打debug包
进入工程目录执行
cordova build android
如果cordova环境配置正确了，会先下载一些安装包
可能会出现如下错误：
* What went wrong:
A problem occurred configuring project ':CordovaLib'.
> You have not accepted the license agreements of the following SDK components:
[Android SDK Platform 27].
Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html
因此尝试装下
Android SDK Build-Tools 27.0.3 (build-tools;27.0.3)
安装完毕再次执行：
cordova build android
测试包生成成功！！！
生成debug目录在：
/Users/wecloud/android-workspace/cordova-demo1/platforms/android/app/build/outputs/apk/debug/app-debug.apk
release 安装包：
cordova build android --release
release安装包生成成功
/Users/wecloud/android-workspace/cordova-demo1/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk
签名重点来了（前面一篇文章生成了appcan.keystore和对应的别名appcan）
jarsigner -verbose -sigalg SHA1 withRSA -digestalg SHA1 -keystore release-key.keystore /Users/wecloud/android-workspace/cordova-demo1/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk cordova-demo这一步没有新的文件生成，只是改变了app-release-unsigned.apk内容，因此需要执行下一步，压缩apk
apk对齐处理(压缩和优化)
对签名后的.apk文件进行对齐处理，不进行对齐处理不能发布到Google Market（使用工具zipalign）
zipalign -v 4 /Users/wecloud/android-workspace/cordova-demo1/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk cordova-demo1.apk
如果提示zipalign找不到
因为我电脑里面装了android sdk 2个版本，因此需要指定一个版本的zipalign
/Users/wecloud/Library/Android/sdk/build-tools/27.0.3/zipalign
重新执行压缩命令：
/Users/wecloud/Library/Android/sdk/build-tools/27.0.3/zipalign -v 4 /Users/wecloud/android-workspace/cordova-demo1/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk cordova-demo1.apk
自动打包(cordova build --release)
新建文件build.json
内容如下：
{
"android": {
"release": {
"keystore": "release-key.keystore",
"alias": "cordova-demo",
"storePassword": "217891qqqq",
"password": "217891qqqq"
}
}
}
