    Edit: Google AdMob does support rewarded ads without mediation.
    You can use this unit id to test it: rewardAd.LoadAd("ca-app-pub-3940256099942544/5224354917")
    Make sure to use FirebaseAdMob v1.51+

    FirebaseAdMob v1.30 adds support for rewarded video ads. Rewarded video ads are video ads where the user is rewarded if he watches the full video.
    How is the user rewarded is up to you. In many games for example, the users will receive an extra life if they watch the video ad.

    Google AdMob do not provide these ads. You need to use the mediation feature to add an ad network that does support rewarded videos. You can see the features that each ad network supports here:
    I've tested it with InMobi.

    The first step is to integrate the third party ad network as explained here: AdMob Mediation (with InMobi)

    Working with RewardedVideoAd is similar to working with InterstitialAds. You first need to call LoadAd. Note that the ad unit is passed to the LoadAd method and not to the Initialize method.

    The ReceiveAd event will be raised when an ad is ready. Now you can call Ad.Show to show the ad. If the user will fully watch the ad then the Rewarded event will be raised.

    Sub Globals
    Private ad As RewardedVideoAd
    End Sub

    Sub Activity_Create(FirstTime As Boolean)
    End Sub

    Sub Activity_Resume
    End Sub

    Sub ad_ReceiveAd
    Log("Ad received. Now wait for the right moment to show the ad.")
    End Sub

    Sub Ad_Rewarded (Item As Object)
    'Item is currently not used
       ToastMessageShow("You are rewarded!!!"True)
    End Sub

    Sub Ad_FailedToReceiveAd (ErrorCode As String)
    Log("Failed: " & ErrorCode)
    End Sub

    Sub Ad_AdClosed
    End Sub

    Sub Ad_AdOpened
    End Sub

    Sub Activity_Click
    If ad.Ready Then ad.Show
    End Sub

    Not sure. Does it happen if you create a new project with only the ads related code?

    I got this problem too, i've test this rewarded video ads more than a week and it's still show error code: 3. Tested with the latest firebase admob lib v1.31 with the same result. I've checked the mediation report and the ads request was reported in that report but with 0,00% fillrate, it looks like the request was not submitted to inmobi server.

    Hi, I have an issue which is driving me mad, as soon as I invoke the Show Method the video plays but the background process restarts the main activity_create which causes all sorts of problems. With interstitial ads the main activity process is paused until the ad is closed and then continues as normal, is there anyway I can replicate this action while the video is playing then resume after it is closed?

    I've answered my own question, had to add a new activicty and pass all the video ad processing to that, still had a lot of problems returning back to the main activity but managed to figure it out :)

    Hi, got another question, is there any way of trapping whether a user has clicked through during or at the end of a video? I know that the rewarded event fires if the video finishes but can you tell if they clicked the ad itself? I am thinking of offering a higher reward other than just watching it.
  17. Erel

    The AdLeftApplication event should be raised when the user clicks on the ad.

    I'm having a look at this and all I seem to get is static interstitials?

    Do I need a specific minimum api (I changed it from 9 to 14 for min & target) or something else ?

    I used the chartboost adapter, not the inmobi one tho.

    The rewarded video counter in admob increases so it's the right ID etc.

    it's ok. setting the floor of admob to 0.01 solved it.
