android - getActionBar() 的 NoSuchMethodError 错误 (API-8)

Question

当我运行它安装的应用程序但随后崩溃时，ecplise 并没有告诉我我的代码有什么问题。我认为这是我的 list 有问题...

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.secondapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>                
                <meta-data
                    android:name="android.support.PARENT_ACTIVITY"
                    android:value="com.example.secondapp" />
        </activity>
    </application>

</manifest>

使用支持库 v7 提供的 getSupportActionBar，如 here 所述在 6 上。检索操作栏部分

getSupportActionBar documentation
