Adaptive Cards Rendering and Authoring using Java

Question

I am trying to implement an Approval Flow using Adaptive Cards and building an RESTful API in Java to use for Actions in Adaptive Cards.

I was able to validate the token from the Adaptive Card using this.

But in order for my API to send a Refresh Card as a response, i need to author and render the Adaptive Card.

There is an SDK for Android but not for specifically for Java.I have tried to work with adaptivecards-android-1.2.5 aar, but just unable to load the classes.

Is there any SDK for Java or any other way how we can utilize the Android SDK?

Unfortunately there is no plain-Java SDK available at this time. The source code is available here, hopefully you would be able to pull out the parts you need: github.com/microsoft/AdaptiveCards/tree/master/source/android — Matt Hidinger

At the end of the day, although it sounds fancy, an "Adaptive Card" is actually just a JSON string. As a result, even without a good strongly-typed library, you can just create the raw JSON yourself to send, do your own string/token replacements, and send it to the end destination. Just as an example, have a look at this question and the 2nd option in my answer: Display number in adaptive card

As a further suggestion, once it's all working, perhaps you can contribute to a Java version of Adaptive Cards - it is an open source project, after all :-)
