Initialize the Playtime SDK

To make all of the features of the Playtime SDK available, you need to initialize it first. This initialization happens asynchronously in the background, with its completion indicated by a callback method. Make sure to initialize the SDK immediately after the app launches and each time it returns to the foreground.

Best practices for the SDK initialization:

  • Initialize early: Initialize the SDK as soon as possible after your app starts. This ensures all Playtime SDK features are ready for use right away.

  • Initialize after your app authentication: Once a user signs up or logs in, initialize the SDK again with the latest user details. This updates the userID within the SDK.

  • Initialize regularly: For the best user experience, call the init method every time your app comes into the foreground. Doing so will not affect your app's performance.

  • Initialization triggers: Call the init method at the app start and resume (when the app comes back into the foreground).

Initialization

// The initialization will run in the main application process asynchronously in the background and notify you when it is finished by invoking the PlaytimeInitializationListener's onInitialisationFinished or onInitialisationError method.

class MainActivity : AppCompatActivity {
	
    override fun onCreate(savedInstanceState: Bundle?) {
        Playtime.init(this, "sdkHash", options, object: PlaytimeInitialisationListener {
            
            override fun onInitialisationFinished() {
                // the Playtime SDK was initialized successfully
            }
            
            override fun onInitialisationError(exception: Exception?) {
                // an error occurred while initializing the Playtime SDK.
                // note that exception might be null
            }
        })
    }
}

Important: Initialization must happen on the main thread since it's a UI-related action. Calling any of the init methods off the main thread could lead to app disruptions.

Playtime Options

Pass the following additional options to the Playtime SDK during initialization:

Parameter
Type
Explanation

User ID

String

A custom identifier you can assign to each user. If you haven't set one, the Playtime SDK generates it automatically. It is accessible through Playtime.getUserId(Context). This ID is necessary for S2S payouts, thus required. Ensure this value is url-safe and that the value is never empty.

Object

Object

Extensions

Object

val options = Playtime.Options()
    .setUserId(userId)
    .setParams(playtimeParams);
    .setUserProfile(playtimeUserProfile)
    .setExtensions(playtimeExtensions);

Playtime Parameters

When initializing the SDK, you should include additional User Acquisition and Playtime placement parameters. These parameters allow you to track and analyze Playtime's performance within your app.

To make the most of the Playtime SDK, to maximize your revenue and provide the best user experience, use all of these parameters for data-driven optimizations. For instance, you can monitor the performance of different Playtime button placements or determine the effectiveness of different UA sources.

You can provide these parameters in any combination, both at initialization and at any point in the app's lifecycle—such as when a user launches the Playtime Catalog interacts with a campaign or requests a payout.

These values must be url-safe as they could potentially be returned as query parameters in the S2S Payout request.

Parameter
Type
Explanation

UA Network

String

User Acquisition Network. The network through which the user was acquired, e.g., Adwords, Facebook, or Organic.

UA Channel

String

User Acquisition Channel. The channel within the network from which the user was acquired, e.g. incentivized or video campaigns.

User Acquisition Sub Publisher Cleartext

String

The cleartext package name of the sub-publisher's app ID within the network from which the user was acquired, e.g., com.domain.appName.

User Acquisition Sub Publisher Encrypted

String

The encrypted package name or app ID of the sub-publisher's app from the network where the user was acquired.

Placement

String

The placement of the Playtime Catalog inside your app, e.g., "Main Screen", "Shop", "Interstitial", "More Diamonds Screen", etc.

val playtimeParams = PlaytimeParams.Builder()
    .setUaNetwork("network")
    .setUaChannel("channel")
    .setUaSubPublisherCleartext("SubPublisherCleartext")
    .setUaSubPublisherEncrypted("SubPublisherEncrypted")
    .setPlacement("placement")
    .build()
Playtime.setUAParams(context, playtimeParams)

User Profile Information

Our game recommendations are personalized through algorithms that consider users' preferences and gender information. If a user consents to share their gender and/or birthday, you can share this information with adjoe to enhance the customization of game suggestions.

The code below is for demonstration purposes and can be modified to best suit your app's set-up. The important thing is that you get the user's birthday and gender information from your backend and pass in the data to adjoe when initializing.

The birthday data should be in ISO format. If your data doesn't already look like that, please make sure to format it so that it is. Example: 2023-07-17T22:25:00.000Z

fun playtimeUserProfile(): PlaytimeUserProfile {
    val gender: PlaytimeGender = when (getUserGender()) {
        "male" -> PlaytimeGender.MALE
        "female" -> PlaytimeGender.FEMALE
        else -> PlaytimeGender.UNKNOWN
    }

// if you don't know the exact birthday, the year is enough
    val birthday: Date = if (isExactBirthdayKnown()) {
        getUserBirthday()
    } else {
        val calendar = Calendar.getInstance()
        calendar.set(Calendar.YEAR, getYearOfBirth())
        calendar.set(Calendar.MONTH, 0)
        calendar.set(Calendar.DAY_OF_MONTH, 0)
        calendar.time
    }

    return PlaytimeUserProfile(gender, birthday)
}

Playtime Extensions

These are optional identifiers used in your backend. They will be provided back in the S2S payout URL.

val playtimeExtensions = PlaytimeExtensions.Builder()
    .setSubId1("subId 1")
    .setSubId2("subId 2")
    .setSubId3("subId 3")
    .setSubId4("subId 4")
    .setSubId5("subId 5")
    .build()

Checking Initialization

We recommend to verify the SDK is correctly initialized. Each wrapper provides an Playtime.isInitialized method for this purpose. When executed, this method returns true if the SDK is initialized, and false otherwise. Use IsInitialized for debugging or to verify SDK initialization before calling other methods.

Important: Do not call Playtime.init based on the result of isInitialized.The SDK already performs its own initialization checks. Doing so again may degrade the user experience.
