Hi Swapnil,

First of all, apologies for the delay in answering your questions. At this time we only have in-depth tutorials for Unity3D which you can find on on our Tutorials page on our Learn section.

The tutorial there covers logging in users via Facebook, creating a leaderboard and posting and retrieving scores.

We have a new video tutorial specifically for doing challenges in Unity on Youtube which you can view by clicking here. The documentation for this video series is not yet ready as we want to ensure it's quality and ease of use. It should be ready in the next couple of days.

Even though the videos are for Unity, the process is almost the exact same for the Android SDK and can be easily followed, only requests are coded differently while setting up the portal and cloud code are the same regardless of engine.

In Unity a CreateChallengeRequest() looks like:

//we use CreateChallengeRequest with the shortcode of our challenge, we set this in our GameSparks Portal
		new CreateChallengeRequest().SetChallengeShortCode("ticTacToe")
			.SetUsersToChallenge(userIds) //We supply the userIds of who we wish to challenge
			.SetEndTime(System.DateTime.Today.AddDays(1)) //We set a date and time the challenge will end on
			.SetChallengeMessage("I've challenged you to Tic Tac Toe!") // We can send a message along with the invite
			.Send((response) =>
			{
				if (response.HasErrors)
				{
					Debug.Log(response.Errors);
				}
				else
				{
					//Show message saying sent!;
				}
			});

In Java that would be:

Map<string, object> data = new HashMap<string, object>();
data.put("@class" : ".CreateChallengeRequest"); //The type of request we're sending
data.put("challengeShortCode" : "ticTacToe"); //The shortcode of the challenge we created on the portal
data.put("endTime" : "2013-12-31T12:00Z"); //When the challenge ends
data.put("usersToChallenge" : "524c13c7e4b0f3abf2b1ddc0"); //The users we want to challenge
Map<string, object> result = gamesparksApi.send(data); //Send our request

Similarly, to list all running challenges and get information from them your ListChallengeRequest() in Unity looks like:

new ListChallengeRequest().SetShortCode("ticTacToe") //List all challenges with the shortcode "ticTacToe"
			.SetState("RECEIVED") //We only want to get games that we've received
			.SetEntryCount(50) //We want to pull in the first 50 we find
			.Send((response) => //The data we want is stored in the response
			{
				foreach (var challenge in response.ChallengeInstances)
				{
					string challengeId = challenge.ChallengeId;
				}
			}

In Java it would look like:

Map<string, object> data = new HashMap<string, object>();
data.put("@class" : ".ListChallengeRequest"); //List all challenges
data.put("shortCode" : "ticTacToe"); //with the shortcode "ticTacToe"
data.put("state" : "Running"); //Retrieve currently running games
data.put("entryCount" : 100); //Grab the first 100 we find
Map<string, object> result = gamesparksApi.send(data); //Send our request, the data we want is stored in the result.

Hope that helps,

Shane
