Question

我的Xamarin Android应用程序已经投入使用，人们正在从Google Play下载它，一切似乎都很好，除非我在Google Play开发者控制台中遇到以下错误：

java.lang.RuntimeException: Unable to instantiate application mono.android.app.Application:          java.lang.ClassNotFoundException: Didn't find class "mono.android.app.Application" on path: DexPathList[[],nativeLibraryDirectories=[/vendor/lib, /system/lib, /vendor/lib]]

或类似但略有不同的版本：

我的ClassNotFoundException + mono.android.app.Application的谷歌搜索结果为零。根据开发者控制台，它来自Android 4.2和4.4。，不同的设备（HTC，三星......），甚至来自我测试过的设备，一切正常（HTC One）。

有什么想法吗？是单声道的这个错误吗？还是Xamarin？或者我做错了什么？

Answer 1

每当xamarin app安装在设备中时，它就会找到单声道运行时支持lib，如果它没有安装在设备中，那么它将停止运行，所以，如果你没有单声道安装运行，你可以改变一些设置：

Property =＆gt; Android选项

转到打包并只选择一个Bundle程序集到本机代码中，然后转到链接器并选择链接None然后运行它。

我希望它可能有用。
