摘要：Nowdays, there are many map applications that can be accessed through the web. All these applications are accessing different geospatial data stored on server only. The approach to display different geospatial data type, format, and source from local system becomes new topic in hybrid application for Smartphone. File protocol in XMLHttpRequest can be used to access a file from local system in hybrid application. Another approach is using File API provided by Native Application Framework. To incorporate this API, we create two new classes i.e. URI and HybridFileAPI , as a protocol and request class. These classes utilize File API to access a file in Smartphone local system. We starts the discussion with hybrid map application and system architecture to get understanding about components and processes involved in hybrid map application for Smartphone
