#Setup ##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 materialBarcodeScanner = 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();

materialBarcodeScanner.startScan();

  
}

Hook it up to a button

  fab.setOnClickListener(new View.OnClickListener() {

 @Override

 public void onClick(View view) {

  startScan();

 
}

}
);

##3. Start scanning!

#Additional Setup

##Center tracking mode

By default a barcode is tracked/highlighted at the location at which it was found.
With center tracking mode a square image will be shown during scanning that will turn green when a barcode is found. Please note that you can still scan a barcode outside the center tracker! This is purely a visual change.

To activate center tracking mode simply call the following builder method:

.withCenterTracker()

If you want to provide your own image for the tracker you can use:

.withCenterTracker(R.drawable.your_tracker_image, R.drawable.your_detected_state_tracker_image):

##Exclusive barcode scanning

In some situations you might want to scan for only a certain type of barcode like QR-Codes or 2D barcodes. You can do this with the following builder methods:

.withOnlyQRCodeScanning() .withOnly3DScanning() .withOnly2DScanning()

If you want to scan for a very specific combination of barcodes you can setup the builder like this:

.withBarcodeFormats(Barcode.AZTEC | Barcode.EAN_13 | Barcode.CODE_93)

EffortlessPermissions

An Android permission library extending Google's EasyPermissions with convenient additions.

Why EffortlessPermissions?

Used as a drop-in replacement for Google's EasyPermissions and based on its battle-tested implementation.
Added an @AfterPermissionDenied annotation for methods to run automatically after denial.
Included consumer ProGuard rules which fixes your release build.
Added more method overloads which make coding easier.
Added another DialogFragment to open app detail settings which you have more control upon, e.g. dialog title can be hidden now.

In a word, just start with EffortlessPermissions instead of EasyPermissions.
