[javmarina]

I also have a heap dump so tell me if you need it

[samtstern]

@javmarina thanks for this report! We clearly need to do a run through with LeakCanary before the next major release, this is not the first report we've had.

[javmarina]

Thank you so much!
I know these leaks are not terrible issues but it's nice to give help where possible and see how this library gets better every day.

[amandle]

This should be resolved by #334, closing the issue

[javmarina]

Thanks!
