android - 似乎无法从 ionic 项目生成 APK

Question

我是 ionic 的新手，试图获取一个用于调试的 apk 我在项目目录中使用了以下命令:

ionic cordova platform add android

我确实得到了“platforms/android”目录

然后我用了:

ionic cordova build android

这是我得到的:

     ionic-app-scripts build --target cordova --platform android

You have been opted out of telemetry. To change this, run: cordova telemetry on.

但是我没有得到 promise 的\build\outputs\apk，这是什么问题？

更新:我安装了 android studio 并更新了它，但仍然可以

(node:12696) UnhandledPromiseRejectionWarning

更新:问题已解决，原来我的 java10 不能与 android 一起使用，只需安装 java8 即可解决问题

Answer 1

btw, i dont have android sdk installed if that makes any difference?

您已经回答了您自己的问题。制作 Android APK

• 您需要 Java SDK 1.8。
• 具有最新构建工具和平台的 Android SDK
• JAVA_HOME 和 ANDROID_HOME 环境变量设置正确。

此外，您还需要更新 Mac 上的 X-Code 才能创建 IPA。
