Action bar is not displayed

I'm making a Twitter app on Android Studio, but when I run it on a real machine, I don't see the action bar where the title of the app should be displayed.
I don't think it's set to not display...
If you know how to solve this problem, please let me know.

The actual machine is Nexus 7.

AndroidManifest

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17"/>

<uses-permission android:name="android.permission.INTERNET"/>


<application
    android:allowBackup="true"
    android: icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    <activity
        android:name="com.example.x_vvx18.twinicooo.MainActivity"
        android: label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

    <activity
        android:name = ".TweetActivity"
        android:windowSoftInputMode="adjustResize"/>
    <activity
        android:name = ".TwitterOAuthActivity"

        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>

        <data
            android: host="twitter"
            android: scheme="zzzakiii"/>
    </intent-filter>
</activity>
</application>

</manifest>

When I changed Android: Theme from App Theme to Widget.AppCompat.ActionBar, which is set to default, ActionBar was displayed.
