java.lang.NoClassDefFoundError: com/appsflyer/r (wrong name: com/appsflyer/R) when running AndroidJUnit

[shoheikawano]

Hi, thank you for providing a useful SDK.

I have integrated AppsFlyer SDK in our Android app, but it turns out that after adding this SDK we encounter build failure when running AndroidJunit with Robolectric test locally, with exception NoClassDefFoundError thrown.

Here is the log:

It would be helpful if you guys can give us feedback of this error if this is something new to you guys or this is something familiar and will be fixed soon.

Thanks!

@shaunkawano did you manage to solve this?

[jbrunton]

Our team is seeing the same. Haven't found a solution. Any chance we could get an update?

[l2dev]

Updating the lib dependency has solved the issue for me.

This is what I have:

implementation 'com.appsflyer:af-android-sdk:4.8.19'

[jbrunton]

Ah, apparently we missed that update. That does seem to work. Thanks, @eurbon!

[shoheikawano]

@eurbon Sorry for the late response.
Updating the library has also solved the issue for us!
Thanks!

Updating the lib dependency has solved the issue for me.

This is what I have:

implementation 'com.appsflyer:af-android-sdk:4.8.19'

I try to upgrade SDK version to 4.9.0 , the issue still has.
