问题描述

在cordova 中进行测试应用时出现如下问题

$ cordova run android
ANDROID_HOME=C:\Users\Administrator\AppData\Local\Android\sdk
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_66
No target specified, deploying to emulator
Error: No emulator images (avds) found.
1. Download desired System Image by running: "C:\Users\Administrator\AppData\Local\Android\sdk\tools\android.bat" sdk
2. Create an AVD by running: "C:\Users\Administrator\AppData\Local\Android\sdk\tools\android.bat" avd
HINT: For a faster emulator, use an Intel System Image and install the HAXM device driver

问题解决

1. win7 环境下设置环境变量

ANDROID_HOME = C:\Users\Administrator\AppData\Local\Android\sdk;

1. 在当前应用下输入如下命令

$ cordova platform ls
Installed platforms:
  android 5.1.1
Available platforms:
  amazon-fireos ~3.6.3 (deprecated)
  blackberry10 ~3.8.0
  browser ~4.1.0
  firefoxos ~3.6.3
  webos ~3.7.0
  windows ~4.3.1
  wp8 ~3.8.2 (deprecated)

查看所需要的android 5.1.1 的版本

1. 在ANDROID_HOME 中启动SDK Manager.exe 安装 android 5.1.1 需要的image
2. 安装成功后，启动ANDROID_HOME 路径中的AVD Manager.exe，创建一个Android Virtual Device（AVD），并启动
3. 再次运行

$ cordova run android
ANDROID_HOME=C:\Users\Administrator\AppData\Local\Android\sdk
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_66
No target specified, deploying to emulator
