Android Question GooglePlay Console Fails

[Ederson Kerber]

Hi,

I'm getting the below crash in an app on GooglePLay Console:

java.lang.NullPointerException: at com.google.android.gms.common.internal.Preconditions.checkNotNull(com.google.android.gmslay-services-basement@@17.6.0:2)

I'm using FirebaseAdMob2 as shown in the link:
https://www.b4x.com/android/forum/threads/firebaseadmob2-google-mobile-ads-sdk-v20.129609/#content.
All items recommended in SDK Manager are installed. B4A Version 10.70.

Manifest Editor:

CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseAnalytics.FirebaseAnalytics)
CreateResourceFromFile(Macro, FirebaseAdMob.FirebaseAds)

Activity_Create:

Dim m As MobileAds
    Wait For (m.Initialize) MobileAds_Ready
    Dim AdaptiveSize As Map = GetAdaptiveAdSize

    IAd.Initialize("iad", "ca-app-pub-3940256099942544/1033173712")
    IAd.LoadAd

    Activity.LoadLayout("splash")

    If IAd.Ready Then
        IAd.Show
    End If

    Activity.LoadLayout("initial")
End Sub

IAD_AdClosed:

Sub IAD_AdClosed
    Log("Closed")
    IAd.LoadAd 'prepare a new ad
End Sub

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

In the sub iAd_FailedToReceiveAd there is no error in the log.

Thanks for any help!

Hi

Did you add this line in your manifest code?

AddReplacement($ADMOB_APP_ID$, ca-app-pub-6**********~3***********)

 

[Ederson Kerber]

Yes,

AddReplacement($ADMOB_APP_ID$, ca-app-pub-6xxxxxxxxxxxxxxx~1xxxxxxxxx)

It seems that IAD variable wasn't initialized when IAD_Closed was called.

I always put this part of code in Starter service, to make sure that will be always ready:

Dim m As MobileAds
Wait For (m.Initialize) MobileAds_Ready

And IAD must be a Global Variable.

Hi,

IAD is declared as a Global Variable.

There was no such piece of code in Service_Start. I will update the app with this change and see if the error persists.

Thanks @arf programas
