Hi,

You can use our KeyMapping feature the remap the enter key to launch the camera app via an intent: https://techdocs.zebra.com/mx/keymappingmgr/

Alternatively you could implement a KeyListener in your application to listen for the enter key, and then trigger the camera app yourself, which may give a bit more control.

Thanks,

James

Hi James,

First of all, thank you for your quick response. Basically when the user presses the enter key, the below code is called:

val cameraIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
cameraIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
cameraIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri)
startActivityForResult(
    cameraIntent,
    REQUEST_CODE_CAMERA
)

At this point the camera is already open. What I would like to achieve is to implement a KeyListener to trigger the button of the camera app which takes a picture (kindly see the image below). Is this possible ?

Thank you in advance,

Chris

Hi Chris,

Apologies, I misread your initial question - thanks for the explanation.

There is no way to trigger the camera capture programmatically w/ the default camera app, as far as I'm aware. There may be some 3rd party apps that include an API for triggering camera capture via, for example, an intent, which could then be mapped to the enter key but I don't have any specific recommendations.

Thanks,

James
