Android Debug Mode: Can't read QR code #170

Open Vanclief opened 5 years ago

Vanclief commented 5 years ago

On android and while on debug mode, qr codes will not be recognized so the onRead function will not be triggered.

What's happening?

Sometimes the package on android debug mode works perfectly, sometimes it does not scan any qr code at all.

How can it be reproduced?

  1. Start react native project (No expo)
  2. Add react-native-qrcode-scanner to a view
  3. Go to https://en.wikipedia.org/wiki/QR_code
  4. Attempt to scan the code

Build details?

OS: Android Package version: 1.1.0

Same to me. It works only the first time I launch the app. I'm using Genymotion.

Vanclief commented 5 years ago

Edit: Clarified it happens on debug mode

NathanDsouza commented 5 years ago

This also happens to be when I'm not on debug mode

Same thing here. Any updates on this?

rey1024 commented 5 years ago

same problem

michal-perlakowski commented 5 years ago

npm i -S react-native-camera@1 fixed this for me.

moaazsidat commented 5 years ago

so needs an update of the dependencies? if so, accepting PRs that fixes it.

@Gothdo this did not solve the issue

michal-perlakowski commented 5 years ago

@Ilario17 Are you sure you installed version 1.x of react-native-camera? The @1 part is important.

Any updates for this one? I have the same problem with RN 0.59.8

try to add reactivateTimeout={300}. Worked for me, although it doesn't make sense

renaldy84 commented 5 years ago

@Nagibaba works for me as well. and yes it doesn't make sense.
