Answer 1

i think you are new in android. try to read error log. oncreate must be like this.

public class SingleActivityCard extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        TextView text = new TextView(this);
        text.setText("Hello World, Android - mkyong.com");
        setContentView(text);
    }
}

Check oncreate method of SingleCardActivity and make sure first line of these method must be super.onCreate(savedInstanceState);

and another one also specify @override above your oncreate method

2 )in console you also facing problem error accepting Connection so you should resetadb from DDMS and restart your eclipse if you again facing same problem then just re create new AVD
