android 前后台保活 实现定位数据定时上传并展示轨迹 （下）
上一篇地址： https://blog.csdn.net/qq_40803752/article/details/86304508
上2篇写完了，保活。这一篇写进入业务逻辑。
大概5分钟定一次位置，上传到服务器。并且展示。
定位的话，我这里使用的百度定位，说下一我写的时候一个逻辑错误，就是每次只定一次位置，担心百度定位那个持续定位
不能用，后面测试发现没有这个问题。gps定位基本一样的。 也是通过 保活维护着定位监听。下面放代码,
//定位

boolean sign=false;

启动代码就不发了，下面发展示代码。比较简单
xmL:

return;
}

}
}
/**

*/
public void setPositionCenter(LatLng latLng) {
// LatLng mLatLng= new LatLng(latitude,longitude);

Gps，实现后面单独写一篇。包括声音地图，高仿户外app。
