ZXing Android Embedded

Barcode scanning library for Android, using ZXing for decoding.

The project is loosely based on the ZXing Android Barcode Scanner application, but is not affiliated with the official ZXing project.


  1. Can be used via Intents (little code required).
  2. Can be embedded in an Activity, for advanced customization of UI and logic.
  3. Scanning can be performed in landscape or portrait mode.
  4. Camera is managed in a background thread, for fast startup time.

A sample application is available in Releases.

By default, Android SDK 24+ is required because of

3.4.0. To support SDK 14+, see Older SDK versions.

Adding aar dependency with Gradle

From version 4.x, only Android SDK 24+ is supported by default, and androidx is required.

Add the following to your

repositories {

dependencies { implementation 'com.journeyapps:zxing-android-embedded:4.2.0' implementation 'androidx.appcompat:appcompat:1.0.2' }

android { buildToolsVersion '28.0.3' // Older versions may give compile errors }

Older SDK versions

For Android SDK versions < 24, you can downgrade

to 3.3.0 or earlier for Android 14+ support:
repositories {

dependencies { implementation('com.journeyapps:zxing-android-embedded:4.2.0') { transitive = false } implementation 'androidx.appcompat:appcompat:1.0.2' implementation '' }

android { buildToolsVersion '28.0.3' }

You'll also need this in your Android manifest:

No guarantees are made on support for older SDK versions - you'll have to test to make sure it's compatible.

Hardware Acceleration

Hardware acceleration is required since TextureView is used.

Make sure it is enabled in your manifest file:


Usage with IntentIntegrator

Launch the intent with the default options: ``

new IntentIntegrator(this).initiateScan(); //
this` is the current Activity

// Get the results: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data); if(result != null) { if(result.getContents() == null) { Toast.makeText(this, "Cancelled", Toast.LENGTHLONG).show(); } else { Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTHLONG).show(); } } else { super.onActivityResult(requestCode, resultCode, data); } } ```

Use from a Fragment: ``

IntentIntegrator.forFragment(this).initiateScan(); //
this` is the current Fragment

// If you're using the support library, use IntentIntegrator.forSupportFragment(this) instead. ```

Customize options:

IntentIntegrator integrator = new IntentIntegrator(this);
integrator.setPrompt("Scan a barcode");
integrator.setCameraId(0);  // Use a specific camera of the device

See IntentIntegrator for more options.

Generate Barcode example

While this is not the primary purpose of this library, it does include basic support for generating some barcode types:

try {
  BarcodeEncoder barcodeEncoder = new BarcodeEncoder();
  Bitmap bitmap = barcodeEncoder.encodeBitmap("content", BarcodeFormat.QR_CODE, 400, 400);
  ImageView imageViewQrCode = (ImageView) findViewById(;
} catch(Exception e) {


No customization of the image is currently supported, including changing colors or padding. If you require more customization, copy and modify the source for the encoder.

Changing the orientation

To change the orientation, specify the orientation in your

and let the
to update the Activity's definition.


IntentIntegrator integrator = new IntentIntegrator(this);

Customization and advanced options


For more advanced options, look at the Sample Application, and browse the source code of the library.

This is considered advanced usage, and is not well-documented or supported.

Android Permissions

The camera permission is required for barcode scanning to function. It is automatically included as part of the library. On Android 6 it is requested at runtime when the barcode scanner is first opened.

When using BarcodeView directly (instead of via IntentIntegrator / CaptureActivity), you have to request the permission manually before calling

, otherwise the camera will fail to open.

Building locally

./gradlew assemble

To deploy the artifacts the your local Maven repository:

./gradlew publishToMavenLocal

You can then use your local version by specifying in your

repositories {
