PdfiumAndroid - SDK 35 / Android 15 Compatible

This repository is a fork of meganz/PdfiumAndroid, which itself is based on barteksc/PdfiumAndroid.

What's New in This Fork

This fork is updated to SDK 35 / NDK 28 and delivers a working AAR compatible with Android 15 (16KB page size support).

Version 2.0.2 - Significant updates to the build layer and compatibility improvements warrant a major version bump from the original 1.9.0.

Key Updates:

• Android SDK 35 and NDK 28 compatibility
• Android Gradle Plugin 8.9.2 support
• Java 17 requirement (configured via gradle.properties)
• BuildConfig generation fixed for library modules
• Native library packaging corrected in AAR
• 16KB page size support for Android 15
• Windows Git Bash compatible build script
• Updated to PDFium 142.0.7415.0

Requirements

• Java 17+ (required for AGP 8.9.2+)
• Android NDK 28.2.13676358
• Git Bash (for Windows users)
• Ninja build tool - https://github.com/ninja-build/ninja/releases

Building the Library

1. Build Native Libraries

Remark: you might need to update the NDK_ROOT environment variable in the build.sh script to point to your NDK (preferrably v28+)

# Run the build script to compile native libraries
./build.sh

# Optional: Build specific components
./build.sh --build-png --build-freetype

2. Build AAR

Remark: you might need to update the 'javaHome' environment variable in the gradle.properties file to point to your Java 17 installation

# Build debug AAR
./gradlew assembleDebug

# Build release AAR  
./gradlew assembleRelease

# Output: build/outputs/aar/PdfiumAndroid-2.0.2-release.aar

Using in Your Project

Method 1: Local AAR

1. Copy PdfiumAndroid-2.0.2-release.aar to your app's libs/ folder
2. Add to your app's build.gradle:

dependencies {
    implementation files('libs/PdfiumAndroid-2.0.2-release.aar')
    implementation 'androidx.core:core:1.16.0'
}

Method 2: JitPack (if published)

repositories {
    maven { url 'https://jitpack.io' }
}

dependencies {
    implementation 'com.github.yourusername:PdfiumAndroid:v2.0.2'
}

Usage Example

import com.shockwave.pdfium.PdfiumCore;
import com.shockwave.pdfium.PdfDocument;

// Initialize
PdfiumCore pdfiumCore = new PdfiumCore(context);

// Open PDF
PdfDocument pdfDocument = pdfiumCore.newDocument(parcelFileDescriptor);

// Use the library...
