arcgis for Android(安卓)100.2 加载shp

几个月前就测试了arcgis for Android 100.2。之前也更新了几篇arcgis 相关的。现在继续。

arcgis for Android 100.1 基本操作（缩小放大旋转定位）

arcgis for Android 100.1 在线加载天地图和谷歌地图

1、显示效果

2、实现代码

测试的注意事项，自已看啦

* 数据量大的时候，加载速度比较慢，有时候还没加载出来，一直在找* 最后又pc上软件知道shp的位置，比较好测试** 还有shp 必须有least three files (.shp, .shx, .dbf) 如果有prj文件那就更好。位置准确** 受之前10的版本影响，我一直在找怎么设置投影，其实是多余的。不用设置，接口都没有。里面已经处理好

3、权限

对于新手开发，我每次都强调权限

1、显示效果

2、实现代码
