I have installed the emulator via Android Studio. It runs on my phone but it keeps crashing at random time for example when I click on settings or try connect my phone with a NFC smart card reader

If you use Android Studio to debug the app (or launch in debug mode), then you'll see the actual crash in the debugger. A log would be most helpful.

I have exactly the same issue with the settings.
I have also discovered that the emulator itself crashes because it times out trying to connect to the reader, which is installed on my computer.
I haven't had much time to troubleshoot lately so I will have to come back to that later.

I have not found a solution regarding the settings error

  1. I'm no sure if crash on setting opening and card reading is the same.
  2. my phone is android 9 OP3T LineageOS 16.0

My local build didn't have this problem, but I can reproduce this with the fdroid binaries. Maybe something went wrong during the build/release update.

Until this is fixed, you could try the previous version from F-Droid, which should work in this regard.

As I've already mentioned 2.0 works for me.

I think I've found the problem #167. Unfortunately, I cannot test this right now. Would you mind trying it out?

Could you give me an apk?

Really I meant "2.0 doesn't crash" as in fact it doesn't connect to 35963.
