My app have three process, the AppLovinSdk can initialize in the main process, in other process, it can initialize , but when I use MaxNativeAdLoader to load ad, it throws the NPE.

the sdk I am using:
implementation 'com.applovin:applovin-sdk:11.1.0'
implementation 'com.facebook.android:audience-network-sdk:6.8.0'
implementation 'com.applovin.mediation:facebook-adapter:6.8.0.8'

@NiaNingXue, could you try using this MaxNativeAdLoader constructor and passing in your instance of our SDK from the other process?

MaxNativeAdLoader(final String adUnitId, final AppLovinSdk sdk, final Context context)

Do I need to call the initializeSdk in every process? when I do this, it crash

        if (getPackageName().equals(getCurrentProcessName())) {// main process
            // Initialize the AppLovin SDK
            AppLovinSdk.getInstance( this ).setMediationProvider( AppLovinMediationProvider.MAX );
            AppLovinSdk.getInstance( this ).initializeSdk( config -> {
                Log.i(TAG, "AppLovinSdk initialized");
            } );
        } else if ("com.alpha.demo:one".equals(getCurrentProcessName())) { // another process
            // Initialize the AppLovin SDK
            AppLovinSdk.getInstance(this).setMediationProvider(AppLovinMediationProvider.MAX);
            AppLovinSdk.getInstance(this).initializeSdk(config -> {
                Log.i(TAG, "AppLovinSdk initialized");
            });
        }

@NiaNingXue, you should not have to initialize us in every process. You should be able to pass the SDK instance around. Let us know if there are any issues doing that.

From the stack it shows that you make a activity weakReference, and the weakReference is null?

Hi @NiaNingXue - The crash will be resolved in the next SDK release, I'll notify this thread when that happens. Is there anyway you can pass in an Activity to your MaxNativeAdLoader call?

@thomasmso I think it is better not to pass a activity when loading a ad, because it may lead to memory leak

@thomasmso

We will only hold a WeakReference to it.

I am used to cache the loaded MaxAd, I don`t know if it affects something

@thomasmso Hi, I also test the MaxInterstitialAd in multi process, it will crash too

new MaxInterstitialAd (adId, AppLovinSdk.getInstance(context),context)

Hi, just test the version 11.1.1 and the MaxNativeAdLoader now works. but MaxInterstitialAd still has a problem. MaxInterstitialAd can load , but when I call showAd(), it only show a black screen, please confirm @thomasmso

Can you send over a video recording of the issue, and our SDK's verbose logs?

@NiaNingXue

Do you have an email for receiving video?

@pavelupward
Copy link

@NiaNingXue just curious) what is your use case? Am I right, that in case AppLovin crash, you main app still working?

@chauduyphanvu
Copy link

@NiaNingXue, one way to determine if that is related to the multi-process use case you were trying to achieve is to request that ad from our sample app and see if you get a similar issue (black screen). This is because such issues tend to be due to specific ads and not necessarily because of your architecture.

Another way is to check how consistently you get that issue. If you always get a black screen in your multi-process architecture and never get it otherwise, then it can help us narrow down on the causes. Thank you.

Thanks @chauduyphanvu , I am sure it is because of the multi-process. I fix it by adding the "multiprocess="true""

        <activity
            android:name="com.applovin.adview.AppLovinFullscreenActivity"
            android:configChanges="keyboard|keyboardHidden|locale|orientation|screenLayout|screenSize|smallestScreenSize|uiMode"
            android:exported="false"
            android:hardwareAccelerated="true"
            android:launchMode="singleTop"
            android:multiprocess="true"
            android:screenOrientation="behind" />
