Android SQLite support library

This is an Android specific distribution of the latest versions of SQLite. It contains the latest SQLite version and the Android specific database APIs derived from AOSP packaged as an AAR library distributed on jcenter.


  • Consistent
  • Faster
  • Up-to-date

Even the latest version of Android is several versions behind the latest version of SQLite. Theses versions do not have the bug fixes, performance improvements, or new features present in current versions of SQLite. This problem is worse the older the version of the OS the device has. Using this library you can keep up to date with the latest versions of SQLite and provide a consistent version across OS versions and devices.

Use new SQLite features:


This library contains an optimized version of the Android database wrapper API native code that along with newer optimized sqlite versions provide better performance than the current Android database API in generally all cases.

On mid range devices running Android KitKat this library can be up to 40% faster on read operations. Performance varies greatly between different devices and OS versions. On newer OS versions & devices the performance improvement is generally smaller as those versions contain newer SQLite versions.


dependencies {
    implementation 'io.requery:sqlite-android:3.34.1'

Then change usages of android.database.sqlite.SQLiteDatabase to, similarly extend instead of android.database.sqlite.SQLiteOpenHelper. Note similar changes maybe required for classes that depended on android.database.sqlite.SQLiteDatabase equivalent APIs are provided in the package.

If you expose Cursor instances across processes you should wrap the returned cursors in a CrossProcessCursorWrapper for performance reasons the cursors are not cross process by default.

Support library compatibility

The library implements the SupportSQLite interfaces provided by the support library. Use RequerySQLiteOpenHelperFactory to obtain an implementation of (Support)SQLiteOpenHelper based on a SupportSQLiteOpenHelper.Configuration and SupportSQLiteOpenHelper.Callback.

This also allows you to use sqlite-android with libraries like Room by passing an instance of RequerySQLiteOpenHelperFactory to them.

CPU Architectures

The native library is built for the following CPU architectures:

  • armeabi-v7a ~1.4 MB
  • arm64-v8a ~2 MB
  • x86 ~2.1 MB
  • x86_64 ~2.1 MB

However you may not want to include all binaries in your apk. You can exclude certain variants by using packagingOptions:

android {
    packagingOptions {
        exclude 'lib/armeabi-v7a/'
        exclude 'lib/arm64-v8a/'
        exclude 'lib/x86/'
        exclude 'lib/x86_64/'

The size of the artifacts with only the armeabi-v7a binary is ~1.4 MB. In general you can use armeabi-v7a on the majority of Android devices including Intel Atom which provides a native translation layer, however performance under the translation layer is worse than using the x86 binary.

Note that starting August 1, 2019, your apps published on Google Play will need to support 64-bit architectures.


The min SDK level is API level 14 (Ice Cream Sandwich).


The library is versioned after the version of SQLite it contains. For changes specific to just the wrapper API a revision number is added e.g. 3.12.0-X, where X is the revision number.


This project is based on the AOSP code and the Android SQLite bindings No official distributions are made from the Android SQLite bindings it and it has not been updated in a while, this project starts there and makes significant changes:


  • Fast read performance: The original SQLite bindings filled the CursorWindow using it's Java methods from native C++. This was because there is no access to the native CursorWindow native API from the NDK. Unfortunately this slowed read performance significantly (roughly 2x worse vs the android database API) because of extra JNI roundtrips. This has been rewritten without the JNI to Java calls (so more like the original AOSP code) and also using a local memory CursorWindow.
  • Reuse of android.database.sqlite.*, the original SQLite bindings replicated the entire android.database.sqlite API structure including exceptions & interfaces. This project does not do that, instead it reuses the original classes/interfaces when possible in order to simplify migration and/or use with existing code.
  • Unit tests added
  • Compile with clang toolchain
  • Compile with FTS3, FTS4, & JSON1 extension
  • Migrate to gradle build
  • buildscript dynamically fetches and builds the latest sqlite source from
  • Added consumer proguard rules
  • Use support-v4 version of CancellationSignal
  • Fix bug in SQLiteOpenHelper.getDatabaseLocked() wrong path to openOrCreateDatabase
  • Fix removed members in AbstractWindowCursor
  • Made the AOSP code (mostly) warning free but still mergable from source
  • Deprecated classes/methods removed
  • Loadable extension support
