Warning: This feature is not supported on camera without autofocus

[YudizAndroidHardik]

Description

I am following your repo and running the code of BlinkId-ImagesSample.

When I click on Scan Document, it shows a warning as mentioned above.

As a Recogniser, I am using BlinkIdSingleSideRecognizer. when I call requiresAutofocus(), it will return true. means this is a mandatory thing

So Is there any way to prevent this issue?

Environment Details

BlinkID version: V6.1.1

Device model: Samsung Galaxy Tab A

Device Android version: 9

Device ABI (processor architecture, e.g. ARMv7):

Hello @YudizAndroidHardik. You can only check if the end user has a device with autofocus. If the camera is without the autofocus, you will get the described alert. Having a device that has a camera with autofocus is one of our requirements. Please let us know if we can be of any additional help. Best.

Thank you for your response

Can we do it without autofocus?

Hello @YudizAndroidHardik. A camera with autofocus is required. If there is anything else that we can assist you with, please let us know. Best.

Hello @YudizAndroidHardik. The only alternative that we can suggest is direct API. More precisely, that the end user directly uploads the image from the gallery to the SDK for processing.

More you can find on this link and here you can find the link for the sample.

Hope this info helps. Please let us know in case of any additional questions.

Hi, I'm commenting this thread because it's kind of related. I'm trying to test your framework on an android tv with an usb camera attached to it. Everything works as expected, if I programmatically check for autofocus

if(pm.hasSystemFeature(PackageManager.FEATURE_CAMERA) && pm.hasSystemFeature(PackageManager.FEATURE_CAMERA_AUTOFOCUS)){
            // True 
        }

it returns true meaning that the autofocus works (it's a Logitech C930e), if I use the camera app I can see the camera autofocusing.

The blinkid app crashes though:

com.microblink.blinkid.hardware.camera.AutoFocusRequiredButNotSupportedException: Autofocus is required, but not supported on this camera

what kind of strategies do you check to see if autofocus really works?

Hello @albert0m and thank you for waiting for our reply.

Setups with external cameras are currently not supported. Our camera management supports only the device's internal cameras. We can suggest that you use direct API, where the end user directly uploads the image from the gallery to the SDK for processing. More you can find on this link and here you can find the link for the sample.

Hope this info was helpful. For any other questions, feel free to contact us.
