android 百度地图 定位示例

1.需要在 http://developer.baidu.com/ 注册开发者(个人或公司)账号 2.需要申请Key 打开网址 http://developer.baidu.com/map/index.php 点击 创建应用,跟流程创建应用app 3.点击相关下载->一键下载 4.调用百度地图的APP 需要在 AndroidManifest.xml 添加 <application android:name="baidumapsdk.demo.DemoApplication" android:icon="@drawable/ic_launcher" android:label="@string/app_name" > 这里需要添加key,创建应用后，会有这个key <meta-data android:name="com.baidu.lbsapi.API_KEY" android:value="6t2yuIFylnRG7ECj1xHYuelY" /> ..... package com.obtk.mapdemo;
