我正在尝试在 Android 应用程序中显示 OpenX 广告。我已安装 SDK 并按照此处找到的视频进行操作。一切都很顺利，除非我编辑布局。我经常在错误日志中收到这条友好的错误消息。

我在谷歌上找不到任何帮助，我想知道是否有人以前遇到过这个问题。我的清单设置正确，并且正在运行 android:targetSdkVersion="17"
<activity
android:name="com.openx.ad.mobile.sdk.OXMAdBrowser"
android:theme="@android:style/Theme.NoTitleBar">
</activity>
因此，由于没有构建错误，我可以启动我的应用程序，但它很快就会崩溃并引发一些错误。

其他人遇到过这个问题吗？
其他信息
我正在使用 xml 布局文件的标准代码。我知道我没有指定任何详细信息，但它不应该返回 com.openx.ad.mobile.sdk.views.OXMAdBanner 未能实例化错误。正确的？
