Answer 1

I have resolved this issue my self by adding

System.loadLibrary("sqliteX");

To each method where they are created

LIKE THIS:

public HashMap<String, ArrayList<String>> word_quiz(String qry) {
    System.loadLibrary("sqliteX");
    ArrayList<String> list1 = new ArrayList<String>();
    ArrayList<String> list2 = new ArrayList<String>();
    SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(DB_PATH+ "/sk1.db", null);
    Cursor mcursor = db.rawQuery(qry, null);
    try {
        mcursor.moveToFirst();
        do {
            list1.add(mcursor.getString(0));
            list2.add(mcursor.getString(1));
        } while (mcursor.moveToNext());

    } catch (IndexOutOfBoundsException e) {
        if (MainActivity.logcat_status) {
            Log.e("Error", e + "");
        }
    }
    mcursor.close();
    mcursor = null;
    HashMap<String, ArrayList<String>> final_list = new HashMap<String, ArrayList<String>>();
    final_list.put("list1", list1);
    final_list.put("list2", list2);
    db.close();
    return final_list;

}

Now its working fine

I think I can also use a constructor to load the library "sqliteX"

Thanks guys for considering my question :)

Answer 2

As opposed to the accepted answer consider inserting the call to the System.loadLibrary function only once, e.g. into the DbHelper.

public class MyDbHelper extends SQLiteOpenHelper {

   static {
      System.loadLibrary("sqliteX");
   }
}

The exception originates from your code at com.example.samplesqlitedb.MainActivity$2.onClick() at com/example/samplesqlitedb/MainActivity.java:56, but System.loadLibrary() is called from org.sqlite.app.customsqlite.CustomSqlite.run_the_tests(). There is no evidence that the org.sqlite.app.customsqlite.CustomSqlite activity was even loaded into JVM when this happened.

I would suggest to load libsqliteX.so from the static constructor of org.sqlite.database.sqlite.SQLiteConnection class. Maybe you can find some better place - e.g. com.example.samplesqlitedb.SearchDataDB class, or the class in your app that extends android.app.Application (if you have such).
