Ionic Android Build失败

Question

我开始进行混合开发，我选择了cordova和离子开始。 我正在关注离子文档。 然而，在创建一个新的离子项目并添加android作为平台之后，我在尝试构建android平台时反复失败。 我一直试图解决这个问题好几天了。 请帮助我，以便我可以推进一些实际的发展。

Answer 1

我终于能够通过进入C:\\todo\\platforms\\android\\ant-build文件夹来解决它，其中todo是我创建的离子项目的名称，并将classes.dex.d文件重命名为classes.dex

Answer 2

在一般的cordova中，我可能试图删除平台并使用命令行重新添加它。

cordova platform rm android

cordova platform add android

但是，我很高兴你找到了解决办法。

Answer 3

很高兴你能搞清楚！ 我发现做离子android和ios构建的最简单方法是通过intel xdk。 如果你已经有一个离子项目，你可以将它作为一个intel项目导入，它有一个内置的设备模拟器和构建服务器。 只需点击构建并自动完成该过程。 它还为您处理所有配置文件，并为您提供了一个很好的编辑它们的UI。 https://software.intel.com/en-us/html5/tools

Answer 4

要解决问题，请确保成功安装Android SDK，如果是

1）从cordova项目目录（cd ..）返回2）然后进入cordova项目目录并使用“cordova platform add android --save --fetch”获取3）如果没有出现错误，请尝试删除平台并再次添加

这个对我有用
