Add this to you Manifest File. Every Class should have an Activity mentioned in the manifest.

<activity  android:name=".Game"  
           android:label="@string/app_name">  
</activity>

You need to add a blank Constructor to your Game class.

i.e.

public class Game extends Activity {

    public Game(){

    }

}

So this is happening because you have overridden the constructor

i.e.

public Game(String something){
    this.something = something;
}

You shouldn't do this in Activities and it will have no effect anyway as you can't instantiate an Activity using the constructor
