Android Question Cannot find camera

[EvgenyB4A]

I try to launch the project zxScannerLiveView(https://www.b4x.com/android/forum/t...de-scanner-that-is-100-embedded-in-b4a.63764/), but get the following error: "Cannot find any camera on device" on the line: zxslv.startScanner.
The camera is installed and works fine from Android desktop.
What is the problem?

Pls when you paste code or error use this:

Do you tried example by @Johan Schoeman ?
What's your device ?

 

[EvgenyB4A]

I didn't tried.
The device is RK3288 tablet.

Worth testing the camera with CameraEx example.

 

[EvgenyB4A]

I tested and it works with CameraEx.

You should probably try a different barcode library.
