Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.codewaves:code-scanner:1.7.6'
	}

	<dependency>
	    <groupId>com.github.codewaves</groupId>
	    <artifactId>code-scanner</artifactId>
	    <version>1.7.6</version>
	</dependency>


                            
    libraryDependencies += "com.github.codewaves" % "code-scanner" % "1.7.6"


                            
    :dependencies [[com.github.codewaves/code-scanner "1.7.6"]]

Usage

Add dependency:

dependencies {
    implementation 'com.budiyev.android:code-scanner:1.7.3'
}

Add camera permission to AndroidManifest.xml (Don't forget about dynamic permissions on API >= 23):

<uses-permission android:name="android.permission.CAMERA"/>

Define a view in your layout file:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.budiyev.android.codescanner.CodeScannerView
        android:id="@+id/scanner_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:frameColor="@android:color/white"
        app:frameCornersSize="50dp"
        app:frameWidth="2dp"
        app:maskColor="#77000000"
        app:squareFrame="true"
        app:autoFocusButtonColor="@android:color/white"
        app:flashButtonColor="@android:color/white"
        app:autoFocusButtonVisible="true"
        app:flashButtonVisible="true"/>
</FrameLayout>

And add following code to your activity:

public class MainActivity extends AppCompatActivity {
    private CodeScanner mCodeScanner;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CodeScannerView scannerView = findViewById(R.id.scanner_view);
        // Use builder
        mCodeScanner = CodeScanner.builder()
                /*camera can be specified by calling .camera(cameraId),
                first back-facing camera on the device by default*/
                /*code formats*/
                .formats(CodeScanner.ALL_FORMATS)/*List<BarcodeFormat>*/
                /*or .formats(BarcodeFormat.QR_CODE, BarcodeFormat.DATA_MATRIX, ...)*/
                /*or .format(BarcodeFormat.QR_CODE) - only one format*/
                /*auto focus*/
                .autoFocus(true).autoFocusMode(AutoFocusMode.SAFE).autoFocusInterval(2000L)
                /*flash*/
                .flash(false)
                /*decode callback*/
                .onDecoded(new DecodeCallback() {
                    @Override
                    public void onDecoded(@NonNull final Result result) {
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                Toast.makeText(MainActivity.this, result.getText(),
                                        Toast.LENGTH_LONG).show();
                            }
                        });
                    }
                })
                /*error callback*/
                .onError(new ErrorCallback() {
                    @Override
                    public void onError(@NonNull final Exception error) {
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                Toast.makeText(MainActivity.this, error.getMessage(),
                                        Toast.LENGTH_LONG).show();
                            }
                        });
                    }
                }).build(this, scannerView);
        // Or use constructor to create scanner with default parameters
        // All parameters can be changed after scanner created
        // mCodeScanner = new CodeScanner(this, scannerView);                
        // mCodeScanner.setDecodeCallback(...);                
        scannerView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mCodeScanner.startPreview();
            }
        });
    }

    @Override
    protected void onResume() {
        super.onResume();
        mCodeScanner.startPreview();
    }

    @Override
    protected void onPause() {
        mCodeScanner.releaseResources();
        super.onPause();
    }
}
