feat: Support 16KB page size for Android 15+ #118

JoelOvien · 2025-09-19T10:09:10Z

Description

This PR updates the flutter_pdfview dependency to version 1.4.2-beta.1 to add support for 16KB page sizes on Android 15 and higher.

Problem

With the upcoming changes in Android 15, applications are required to support 16KB page sizes. The native libraries (.so files) included in previous versions of flutter_pdfview were built with a 4KB page size, causing compatibility issues for applications targeting the new Android version.

Solution

This pull request resolves the issue by updating the flutter_pdfview dependency to 1.4.2-beta.1. This version of the dependency includes updated native libraries that are aligned with the 16KB page size requirement.

Code Review

This pull request updates the flutter_pdfview dependency to a beta version to add support for 16KB page sizes on Android 15. The change is straightforward and necessary to ensure compatibility with the upcoming Android version. My feedback includes a suggestion to consider publishing this package as a pre-release version to reflect its dependency on a beta package, which is a good practice for managing user expectations about stability.

Just curious, how are you checking if this package is in alignment? I'm using the script found here, https://developer.android.com/guide/practices/page-sizes#alignment-use-script and running it for my app after making changes to the pubspec, cleaning, getting, and then rebuilding.

The output after doing a dependency override to 1.4.3 for flutter_pdfview shows the following

Actually, I'm guessing this is fine since in the script it states "only arm64-v8a/x86_64 libs need to be aligned". Running the Build APK Analyzer on the release shows all libs in alignment, even the armeabi-v7a. Also, I don't see the 16KB warning when running my app.

Just curious, how are you checking if this package is in alignment? I'm using the script found here, https://developer.android.com/guide/practices/page-sizes#alignment-use-script and running it for my app after making changes to the pubspec, cleaning, getting, and then rebuilding.

The output after doing a dependency override to 1.4.3 for flutter_pdfview shows the following

In my experience. I ran the apk analyzer tool in android studio after updating all packages to their latest resolvable version. The tool said that all my packages are 16kb compatible but, when running the app on a 16kb simulator. I still get the incompatible warning. I manually eliminated packages to see what was the culprit and I concluded that it was the flutter_cached_pdfview -> flutter_pdfview
