Introduction

To work with the Offer Wall Edge using the Fyber SDK you must ensure that you have:

• Decided to integrate the Offer Wall Edge via the SDK.
• Successfully set up your app, properly configured the Fyber SDK. 

Step 1: Enabling the Offer Wall

1. Go to the Dashboard and click through to your selected App.
2. Go to Placements and select the app from the list. Make sure Status is set to On.

3. Select the currency you wish to use for video rewards from the Virtual currency dropdown menu.

4. In the Exchange rate field enter the number of your virtual currency that equates to one Euro or Dollar (depending on the currency you have set in your account settings).
5. Select the Round up low rewards to 1 unit of virtual currency (recommended) if you want to show offers that reward less than 1 of your virtual currency.
   In such cases, its reward rounded up to 1.

6. Click Save to save your Offer Wall configurations.

Step 2: Requesting the Offer Wall

Using the Offer Wall Requester

To make a request for the Offer Wall you must create an instance of an OfferWallRequester through the Create method. You may choose to store the OfferWallRequester instance or use it immediately, chaining methods as in the following example.

using FyberPlugin;

[...]

OfferWallRequester offerWallRequester = OfferWallRequester.Create();

[...]

offerWallRequester.Request();

The call to Request returns immediately. However, the result of the request is asynchronous and is explained in Handling the Fill Response below. 

Controlling Offer Wall Behavior after Offer Redirecting

When a user clicks on offers, they are redirected outside of your app to complete the offers. You can choose to set the behavior by calling the method CloseOnRedirect of the OfferWallRequester, before making the request.

OfferWallRequester.Create()
            .CloseOnRedirect(shouldCloseOfferwall)
            .Request();

By default, Offer Wall remains open. This is equivalent to passing false to closeOnRedirect.

Step 3: Handling the Fill Response

There are two ways of handling the asynchronous response after requesting the Offer Wall.

Select the method that you want to use in your integration.

Handling Response with Events

Handling the response requires dealing with one of three possible scenarios: Fill, No-fill, or Error. The class FyberCallback contains the next events to help:

You must set up some delegates to listen to those events.

In the case of a fill scenario, the AdAvailable event passes an instance of the Ad class that is saved to be used later to show the Offer Wall.

This is illustrated in the following example.

[...]

    private Ad ofwAd;

[...]

    void OnEnable()
    {
        FyberCallback.AdAvailable += OnAdAvailable;
        FyberCallback.AdNotAvailable += OnAdNotAvailable;   
        FyberCallback.RequestFail += OnRequestFail; 
    }

    void OnDisable()
    {
        FyberCallback.AdAvailable -= OnAdAvailable;
        FyberCallback.AdNotAvailable -= OnAdNotAvailable;   
        FyberCallback.RequestFail -= OnRequestFail; 
    }

    private void OnAdAvailable(Ad ad)
    {
        // store ad response
        if (ad.AdFormat == AdFormat.OFFER_WALL)
            ofwAd = ad;
    }

    private void OnAdNotAvailable(AdFormat adFormat)
    {
        // discard previous stored response
        if (adFormat == AdFormat.OFFER_WALL)
            ofwAd = null;
    }

    private void OnRequestFail(RequestError error)
    {
        // process error
        Debug.Log("OnRequestError: " + error.Description);
    }

Handling Response with Callbacks

Handling the response requires dealing with one of three possible scenarios: Fill, No-fill, or Error. The interface RequestCallback contains the next methods to help:

You must create a class that implements that interface.

In the case of a fill scenario, the OnAdAvailable method receives an instance of the Ad class that is saved to be used later to show the Offer Wall.

Consider the following example as a guide to implementing the interface RequestCallback.

using FyberPlugin;

[...]

public class OfferWallRequestCallback : RequestCallback
{
    public Ad ofwAd;

    public void OnAdAvailable(Ad ad)
    {
        // store ad
        if (ad.AdFormat == AdFormat.OFFER_WALL)
            ofwAd = ad;
    }

    public void OnAdNotAvailable(AdFormat adFormat)
    {
        // discard previous stored ad
        if (adFormat == AdFormat.OFFER_WALL)
            ofwAd = null;
    }

    public void OnRequestError(RequestError error)
    {
        // process error
        Debug.Log("OnRequestError: " + error.Description);
    }
}

To receive the response through the implemented RequestCallback instead of through events, you must pass an instance of it, using the method WithCallback, before making the request.

