CameraX Library

This Sample uses my custom camerax library where BarCode Analyzer and ImageCapture is used. This project will directly run the application.

Feature Update

Now you can use QRCode/Barcode Scanning via four of the libraries added. You just have to uncomment lines in my library.

1. ZXing
2. ZBar
3. Firebase MLKit Vision
4. Google Vision

Usage

If someone wants to use my camerax library. Follow these steps given below:

1. Add camerax as a library in your project to use it as a library.

2. To use Barcode Scanning:

   a. Add these lines in your activity.xml file

   <com.pb.camerax.BarCodeReaderView
         android:id="@+id/barCodeView"
         android:layout_width="500dp"
         android:layout_height="500dp"
         app:layout_constraintBottom_toBottomOf="parent"
         app:layout_constraintEnd_toEndOf="parent"
         app:layout_constraintStart_toStartOf="parent"
         app:layout_constraintTop_toTopOf="parent" />
   

   b. For using in you activity or fragment:

   i. Initialize the barCodeReaderListener in onCreate()

   barCodeView.barCodeReaderListener = barCodeReaderListener
   

   ii. Init the camera in onCreate

   barCodeView.initCamera(this,null,this,BarCodeCameraConfiguration("FRONT"))
   

   iii. Override the onRequestPermissionsResult method

   override fun onRequestPermissionsResult(requestCode: Int, @NonNull permissions: Array<String?>,grantResults: IntArray) {
         barCodeView.onRequestPermissionsResult(this, permissions, grantResults, requestCode)
   }
   

   iv. Implement the barCodeReaderListener

   private var barCodeReaderListener: BarCodeReaderListener = object : BarCodeReaderListener {
         override fun onSuccess(qrCode: String, status: BarCodeStatus) {
             Toast.makeText(this@BarCodeScannerActivity,"Code : $qrCode",Toast.LENGTH_SHORT).show()
         }
   
         override fun onFailure(status: BarCodeStatus) {
             Log.i(TAG, status.name)
         }
   
         override fun onInitFailure(isAlwaysDenied: Boolean) {
             Toast.makeText(this@BarCodeScannerActivity,"Permission denied always : $isAlwaysDenied",Toast.LENGTH_SHORT).show()
             Log.i(TAG, "$isAlwaysDenied")
         }
   }
   

3. To implement Image Capture:

   a. Add these lines in your activity.xml file

   <com.pb.camerax.ImageCaptureView
         android:id="@+id/barCodeView"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         app:layout_constraintBottom_toBottomOf="parent"
         app:layout_constraintEnd_toEndOf="parent"
         app:layout_constraintStart_toStartOf="parent"
         app:layout_constraintTop_toTopOf="parent" />
   

   b. For using in you activity or fragment:

   i. Initialize the imageCaptureListener in onCreate()

   imageCaptureView.imageCaptureListener = imageCaptureListener
   

   ii. Init the camera in onCreate

   imageCaptureView.initCamera(this,null,this,BarCodeCameraConfiguration("FRONT")) // USE "BACK for Back Camera"
   

   iii. Override the onRequestPermissionsResult method

   override fun onRequestPermissionsResult(requestCode: Int, @NonNull permissions: Array<String?>,grantResults: IntArray) {
         imageCaptureView.onRequestPermissionsResult(this, permissions, grantResults, requestCode)
   }
   

   iv. Implement the imageCaptureListener

   private var imageCaptureListener: ImageCaptureListener = object : ImageCaptureListener {
   
     override fun onCaptureSuccess(path: String, imageCodeStatus: ImageCodeStatus) {
         Log.i(TAG, path)
     }
   
     override fun onInitFailure(isAlwaysDenied: Boolean, imageCodeStatus: ImageCodeStatus) {
         Log.i(TAG, imageCodeStatus.name)
     }
   
     override fun onInitSuccess(imageCodeStatus: ImageCodeStatus) {
         /** This method #captureImage is called after successful initialization. You can use this method on click of a button */
         Handler().postDelayed({
             imageCaptureView.captureImage(this@ImageCaptureActivity)
         }, 5000)
     }
   
     override fun onCaptureFailure(error: String, imageCodeStatus: ImageCodeStatus) {
         Log.i(TAG, error)
     }
   }
