from one screen to another

Hi
I have made a copy off an App found on the Internet. Android activity – from one screen to another screen
My version doesn't work. When I right click on my projekt, choose Run As, and Android Application, the virtual device starts ok, but nothing happens.
What can be wrong?
Here is my App:
package​
​
​
​
​
com.example.lene;
​

import​

android.app.Activity;​

import​

android.content.Context;​

​

​
android.content.Intent;​

import​
​
​
​
​
android.os.Bundle;​

import​
​
​
​
​
android.view.View;​

import​
​
​
​
​
android.view.View.OnClickListener;​

import​
​
​
​
​
android.widget.Button;
​

public​
​
​
​
​
class AppActivity extends Activity {

Button
button;

@Override​

​
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.
main);
addListenerOnButton();
}

public void addListenerOnButton() {

final Context context = this;

button = (Button) findViewById(R.id.button1);

button.setOnClickListener(new OnClickListener() {

@Override​

​
public void onClick(View arg0) {

Intent intent =
new Intent(context, App2Activity.class);
startActivity(intent);

}

});

}
​

}
