                    builder.setMessage("Do you want to exit?");
                    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int id) {

                            finish();
                            Intent i=new Intent();
                            i.putExtra("finish", true);
                            i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); // To clean up all activities
                           //startActivity(i);
                            finish();

                        }
                    });

                    builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                    });

                        AlertDialog alert=builder.create();
                    alert.show();


                    break;
