I was wondering if there are any apps/(Xposed) modules which can force an image to be seen by the camera.
Basically, I'd like a scanner to scan a self-made barcode rather than needing two phones; one to generate and show the barcode and the other to scan it from a specific app.
Anything that will show an image for the scanner in an app will do.

I'm using ML Kit. I'm trying to achieve the behavior where my barcode scanner Android app keeps trying to focus the camera while I move when trying to find a barcode. You know, the typical "clear-blur" behavior that we get when trying to use our phone camera to take a photo.
What are the settings I should turn on?
I am looking to develop an application that will allow the user to launch the camera and use it to scan what the camera sees for a certain logo or word.
I have had some experience using the Zebra barcode scanning library so I am able to launch the camera and scan for a barcode fine.
The issue comes when I try to scan for a logo. Is it at all possible to scan for the logo in real time with the camera or would I have to have the user take picture and then scan the newly take picture and compare it with the logo that is being searched for?
Scanning for a logo is an entirely different problem. The Zebra Library has been designed specifically to recognized barcodes and qr codes anything outside of that scope and it won't be able to interpret anything. You can scan for logos in real time or on the cloud. Amazon does this with their shopping application so that you can research what you find at the supermarket or at a friends house.
There are companies that can offer you Image Recognition as a Service:

or you can look into your own open source implementation

There's examples for OpenCV for Android but you're going to need a bit of background on Machine Learning and Computer Vision before you get started.
I'm doing black box automation testing (with appium & ruby) for app which use camera in few cases:
- taking photo
- scan QR code
- scan PDF code
I'm looking for a way to set image in to image preview to scan it.
This should(ideally) word for both emulators and real devices.
I was willing to do the same for my app (which scann QR code), and the solution I used was to add an EditText (which appears only in test mode) to put the string, which corresponds to the QR code, and then handling the string as the result of the scan.
The problem with that solution is that you can't test the camera or the functions/methods you made to decode, but it's the only problem so if you are using a library (like ZXing) it's not a big deal, because I assume you want only the string that corresponds with the QR code.
Hello im trying to make my own special custom code scanner. My app's render a special custom barcode and I need to make a very simple scanner that will take whats currently being seen with the camera and quickly process it to decode the barcode. So how can I grab the frames from the camera and use them as images without pressing the "take" button.
check the open source project. It give bar-code without click take photo button.

I am working on a Project which uses the Barcode Scanner for redeem points. I have tried Zxing,QR Droid, Red Laser,Scan Life,Shop Savy etc usig HTC EVO 3D. None of them read all barcodes. But Zbar for IOS reading all the same codes.I think its the problem with hardware of the device.Is there any Scanner App better than above mentioned ?

This barcode is a form of RSS-14. zxing / Barcode Scanner reads it, but it's not the easiest to read. You need to put the image in landscape orientation (right side up). Try TRY_HARDER mode, and restrict your scan to the RSS-14 format to avoid false positives.
