If your DataSnap Server requires authentication you can use the methods SetUserName and SetPassword to define the credentials. Android App Links use the Digital Asset Links API to establish trust that your app has been approved by the website to automatically open links for that domain. Retrofit performs HTTP requests against an API running on a server somewhere. An Android App Link is a special type of deep link that allows your website URLs to immediately open the corresponding content in your Android app, without requiring the user to select the app. It makes it relatively easy to retrieve and upload JSON. The first step to create a REST connection with your DataSnap Server, which will give me a instance of DSRESTConnection. Using Retrofit 2 for web-services in Android with a.

The proxy generator generates only the DSProxy.java, all the other files part of the DataSnap Connectors are the representation of DataSnap Framework in Java, for example you wonвЂ™t need to parse the DBXReader as JSON object in Java, just because we have the DBXReader class in Java and it parses the JSON object for you.

The generation can be done through command line or via HTTP request on your DataSnap server, and in the video IвЂ™m showing how to do that.

The next step is to create the proxy class for Android using the DataSnap connectors, which is a new feature in Delphi XE2. They are used to the protection of a higher level of constraints and checks for imported data: They want to be sure that the metadata of the data is correct before. The following code represents the GetCountries implementation.ДЇunction TServerMethods1.GetCountries: TDBXReader Importing JSON data from Web Services and Applications into SQL Server (October 2017) There are a number of reasons why database developers or DBAs will regard JSON with suspicion. This method returns a DBXReader and DataSnap will convert this automatically to JSON at the moment the Android app calls this method, but since we will use the new DataSnap Connector to generate the proxy class, we wonвЂ™t need to handle the JSON object and I will explain that after. The second server method is called GetCountries, and returns all the records I have in the COUNTRY table on my InterBase database. The first server method called InsertCountry, connect on my InterBase database and add a new record to the Country table, see the implementation below: function TServerMethods1.InsertCountry(Country, Currency: String Д¬omm := Д¬omm.CommandType := TDBXCommandTypes.DbxSQL ДЇormat('Insert Into Country (COUNTRY, CURRENCY) Values ( ''%s'', ''%s'')', In the video IвЂ™m showing how to create the Server, letвЂ™s take a look at the Server Method implementation.

In order to have other platforms connecting and interacting with your DataSnap Server you need to enable the REST Interface, and for mobile platforms you can use the DataSnap Connectors that generate proxy classes for Android, BlackBerry, Windows Phone and iOS. The video shows all the steps to create the server and the Android application. On the following video IвЂ™m showing how you can create DataSnap REST Server in Delphi, expose server methods and call them from an Android application.
