secscanqr's Issues

custom URL and fetch a lookup page?

This looks like a promising alternative to what we already have in the Fdroid repos. Kudos.

Apart from custom URL as mentioned in ticket #26 , how about the ability to display a page without leaving the app, after loading a custom URL?

This is useful for specific lookup results. It might say for example, that the barcode is not in the database, or that barcode is in the database, and will display additional information.

allow import of VCard from file

A vcard file would be useful because you wouldn't need to type in the text manually

Add feature to change camera orientation

It would be nice to have a feature to choose the scanner orientation from landscape to portrait and vice versa, because the app in portrait and the scanner in landscape mode is awful.

Add option to prevent screenshots

First off, I would like to say thank you for making this great barcode scanning app! I have stopped using ZXing in favour of this open source alternative available on F-Droid.

One of the things I use QR codes for is transferring passwords from my desktop PC to Android. This requires me to put a lot of trust into an Android barcode scanning app... and Android itself.

Android is constantly taking screenshots of everything. These screenshots are saved to storage in PNG format for some reason. These screenshots are used for the recents screen to display a cached image of the app. Once the cached image is no longer used it is deleted but not overwritten, therefore ANY APP can scan the free space to recover the images.

You can use FLAG_SECURE to prevent this (it disables screenshots).

Window flag: treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays.

https://developer.android.com/reference/android/view/Display#FLAG_SECURE

What most app developers do is add a toggle option called "Screen security".

Option to disable scan history

Awesome application! Thanks for that! :)

It would be nice if there was an option to disable the scan history completely, i.e. hiding the tab and not saving scanned codes anywhere.
This would allow for a maximum amount of privacy. Where no data is saved, no data can be compromised.

[Feature Request] New Search Provider Startpage

What do you think of adding Startpage as search provider?

Support zxing intents

Support zxing intents:

text to QR - Intent Source, Scanner Manifest
QR to text - Intent Source, Scanner Manifest

Apps like Syncthing (syncthing/syncthing-android#709) are making use of this API. Adding support to SecScanQR would make it compatible with it, among others.

Feature Request: Helper for Code Generation

It would be nice, if the code generation could not only convert text to a qr-code but also has little forms for the different qr-codes (text, url, email, phone, sms, geo location, vcard, event, wifi config).

auto-copy to clipboard

Hello! Thanks for providing an alternative to the aged Barcode Scanner :-) I'm not sure whether you tried that app, but for me, parting from it is hard for two reasons:

it automatically copies QR content to the clipboard, maybe because it assumes that for most downstream uses, this will help. Have you considered adding this as well? Do you see any risks making this a default?
see #7

[Feature Request]Only ask for storage permission when save Code.

Now when open the generate it will ask for storage permission

Dark theme

Add a black theme for amoled displays please.

Icon / logo design proposal

Hi @Fr4gorSoftware ,
I'm a graphic designer and i'm willing to design an icon and a logo for your application and i need your permission before start .

Thank you.

Set as default for dealing with scan intents

I have both Barcode Scanner from ZXing and SecScanQR (1.1.6 Build 9) installed (from F-Droid). When an external app tries to scan a QR code (e.g. from within Fennec F-Droid browser address bar QR code button or Sleep with Android scan QR code feature), the Barcode Scanner from ZXing starts automatically, without asking which app to choose. I installed another barcode scanner from F-Droid, and tried scanning from an external app. Now, LineageOS asks which app to use, and lists Barcode Scanner and the new one I installed, but not SecScanQR. There is no option in system Settings set for default for neither Barcode Scanner or SecScanQR. If I uninstall Barcode Scanner from ZXing, then system just thinks there is no barcode scanner installed.

Is there any way I can start/call/open SecScanQR from external app as a default code scanner?

Bitcoin donate

Hi i love your app but can u make it possible to donate with Bitcoin?, i don't like to donate with Paypal and i avoid the bigger companies.

Switch camera in settings

Save generated QR-Codes etc.

Feature request : possibility to use the front cam

Hey there !
The back of my phone is in glass and it's broken which means my rear camera is unusable :/
It would be amazing to be able to scan codes again by allowing to swap on the other cam ! Or maybe the idea of scanning from an existing picture would be enough ?

Format gets deleted when screen will be rotated in Version 1.1.6

AGMC Holding is stealing your app

AGMC Holding is offering your app under the name of "WFDP Verification" on the Google Play Store: https://play.google.com/store/apps/details?id=de.t_dankworth.secscanqr

They even use the exact same app name de.t_dankworth.secscanqr as you do.

I noticed this because my alternative Play Store (Yalp Store) tried to download and install an update to version 1.1.8 and fortunately failed due a signature mismatch.

This is a huge deal IMO since nobody knows what kind of malware those guys might have added to the apk.

