Android Crash - "Callback arg cannot be called more than once";

[mobinni]

Report

Plugin Version

6.15.1

On what Platform are you having the issue?

Android only

What did you do?

We use logEvent

What did you expect to happen?

logEvent callbacks not to crash on Android

What happened instead?

On new arch in production for Android we receive crash logs where onError callback is called, but invoked twice which causes a crash to trigger;

react/nativemodule/core/platform/android/ReactCommon/JavaTurboModule.cpp
      if (!callback) {
          LOG(FATAL) << "Callback arg cannot be called more than once";
          return;
        }

Please provide any other relevant information.

Im not sure how the double invocation happens, based on google play console it happens mostly on backgrounding. I could repro the issue by manually double invoking a callback. Based on the codepaths I see that we trigger the error callback in the try / catch as well as onError, there might be some type of condition being hit here where the error happens in logEvent natively gets thrown up and handled again?

Same with 6.15.3 (expo 52.0.31), we're slowly rolling out a new version and seeing a few of these

[mobinni]

@markstreich we disabled the double callback as a local patch for remediation

[markstreich]

@mobinni could you share the patch?

[markstreich]

Something like this? (I don't know how to recreate it, and don't know java, so kind of flying blind)

@al-af can you please take a look at this

[jbcrestot]

Same with 6.15.3 (expo 52.0.31), we're slowly rolling out a new version and seeing a few of these

The stack trace looks like this

==/base.apk (com.facebook.react.bridge.CxxCallbackImpl.invoke+8)
==/base.apk (com.appsflyer.reactnative.RNAppsFlyerModule$3.onError+12)
==/base.apk (com.appsflyer.internal.AFf1oSDK.getCurrencyIso4217Code+116)
==/base.apk (com.appsflyer.internal.AFe1eSDK.component3+96)

I have the same problem too (with version 6.16.2, expo 52.0.46), I don't understand why in the crash logs there is a reference to this method: getCurrencyIso4217Code when it doesn't exist in the React Native plugin or in the Android SDK.

I have hundreds of crashes in production because of this.

See my crashlytics report

com.appsflyer.reactnative.RNAppsFlyerModule$3.onError + 12

com.appsflyer.internal.AFf1oSDK.getCurrencyIso4217Code + 116

com.appsflyer.internal.AFe1eSDK.component3 + 96

com.appsflyer.internal.AFe1aSDK$4.run + 210

This might be deep inside appsflyer itself - https://github.com/search?q=org%3AAppsFlyerSDK%20getCurrencyIso4217Code&type=code

At least for me, one kind of "solution" to this issue, is to use the non-callback version of the logEvent function, since there are these two signatures for the function:

logEvent(eventName: string, eventValues: object): Promise<string>;
    
logEvent(
      eventName: string,
      eventValues: object,
      successC: SuccessCB,
      errorC: ErrorCB
    ): void;

If I only give the first two parameters to the function, then it uses the version that returns a promise and you can get the result from the promise, and that version of the function doesn't seem to have this issue, probably because it doesn't do callbacks.

I was able to reproduce the issue by disabling the device’s internet connection, opening the app, and performing the action that triggers AppsFlyer’s logEvent multiple times. From my investigation, it seems the library keeps references to old AppsFlyerRequestListener instances internally, so when an error occurs, it invokes those stale listeners again, which eventually causes the crash.

Here is my patch, hope it helps:
