高德地图之定位篇-----定位、预测天气、围栏、搜索周边、行踪轨迹

跟集成百度地图一样，首先获取KEY,获取方式（官方的截图）

这篇主要是讲解高德地图定位篇，高德地图定位篇跟高德地图篇是不同的sdk，分离开了。。。

来看下配置流程吧，配置是第一位的

1.从网站下载并解压得到定位包“Android_Location_V1.xx.jar“。2.开发工程中新建“libs”文件夹，将定位包拷贝到 libs 的根目录下。拷贝完成后的工程目录(以 V1.0.4 为例)如图所示：image注意：若您在 Eclipse 上使用 adt22 版本插件，则需要在 Eclipse 上进行如下配置：选中 Eclipse 的工程，右键选择 “Properties > Java Build Path > Order and Export”，勾选 “Android Private Libraries”。3.添加用户 Key。在工程的“AndroidManifest.xml”文件如下代码中添加您的用户 Key。<applicationandroid:icon="@drawable/icon"android:label="@string/app_name" ><meta-dataandroid:name="com.amap.api.v2.apikey"android:value="请输入您的用户Key" /><activity android:name="com.amap.demo.LocationManager" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity>
</application>
4.添加权限。在工程的“AndroidManifest.xml”文件中进行添加，请直接拷贝。<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
5.clean 工程，结束配置。

接下来就开始贴自己总结的代码了，，，

先看自己的配置文件