Can you please confirm that this is an illegitimate copy of your app? I'll gladly assist in reporting them if so.

Feature request: Decode codes from an image

Hi, thanks a lot for your app. It's fast, clean and simply to use, a must have.
The qr reader i used to use had a nice feature to read qr/barcodes from an image (simply share the file to the app), i think it would be a great addiction to your work.
Sorry for my english and thanks for your attention :)

buildToolsVersion '26.0.2' causes reboot on CM11

Launching SecScanQR on my xperiaP with CyanogenMod11 will reboot the phone. Simply installing the app will cause crashes on other background apps/services. This is a problem I already had with other apps and the cause was some incompatibility of the buildToolsVersion with my version of CM. More info here: https://gitlab.com/fdroid/fdroiddata/issues/979

I tried to compile the app with Android Studio and change buildToolVersion and I found that upgrading the buidToolVersion from '26.0.2' to '27.0.3' solves the problem. Android Studio also automatically added some dependencies to gradle.build and other stuff I don't understand (I have zero knowledge in Android development).

For now I'm using the local fixed version but I (and probably also the other few with my specific configuration) will appreciate if the change can be done on the published version. Thank you.

This is the logcat i captured just before the reboot:

Feature idea: "share" action to generate a QR from selected text

Title says it all. What do you think?

Open with custom URL

Add a switch or another button to open codes with a custom URL not just only google search please.

example: https://www.codecheck.info/product.search?q=%s
or: https://de.openfoodfacts.org/cgi/search.pl?search_terms=%s&search_simple=1&action=process

The above examples are from zxing barcode reader where the substitutions are:
%s = content
%f = format
%t = type

Feature wish: clickable link or open in browser button

Can you make the links clickable once scanned or add a open in browser button?
Yes I can paste the link or share it to flashify, but that would be so much quicker 😊
Thanks

Feature Request: Color inversion switch to scan white QR codes printed on a black background

I've come across several QR codes (printed on the back of small devices, like wireless mice) which are printed in white on black. To be able to scam these codes, a colour inversion switch could come in handy (the sort of colour inversion implemented in the Android Accessibility settings).

Feature Request: Dark theme

Hi, I would like to request a dark theme option for the app interface

[Feature Request] Flashlight Button

For some reason my volume buttons are not working on my Samsung Galaxy S6 for turning on the flashlight in the camera mode. But I would perfer a flashlight button in the top-right corner you can tap to turn the flashlight on/off.

BTW: Great App! I been searching a long time for a free, open source, F-Driod QR & barcode scanner and generator app. Thank you so much for this app!

Crash when viewing certain entries in history

When scanning this Data Matrix Code, and subsequently viewing its entry in the history tab, the application crashes.

Download error when downloading via F-Droid app

Tried downloading your app today in F-Droid app with the big INSTALL button. It seems an older version (9) is tried and not available anymore.

This prevents downloading and installing SecScanQR over F-Droid app. So I ended up downloading the latest version (12) from https://f-droid.org/en/packages/de.t_dankworth.secscanqr/

Hide keyboard after QR-Code was generated

Back button not working in SecScanQR

Expected behavior

I launched SecscanQR, Tapped on the 3 dotted icon by the right, then selected settings, tapped scanner so i can set the scanner, then return back to the start page.

Actual behavior

when i clicked on settings, then selected scanner i set what i wanted to set, i pressed the back button by the top it took me back once to the page that says Scanner i tapped the back button again nothing happened i couldn't return back to the start except i quit the app.

How to reproduce

Launch SecScanQR,
click the 3 dotted icon,
click settings,
Tap the back button.

Frequently Asked Question (FAQ) Proposal

Hello there, I'd like to contribute to your awesome project by writing a Frequent Asked Questions for users self-service. Would love to hear from you, thanks.

Can't display image generated

The image file can be saved successfully.

feature request: other 2d codes formats

Hi I would like to ask, out of curiosity, what library are you using to generate/read qr codes? Can you anable other kinds of standards (like data matrix)?

[Request] Read/write VCards, connect to Wifi

At the moment this app does only one thing, reading QR codes. But unless you scanned a link you cannot do much with the result. E.g. after you scanned a VCard you still have to add the contact manually and if you scanned login details to a WIFI network you cannot simply connect to it. The same when you want to create QR codes, you have to add all information manually (e.g. this app doesn't show up in the share menu of contacts).

Are those features planned or is the philosophy of this app to use as less permissions as possible and to renounce such convenience features?

generated QR code is stored with wrong extension .jpg

when generating a QR code and saving it, I got the filename Mon\ Feb\ 04\ 06:56:23\ GMT+01:00\ 2019.jpg but it turns out that the file is in fact PNG (which makes more sense). The extension should match the content. (Version installed: 1.2.0 Build 13)
By the way, many thanks for this useful app!
