cordova linux 安装并编出第一个demo-android

cordova可以做到一次编写到处运行各个平台（android、ios、wp、bb、firefoxos、web等几乎所有平台）

手上只有一个android手机，安装的时候没有那么顺利，第一大问题就是网络问题，需要FQ

按照官方提示http://cordova.apache.org/#getstarted

1、首先安装node.js

参考：http://www.cnblogs.com/zhishuai/articles/8138046.html

1 2	`curl --silent --location https://rpm.nodesource.com/setup_8.x \|` `sudo` `bash` `-` `sudo` `yum -y` `install` `nodejs`

2、安装cordova

1	`npm` `install` `-g cordova`

3、创建一个应用、添加android平台

1	`cordova create MyApp <br>cd` `MyApp<br>cordova platform add<br>`

备注：查看平台命令

1	`cordova platform`

出现如下平台

Installed platforms:
android 7.0.0
Available platforms:
browser ~5.0.1
ios ~4.5.4
osx ~4.0.1
windows ~5.0.0
www ^3.12.0
4、编译android版本的时候问题来了，提示android环境没有安装

1	`cordova run android`

Android Studio project detected
(node:30829) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Failed to find 'ANDROID_HOME' environment variable. Try setting it manually.

[app@localhost test]$ cordova run android

[app@localhost test]$ echo $ANDROID_HOME
各种环境变量找不到
1、java没装

2、android没装

------------------------------安装android开发依赖环境----------------------------------------------------

1、安装 java

这里下载jdk：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

http://download.oracle.com/otn-pub/java/jdk/8u151-b12/e758a0de34e24606bca991d704f6dcbf/jdk-8u151-linux-x64.rpm?AuthParam=1514477816_4cd93965dc16fe41a06d861aeab9a333

1	`rpm -ivh jdk-8u151-linux-x64.rpm`

设置环境变量

1	`vim ～/.bash_profile`

添加：

1	`export` `JAVA_HOME=/usr/java/jdk1.8.0_151`

保存退出后使环境变量生效

1	`source` `~/.bash_profile`

2、安装android

下载android-studio

FQ速度有点慢花了好一会时间理论上国内有下载好的之后我也会分享到我的百度云

链接: https://pan.baidu.com/s/1qXTRMfq 密码: jisc

https://developer.android.com/studio/index.html#downloads

解压并运行

1	`android-studio/bin/studio.sh`

启动会自动下载 sdk ，但是默认只下载最新的sdk 我的cordova就不能用需要手动下载对应老一个版本的sdk 。android-studio左上角有一个下载箭头+android的一个图标，点击可以勾选下载对应的sdk

设置环境变量

默认下载到当前用户下$HOME/Android/Sdk

设置环境变量

1	`vim ～/.bash_profile`

添加：

1	`export` `ANDROID_HOME=$HOME/Android/Sdk`

保存退出后使环境变量生效

1	`source` `~/.bash_profile`

-----------------------------------接着cordova---------------------------------------------------------

1	`cordova run android`

会默认下载各种环境，最后下载完之后会生成一个apk 最终生成在工程名test/platforms/android/app/build/outputs/apk/debug/app-debug.apk

我的输出：

...
