android下利用高德地图获取经纬度等定位信息

第 1 步，配置AndroidManifest.xml

首先，声明Service组件

请在application标签中声明service组件,每个app拥有自己单独的定位service。

1

<service android:name="com.amap.api.location.APSService"></service>

然后，声明权限

Android 6.0及以上系统可以参考Android 6.0权限说明章节。

<!--用于进行网络定位-->

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>

<!--用于访问GPS定位-->

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>

<!--获取运营商信息，用于支持提供运营商信息相关的接口-->

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>

<!--用于访问wifi网络信息，wifi信息会用于进行网络定位-->

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>

<!--这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位-->

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

<!--用于访问网络，网络定位需要上网-->

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

<!--用于读取手机当前的状态-->

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

<!--写入扩展存储，向扩展卡写入数据，用于写入缓存定位数据-->

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

接下来写个demo代码
