNCHER" />
                    </intent-filter>

            </activity>
    </application>

</manifest>

Were in the activity tag would you you import the phone gap activity?

Thanks in advance !

Answer 1

It you have used this tutorial http://phonegap.com/start#android then to fix java.lang.ClassNotFoundException as above you need to check the box next to cordova-XXX.jar in the "Order and Export" tab then you add a dependency for cordova-XXX.jar in Libraries tab at "Configure Build Path".

And of course mainclass's name must be correct at android:name="<main class name>".

Answer 2

I was following the phonegap droid getting started guide In my case, I had created a folder called lib instead of libs. A symptom of this was that I had to manually add the jar to the build path. I removed the jar from the build path, renamed the lib folder to libs and things started working immediately.
