Problem: After creating a new Android Project in Eclipse I included cordova jar in the build path and added my html page in assests/www folder and made corresponding changes in MainActivity.java file. But while running application in Android Emulator its showing an error "Unfortunately HelloWorldCordova App has stopped unexpectedly".

android_cordova_eclipse

1. Your MainActivity.java file should be like this

    package com.example.cordovageolocationapi;

    import android.os.Bundle;
    import org.apache.cordova.*;

    public class MainActivity extends DroidGap {

   @Override
	    public void onCreate(Bundle savedInstanceState)
	    {
	        super.onCreate(savedInstanceState);
	        // Set by <content src="index.html" /> in config.xml
	        super.loadUrl(Config.getStartUrl());
	        //super.loadUrl("file:///android_asset/www/index.html")
	    }
    }

2. Add Cordova-version.jar to your project build path.

3. Make www folder inside assets folder and place all your html inside www folder.

4. Copy cordova folder into into eclipse project root folder.

5. Include cordova-version.jar inside libs folder.

6. Copy xml folder from phonegap-2.5.0\lib\android folder and paste in your eclipse project root folder

7. Include the following in your AndriodManifest.xml

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