Android SQLite (libsqlite3.so) Builds for Unity

Prebuilt and reproducible Android native SQLite binaries for Unity projects, including x86_64 support for Magic Leap 2.

Purpose

This repository provides a straightforward way to build and validate libsqlite3.so for Android ABIs commonly used by Unity.

Use this repo when you need to:

  • Include SQLite as a native Android plugin in a Unity project.
  • Ensure 64-bit support (including x86_64) for devices such as Magic Leap 2.
  • Produce consistent libsqlite3.so outputs from the SQLite amalgamation source.

SQLite Version

Current target version: 3.51.3.

What this repository builds

The build process compiles SQLite from the SQL amalgamation ZIP into ABI-specific shared libraries:

  • arm64-v8a/libsqlite3.so
  • armeabi-v7a/libsqlite3.so
  • x86/libsqlite3.so
  • x86_64/libsqlite3.so

(Exact output folders depend on the build script implementation.)

Prerequisites

Before running the build, ensure you have:

  • A Linux environment with standard build tooling.
  • Android NDK/toolchain available for cross-compiling Android shared libraries.
  • Permission to run shell scripts with elevated privileges if needed by your environment.

Build Instructions

From the repository root, run:

sudo bash build.sh

Verify Build Outputs

After a successful build, verify the generated binaries:

file */libsqlite3.so

This should report Android ELF shared objects for each ABI output folder.

Unity Integration Notes

  • Copy each ABI's libsqlite3.so into the corresponding Unity Android plugin ABI folder.
  • In Unity, ensure plugin import settings map each library to the correct Android architecture.
  • Keep ABI coverage aligned with your Player Settings target architectures.
