androidConfig closes the application #2

Closed mrbreyner closed 3 years ago

mrbreyner commented 3 years ago

hi, i decided to try your plugin and it worked fine, but when i call androidConfig initializer, the application closes instantly, however if i don't use androidConfig, everything works fine.

excuse my English 😁

Thank you for the bug report, I will look into it.

This is the case for me too. Actually, It causes my app to crash after the phone is restarted. It works fine even with androidConfig initialized for the first time the app is run then after the phone is restarted or sometimes when the app is restarted the crash begins.

JulianAssmann commented 3 years ago

Thank you very much for the report. Does it crash with an error message in the console? If so, providing that would be very helpful.

JulianAssmann commented 3 years ago

The issues should now be resolved with this commit, corresponding to version 0.1.2. Please let me know, if this fixes the problem for you.

I just encountered the same problem again with the example app, so I'm reopening this issue.

The error:
