Hi all, This is an interesting question, but a bit of background first...my company has been developing software for almost 30 years now. We have always been a .net house, but now we're creating Android and iOS apps as well. I don't want to have to write business logic and database access logic for each different platform, and since we're doing cloud apps, we should be able to call web services to get and put data into the database.
We have been using Entity Framework to communicate with SQL Server for our databases, and, as of late, we have been creating Single Page Applications using Breeze and Knockout. We have created RESTful services using the WebAPI, but in working with Breeze, we like how it calls an IQueryable object. My goal is to write-once, and be able to re-use for the mobile development. LINQ really makes things easier in that we don't have to have a specific API call for each entity, but I haven't found the right library, or I'm not using the right keywords for Google to search...I dunno, but all I'm finding are LINQ libraries that work on data already in memory. That means I will have to bring LOTS of data to the mobile device just to work with it, and that's time-consuming and also will quickly eat up storage space...and why should I do that, when I have a powerful SQL Server that can get me only the data I need. An example: Just about every application starts out showing a list of reecords on a grid. (It would require a query that returns an ID, and one or more descriptive fields (like first and last name).) So we know we can create a RESTful API called "getCustomers()" and it would return the list for us to populate the grid. Upon selection of an item, we would then want to make another call to the database to populate a detail screen. We could create another RESTful API called getCustomer(id), for example, and it should return the fields that we need to populate the screen. OR we could use the Entity Framework to create a Customers() object, and use LINQ to get what we want from it, just by modifying the calling URL....which is easy, fun, and cool in the .net environment, and would satisfy my requirements of using the same business code for all platforms. So here's the question: How do you make a call to a RESTful service that returns an iQueryable object from Android (Java)? Is there a Breeze-type of library for Android? What is the best way to do this - create specific RESTful APIs, or is there a way to use this business layer we have already created that's living on the server? -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
