1、要实现高德地图的定位,首先要下载高德地图的SDK以及高德地图定位的SDK
下载地址:http://lbs.amap.com/api/android-sdk/download/
http://lbs.amap.com/api/android-location-sdk/download/
2. 注册账号后到控制台应用管理—–>添加应用—->添加key 获取到自己的key值
获取key的具体方法在官网上: http://lbs.amap.com/
具体操作文档:http://lbs.amap.com/api/android-location-sdk/guide/android-location/getlocation
3、通过解压得到.Jar文件并放到libs文件中,手动添加到依赖库中(右键Add As Lirbrary)
4、如果你的地图SDK是3D的需要在main中创建 jniLibs 文件夹并把你解压出来的其他文件放到此处
5、开发环境已经配置好了,接下来就是敲代码了.
在工程的“ AndroidManifest.xml ”文件添加key(自己注册的应用key)和Service
<meta-data android:name="com.amap.api.v2.apikey"
android:value="自己注册的应用key" />
<service android:name="com.amap.api.location.APSService">service>
添加权限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<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.CHANGE_WIFI_STATE">uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE">uses-permission>
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
