tips for reading the bar tails from a DJI drone? I know it is supported by the camera. Is there any library that allows you to do it? tips?

You can use Google Vision api to detect barcodes. The picture source is not important: https://www.b4x.com/android/forum/t...on-google-play-services-vision.89705/#content

Hi Erel
the example works very well with smartphones. I tried the example with the DJI 4 Pro-Plus drone (which has the integrated device), but did not see the camera.
Do I have to integrate the demo app of the drone with this example?

thank you

You need to start with the drone example.

You can use JavaObject to get a bitmap from the view returned from Camera.CreateVideoView.

Dim jo As JavaObject = View
jo.RunMethod("getBitmap", Array(MutableBitmap))

MutableBitmap is a bitmap you created with Bitmap.InitializeMutable.