[...]

OfferWallRequestCallback requestCallback = new OfferWallRequestCallback();

[...]

OfferWallRequester.Create()
            .WithCallback(requestCallback)
            .Request(); 

Step 4: Displaying Offer Wall

Once you've received an Offer Wall Ad you can display through its method Start, as in the following example:

private Ad ofwAd;

    [...]

    private void ShowOfferWall()
    {
        if (ofwAd != null)
        {
            ofwAd.Start();
            ofwAd = null;
        }
    }

Offer Wall Notifications

If you want to be notified when the Offer Wall is started and closed this is performed through events or callbacks.

Select the method that you want to use in your integration. 

Handling Notifications Through Events

The class FyberCallback contains the events OnAdStarted to notify that the Offer Wall was opened, and OnAdFinished fired when the Offer Wall is closed.

void OnEnable()
    {
        FyberCallback.AdStarted += OnAdStarted;
        FyberCallback.AdFinished += OnAdFinished;
    }

    void OnDisable()
    {
        FyberCallback.AdStarted -= OnAdStarted;
        FyberCallback.AdFinished -= OnAdFinished;  
    }

    [...]

    private void OnAdStarted(Ad ad)
    {
        if (ad.AdFormat == AdFormat.OFFER_WALL)
        {
            // this is where you mute the sound and toggle buttons if necessary
            ofwAd = null;
        }
    }

    private void OnAdFinished(AdResult result)
    {
        if (result.AdFormat == AdFormat.OFFER_WALL)
        {
            Debug.Log("Ofw closed with result: " + result.Status +
                " and message: " + result.Message);
        }
    }

Handling Notifications Through Callbacks

The interface AdCallback contains the methods OnAdStarted to notify that the Offer Wall was opened, and OnAdFinished fired when the Offer Wall is closed.

The following is an example of how to implement the interface AdCallback for Offer Wall.

public class OfferWallAdCallback : AdCallback
{
    public void OnAdStarted(Ad ad)
    {
        // this is where you mute the sound and toggle buttons if necessary
        Debug.Log("OnAdStarted. Ad " + ad.AdFormat + " has started");
    }  

    public void OnAdFinished(AdResult result)
    {
        // this is the place where you can resume the sound
        // reenable buttons, etc
        Debug.Log("OnAdFinished. Ad " + result.AdFormat +
            " finished with status: " + result.Status +
            " and message: " + result.Message);
    }   
}

To be notified through the implemented AdCallback instead of through events, you must pass an instance of it, using the method WithCallback, before calling Start to show the Offer Wall.

private OfferWallAdCallback adCallback = new OfferWallAdCallback();

    [...]

    private void ShowOfferWall()
    {
        if (ofwAd != null)
        {
            ofwAd.WithCallback(adCallback)
                .Start();
            ofwAd = null;
        }
    }

Step 5: Rewarding the User

There are two options when it comes to rewarding the users with virtual currency:

Option 1: Using your Own Server (Server Side)

If you are interested in using your own server to handle virtual rewarding to your users, Fyber can interact with it after you've set up your own server.

Click here for details on Server-Side Rewarding. 

Option 2: Using the Virtual Currency Server (VCS)

If you do not run your own servers, Fyber can provide you with virtual currency hosting. This is the default setting for mobile applications in the developer Dashboard.

Click here for details on VCS Rewarding.

You must set up the developer Dashboard for the option you choose and add the code necessary on the Unity side

Activating Fyber Logging

Fyber provides custom logging to help you troubleshoot your integration. Activate logging before starting up the Fyber Unity Plugin to ensure you have logs of the startup itself.

Call the following method:

FyberLogger.EnableLogging(true);

Optional Android Method

It is also possible to activate logging on your test devices without having to make the specific call to enableLogging. This is useful if you want to pull your live build from the Google Play Store and troubleshoot it.

You can activate logging via an adb command:

adb shell setprop log.tag.Fyber VERBOSE

After making the adb command, logging will be active on your test device until you disable the logging again. You can disable it again at any time with another adb command:

adb shell setprop log.tag.Fyber SUPPRESS
