How to Read and Write Barcode on Android in .NET MAUI

Updated: August 2, 2026

.NET MAUI (Multi-platform App UI) is the successor to Xamarin.Forms, enabling developers to build cross-platform applications for Android, iOS, macOS, and Windows using .NET. It streamlines the development process by allowing the creation of native user interfaces that work seamlessly across multiple platforms.

The BarCode.Android package brings barcode support to Android!

IronBarcode Android Package

The BarCode.Android package enables barcode features on Android devices via .NET cross-platform projects. The vanilla BarCode package is not needed.

PM > Install-Package BarCode.Android

Install-Package BarCode.Android

Create a .NET MAUI Project

Open Visual Studio and click on "Create a new project". Search for MAUI, select .NET MAUI App and "Next".

Include the BarCode.Android Library

The library can be added in various ways. The easiest is perhaps by using NuGet.

Inside Visual Studio, right-click on "Dependencies" and select "Manage NuGet Packages ...".
Select the "Browse" tab and search for "BarCode.Android".
Select the "BarCode.Android" package and click on "Install".

To prevent issues with other platforms, modify the csproj file to only include the package when targeting the Android platform. In order to do so:

Right-click on the *.csproj file for your project and select "Edit Project File".

Create a new ItemGroup element as such:

<ItemGroup Condition="$(TargetFramework.Contains('android')) == true">
    <PackageReference Include="BarCode.Android" Version="2025.3.4" />
</ItemGroup>

<ItemGroup Condition="$(TargetFramework.Contains('android')) == true">
    <PackageReference Include="BarCode.Android" Version="2025.3.4" />
</ItemGroup>

XML

Move the "BarCode.Android" PackageReference inside the ItemGroup we just created.

The above steps will prevent the "BarCode.Android" package from being used on platforms such as iOS. For that purpose, install BarCode.iOS instead.

Configure the Android Bundle

For Android to work, you need to configure the Android bundle settings. In your ".csproj" file, add the following entry to specify the configuration file for the Android bundle:

<AndroidBundleConfigurationFile>BundleConfig.json</AndroidBundleConfigurationFile>

<AndroidBundleConfigurationFile>BundleConfig.json</AndroidBundleConfigurationFile>

XML

Create a file named "BundleConfig.json" in the root directory of the project. This JSON file contains the required settings for the Android bundle, which are crucial for the library's functionality.

{
    "optimizations": {
        "uncompress_native_libraries": {}
    }
}

{
    "optimizations": {
        "uncompress_native_libraries": {}
    }
}

JSON

This configuration ensures that native libraries are uncompressed, which is a necessary step for the library to function properly in the Android environment.

Design the App Interface

Update the XAML file to allow users to input values for generating barcodes and QR codes. Additionally, add a button to choose a document for barcode reading. Here's an example:

Read and Write Barcodes

From the MainPage.xaml code above, we can see that the checkbox determines whether the generated barcode and QR code should be in PDF format. Next, we set the license key. Please use either a trial or paid license key for this step.

The code checks and retrieves the value from the barcodeInput variable, then uses the CreateBarcode method to generate the barcode. Finally, it calls the SaveToDownloadsAsync method, which saves the file appropriately for both Android and iOS.

On iOS, a custom file path is required to export the document to the Files application.

Frequently Asked Questions

What is .NET MAUI and how does it relate to barcode scanning on Android?

.NET MAUI, or Multi-platform App UI, is the successor to Xamarin.Forms, allowing developers to build cross-platform applications. The BarCode.Android package integrates with .NET MAUI to enable barcode reading and writing on Android devices.

How do I add the BarCode.Android library to my .NET MAUI project?

You can add the BarCode.Android library using NuGet in Visual Studio. Right-click on 'Dependencies', choose 'Manage NuGet Packages', search for 'BarCode.Android', and click 'Install'.

Can the BarCode.Android package be used for platforms other than Android?

The BarCode.Android package is specifically tailored for Android. For iOS, you need to use the BarCode.iOS package instead.

How can I configure my project to include the BarCode.Android library only for Android?

You should edit your .csproj file to include a conditional ItemGroup for the BarCode.Android package only when targeting Android, using the TargetFramework condition.

Do I need a specific configuration file for using the BarCode.Android library on Android?

Yes, you need to specify the configuration file for the Android bundle in your .csproj file, typically named 'BundleConfig.json', to ensure native libraries are uncompressed.

How can I generate and save a barcode using IronBarcode in a MAUI application?

You can use the BarcodeWriter class to create a barcode from text input, determine the format (PDF or PNG), and then save it using a method like SaveToDownloadsAsync for Android and iOS.

What file formats are supported for saving generated barcodes in IronBarcode?

IronBarcode allows barcodes to be saved in PDF or PNG formats, based on the user's choice in the application.

How does IronBarcode help in processing QR codes in a .NET MAUI Android app?

IronBarcode facilitates QR code creation and reading through the QRCodeWriter class, enabling functionalities like generating QR codes from input text and reading barcode data from files.

Is there a sample project available for getting started with IronBarcode in .NET MAUI?

Yes, you can download a complete .NET MAUI App project with the example code provided in the guide to get started quickly.

What functionalities does IronBarcode provide for reading barcode data from files?

IronBarcode can read barcodes from image and PDF files using the BarcodeReader class, with results formatted and displayed accordingly in the application.
