I'm implementing phonegap based application for android and want to call angry birds game from inside the phonegap app. After my quick research here and here I have following:
/src/com.borismus.webintent.WebIntent.java
/www/webintent.js
AndroidManifest:
<activity
    android:name=".MainActivity"
    android:label="@string/app_name"
    android:configChanges="orientation">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <data android:scheme="com.rovio.angrybirds" />
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
        </intent-filter>
</activity>
main.js
function onClickStartAngry() {
    window.plugins.webintent.startActivity({
        action: WebIntent.ACTION_VIEW,
        url: 'have_no_idea'},
        function() {};
    function() {alert('Failed to open AngryBirds App')};
});
}
I'm stuck here and have_no_idea what should be written for url:. Any help? Or there is another way to call for other application from phonegap?
