i have this Intent Code:

```
Intent arbeiten = new Intent(this, arbeiten.class);
startActivity(arbeiten);

```

but Eclipse tells me:

```
The constructor Intent(new AdapterView.OnItemClickListener(){}, Class<arbeiten>) is undefined

```

Other (working) Intents in the same Project, but other Class looks like

```
Intent toolb = new Intent(this, ToolBox.class);
toolb.putExtra("json", json.toString());
startActivity(toolb);

```

And they are working...

The "Arbeiten"-Class looks like this:

```
package XXX;
import android.app.Activity;
import android.os.Bundle;

public class arbeiten extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

```
