Java Question Add listener problem (startapp lib)

Douglas Farias · Jul 9, 2020

Hi all.
I'm trying to use the startapp sdk and I'm having some difficulties.

the problem is in adding the interstitial callback

here's the page that talks about it.

Advanced Usage

This section describes advanced usage and personal customization options and is not mandatory for the integration. Interstitial Ads Implement interstitial ads with objects for gaining more control ...

support.startapp.com

here's the initial SDK tutorial, using the .jar file

Start.io

support.startapp.com

and here is an example of a java app.

Here's what I've done so far.

B4X:

Sub Init_StartApp
    
    Private ctxt As JavaObject
    ctxt.InitializeContext
    
    'INIT SDK
    Private StartAppSDK As JavaObject
    StartAppSDK.InitializeStatic("com.startapp.sdk.adsbase.StartAppSDK")
    StartAppSDK.RunMethod("init", Array(ctxt,startAppKey,True))
    
    'SET TEST MODE
    StartAppSDK.RunMethod("setTestAdsEnabled", Array(True))
    
    'INIT ADS
    Private StartAppAd As JavaObject
    StartAppAd.InitializeStatic("com.startapp.sdk.adsbase.StartAppAd")
    
    'INIT LISTENER
    Dim AdListenerIntersticial As Object = StartAppAd.CreateEventFromUI("com.startapp.sdk.adsbase.adlisteners.AdEventListener", "AdListenerIntersticial", Null)
    
    'CALL LOAD AD WITH LISTENER
    StartAppAd.RunMethod("loadAd", Array(AdListenerIntersticial)) 'CRASH HERE
    
    
End Sub

The error log

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 80 (Main)

what can i be doing wrong? as the documentation says I must pass the listener on loadAd

Java:

startAppAd.loadAd (new AdEventListener () {
     @Override
     public void onReceiveAd (Ad ad) {
     }
     @Override
     public void onFailedToReceiveAd (Ad ad) {
     }
});

any help is welcome!
thanks

The problem is here:
StartAppAd.InitializeStatic("com.startapp.sdk.adsbase.StartAppAd")

This doesn't create a new instance, it only references the static class.

Really, i need some coffee .

Working code.

B4X:

    If Not(ctxt.IsInitialized) Then ctxt.InitializeContext
    
    'INIT SDK
    StartAppSDK.InitializeStatic("com.startapp.sdk.adsbase.StartAppSDK")
    StartAppSDK.RunMethod("init", Array(ctxt,startAppKey,True))
    
    'SET TEST MODE
    StartAppSDK.RunMethod("setTestAdsEnabled", Array(True))
    
    'INIT ADS
    StartAppAd.InitializeNewInstance("com.startapp.sdk.adsbase.StartAppAd", Array(ctxt))
    
    'INIT LISTENER
    Dim AdListenerIntersticial As Object = StartAppAd.CreateEventFromUI("com.startapp.sdk.adsbase.adlisteners.AdEventListener", "AdListenerIntersticial", Null)
    
    'CALL LOAD AD WITH LISTENER
    Try
        StartAppAd.RunMethod("loadAd", Array(AdListenerIntersticial))
    Catch
        Log(LastException)
    End Try

thank you!
