ANDROID: Cannot resolve method getSupportActionBar()

Question

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);
    }
}

MANIFEST

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

            </intent-filter>
        </activity>
    </application>

</manifest>

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'

    defaultConfig {
        applicationId "com.myapp"
        minSdkVersion 14
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    compileOptions{
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:support-v4:18.0.+'
        compile 'com.android.support:appcompat-v7:18.0.+'
    }

mainActivity is a Java class and as such it should start with a capitol M — slinden77, Aug 07 '16 at 03:00

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

Perhaps try to clean after extending and see if that solves it? – Chris Aug 08 '14 at 07:46

Your activity needs to extend ActionBarActivity (which provides getSupportActionBar).

Remove the support library jars from the libs directory as you already defined the support library in your gradle file.
```
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:18.0.+'
    compile 'com.android.support:appcompat-v7:18.0.+'
}
```
The support library has been updated so I would update your gradle dependencies to: compile 'com.android.support:support-v4:19.1.+'
Android Studio will already notify you but make sure you sync with gradle.
Rather than extending from Activity, extend from ActionBarActivity.

It is simple, just extend AppCompatActivity instead of Activity.

Please Note that you need to change theme to avoid

Exception : You need to use a Theme.AppCompat theme (or descendant) with this activity

while using AppCompatActivity

This will solve the problem:

import android.support.v7.widget.Toolbar;
