@chokokatana do you call OneSignal.setLanguage() in your app?

Do you see this issue if you upgrade to the latest OneSignal-Android-SDK 5.x.x version?

[chokokatana]

• No
• Can't test.

Hi @chokokatana, we haven't seen other reports of this crash and the team is no longer actively supporting and patching the v4 major version of this SDK.

I recommend to upgrade to v5 of our SDK. Please let us know if we can help you with the transition.
