[Bug]: App freezes on Android 15+ due to libe_sqlite3.so 4 KB page size (Akavache.Sqlite3)

[leapse]

Describe the bug 🐞

Description
When initializing Akavache in a .NET MAUI app targeting .NET 9, the application hangs on the splash screen on Android 15 (API 34) and newer.

This appears to be related to the native SQLite library included with Akavache (libe_sqlite3.so) still being built with a 4 KB page size, while Android 15+ requires 16 KB page sizes for shared libraries.

Error:
XA0141: Android 16 will require 16 KB page sizes, shared library 'libe_sqlite3.so' does not have a 16 KB page size.

Step to reproduce

1. Create a new .NET MAUI app targeting Android 34+.
2. Add Akavache 11.x and initialize it in App.xaml.cs:

3. Akavache.Registrations.Start("AppName");
   

4. Build and deploy to an Android 15 device or emulator.

5. App hangs on the splash screen.
   

Expected behavior

App should initialize Akavache and load normally.

Actual Behavior
App freezes on startup with out a crash

Potentially this is out of scope of our project given that's SQLite a dependency of ours. They might have a 16kb page size nuget package we aren't including properly or the default isn't.

Thanks so much for the quick reply! That makes sense and I understand that the issue comes from the libe_sqlite3.so library that Akavache depends on via SQLitePCLRaw.

Just to clarify, we already tried updating the SQLite dependency directly by adding the latest
SQLitePCLRaw.bundle_e_sqlite3 (2.1.9), but it seems the build still ends up including the older libe_sqlite3.so version from inside the Akavache dependency itself.

If there’s any way to rebuild Akavache.Sqlite3 or bump its dependency to the newer SQLitePCLRaw (built with 16 KB pages), that should solve the issue.

Thanks for looking into this and for maintaining Akavache. It’s been a great tool for our app.

You are using Akavache 11 and starting it the same way you do Akavache 10? Are you sure you are using 11? Because there were a lot of breaking changes. I have Akavache 11 and do not have this hanging issue?

This is an upstream issue in the SQLitePCLRaw native library (libe_sqlite3.so), not something Akavache can fix directly. The 16KB page alignment requirement for Android 15+ needs to be addressed in the SQLitePCLRaw build pipeline.

Akavache currently uses SQLitePCLRaw 2.1.11 via SQLitePCLRaw.bundle_green. We'll track upstream progress and update the dependency when a version with 16KB-aligned native libraries is available.

Workaround: If you're hitting this issue, you can try:

1. Using a newer version of SQLitePCLRaw.bundle_green if one is released with 16KB support
2. Using the system SQLite on Android instead of the bundled one (though this may have compatibility implications)

We'll keep this issue open to track the upstream fix.
