Download and install the Android SDK. The installation instructions can be found here:

Download and install the Android NDK. It can be found here:

Build the BDB JDBC libraries.

Enable encryption if required.

By default, encryption is disabled. To enable it, edit <db>/build_android/jdbc/jni/Android.mk and change BDB_ENABLE_ENCRYPTION from false to true.

After enabling encryption, use pragma key to set the password. You must do this before performing any database operations. For example:

 # ./dbsql test.db
dbsql> pragma key="xyzzy";
dbsql> create table t1(x);
dbsql> .quit

# ./dbsql test.db
dbsql> pragma key="xyzzy";
dbsql> .tables
t1 

Enable user authentication if required.

By default, user authentication is disabled. To enable it, edit <db>/build_android/jdbc/jni/Android.mk and change BDB_ENABLE_USERAUTH from false to true. BDB encryption must also be enabled.

For more information, see the "User Authentication" section in Berkeley DB Getting Started with the SQL APIs.

Enable key-store based user authentication if required.

By default, key-store based user authentication is disabled. To enable it, edit <db>/build_android/jdbc/jni/Android.mk and change BDB_ENABLE_USERAUTH_KEYSTORE from false to true. BDB encryption must also be enabled.

For more information, see "Key-store Based User Authentication" section in the Berkeley DB Getting Started with the SQL APIs.

Build the Android NDK:

$ cd <db>/build_android/jdbc/jni
$ <ndk-install-directory>/ndk-build APP_ABI:=<ABI>

This results in the following required files:

If you are using a 6.1.x or lower version of the product, the supported ABI is armeabi. If you are using a 6.2.x or higher version of the product, the supported ABIs are armeabi-v7a and arm64-v8a.

If you are targeting a 64-bit arm platform, you need to change the build_android/db_config.h file to undefine HAVE_MUTEX_ARM_GCC_ASSEMBLY and define HAVE_MUTEX_ARM64_GCC_ASSEMBLY like the following:

/* Define to 1 to use the GCC compiler and ARM64 assembly 
   language mutexes. */
#define HAVE_MUTEX_ARM64_GCC_ASSEMBLY 1

/* Define to 1 to use the GCC compiler and ARM assembly 
   language mutexes. */
/* #undef HAVE_MUTEX_ARM_GCC_ASSEMBLY */
                

Start Eclipse and create an Android project. Use:

This results in an empty code file. Copy and paste the following example code into that file:

package example.testjdbc;

import SQLite.*;
import java.io.*;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import java.sql.*;

public class Test_jdbcActivity extends Activity {

    /*
     * This is the main entrance/body of our sample program. This
     * example illustrates all of the major API usages.
     */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        TextView tv = new TextView(this);
        tv.setText("App Started");
        setContentView(tv);

        System.out.println("Appstart: ");

        String url = 
            "jdbc:sqlite://data/data/example.testjdbc/example.db";
        Connection con;
        String dropString = "drop table if exists COFFEES";
        String createString;
        createString = "create table COFFEES " 
            + "(COF_NAME varchar(32), "
            + "SUP_ID int, " + "PRICE float, " + "SALES int, "
            + "TOTAL int)";
        String insertString = "drop table COFFEES if exisits";
        String query = "select COF_NAME, PRICE from COFFEES";
        Statement stmt;

        try {
            Class.forName("SQLite.JDBCDriver");

        } catch (java.lang.ClassNotFoundException e) {
            System.err.print("ClassNotFoundException: ");
            System.err.println(e.getMessage());
        }

        try {
            con = 
                DriverManager.getConnection(url, "myLogin", "myPW");

            stmt = con.createStatement();
            stmt.executeUpdate(dropString);
            stmt.executeUpdate(createString);
            stmt.close();

            stmt = con.createStatement();
            stmt.executeUpdate("insert into COFFEES "
                + "values('Colombian', 00101, 7.99, 0, 0)");

            stmt.executeUpdate("insert into COFFEES "
                + "values('French_Roast', 00049, 8.99, 0, 0)");

            stmt.executeUpdate("insert into COFFEES "
                + "values('Espresso', 00150, 9.99, 0, 0)");

            stmt.executeUpdate("insert into COFFEES "
                + "values('Colombian_Decaf', 00101, 8.99, 0, 0)");

            stmt.executeUpdate("insert into COFFEES "
                + "values('French_Roast_Decaf', 00049, 9.99, 0, 0)");

            ResultSet rs = stmt.executeQuery(query);

            System.out.println("Coffee Break Coffees and Prices:");
            while (rs.next()) {
                String s = rs.getString("COF_NAME");
                float f = rs.getFloat("PRICE");
                System.out.println(s + "   " + f);
            }
            stmt.close();
            con.close();

        } catch (SQLException ex) {
            System.err.println("SQLException: " + ex.getMessage());
        }
    }
} 

Copy the following files into place:

$ cd <workspace>/test_jdbc
$ mkdir -p libs/armeabi
$ cp -r <db>/build_android/jdbc/libs/armeabi/liboracle-jdbc.so \
libs/armeabi
$ cp -r <db>/build_unix/jdbc/sqlite.jar libs

Back in Eclipse, right click the project name, and select the refresh option to reload the project from the directory. The two new files that were copied into place in the previous step are now included in the project view.

Convert the JAR file to the Android Dalvik format:

Run the project:

Verify your installation. After a short pause (depending on the speed of your system), the application logo is displayed. Use the Android adb command line application to make sure the application is running as expected:

$ cd <android-sdk>/platform-tools
$ ./adb logcat
I/System.out(  539): Appstart: 
I/System.out(  539): Coffee Break Coffees and Prices:
I/System.out(  539): Colombian   7.99
I/System.out(  539): French_Roast   8.99
I/System.out(  539): Espresso   9.99
I/System.out(  539): Colombian_Decaf   8.99
I/System.out(  539): French_Roast_Decaf   9.99

You can also check if the database (example.db) exists in the emulator:

$ ./adb shell ls /data/data/example.testjdbc
example.db
example.db-journal
lib 

Finally, check the database using the BDB SQL shell:

$ ./adb push <db>/build_android/jdbc/libs/armeabi/dbsql \
/data/data/example.testjdbc
326 KB/s (1293760 bytes in 3.865s)
$ ./adb shell
root@android:/ # cd /data/data/example.testjdbc
root@android:/data/data/example.testjdbc # ./dbsql example.db
