You're defining mApps twice. Remove the line:

String[] mApps = {"Instagram","Pinterest","Pocket","Twitter" };

Move the line defining the adapter into onCreate and after setContentView. Also watch out for spelling errors. It's ArrayAdapter not ArrayAdopter. Your'e also missing a comma after this:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mApps);

Finally, don't forget to set the adapter:

setListAdapter(Adapter);

still getting errors, whats wrong with this?

import android.app.ListActivity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter;

public class AppListActivity extends ListActivity {

public String[] mApps = {
    "Instagram",
    "Pinterest",
    "Pocket",
    "Twitter"
};


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_app_list);
    ArrayAdapter<String>adapter=new ArrayAdopter<String>(this android.R.layout.simple_list_item_1, mApps); setListAdpter(adopter);

setListAdapter(Adapter);

}

}

Hi Tommy - As I said in the above post, you have a spelling error. It's ArrayAdapter not ArrayAdopter. Also, you still haven't added a comma after this.
