Inside the onCreate() method, declare an ArrayAdapter named adapter and initialize it with its constructor. Remember tha

"Inside the onCreate() method, declare an ArrayAdapter named adapter and initialize it with its constructor. Remember that ArrayAdapter is a generic, meaning that the type of the items in the array needs to be specified in angle brackets. The constructor takes three parameters: 1) the context (use this), 2) the layout (use android.R.layout.simple_list_item_1) and 3) the array to adapt (use mApps). Can someone please send me the answer?" i am doing exactly as on the course, doesn't accept it?

AppListActivity.java 
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);
    }
}

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

// It is spelled ArrayAdapter, and should include the type within <> as well
ArrayAdopter adopter = new ArrayAdopter(this android.R.layout.simple_list_item_1, mApps);

// Try if this works:
ArrayAdapter<String> adopter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mApps);

setListAdapter(adopter);

Oh, and i forgot... the ArrayAdapter variable should be named "adapter", not adopter...
