Android Question CallSub from Inline Java Class

Jack Cole · Jun 5, 2021

I'm trying to modify the AdsHelper class for traditional rewarded video ads and to add some events. I'm having trouble figuring out how to call a sub in the AdsHelper class from a class within the inline java. Does anyone know how to do this?

B4X:

Sub RewardedAd_ReceviedAd
    Log("RewardedAd_ReceviedAd")
End Sub

Java:

public static class MyRewardedAdCallback extends RewardedAdLoadCallback {
    public RewardedAd ad;
    
    [USER=69643]@override[/USER]
    public void onAdFailedToLoad(LoadAdError adError) {
        BA.Log("Failed to load RewardedVideoAd: " + adError);
    }
    
    [USER=69643]@override[/USER]
    public void onAdLoaded(RewardedAd ad) {
        BA.Log("RewardedVideoAd received");
        processBA.raiseEventFromUI(this, "rewardedad_receivedad", Null);
        this.ad = ad;
    }   

}

Here is what I get:

Compiling generated Java code. Error
src\mindware\mindgames\adshelper.java:1100: error: cannot find symbol
processBA.raiseEventFromUI(this, "rewardedad_receivedad", Null);

I figured out how to do it.

Java:

static String eventName;
static B4AClass target;

   public void setCallback(String s, B4AClass target) {
       BA.Log("setCallback");
       eventName = s.toLowerCase(BA.cul);
       this.target = target;
   }

public static class MyRewardedAdCallback extends RewardedAdLoadCallback {
    public RewardedAd ad;
    
    @Override
    public void onAdFailedToLoad(LoadAdError adError) {
        BA.Log("Failed to load RewardedVideoAd: " + adError);
        target.getBA().raiseEventFromDifferentThread(target, null, 0, eventName + "_failedtoreceivead", false, new Object[] {adError});
    }
    
    @Override
    public void onAdLoaded(RewardedAd ad) {
        BA.Log("RewardedVideoAd received");
        target.getBA().raiseEventFromDifferentThread(target, null, 0, eventName + "_receivead", false, null);
        this.ad = ad;
    }   

}

Here is what I use to set the event/callback module and sub for testing. This is in the AdsHelper module.

B4X:

Public Sub SetCallbackModule(Module As Object, Event As String)
    nativeMe = Me
    nativeMe.RunMethod("setCallback", Array(Event, Module))
End Sub

Before I fetch the ad in B4XMainPage, I run:

B4X:

Ads.SetCallbackModule(Me, "RewardAd")

Here are the event subs in B4XMainPage.

B4X:

Sub RewardAd_ReceiveAd
    LogColor($"RewardAd_ReceiveAd"$, ColorsExtra.DeepPink)
End Sub

Sub RewardAd_FailedToReceiveAd (ErrorCode As String)
    LogColor($"RewardAd_FailedToReceiveAd ErrorCode=${ErrorCode}"$, ColorsExtra.DeepPink)
End Sub
