How to reproduce 1:Open the app once, then return to the launcher. 2:Do anything you like without killing(Force Close) the app's process 3:After some time(don't know how much exactly), maybe hours or a day, relaunch the app and probably need open an article, the app will then be crashed several seconds after. 4:Relaunch the app again, it will work fine.

Hi, @kcschan YES, it is a bug. But it won't be fixed anymore. If you are using PaperPlane and the bug troubles you a lot, I suggest you use the official app instead. If you are an Android developer, you could fix it by yourself. It's ok if you create a pr or not. Sorry for that again.

Seems it's solely my misunderstanding here:

https://github.com/TonnyL/PaperPlane/issues/15

Code issues and PRs are welcomed, but you know, apk will not be upgraded and published anymore
