blikoon / qrcodescanner Goto Github PK

hie..

i m sorry but i could not run this code on my phone..
it gives me a notification saying 'Could not open your camera'

i have load qr from file picture but something happened "QR Code could not be scanned"

The GOT_RESULT string in QrCodeActivity which is used as the key for scan result that is passed as extra data with intent has an error.

It should have been com.blikoon.qrcodescanner.got_qr_scan_result instead of com.blikoon.qrcodescanner.got_qr_scan_relult, i.e., result instead of relult.

I can't scan the qr code because the camera in the qr code app is blurry yet the phone's native camera works fine

QRCode scanner is not working. I am using blikoon/QRCodeScanner library

Is there any possibility to toggle the flashlight via code?

Maybe expose a function in QRActivity class that can allow us to toggle the flashlight programmatically instead of clicking in the camera preview? 😅

I've tried to switch on the flashlight using a utility flashlight class before launching the QRActivity (camera preview), however it always turns off the flashlight.

My flashlight util class:

class FlashlightUtil(private val context: Context) {

    fun toggleFlashlight(isOn: Boolean){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            val camManager: CameraManager? = context.getSystemService(Context.CAMERA_SERVICE) as CameraManager?
            var cameraId: String? = null
            try {
                cameraId = camManager?.cameraIdList?.get(0)
                camManager?.setTorchMode(cameraId!!, isOn) 
            } catch (e: CameraAccessException) {
                e.printStackTrace()
            }
        }
    }
}

i am trying to scan QR code to connect hotspot in android 11 but it dosent work

hi
i use compile 'com.github.blikoon:QRCodeScanner:0.1.2' in my project
but android studio couldnt solve this library.

Once i click a button to scan this error occurred front of my screen
Notification: Could not open your camera

Can we use this library to scan bar code

startActivityForResult is deprecated

Loading the picture should scan the QR Code in the picture and update the caller app with info on the ui thread. Make the info readily available on the ui thread so it is usable right away

Problems when turning uri into a path to pass to the decode image method

It writes notification "Could not open your camera"
AFAIK it is common samsung's camera issue, should I describe more?

Im try to integrate with androidx, but after implementation i has a problem where dialog not showing any text. and it is said that reference on null value.

Does this library supports switching between cameras? If yes, then how? If no, are you going to update lib w/ this functionality?

Could not open camera

Can you either remove these prints or enable a way to disable them, its kinda annoying to see in the console.

• The Bug is that while scanning the same QR code image from the Recent Section in Mobile will give the result but if we go from Gallery Section then it will produce the error for the same QR Code.
• I tested with the Android 9 (Pie)

//TODO

How can we change the color of header on the camera screen using this library?

Can we change that?

Please help.

How can I make frame layout green angles a rounded angle. I know I have to write my code inside drawAngle method of QrCodeFinderView. But I can`t figure out how to do it.

Thanks

This will improve easy onboarding

Hi,
I use 2 android phone for this test case.
1st phone use Camera to scan 2nd phone screen QR code (125x125 resolution) from gallery that is using image view to preview it and is fixed size to (125x125 dp) (dp is equivalent to px).
2nd phone scan the QR code (125x125 resolution) from gallery.

Based on this method, they should be having the size of QR code to scan. (Correct me if I'm wrong.)

Result
1st phone always success
2nd phone will fail in some QR Code Picture.

Is there any solution to this?

By default, the QR scanner camera view is zoomed to 2x

cound not open camera

The camera result is upside down.

• Change the color of the angles

• Change the icons

• Change position of texts for better results

i want to add capture image functionality in qecodeactivity class with additional button , can you provide the code for that ... the camera module doesnot seem to have it .

when I run the project it shows cannot open camera

To return to the other activity it stops working
