This class is used to create and insert database

ImageView img;
 String picpath;
 Bitmap bmp;
 Canvas cnvs;
 Random r;
 int x,y,height,width;
 ByteArrayOutputStream blob;
 //SQL sql;
 Paint paint;

 Uri data;
 SQLiteDatabase db;
 String[] filePath={MediaStore.Images.Media.DATA};;
 Cursor cur;
 TextView txt;
 int colIndex;
 ContentValues ctv;
 byte[] imgData;

The code to retrieve data is

public class Login extends Activity {

    User user;
    String name;
    TextView no;
    ImageView img;
    int imgx,imgy;
    View touchlistener;
    SQLiteDatabase db;
    byte[] imgData1;
    Cursor cur;
    int pixelx,pixely;
    public static final String DB_NAME="New.db";
    public static final String TABLE_NAME="Sample";
    public static final int DB_VERSION=1;

    public static final String NAME="Name";
    public static final String NO="No";
    public static final String IMG="Img";
    public static final String PIXELX="PosX";
    public static final String PIXELY="PosY";

    @SuppressLint("NewApi") public void retrieve()
    {
        img=(ImageView)findViewById(R.id.imageView1);

        db=openOrCreateDatabase(DB_NAME,Context.MODE_WORLD_WRITEABLE,null);
        cur=db.query(true,TABLE_NAME,new String[]{NAME,NO,IMG,PIXELX,PIXELY},null,null,null, null,null, null,null);
        cur.moveToFirst();
        imgData1=cur.getBlob(cur.getColumnIndex("Img"));
        img.setImageBitmap(BitmapFactory.decodeByteArray(imgData1, 0,imgData1.length));
        Toast.makeText(getApplicationContext(), "Image Retreived", 100).show();
        cur.close();
        db.close();


    }



    public void onCreate(Bundle savedInstanceState)
    {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.login);
retrieve();
    }

    }
