Hi all,
I'm implementing Erel's BARCODE READER into my app and the added feature is running without error.
But when I tap the START button, all I get is a black rectangle with no camera picture. I then tap the button again (STOP) and the rectangle (Panel) disappears as expected.
I put a debug on some of the code to step thru the code, and the camera picture appeared. Hovering over the barcode, the code "captured" the barcode as expected.
Initially, I downloaded the demo app and ran it without error and it ran as expected, with none of the above issues, it works perfectly.
My device (Samsung 23Plus) has 3 back cameras and the code reports 3 cameras in my app and the demo app.
Here are the Log results from my app:
So I need to figure out why the camera picture does not appear while running it.
Any help on this would be appreciated.
BTW... I did copy the #AdditionalJar to the Main and copied in the Manifest additions as well.
UPDATE #1: after running the app in debug mode and stepping thru the code, I see the camera picture starts/appears with the following CameraExClass function:
So now why doesn't the camera picture start without stepping thru the code?
UPDATE #2: added a Sleep(100) as follows and now the camera picture appears as expected and the code reads the barcode as expected.
