android studio 获取本机代理ip android studio获取定位

需求详情

• Service中每隔10秒执行一次定位操作(GPS+基站)
• 定位的结果实时显示在E都市 上(要求得到经度、纬度)

Android Studio注册service服务

• 切记android中的服务是需要在项目清单文件中注册的

首先新建service类，将所建的service添加到清单文件中

<service android:name="服务类坐所在的包名.MyService"></service>

具体创建并启动service方法可参考： Android Service与Activity的交互以及Android service服务

APP js中启动service服务示例代码

console.log("****************启动service服务：" + localStorage.getItem("$locationStatus"));
//获取Activity对象
var main = plus.android.runtimeMainActivity();
var Intent = plus.android.importClass('android.content.Intent');
var intent = new Intent();
// Activity绑定我们的service服务
intent.setClassName(main, "io.dcloud.HBuilder.wxapi.SingASongService");
// 设置需要传递的参数
intent.putExtra("userId", localStorage.getItem("$userId"));
intent.putExtra("url", CONFIG.server_url + "/apploginuser-apploginuser/apploginuser-save2.html");
// 启动service服务
main.startService(intent);
localStorage.setItem('$locationStatus','1');
console.log("****************启动service服务完毕：" +localStorage.getItem("$locationStatus"));
