android - java.lang.ClassNotFoundException : Didn't find class "com.millennialmedia.android.VideoPlayer" 异常

Question

我最近搬到了 MoPub，这一切似乎都运行良好，除了我开始收到此异常，提示无法找到 com.millennialmedia.android.VideoPlayer。我看了看，它不在 Millennial jar 上(我刚从他们的网站上得到最新的)。我的 AndroidManifest 也提到了那个类，而 Android Studio 也说找不到它。

这就是我所拥有的:

<activity android:name="com.millennialmedia.android.MMActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" />
<activity android:name="com.millennialmedia.android.VideoPlayer" android:configChanges="keyboardHidden|orientation|keyboard" />

在 Android Studio 中，VideoPlayer 部分是红色的。

这是我得到的异常:

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{mypackage/com.millennialmedia.android.VideoPlayer}: java.lang.ClassNotFoundException: Didn't find class "com.millennialmedia.android.VideoPlayer" on path: /data/app/mypackage-1.apk

看最新千禧年媒体documentation , 它看起来像

com.millennialmedia.android.VideoPlayer

不包括在内。这可能是需要进行的更新。
