+After adding the package, you'll need to [enable extractNativeLibs](https://github.com/sqliteai/sqlite-extensions-guide/blob/18acfc56d6af8791928f3ac8df7dc0e6a9741dd4/examples/android/src/main/AndroidManifest.xml#L6).

+Here's an example of how to use the package:
+```java

+import io.requery.android.database.sqlite.SQLiteDatabase;
+import io.requery.android.database.sqlite.SQLiteDatabaseConfiguration;

+        try {
+            SQLiteCustomExtension vectorExtension = new SQLiteCustomExtension(getApplicationInfo().nativeLibraryDir + "/vector", null);
+            SQLiteDatabaseConfiguration config = new SQLiteDatabaseConfiguration(
+                getCacheDir().getPath() + "/vector_test.db",
+                SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.OPEN_READWRITE,

+                Collections.emptyList(),

+            );
+
+            SQLiteDatabase db = SQLiteDatabase.openDatabase(config, null, null);
+            
+            Cursor cursor = db.rawQuery("SELECT vector_version()", null);
+            if (cursor.moveToFirst()) {
+                String version = cursor.getString(0);
+                resultTextView.setText("vector_version(): " + version);
