No b4a bridge. You must be connected USB only. If you cannot connect to the device via USB, you cannot do it.:
'Tools', then 'Videocapture.

  1. Connect your Device to PC via USB
  2. Turn on USB Debugging from Developer option.
  3. Allow if any popup comes up.
  4. B4A > Tools > Clean Project.
  5. Run your program (F5)
  6. When your app starts
  7. B4A > Debug > Video Capture

I do not have this choice on my samsung: Turn on USB Debugging from Developer option.

I managed to activate the developer function on my samsung

(In Android 4.2 and higher versions, the Developer Options menu and USB Debugging option have been hidden. In former 4.X versions of Android, USB Debugging option is under Developer Options menu.)

Thank you all

Double check to make sure that the USB DEBUGGING is on.

Next, on the Log tab, click on connect, if the log displayed succesful connection, then you are good to go.

if still it says cannot connect, Goto the IDE under tools, click on RESTART ADB SERVER. Wait for some few seconds and connect again.

If your device and USB both are working fine then the device should show a notification: USB Debugging Connected.

If that is not there then:
  1. Check using another USB
  2. Reboot your device because sometimes it goes offline.
  3. Check if USB debugging is on.
  4. Some devices have two USB debugging option check and turn that on if it is there.
  5. And as @mcqueccu said Restart ADB server.

Is there any USB Debugging Connected notification on your device when you connect your device via USB?

What happens when you connect your device via USB, then go into the Log tab in B4A & click on the "Connect" button?

If you are getting the same error & running Windows 10, I have had issues previously where Windows updates have installed drivers that won't work with some of my Android devices. If you connect your device via USB, then go into Windows Device Manager & either you're not seeing your device, or you're seeing a yellow warning for it then you might need to reinstall the correct driver. In my case, I find the "Android Composite ADB Interface" driver works with all my devices.

No - you're clicking on Tools->B4A Bridge->Connect. What happens if you click on the "Connect" button at the bottom of the Logs tab (on the right hand side of the IDE screen)?
