ANDROID: Cannot resolve method getSupportActionBar()

This thing is driving me nuts. I can't seem to get my app to compile correctly. I have added the support libraries in my app by copying the jar files, dropping them into libs folder, right click and adding them as library.

I have tried extending ActionBaractivity and nothing still not getting that method recognized.

I am using Android studio version 0.8.2.

Class

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;


public class mainActivity extends Activity implements AdapterView.OnItemClickListener {

private DrawerLayout drawerLayout;
private ListView listView;
private String[] navMenuArray;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
navMenuArray = getResources().getStringArray(R.array.navmenu);
listView =(ListView) findViewById(R.id.drawerList);
listView.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_expandable_list_item_1, navMenuArray));
listView.setOnItemClickListener(this);
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//handles what happens when an item in the menu is clicked
Toast.makeText(this,navMenuArray[position]+" was selected", Toast.LENGTH_SHORT).show();
selectItem(position);
}
public void selectItem(int position){
listView.setItemChecked(position, true);
setTitle(navMenuArray[position]);
}
public void setTitle(String title){
getSupportActionbar().setTitle(title);
}
}

compile 'com.android.support:support-v4:18.0.+'
compile 'com.android.support:appcompat-v7:18.0.+'
}

Answer Source

you need to change Activity to ActionBarActivity

public class mainActivity extends ActionBarActivity

ActionBarActivity has been deprecated so please use the following

public class mainActivity extends AppCompatActivity
