Hello,
I'm having problems with an app that works as it should in the companion. The installed Apk will be closed immediately after being opened. I don't get an error message and I HAVE NO CLUE:
What possible causes could exist here. I know, not a crystal ball.
how would you approach the problem??

Application with customwebview extension not opening in my mobile phone how can I solve this problem...kindly help me...
Sebelum-sebelumnya, ekstensi UrsAI2Mqtt tidak ada masalah ketika digunakan. Hari ini, ekstensi tersebut mengakibatkan aplikasi langsung berhenti dan menutup sendiri ketika aplikasi dijalankan. Saya menyimpulkan demikian, karena pada saat ekstensi tersebut saya hapus dari project, saya coba build dan instal aplikasi tidak ada masalah. Apakah ekstensi tersebut saat ini tidak bisa lagi dipakai di AI2?

Is necessary to update extension libs ?
How can I solve ? (I don't know java development)
Thank you

MIT says the new update has been reversed. Please verify if it works now.

I'm not sure, I guess nb192b is a mid transitioning version from nb195a to nb195c but without the change that crashes the APK.
Actually, nb195b was put out shortly after nb195a to fix a bug. We never got around to publishing release notes for it.
