安装cordova，安装vue-cli: npm i cordova -g，npm i -g vue-cli 。

使用cordova初始化项目并安装android平台:

使用命令行进入开发目录:
执行: cordova create vueapp此命令会生成vueapp目录，vueapp即是完整的cordova项目

进入vueapp目录:
执行:cordova platform add android执行 cordova build android，会将项目默认的示例打包成apk,目录在 vueapp\platforms\android\build\outputs\apk下，直接copy到手机进行安装即可。注:在进行build过程中，会用到sdk相关平台包，按要求进行安装。

使vueapp项目支持相关插件：

在vueapp目录下执行安装插件命令:

cordova plugin add cordova-plugin-geolocation  #支持手机位置获取
cordova plugin add cordova-plugin-camera  #支持手机相机与相册调用
cordova plugin add cordova-plugin-vibration #支持调用手机振动
cordova plugin add phonegap-plugin-barcodescanner #支持手机扫描二维码

创建Vue项目:

在vueapp目录下:
执行 vue init webpack src
此命令会生成src目录，进入src目录:
执行 npm i

修改src下的index.html，加入cordova.js

修改src下config目录下index.js，使其build生成到www目录下,因为cordova生成app时是读取www目录的内容:

将src下默认生成的HelloWord.Vue中的显示内容删除，直接修改App.vue,代码如下:

<template>
  <div id="app">
    <img :src="imgsrc" width="64" height="64"><br/>
    
    <button @click="getposition(1)">获取位置</button>
    <span>{{msg}}</span><br/>

    <button @click="getimage()">显示本地图片</button>
    <button @click="getcode()">获取二维码</button><br/>
    <span>{{codeinfo}}</span>

    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'App',
  data:function(){
    return {
      imgsrc:'./static/logo.png',
      msg:'cordova not init',
      codeinfo:''
    }
  },
  methods:{
    getcode()
    {
      var me = this;
      cordova.plugins.barcodeScanner.scan(
      function (result) {
          me.codeinfo="We got a barcode\n" +
                "Result: " + result.text + "\n" +
                "Format: " + result.format + "\n" +
                "Cancelled: " + result.cancelled;
      }, 
      function (error) {
          alert("Scanning failed: " + error);
      }
   );
    },
    getimage()
    {
      var me= this;
      navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
          destinationType: Camera.DestinationType.FILE_URI,sourceType:0 });

      function onSuccess(imageURI) {          
          me.imgsrc = imageURI;
      }

      function onFail(message) {
          alert('Failed because: ' + message);
      }
    },
    getposition:function(val)
    {
      navigator.vibrate(500);
      var me = this;
       var onSuccess = function(position) {
        me.msg='Latitude:\t'          + position.coords.latitude          + '\n' +
              'Longitude:\t'         + position.coords.longitude         + '\n' +
              'Altitude:\t'          + position.coords.altitude          + '\n' +
              'Accuracy:\t'          + position.coords.accuracy          + '\n' +
              'Altitude Accuracy:\t' + position.coords.altitudeAccuracy  + '\n' +
              'Heading:\t'           + position.coords.heading           + '\n' +
              'Speed:\t'             + position.coords.speed             + '\n' +
              'Timestamp:\t'         + position.timestamp                + '\n';
    };

    // onError Callback receives a PositionError object
    //
    var error= function(error) {
        me.msg='code: '    + error.code    + '\n' +
              'message: ' + error.message + '\n';
    }

    navigator.geolocation.getCurrentPosition(onSuccess, error,{maximumAge: 30000, timeout: 30000, enableHighAccuracy: val});
    }
  },
  mounted(){
    document.addEventListener("deviceready", onDeviceReady, false);
    var me = this;
    function onDeviceReady() {
        me.msg="cordova is ready";
    }
  }
