Account Set-Up and retrieving your API Key

Before we can get started with implementing the SDK, you should retrieve your API Key for your integration from the BitLabs Dashboard. If you haven't created an account yet, you can do so here and follow the instructions for the dashboard starting with Sign up & Set up.

App-level build.gradle file

Add the following code above the dependencies section of your app-level build.gradle file:

repositories {
   maven {
       url 'https://jitpack.io'
   }
}

repositories {
   maven("https://jitpack.io")
}

Adding Dependencies

dependencies {
   // other dependencies
   // Note that the artifactId has changed here
   implementation 'com.github.BitBurst-GmbH.bitlabs-android-library:core:2.2.9
'

   // other dependencies
}

dependencies {
   // other dependencies

   implementation("com.github.BitBurst-GmbH.bitlabs-android-library:core:2.1.1")

   // other dependencies
}

Allowing your App to access the internet

If your app doesn't have this already, make sure to allow access to the internet.

//App Permissions
<uses-permission android:name="android.permission.INTERNET" />

Initialising the SDK

You must initialise the SDK before you can use it. You can do so with the following code.

BitLabs.init(<Context>, "YOUR-TOKEN", "YOUR-USER-ID");

BitLabs.INSTANCE.init(<Context>, "YOUR-TOKEN", "YOUR-USER-ID");

The <context> is used to get the device Advertising Id to support BitLabs Offers. This is where you will need the API key from the dashboard, as you will need to replace "YOUR-TOKEN" with it. For "YOUR-USER-ID", you will need to dynamically insert the user id for each app user. Make sure the id used here is unique and that it does not change, as the user's profile will be stored under this id.

🚧

Deprecation

The older init(), shown below, is deprecated and will be remove in a future major release. You can use it for you need to know that in order to get the most out of BitLabs Offers, you have to to use the new init() function

BitLabs.init("YOUR-TOKEN", "YOUR-USER-ID")

BitLabs.INSTANCE.init("YOUR-TOKEN", "YOUR-USER-ID");

📘

You can also hold the reference of BitLabs.INSTANCE in a global or local variable like this:

Java

BitLabs bitLabs = BitLabs.INSTANCE

And now you can use the library as

Java

bitLabs.init("YOUR-TOKEN", "YOUR-USER-ID");

Using the SDK

Show the Offer Wall to the user

Now it's time to use the BitLabs SDK so that your users can start taking surveys. Call the .launchOfferWall() function to open the Offer Wall/Direct Link. BitLabs will show up and the user will see qualifications or surveys.

BitLabs.launchOfferWall(<context>)

BitLabs.INSTANCE.launchOfferWall(<context>)

The <context> here can be the context of an Activity or of the Application.

👍

That's it!

Theoretically, this is all you have to do. Anything below is optional but can improve the user experience.

Check For Surveys - Check if there's something to do for the user

You can use .checkSurveys() to check if a survey is available for the user. This function will return true whenever there's a survey or a qualification question available for the user. Otherwise, it will return false.

BitLabs.checkSurveys { hasSurveys ->
  if (hasSurveys == null) {
  	Log.e(<TAG>, "Error in HTTP, Check BitLabs Logs")
    return@checkSurveys
  }
	Log.i(<TAG>, hasSurveys ? "Has Surveys" : "No Surveys Available")
}

BitLabs.INSTANCE.checkSurveys(hasSurveys -> {
  if(hasSurveys == null) {
    Log.e(<TAG>, "Error in HTTP, Check BitLabs Logs");
    return
  }
  Log.i(TAG, hasSurveys ? "Has Surveys" : "No Surveys Available");
});

If hasSurveys is null, then there has been an error in the request. It should be logged under the BitLabs TAG.

Get Surveys Natively

You can use .getSurveys() to get available surveys for the user.

BitLabs.getSurveys { surveys ->
  if (surveys == null)
    Log.i(<TAG>, "NULL -  Check BitLabs Logs");
  else {
    Log.i(<TAG>, "Surveys: $surveys");
    surveys.get(0).open(this);
  }
}

BitLabs.INSTANCE.getSurveys(surveys -> {
  if (surveys == null)
    Log.i(<TAG>, "NULL -  Check BitLabs Logs");
  else {
    Log.i(<TAG>, "Surveys: " + surveys);
    surveys.get(0).open(this);
  }
});

The callback's parameter is a List of Surveys. A Survey has the following properties:

Reward Listener - Client Side Callbacks

You can use .setOnRewardListener() to set callback which receives the reward of the user and executes the behaviour you specify.

BitLabs.setOnRewardListener { payout -> Log.i(<TAG>, "Payout of: ${payout}") }

BitLabs.INSTANCE.setOnRewardListener(payout -> Log.i(<TAG>, "Reward payout: " + payout));

This callback is invoked when the user leaves the Offer Wall, and the payout is the total reward the user got since the Offer Wall is opened until it is closed.

📘

At the moment, the reward in this callback is just that of the surveys. For offers, please use the server-to-server callback.

🚧

We highly recommend using server-to-server callbacks instead! Please do not use this in apps where the user can withdraw real currency, as it might be exploitable.
However, if your app stores user data locally and does not sync with a server, this would be an option to still use BitLabs to reward your users.

Tags - Set a list of Tags to receive in your callbacks

You can use .setTags() to pass additional parameters to the SDK you would like to receive in your callback.

val tags = mutableMapOf<String, Any>()
tags["my_tag"] = "new_user"
tags["is_premium"] = true
BitLabs.tags = tags

Map<String, Object> tags = new HashMap<>();
tags.put("my_tag", "new_user");
tags.put("is_premium", true);
BitLabs.INSTANCE.setTags(tags);

🚧

Setting a new Map of Tags will replace the old ones.

Add a Tag - Add single tags to receive in your callbacks

Use addTag() if you want to append new tags to an already existent Map of tags which you already set earlier

BitLabs.addTag("my_tag", "new_user")
BitLabs.addTag("is_premium", true)

BitLabs.INSTANCE.addTag("my_tag", "new_user");
BitLabs.INSTANCE.addTag("is_premium", true);
