Current Behaviour

The library is having issues like slowness or even app crash when using MRZ + NFC Scanner

Expected Behaviour

When importing this library on the other projects it should not experience any slowness/delay/lag in reading. As much as possible it will avoid in crash

Steps to Reproduce the Problem

Happens when using NFC and MRZ
Sometimes it will get slow to read. Then suddenly MRZ stops working

Current solution :

Then it requires to stop the app or entire phone
Restart the app every 2 hours

Context

Version: Smartscanner core : v0.4.5 (unrelease version) Capacitor : v0.5.0-beta.9

Run some several tests with a fresh clean ionic project and use Smartscanner capacitor and these are the result with MRZ scanning :

So from this, we can observe that there is no gradually increasing of memory/processor every scan with MRZ.

Profiling with NFC scanner, result no abnormality in Memory/CPU

This issue is related to this one.

I hope someone can fix it.

@ccerdaz are you experiencing this issue? can you give me the version of your google play service?

ccerdaz commented 1 year ago

My Google Play Services?, I honestly had no idea that this was relevant... could you explain why it is?

Anyway, my version is 23.04.13

nicholemnl commented 1 year ago

@ccerdaz sorry yeah i think the google play service version does not affect anything. Thought it might be related from this https://github.com/googlesamples/mlkit/issues/236 but it does not make sense because i got a lower version of google play services compared to yours but i was not able to reproduce this issue:

Tested more than 50 ID scans (MRZ + NFC) for more than 2 hours.
Tried to leave the scanner open for a long time hoping it would break but it did not.
Monitored the memory/cpu profiling and got no abnormality or gradually increasing / spikes during this process.

Though this issue might be related to this https://github.com/newlogic/smartscanner-capacitor/issues/22#issuecomment-1438193571
