How to integrate ZXing Library to Android Studio for Barcode Scanning?

Question

I've been looking all over internet how to include zxing library to my project, and I found this tutorial: http://blog.dihaw.com/integrating-zxing-in-your-android-app-as-standalone-scanner/

But when I reach the point that you need to check for BeepManager to add the R import I get all kinds of errors in my project (Even on the MainActivity) that it couldn't find R.

Also I found this one https://github.com/journeyapps/zxing-android-embedded/blob/master/README.md which seemed a lot easier because it was auto integrated by gradle, but when I sync it pops an error that it couldn't find the files.

Any help would be appreciated :) I'm new to Android Studio.

EDIT:

I added the settings of the 2nd method (the one with the gradle settings) to my build.gradle and 4 error pop up:

Error:Failed to find: com.embarkmobile:zxing-android-legacy:2.0.0  Error:Failed to find: com.google.zxing:core:3.0.1  Error:Failed to find: com.embarkmobile:zxing-android-integration:2.0.0  Error:Failed to find: com.embarkmobile:zxing-android-minimal:2.0.0 

Any help?

---ANSWER---

To fix this problem I needed to disable Offline Work on Gradle.

• Android Studio's settings>Gradle>Uncheck 'offline work'

You need add the following to your build.gradle file:

repositories {     mavenCentral()      maven {         url "http://dl.bintray.com/journeyapps/maven"     } }  dependencies {     // Supports Android 4.0.3 and later (API level 15)     compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar'      // Supports Android 2.1 and later (API level 7), but not optimal for later Android versions.     // If you only plan on supporting Android 4.0.3 and up, you don't need to include this.     compile 'com.journeyapps:zxing-android-legacy:2.0.1@aar'      // Convenience library to launch the scanning and encoding Activities.     // It automatically picks the best scanning library from the above two, depending on the     // Android version and what is available.     compile 'com.journeyapps:zxing-android-integration:2.0.1@aar'      // Version 3.0.x of zxing core contains some code that is not compatible on Android 2.2 and earlier.     // This mostly affects encoding, but you should test if you plan to support these versions.     // Older versions e.g. 2.2 may also work if you need support for older Android versions.     compile 'com.google.zxing:core:3.0.1' } 

My build.gradle file like this:

apply plugin: 'com.android.application'  android {     compileSdkVersion 21     buildToolsVersion "21.1.2"      defaultConfig {         applicationId "com.myapplication2"         minSdkVersion 16         targetSdkVersion 21         versionCode 1         versionName "1.0"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  repositories {     mavenCentral()      maven {         url "https://raw.github.com/embarkmobile/zxing-android-minimal/mvn-repo/maven-repository/"     } }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:appcompat-v7:21.0.3'     // Supports Android 4.0.3 and later (API level 15)     compile 'com.embarkmobile:zxing-android-minimal:2.0.0@aar'      // Supports Android 2.1 and later (API level 7), but not optimal for later Android versions.     // If you only plan on supporting Android 4.0.3 and up, you don't need to include this.     compile 'com.embarkmobile:zxing-android-legacy:2.0.0@aar'      // Convenience library to launch the scanning and encoding Activities.     // It automatically picks the best scanning library from the above two, depending on the     // Android version and what is available.     compile 'com.embarkmobile:zxing-android-integration:2.0.0@aar'      // Version 3.0.x of zxing core contains some code that is not compatible on Android 2.2 and earlier.     // This mostly affects encoding, but you should test if you plan to support these versions.     // Older versions e.g. 2.2 may also work if you need support for older Android versions.     compile 'com.google.zxing:core:3.0.1' } 

The code is here.

Also, for how to use it, please refer my answer on the Stackoverflow here

It contains method and also simple code that I have tested.
