Question

I have a phonegap activity which I want to start via a button press:

shareButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent activity = new Intent(context, GalleryActivity.class);
                context.startActivity(activity);
            }
        });

The problem is: everytime I want to start the activity I get following error:

java.lang.NoClassDefFoundError: net.myns.lib.cutoutcam.GalleryActivity

The activity looks like that:

package net.myns.lib.cutoutcam;
import org.apache.cordova.DroidGap;

import android.os.Bundle;
import android.util.Log;

public class GalleryActivity extends DroidGap {


    private static final String TAG = "GalleryActivity";


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.loadUrl("file:///android_asset/www/index.html");
        Log.v(TAG, TAG+" initialised");
    }


}

The manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="net.myns.cutoutcamPro"
    android:versionCode="32"

        </activity>
        <activity
            android:name="net.myns.lib.cutoutcam.LoginActivity"
            android:label="Share image" >
        </activity>
        <activity

            android:label="Share image" >
        </activity>
        <activity
            android:name="net.myns.lib.cutoutcam.GalleryActivity"
            android:label="All images" >
        </activity>
    </application>

    <supports-screens 
           android:largeScreens="true" 
           android:normalScreens="true" 
           android:smallScreens="true" 
           android:resizeable="true" 
           android:anyDensity="true" />


    <uses-sdk
        android:minSdkVersion="7"
        android:targetSdkVersion="8" />

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />

</manifest>

The GalleryActivity is stored inside a LibraryProject, don’t know whether this makes any difference.

As soon as I replace “extends DroidGap” with “extends Activity” the activity can be started.

Someone knows whats going wrong here?

Found the answer!

I did not copy the cordova-1.8.1.jar to the libs directory directly but to libs/phonegap-phonegap-ce32a3f/lib/android/cordova-1.8.1.jar

So keep in mind: ALWAYS copy jars into the root of libs folder!

Thanks for your help guys…
