Steps to use Bar Code & QR Code Scanner in your project.

Crate a project(Bar Code & QR Code Scanner Demo) in android studio.

Create a Activity build.gradle and add a dependency to it-

// add dependency to use QR code scanning
compile 'com.journeyapps:zxing-android-embedded:3.4.0'

Now your build.gradle will be like-

apply plugin: 'com.android.application'
android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.pankaj.barcodedemo"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:design:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    // add dependency to use QR code scanning
    compile 'com.journeyapps:zxing-android-embedded:3.4.0'
}

Create a activity MainActivity.Java and update it-

package com.pankaj.barcodedemo;
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;

public class MainActivity extends AppCompatActivity {
    private IntentIntegrator qrScan;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

//      initialize
        qrScan = new IntentIntegrator(this);

        //Specify scanning type like QR/Barcode. Default its scan both type.
//      qrScan.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
        //Add message to show when scannig
        qrScan.setPrompt("Scan a Barcode/QR Code");

        // Use a specific camera of the device
        qrScan.setCameraId(0);

        //enable beep on scan complete
        qrScan.setBeepEnabled(true);
        qrScan.setBarcodeImageEnabled(true);
        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);

        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //open scanner
                qrScan.initiateScan();
            }
        });
    }

    //Getting the scan results
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if (result != null) {

            //if qrcode has nothing in it
            if (result.getContents() == null) {
                Toast.makeText(this, "Result Not Found", Toast.LENGTH_LONG).show();
            } else {
                try {

                    //if qr contains data
                    ((TextView) findViewById(R.id.tvScanData)).setText(result.getContents());
                    Log.e("scan result", result.getContents());
                } catch (Exception e) {
                }
            }
        } else {
            super.onActivityResult(requestCode, resultCode, data);
        }
    }
}

Create a xml activity_main.xml and update it-

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.pankaj.barcodedemo.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />
    </android.support.design.widget.AppBarLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:showIn="@layout/activity_main">
        <TextView
            android:id="@+id/tvScanData"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:autoLink="web"
            android:text="Scan result will show here." />
    </LinearLayout>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        app:srcCompat="@android:drawable/ic_menu_camera" />

</android.support.design.widget.CoordinatorLayout>

If you want to open it in only in one mode like landscape or portrait then add below code to manifest

<activity
    android:name="com.journeyapps.barcodescanner.CaptureActivity"
    android:screenOrientation="portrait"
    tools:replace="screenOrientation" />

All the application development process with Bar Code & QR Code Scanner has completed, Now run the app and look the screen.
Now click on camera button to open scanner.
Now scan the QR or BAR code and see the result.
