Question

我真的很困惑。在我尝试将我的软件包从android.app更改为android.support.v4后，我的应用程序崩溃并抛出以下异常：

这是我的机器人清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.k2evil.porschejournal"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity android:name="com.k2evil.porschejournal.FirstScreen" android:theme="@style/AppTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

我尝试了清理项目，并重命名了应用包名称。但它没有用。
