I am writing a code to insert an image from gallery into SQLite and display it in another activity. I am able to insert the image into the database but I am not able to retrieve it. Can you please help me? Thanks in advance This is the code to insert image into database

 public class Register extends Activity {
 ImageView img;
 String picpath;
 Bitmap bmp;
 Canvas cnvs;
 Random r;
 int x,y,height,width;
 ByteArrayOutputStream blob;
 //SQL sql;
 Paint paint;
 String name,no;
 Uri data;
 SQLiteDatabase db;
 String[] filePath={MediaStore.Images.Media.DATA};;
 Cursor cur;
 TextView txt;
 int colIndex;
 ContentValues ctv;
 byte[] imgData;


    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";

 public void create()
    {
     db=openOrCreateDatabase(DB_NAME,Context.MODE_PRIVATE,null);
     db.execSQL("CREATE TABLE IF NOT EXISTS "+TABLE_NAME+"("+IMG+" BLOB );");
     db.close();
    }

 public void insert()
 {
     create();
     db=openOrCreateDatabase(DB_NAME,Context.MODE_WORLD_WRITEABLE,null);
     db.execSQL("DELETE FROM "+TABLE_NAME);
     String s=db.getPath();
    // ctv.put(NAME,"Vignesh");
     //ctv.put(NO,"9578323986");
     try
     {
         FileInputStream img_file=new FileInputStream(picpath);
         BufferedInputStream bis=new BufferedInputStream(img_file);
         imgData=new byte[bis.available()];
         bis.read();
         ctv.put(IMG, imgData);
         long val=db.insert(TABLE_NAME,null, ctv);
         if(val<0){
             Toast.makeText(this.getBaseContext(),"Image not Saved",Toast.LENGTH_SHORT).show();
            }
         else
         {
             txt.append(s);
                txt.append("\n Name "+imgData.length);

             Toast.makeText(this.getBaseContext(),"Image Saved",Toast.LENGTH_SHORT).show();
         }
         bis.close();
     }
     catch(Exception e)
     {
         e.getMessage();
     }

     //ctv.put(PIXELX, x);
     //ctv.put(PIXELY,y);
     db.close();
 }


protected void onCreate(Bundle savedInstanceState)

    super.onCreate(savedInstanceState);
    setContentView(R.layout.register);


    ctv=new ContentValues();
    img=(ImageView)findViewById(R.id.imageView1);
    //sql=new SQL(this);

    Button ok= (Button)findViewById(R.id.button1);

}


public void onActivityResult(int requestCode,int resultCode,Intent intentData)
{
    super.onActivityResult(requestCode, resultCode, intentData);
    if(requestCode==1 && resultCode==RESULT_OK && intentData!=null)
    {

        paint.setColor(Color.RED);

        data=intentData.getData();

        img.setImageBitmap(bmp);
    }   
}   

}

This is the code to retrieve the image

public class Login extends Activity {
//SQL sql;
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()
{

    db=openOrCreateDatabase(DB_NAME,Context.MODE_PRIVATE,null);


    cur=db.query(true,TABLE_NAME,null,null,null,null, null,null, null,null);
    cur.moveToFirst();

    imgData1=cur.getBlob(cur.getColumnIndex("Img"));

    img.setImageBitmap(BitmapFactory.decodeByteArray(imgData1, 0,imgData1.length));

    cur.close();
    db.close();


}



public void onCreate(Bundle savedInstanceState)
{

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


    img=(ImageView)findViewById(R.id.imageView1);



                retrieve();
}

}
