百度地图绑定库文件
新建一个BindingsLibrary项目，并把刚下载的BaiduLBS_Android.jar添加到项目的Jars文件夹下，更改BaiduLBS_Android.jar的属性中的”生成操作”属性为EmbeddedJar
生成些项目，如果遇到这样的错误：
VersionInfo”: 成员名不能与它们的封闭类型相同
打开项目中的Transforms的Metadate.xml，在<metadata>节点添加如下代码

因为在C#中不能定义和类名相同的类成员（构造函数除外）
创建andorid项目
在项目中创建一个libs文件夹，把下载的百度地图包中的.so文件添加进来，并在属性上设置成AndroidNativeLibrary
添加权限和设置百度地图访问应用Key

android:layout_height
