Android 百度定位SDKv4.2及6.0_百度定位实例_安卓定位实例

介绍

由于项目需要、前几天一直在研究百度定位的功能、通过不断的实践终于有结果了、不愿意独享

现在我把我的研究成果和大家分享一下、其实百度的 API 已经相当不错了

这之所以要写出来、一是自己做一个笔记、二是以方便一起朋友少走弯路

导入库文件

在相关下载最新的库文件、将liblocSDK4d.so文件拷贝到libs/armeabi目录下

将locSDK4.2.jar文件拷贝到工程的libs目录下、并在工程属性->Java Build Path->Libraries中选择“Add JARs”

选定locSDK4.2.jar、确定后返回、这样您就可以在程序中使用百度定位SDK了

设置AndroidManifest.xml

在application标签中声明service组件、每个app拥有自己单独的定位service

<service 
	android:name="com.baidu.location.f" 
	android:enabled="true" 
	android:process=":remote">
</service>

声明使用权限

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >
</uses-permission>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" >
</uses-permission>
<uses-permission android:name="android.permission.READ_LOGS" >
</uses-permission>
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />

设置AcessKey

使用SDK4.2需要在Mainfest.xml设置Accesskey、设置有误会引起定位和地理围栏服务不能正常使用

必须进行Accesskey的正确设置、设置AccessKey、在application标签中加入

<!-- meta-data需要写在application中 -->
<meta-data
	android:name="com.baidu.lbsapi.API_KEY"
	android:value="3yoD80PlKwMoP9yHHvmhS77k" />

使用基本定位功能

基本定位功能指的根据用户实际需求、返回用户当前位置的基础定位服务

包含GPS和网络定位（Wi-Fi和基站定位）功能、基本定位功能同时还支持结合定位结果的反地理编码功能

离线定位、位置提醒功能和地理围栏功能

            Log.i("dwtedx", sb.toString());
        }
    }
}

到这里一个简单的百度定位demo就可以实现了、那么需要注意的是一定要在 libs 下面引入 armeabi/liblocSDK4d.so
