生成Cordova项目，给Cordova加插件

安装Cordova CLI
Cordova命令行工具是由npm包分发的。

安装cordova命令行工具，通过下面步骤：
1.下载和安装Node.js。安装完成后你可以在命令行中使用node 和 npm 。

2.(可选)下载和安装git client, 如果你没有。安装成功后，你可以在命令行中使用git。 这个命令行使用下载git仓库中的资源。

3.安装cordova 模块使用Nodejs的npm工具。cordova模块会被npm工具自动下载
在OS X和Linux上:

$ sudo npm install -g cordova //这里要下载安装cordova，在命令行要等一会

之后我们在命令行输入：

amelon:~ amelon$ cordova  

如果显示的是这种，表明你安装成功了：

Global Commands    create ............................. Create a project    help ............................... Get help for a command    telemetry .......................... Turn telemetry collection on or offProject Commands    info ............................... Generate project information    requirements .......................

Run project                                            (including prepare && compile)    serve .............................. Run project with a local webserver                                            (including prepare)

查看当前cordova安装版本：

amelon:~ amelon$ cordova --v6.5.0 //版本号

生成一个cordova 项目：

amelon:~ amelon$ cordova create helloworld user.example.cordovaCreating a new cordova project.

找到生成的文件，打开目录为：

helloworld/|____config.xml|____hooks| |____README.md|____platforms|____plugins|____www| |____css| | |____index.css| |____img| | |____logo.png| |____index.html| |____js| | |____index.js

加入android平台（ios，browser…）

amelon:~ amelon$ cd helloworldamelon:helloworld amelon$ cordova platform add android --savaAdding android project...Creating Cordova project for the Android platform:    Path: platforms/android    Package: user.example.cordova    Name: HelloCordova    Activity: MainActivity    Android target: android-25Subproject Path: CordovaLibAndroid project created with cordova-android@6.1.2Discovered plugin "cordova-plugin-whitelist" in config.xml. Adding it to the projectFetching plugin "cordova-plugin-whitelist@1" via npmInstalling "cordova-plugin-whitelist" for android               This plugin is only applicable for versions of cordova-android greater than 4.0. If you have a previous platform version, you do *not* need this plugin since the whitelist will be built in.

打开platform就会看到这样的目录：

/platform|android|__android.json|--AndroidManifest.xml|--assets|__build.gradle|--cordova|--CordovaLib|--libs|--platform_www|__project.properties|--res|__settings.gradle|--src|platforms.json

在我们添加Andorid支持平台的时候，Cordova会为我们添加一个默认插件，也就是上面信息中所打印的cordova-plugin-whitelist并且自动在config.xml文件中已经帮我们配置
自己加一个调用照相机的插件：

amelon:helloworld amelon$ cd pluginsamelondeMacBook-Pro:plugins amelon$ cordova plugin add cordova-plugin-cameraFetching plugin "cordova-plugin-camera" via npmInstalling "cordova-plugin-camera" for androidFetching plugin "cordova-plugin-compat" via npmInstalling "cordova-plugin-compat" for androidSubproject Path: CordovaLib

打开plugins目录：

/platform|android.json|__cordova-plugin-camera|--cordova-plugin-compat|--cordova-plugin-whitelist|fetch.json|www

编译并运行：

amelon:plugins amelon$ cordova buildANDROID_HOME=/Users/amelon/Library/Android/sdkJAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/HomeSubproject Path: CordovaLibStarting a new Gradle Daemon for this build (subsequent builds will be faster).Incremental java compilation is an incubating feature.:preBuild UP-TO-DATE:preDebugBuild UP-TO-DATE:checkDebugManifest:CordovaLib:preBuild UP-TO-DATE:CordovaLib:preDebugBuild UP-TO-DATE:CordovaLib:checkDebugManifest:CordovaLib:prepareDebugDependencies:CordovaLib:compileDebugAidl.......................................................:compileDebugShaders UP-TO-DATE:generateDebugAssets UP-TO-DATE:mergeDebugAssets UP-TO-DATE:transformClassesWithDexForDebug UP-TO-DATE:mergeDebugJniLibFolders UP-TO-DATE:transformNative_libsWithMergeJniLibsForDebug UP-TO-DATE:processDebugJavaRes UP-TO-DATE:transformResourcesWithMergeJavaResForDebug UP-TO-DATE:validateSigningDebug:packageDebug UP-TO-DATE:assembleDebug UP-TO-DATE:cdvBuildDebug UP-TO-DATEBUILD SUCCESSFULTotal time: 1.512 secsBuilt the following apk(s):     /Users/amelon/helloworld/platforms/android/build/outputs/apk/android-debug.apk

把platform下的android项目导入androidstudio，运行一下：

//gradle的版本问题，在setting里设置对应的gradle版本即可Error:Failed to open zip file.Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)<a href="syncProject">Re-download dependencies and sync project (requires network)</a><a href="syncProject">Re-download dependencies and sync project (requires network)</a>

编译在运行一下项目：

程序虽然能够正常跑起来，但这并没有什么用处，因为我们自己添加的照相机插件没有利用起来，于是我们写一份自己的html文件去覆盖这个界面文件。网上有现成的，觉得有点丑，自己动手改改，也可以自己写，清楚cordova的调用方法就可以了。

找到android/assets/www/index.html；打开注视全部，把粘贴的复制上去，在运行一次

点击实验一下，调用照相机和相册功能室完全没问题的，失败会走失败的方法，成功会拿到图片的地址，有的模拟器相机是有问题的，有问题的可以用真机测测

这篇久就写到这里吧，第二篇会详细讲讲插件相关的知识，有问题请留言拍砖，大家多多指教…
