ANR when trying to subscribe/unsubscribe from notifications #13

Closed nenahlo closed 5 months ago

nenahlo commented 5 months ago

SDK hangs with ANR when WonderPush.subscribeToNotifications/unsubscribeFromNotifications is called. Reproduced on API level 24 android emulator, 4.4.0 and 4.4.1 version. Works fine on api level 33.

The following commit https://github.com/wonderpush/wonderpush-android-sdk/commit/700be05d91056a72803b94790f49eb1c30f5d9ee may be related to this issue, as the SDK does not hang with version 4.3.4.

Thanks for contacting us through the chat on your WonderPush dashboard. The problem was fixed by properly disabling the SDK auto-init. I'm closing this issue now.
