+# SQLCipher for Android
+
+SQLCipher for Android provides a library replacement for `android.database.sqlite` on the Android platform for use on [SQLCipher](https://github.com/sqlcipher/sqlcipher) databases. This library is based on the upstream Android Bindings project and aims to be a long-term replacement for the original [SQLCipher for Android](https://github.com/sqlcipher/android-database-sqlcipher) library.
+
+### Compatibility
+
+SQLCipher for Android supports Android API 16 and up on `armeabi-v7a`, `x86`, `x86_64`, and `arm64_v8a` architectures.
+
+### Contributions
+
+We welcome contributions, to contribute to SQLCipher for Android, a [contributor agreement](https://www.zetetic.net/contributions/) needs to be submitted. All submissions should be based on the `master` branch.
+
+
+### Application Integration
+
+
+```
+import net.zetetic.database.sqlcipher.SQLiteDatabase;
+
+System.loadLibrary("sqlcipher");
+SQLiteDatabase database = SQLiteDatabase.openOrCreateDatabase(databaseFile, password, null, null, null);
+```
+
+### Pre/Post Key Operations
+
+To perform operations on the database instance immediately before or after the keying operation is performed, provide a `SQLiteDatabaseHook` instance when creating your database connection:
+
+```
+SQLiteDatabaseHook hook = new SQLiteDatabaseHook() {
+      public void preKey(SQLiteConnection connection) { }
+      public void postKey(SQLiteConnection connection) { }
+    };
+```
+
+### Building 
+
+This repository is not batteries-included. Specificially, you will need to build `libcrypto.so`, the shared library from OpenSSL using the NDK for the [supported platforms](#compatibility), and bundle the top-level `include` folder from OpenSSL. Additionally, you will need to build a SQLCipher amalgamation. These files will need to be placed in the following locations:
+
+```
+<project-root>/sqlcipher/src/main/jni/sqlcipher/android-libs/armeabi-v7a/libcrypto.so
+<project-root>/sqlcipher/src/main/jni/sqlcipher/android-libs/x86/libcrypto.so
+<project-root>/sqlcipher/src/main/jni/sqlcipher/android-libs/x86_64/libcrypto.so
+<project-root>/sqlcipher/src/main/jni/sqlcipher/android-libs/arm64_v8a/libcrypto.so
+<project-root>/sqlcipher/src/main/jni/sqlcipher/android-libs/include/
+<project-root>/sqlcipher/src/main/jni/sqlcipher/sqlite3.c
+<project-root>/sqlcipher/src/main/jni/sqlcipher/sqlite3.h
+```
+
+To build the AAR package, either build directly within Android Studio, or from the command line:
+
+```
+./gradlew assembleRelease
+```
+
