    I am trying Unity Mediation, and added some ad modules under it.
    Among those ad modules, I have been facing issue in Applovin module.
    I develop Android app only and use Rewarded Ad only. I have installed Applovin connector from Unity Editor (by clicking the button)

    After several days of implementation, I have noticed that the fill rate of Applovin module has been 0%. Also I have found that when an Applovin ad is going to shown, the app crashes, with following error messages.

    ---
    Caused by java.lang.AbstractMethodError
    abstract method "void com.google.android.exoplayer2.Player$Listener.onEvents(com.google.android.exoplayer2.Player, com.google.android.exoplayer2.Player$Events)"
    ---

    I do not know what this really is, but seeing some online forums, it seems the discrepancy of the version of something called "exoplayer" or some declaration on "gradle" is needed (this I do not know or I do not want to know since manual management of gradle may cause unexpected problems now or in the future)

    How this can be solved?

    Hi @astttt,
    Without more information it is hard to give a full solution. If you could give us a full android log we can take a look :)

    Thank you for response. Some other messages I got as as below.

    When I disable Applovin on waterfall lines, the error stops, and enable again, the flow of crashes comes again.

    I'm experiecing same issue after updating IronSource SDK (7.2.3.1) with AppLovin mediation adapter (4.3.36) - the crashes on Android devices significantly increased above bad behavior treshold

    edit:
    @astttt, seems like adding "android.enableDexingArtifactTransform=false" to gradle.properties should fix these crashes

    We are having exactly the same issue using AdMob with AppLovin mediation (SDK version 11.4.4). We also have lots of Android logs if you need more data

    Hi folks, we've identified the issue to be a conflict with dependency resolution for the version of the play-services-basement (in this case, major version update between 17.x and 18.x) package used by the AppLovin sdk. We will be rolling out an update in our 1.0.0 release that allows for more flexibility of the play-services-basement module version between our sdk, applovin, and additional 3rd party sdks and will maintain this in future patches.

    Expect the update soon (the next couple of weeks)!

    Hi all, quick update, we've released a Unity Mediation SDK patch (0.5.1) to tackle the above issue. Let us know if things have improved! If not, we can give this another round of investigation.

    wisesm1, it still happens after updating Unity Mediation SDK to patch (0.5.1). But Mikely9 advice helped, now AppLovin ads plays correctly

    Hello, we are currently using ironSource 7.2.4 (lastest version), combined with Unity Ads (4.3.27.1) and AppLoving (4.3.38.1), which are also the latest version as well. The build was 2020.3.34f1

    We are facing a similar issue on at least 2 Android models: Samsung S7 (Android 8) and Samsung A11 (Android 11). The app crash when it attempts to play ad. The log was very similar to the OP's

    2022-08-20 22:22:12.989 31221-31221/(APP-NAME) E/AndroidRuntime: FATAL EXCEPTION: main
    Process: (APP-NAME), PID: 31221

    (log end)​

    Furthermore, prior to the crash above, we noticed that ironSource could not find appropriate ads when the app starts. The log was:

    2022-08-20 21:56:53.785 22266-22266/[HIDE ON PURPOSE] E/ironSourceSDK: ADAPTER_CALLBACK: AdMobRewardedVideoAdLoadListener onAdFailedToLoad - adapterError = No ads meet eCPM floor. <https://support.google.com/admob/answer/9905175#8>( 3 )

    2022-08-20 21:56:57.241 22266-22266/[HIDE ON PURPOSE] E/ironSourceSDK: ADAPTER_CALLBACK: UnityAdsRewardedVideoListener onUnityAdsFailedToLoad - placementId = [HIDE ON PURPOSE] ironSourceError = errorCode:1058, errorMessage:placement receives no fill
    (log end)​
    As we update ironSource and other packages, this crash affect less devices but still exist!

    Roman3445: Could you kindly elaborate about the exact file to be modified according to Mikely9's advice (gradle.properties)? Unfortunately, I could not find where to edit.

    Thanks for the update in the thread. In the meantime, since it's been noted that adding `android.enableDexingArtifactTransform=false` to the project gradle.properties appears to solve the issue, we will look into why this works and include it in our troubleshooting guide.
