[Schakalaka]

hello.
I'm going to try to integrate mopub into my app and follow this tutorial by @Pendrush

https://www.b4x.com/android/forum/threads/mopub-ads-library.116307/

I have download the example, create ads on mopub and all should work, but on startup, it returns this error:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **

the last version of mopub android SDK is 5.15.0 (November 18, 2020)


I also looking for an alternative for AdMob to monetize my app, with banner, interstitial, and reward video...

Try to add the two kotlin libraries: https://www.b4x.com/android/forum/t...stom-view-written-with-kotlin.104105/#content

Thank you.
this solves the problem.
Complete solution:
Download the last file version, from here:

https://search.maven.org/artifact/org.jetbrains.kotlin/kotlin-stdlib/1.4.30-M1/jar

and here:

https://repo1.maven.org/maven2/org/jetbrains/kotlin/kotlin-stdlib-jdk8/

Add referance and enable multidex:

    #AdditionalJar: AudienceNetwork.aar
    #AdditionalJar: kotlin-stdlib-1.3.21.jar
    #AdditionalJar: kotlin-stdlib-jdk8-1.3.21.jar
    #MultiDex: True
    'AudienceNetwork.aar is part of Facebook Audience Network Library
    'Download Facebook Audience Network Library from: https://www.b4x.com/android/forum/threads/facebook-audience-network-library.115930/

Don t work with version kotlin-stdlib-1.4.30-M1.jar

useful link:

https://dl.bintray.com/mopub/mopub-android-sdk/

do you know how to add reward videos too?
Do you know a good ad network for banners?
admob - I have a gplay console banned account and this causes the problem with ads
facebook - it allows only apps from play store
tapjpy - as mediation with mopub, don't support banners. mopub, allow the only Facebook

I use mopub, for tapjoy interstitial, (and I'd like to add reward video), but I can't use mopub marketplace ads

can I use AdMob with mediation networks without use real AdMob ads? they can limit ads showing because I haven't a dev play store account
