Error Accessing external SQLite database

I have an external sqlite database called example.db that I'm trying to a create with OrmLite. I made some searchs on internet and everybody recommended this tutorial http://ift.tt/19PBhQ1

So I followed it and worked well, but when I tried to do the same using OrmLite I couldn't create my own database from external file (example.db). I found out when I call the method createDatabase(), the database is already created and it didn't occur when I was using OpenHelperDatabase without OrmLite.

Does anybody have any idea?

The code is:

//imports

public class DatabaseHelper extends OrmLiteSqliteOpenHelper {

private static String DB_PATH = "/data/data/com.example/databases/";
private static String DB_NAME = "example";
private static final int DATABASE_VERSION = 1;

private SQLiteDatabase exampleDB;
private final Context context;

public DatabaseHelper(Context context) {

    super(context, DB_NAME, null, DATABASE_VERSION);
    this.context = context;
}

public void createDataBase() throws IOException {

    boolean dbExist = checkDataBase();

    if(dbExist){
        Log.i(DatabaseHelper.class.getName(), "Database already exist!!! Here is the problem");
    }else{

        this.getReadableDatabase();

        try {

            copyDataBase();

        } catch (IOException e) {

            throw new Error("Error copying database");

        }
    }

}

private boolean checkDataBase(){

    SQLiteDatabase checkDB = null;

    try{
        String myPath = DB_PATH + DB_NAME;
        checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);

    }catch(SQLiteException e){

        //database does't exist yet.

    }

    if(checkDB != null){

        checkDB.close();

    }

    return checkDB != null ? true : false;
}

private void copyDataBase() throws IOException{

    //Open your local db as the input stream
    InputStream myInput = context.getAssets().open(DB_NAME);

    // Path to the just created empty db
    String outFileName = DB_PATH + DB_NAME;

    //Open the empty db as the output stream
    OutputStream myOutput = new FileOutputStream(outFileName);

    //transfer bytes from the inputfile to the outputfile
    byte[] buffer = new byte[1024];
    int length;
    while ((length = myInput.read(buffer))>0){
        myOutput.write(buffer, 0, length);
    }

    //Close the streams
    myOutput.flush();
    myOutput.close();
    myInput.close();

}

@Override
public void onCreate(SQLiteDatabase db, ConnectionSource connectionSource) {
    Log.i(DatabaseHelper.class.getName(), "onCreate");
    try {
        createDataBase();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

@Override
public void onUpgrade(SQLiteDatabase db, ConnectionSource connectionSource, int oldVersion, int newVersion) {
   //TODO
}


@Override
public synchronized void close() {

    if(exampleDB != null)
        exampleDB.close();

    super.close();

}
}
