目前，我们的Android项目的构建时间非常长

对于拥有以下数量资产的Xamarin Android项目来说，这（参见下面的构建日志）是正常的构建时间吗

350个抽绳
210布局文件
65个值的xml文件

你有什么建议来加快构建时间吗？这真让人讨厌

另外，我们还有一个问题，每次更改xml文件中的某些内容时（例如更改布局文件中的颜色时），我们都需要进行干净的构建

以下是我为Android仿真器执行干净调试构建时的构建日志：

对于拥有以下数量资产的Xamarin Android项目来说，这（参见下面的构建日志）是正常的构建时间吗

是的。即使在原生安卓系统中，使用如此多的资产构建它也需要很多时间

你有什么建议来加快构建时间吗

是的，您可以参考以优化构建

每次更改xml文件中的某些内容时，都要进行干净的构建

尝试保存文件并等待几秒钟

目前，我们的Android项目的构建时间非常长

这对于包含

Xamarin.Forms

和所有相应支持库的

Xamarin.Android

应用程序来说是相当正常的。正如您在

性能总结

中所看到的，我们看到大约33秒用于资源解析（

aapt

），15秒用于java编译（

javac

），大约19秒用于dex编译

如果您想进一步深入了解这一点，可以使用

诊断生成输出

，在命令行上手动调用这些命令，并查看每个命令需要多长时间。大部分工作是由Android SDK构建工具完成的，这在某种程度上是一个瓶颈

以下Android Studio文档中还有一些很好的技巧，也可以应用于

Xamarin.Android

项目：

我们还有一个问题，每次更改xml文件中的某些内容时（例如更改布局文件中的颜色时），我们都需要执行干净的构建-->“ConvertResourcesCases”任务意外失败

以下是解决这个问题的一些建议：

确保您对放置项目的文件夹拥有完全权限。
- 如果您正在使用Mac，请确保您的文件在“文件”属性下处于“取消阻止”状态
- 如果您使用的是Windows，请右键单击文件夹，选择
```
属性
```
  ，选择
```
安全性
```
  ，并授予“完全控制权限”
确保根文件夹路径中没有任何非英语字符

你有什么建议来加快构建时间吗

在项目设置中启用
快速部署。
通过添加以下内容，可以在
.csproj
中启用新的
快速部署
功能：

<AndroidFastDeploymentType>Assemblies:Dexes</AndroidFastDeploymentType>

有关加快构建时间的更多详细信息，请参见： . 有这么多资产是的，这需要时间。其次，如果清理和构建对您来说很忙，我建议您重新构建。您是否知道经常发生的问题，一些新代码在重新构建解决方案之前不会更新。它使用旧的代码和值
