    Toast.makeText(this, "Data Inserted HUP", Toast.LENGTH_LONG).show();
    hupdb.close();*/
    hupdb.openDatabase("data/data/com.example.snit/databases/hup", null, SQLiteDatabase.OPEN_READONLY);
    String s="select * from registration";
    Cursor c=hupdb.rawQuery(s, null);
    String val="";
    if(c!=null)

        {
            do
            {
                    String username=c.getString(1);
