似乎无法从离子项目生成 APK [英] Can't seem to generate an APK from ionic project

问题描述

我是 ionic 的新手，试图获得一个用于调试的 apk 我在项目目录中使用了以下命令:

i am new to ionic, trying to get an apk for debugging i used the following commands inside the project directory:

ionic cordova platform add android

我确实得到了platforms/android"目录

i did get "platforms/android" directory

然后我使用了:

ionic cordova build android

这就是我所追求的:

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

但是我没有得到承诺的\build\outputs\apk，有什么问题?

but i didn't get the promised \build\outputs\apk, what is the problem?

更新:我安装了android studio并更新了它，仍然得到

UPDATE: i installed android studio and updated it, still getting

(node:12696) UnhandledPromiseRejectionWarning

更新:问题解决了，原来我有java10，它不适用于android，只需安装java8就解决了问题

UPDATE: the problem was solved, turns out i had java10 which wont work with android, simply installing java8 solved the problem

推荐答案

顺便说一句，我没有安装 android sdk，如果这有什么区别?

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

您已经回答了自己的问题.制作安卓APK

You have answered your own question. To make an Android APK

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

此外，您还需要在 Mac 上更新 X-Code 才能创建 IPA.
