MaterialBarcodeScanner: Easy to use barcode reader for your Android Project (Uses Google Mobile Vision API).

1. Provide gradle dependency

   compile 'com.edwardvanraak:MaterialBarcodeScanner:0.0.6-ALPHA'

2. Build a MaterialBarcodeScanner

   private void startScan() {
       /**
        * Build a new MaterialBarcodeScanner
        */
       final MaterialBarcodeScanner mBarcodeScanner 
                = new MaterialBarcodeScannerBuilder()
               .withActivity(MainActivity.this)
               .withEnableAutoFocus(true)
               .withBleepEnabled(true)
               .withBackfacingCamera()
               .withText("Scanning...")
               .withResultListener(new MaterialBarcodeScanner.OnResultListener() {
                   @Override
                   public void onResult(Barcode barcode) {
                       barcodeResult = barcode;
                       result.setText(barcode.rawValue);
                   }
               })
               .build();
       mBarcodeScanner.startScan();
   }
   

3. Hook it up to a button

   fab.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {
    startScan();
   }
   });
   

4. Start scanning!
