android使用百度定位SDK 定位主要有以下几步&＃xff1a;
2.导入jar包及SO文件
3.配置androidManifest权限及服务
加入权限 :
在application标签下加入授权码:(每个授权码对应一个应用&＃xff0c;需要自己申请)
android:name&＃61;"com.baidu.lbsapi.API_KEY"
android:value&＃61;"4ff8I8uXAuHPtpgyVw0GfUvY" />
部署定位服务
android:name&＃61;"com.baidu.location.f"
android:enabled&＃61;"true"
android:process&＃61;":remote" >
4.调用提供的接口
package com.util.location;
import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.location.LocationClientOption.LocationMode;
