Could you provide more info? Like the URI that isn't working, can you try a larger amount to see if it's related to #82

Maybe fcdeluxe on Reddit can provide more information, he made a build-off submission. I just added the issue because nobody else had, so it doesn't get lost.

It seems important to fix, demos look terrible without this working :)

Someone else added:

Huawei p20 here. Deep links no longer work with the amount *unless Natrium has been opened first and unlocked. Then deep links successfully fill in the amount field. Natrium is used in every single video which is testament to how brilliant a wallet it is, well done :) hope you squish this bug

[bbedward]

Unable to reproduce with deep links, which are handled exactly the same as URIs read via NFC.

Need some more info with steps on how to reproduce in order to resolve it.

I am fcdeluxe. I own a Oneplus 7t. After the last update of Natrium the amount is no longer automatically filled in. The QR code continues to work perfectly. The problem is limited to read only via NFC. Can I do tests to help you?
This is the string format for setting up NFC. nano_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx?amount=1000000000000000000000000000000

Still a problem and @nanotaa has offered to help

[bbedward]

@nanotaa you are including the scheme for the URI correct? e.g.

nano:nano_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx?amount=1000000000000000000000000000000

If so can you try previous versions from https://github.com/appditto/natrium_wallet_flutter/releases to find the last working version.

The URI is correct.

I have installed version 2.1.8 and it works perfectly. Since version 2.2.1 it does not work. If necessary, I am available for other tests.

Was Natrium open when scanning? I've found that the amount isn't picked up in general if Natrium isn't open when a URI is opened. For example clicking on a link in a browser with nano:nano_xxx&amount=yyy will not autofill the amount if Natrium is closed, but will autofill if Natrium is open in the background. This is of course a different, but related, issue.

e: Reading the previous comments, I'm not sure why @bbedward was unable to reproduce. I can record a video if needed.

Hello @bbedward

I can confirm, in current version amount sometimes shows up, sometimes not when intent triggered by NFC. I can't figure out the way to reproduce it, majority of times (like 80%) the amount doesn't show up, sometimes it does. I am certain the format is correct and the amount is within the wallet's range. When version downgraded to 2.1.8 - it works smoothly 100% times. Did you have a chance to take a look at this? Natrium is awesome and NFC is a killer feature, would be cool to fix it.

Regards

6169e4172704cf5773b6a8031dcff2c1750f7d37 might somewhat solve it, I don't know how to test NFC and haven't received any guidance so reproducing things like this are hard for me.

A possible assumption is that the balance check wasn't working because balance wasnt quite yet loaded at that time or something.

I checked a couple of times on v2.4.3 and it always worked. Thank you!
