安卓开发笔记①：利用高德地图API进行定位、开发电子围栏、天气预报、轨迹记录、搜索周边（位置）
△
高德地图开发时需要导入的包在下面的网盘链接中：（由于高德地图api更新得太快，官网上最新的包使用起来没有之前的方便，所以以下提供最全面的原始包）
链接：http://pan.baidu.com/s/1eR8Nchc 密码：be1v
其中armeabi这个文件夹和其他4个jar是必要导入的，另外两个文件夹确保兼容性。
①首先登陆高德lbs开放平台获取Key，下面是官方详细教程：
http://lbs.amap.com/dev/ticket#/faqcat/1
（本人使用的是eclipse，所以获取安全码SHA1的方法为Windows->preferences->android->build,如下图所示的SHA1 fingerprint）
然后你要设置你所开发的app的包，即在下面的Package中输入你的app包名（这点不能输错）
②申请到key之后，修改安卓项目的AndroidManifest.xml文件，即获取相关的权限和导入key（才能正常启动高德地图）
11个
还有加一个
下面的代码都是调试所用，所有信息都将在logcat栏目里面显示。
③进行定位：
