Hi @ayushi-sk, which version of the SDK are you using?

[ayushi-sk]

Latest 5.1.29 but this seems to be a problem since a long time

I am still getting ANR because of this in latest 5.1.31 version

@ayushi-sk Is there a full stack trace that you can share to show what exactly is blocking the main process?

This strongly suggests that the ANR is caused by heavy or blocking work on the main thread, likely during the class loading or static initialization of IdentityModelStore.

ANR in OneSignal.initWithContext - Service Resolution Blocking Main Thread

Details:

• OneSignal version: 5.1.35
• ANR location: IdentityModelStore. / ServiceRegistrationReflection.resolve
• Impact: App launch delays, Google Play Console ANR reports
• Request: Move service resolution to background thread or provide async init API
