Android百度地图开发
按照下面的流程走，带你轻松学会百度地图的基本开发。
1.申请API Key
打开下面的网址
http://lbsyun.baidu.com/apiconsole/key
点击创建应用
填写应用名称为你的Android软件名称；
选择应用类型为Android SDK
SHA1为 打开你的Android studio
点击右侧的Gradle 然后再点击列表中的signingReport
运行结果：
将SHA1复制进去
包名为：在build.gradle(Module:app)中可以找到
点击提交
2.下载百度LBS开发平台的SDK并导入到你的项目中
下载地址
http://lbsyun.baidu.com/index.php?title=androidsdk/sdkandev-download
点击自定义下载，下载开发包
下载列表为：
1)将下面两个jar文件复制到项目文件的lib包里：
然后进行导入操作：
2)在app目录下新建文件夹jniLibs将上面下载的五个文件夹复制到你新进的jniLibs文件夹中
3.接下来就是写代码工作了
1）首先是添加权限
2）然后是在
中添加：
注：其中value值是你刚刚申请的API Key
3）界面代码（xml）
4）java代码
