android - 使用 ionic emulate android 时如何调试

Question

我使用 ionic 创建了一个应用程序:

ionic start MyFirstApp blank
cd MyFirstApp
ionic serve
ionic platform add android
ionic build android
ionic emulate android

除模拟器步骤外，一切都成功。模拟器启动，但我得到“不幸的是，MyFirstApp 已停止”。一切都是全新的，开箱即用，没有更改代码。

接下来呢？我该如何调试出错的地方？

编辑 这是我调用 ionic build android 时显示的输出:

    C:\Users\Colin\Documents\Ionic\MyFirstApp>ionic build android
add to body class: platform-android
Running command: C:\Users\Colin\Documents\Ionic\MyFirstApp\platforms\android\cordova\build.bat

Answer 1

在我看来，一个更简单/更好的解决方案是在 chrome 上使用 chrome://inspect 工具。

1. 使用

   在您的 Android 上启动应用程序

   ionic 运行安卓

2. 打开 Chrome 并转到:chrome://inspect - 这将列出您连接的设备。

3. 像检查任何其他网页一样使用 chrome 开发工具检查应用。
