downloadRegion
启动下载指定 adcode 区域的离线地图,无需调用 open 接口
downloadRegion({params}, callback(ret, err))
params
adcode:
  • 类型:字符串
  • 描述:指定的区域的 adcode 码(在android平台使用区域的cityCode)
shouldContinueWhenAppEntersBackground:
  • 类型:布尔
  • 描述:(可选项)进入后台是否允许继续下载
  • 默认:false
callback(ret)
ret:
  • 类型:JSON 对象
  • 内部字段:
{    status: 0,           //数字类型;取值范围如下:                         // 0:以插入队列,等待中                         // 1:开始下载                         // 2:下载过程中                         // 3:下载成功                         // 4:取消                         // 5:解压缩                         // 6:全部顺利完成                         // 7:发生错误     info: {              //JSON对象;离线包信息,仅当 status 为2时有值        expectedSize: ,  //数字类型;离线包大小,单位:byte        receivedSize:    //数字类型;已下载到本地离线包大小,单位:byte    }              }示例代码var aMap = api.require('aMap');aMap.downloadRegion({    adcode: '110000',    shouldContinueWhenAppEntersBackground: true}, function(ret) {});    function fnDownloadRegion() {
        var aMap = api.require('aMap');
        aMap.downloadRegion({

            adcode: '110000',
            shouldContinueWhenAppEntersBackground: true
        }, function (ret) { alert(JSON.stringify(ret)); });

    };

function fnDownloadRegion()在手机上测试和模拟器上测试没有alert(JSON.stringify(ret));,怎么获取返回的值?
