离子Android构建失败

Question

我开始从事混合发展，我选择了Cordova和Ionic开始。我正在遵循离子文档。但是，在创建了一个新的离子项目并将Android添加为平台之后，我在尝试构建Android平台时反复失败。我一直在尝试解决这个问题几天。请帮助，以便我可以继续进行一些实际的发展。

Answer 1

我终于能够通过进入C:todoplatformsandroidant-build文件夹来解决它，其中todo是我创建的Ionic Project的名称，并将classes.dex.d文件重命名为classes.dex

Answer 2

在一般科尔多瓦（Cordova）中，我可能试图删除平台并使用命令行重新添加。

cordova platform rm android
cordova platform add android

但是，我很高兴您找到了一个修复程序。

Answer 3

很高兴您能够弄清楚它！我发现进行离子Android和iOS构建的最简单方法是通过Intel XDK。如果您已经有一个离子项目，则可以将其导入Intel项目，它具有内置的设备模拟器和构建服务器。只需点击构建即可自动化该过程。它还为您处理所有配置文件，并为您提供用于编辑它们的不错的UI。https://software.intel.com/en-us/html5/tools

Answer 4

解决问题，请确保已成功安装Android SDK，如果是

1）从科尔多瓦项目目录（CD ..）返回2）然后进入Cordova项目目录，然后使用" Cordova平台添加Android -save-fetch"进行获取3）如果没有出现错误，请尝试删除平台并再次添加

它对我有用
