Here's the error I'm getting on Android 8 or 9 devices. On newer devices it is working fine.

Fatal Exception: java.lang.NullPointerException: Attempt to read from field 'android.os.MessageQueue android.os.Looper.mQueue' on a null object reference

@murat-mehmet Thanks to report issue for the previous version( < 10) Originally, this lib only going to support Android 10 and later, but take this opportunity to support earlier versions as well.
