Are you looking to harness the power of PDF manipulation in your Android applications? Look no further! In this article, we’ll guide you through the steps to properly set up and use the PdfBox-Android library, ensuring you have all the tools necessary to manage PDF files on your Android device.

What is PdfBox-Android?

PdfBox-Android is a port of the Apache PdfBox library specifically designed for Android. It allows developers to create, manipulate, and read PDF files with ease. Most features of the original library are implemented, and developers can submit feature requests via the issue tracker. You can also add stable releases as dependencies from Maven Central.

Setting Up PdfBox-Android

Follow these simple steps to add PdfBox-Android to your Android project:

1. Add PdfBox-Android Dependency

To start using PdfBox-Android, you must first add the required dependency to your project’s build.gradle file.

dependencies {
    implementation 'com.tom-roush:pdfbox-android:2.0.27.0'
}

2. Initialize the Library

Before you can make any calls to the PDFBox library, you need to initialize the resource loader. This can be done by adding the following line in your application’s context:

PDFBoxResourceLoader.init(getApplicationContext());

3. Explore the Sample App

To familiarize yourself with commonly used features, don’t forget to check out the example app located in the sample directory. It includes various examples showcasing how to utilize the library effectively.

Optional Dependencies

PdfBox-Android allows you to incorporate additional features via third-party libraries. These optional libraries are not included by default to keep the library lightweight. To include them, refer to the dependencies section in the sample project’s build.gradle file.

Handling JPX Images

Since Android does not natively support JPX images, you can leverage the JP2Android library to handle these image formats. Since this library is not included with PdfBox-Android by default, if it is absent from your classpath, JPX images will be ignored, and a warning will be logged.

To include JP2Android library:

dependencies {
    implementation 'com.gemalto.jp2:jp2-android:1.0.3'
}

Note that this library is available only in JCenter. Thus, ensure you have added jcenter() to your repository list.

Important Notes

• Currently based on PDFBox v2.0.27
• Requires API 19 or greater for full functionality

Troubleshooting

If you encounter issues while implementing PdfBox-Android, consider the following troubleshooting steps:

• Ensure you’ve added the correct dependency in your build.gradle file.
• Check if the library is initialized properly with the correct application context.
• If using JPX images, confirm that the JP2Android library is included in your dependencies.
• Make sure that your project is compatible with the required API level.
