Xamarin.Android.Targets失败，错误为“输入字符串的格式不正确”。

标签： xamarin xamarin.forms xamarin.android xamarin-studio

下面的错误包含“输入字符串的格式不正确。”，我无法弄清楚是什么原因导致了此问题。

如有必要，我可以发布更完整的项目/日志。该项目在iOS上运行良好

2 个答案:

答案 0 :(得分：4)

您需要将 Mainfest.xml 文件中的android:versionCode="1.0"更改为

android:versionCode="1"

它仅接受int，而1.0不是整数。并且在versionName中，您可以放置​​1.1、1.2、1.3等递增版本，以接受string

我有同样的问题。

答案 1 :(得分：0)

就我而言，情况有所不同，我正在设计一个RelativeLayout，并且错误地将其中一个视图的Factor分配为文本而不是整数。

奇怪的是，Xamarin编译器无法指出出现问题的那一行，它指向视图的顶部。

对于任何应该接受整数的Xaml值，您都可以为其分配不同的值，这可能会发生。
