Solución:

 public boolean onKeyDown(int keyCode, KeyEvent event) 
    if (keyCode == KeyEvent.KEYCODE_BACK) 
        exitByBackKey();

        //moveTaskToBack(false);

        return true;
    
    return super.onKeyDown(keyCode, event);


protected void exitByBackKey() 

    AlertDialog alertbox = new AlertDialog.Builder(this)
    .setMessage("Do you want to exit application?")
    .setPositiveButton("Yes", new DialogInterface.OnClickListener() 

        // do something when the button is clicked
        public void onClick(DialogInterface arg0, int arg1) 

            finish();
            //close();


        
    )
    .setNegativeButton("No", new DialogInterface.OnClickListener() 

        // do something when the button is clicked
        public void onClick(DialogInterface arg0, int arg1) 
                       
    )
      .show();

Esta es una solución más simple:

@Override
public void onBackPressed() 
    AlertDialog.Builder builder = new AlertDialog.Builder(this);

    builder.setTitle("Save Or Not");
    builder.setMessage("Do you want to save this? ");
    builder.setPositiveButton("Save", new DialogInterface.OnClickListener() 
        public void onClick(DialogInterface dialog, int id) 
            saveResult();
            MyActivity.super.onBackPressed();
        
    );
    builder.setNegativeButton("Discard", new DialogInterface.OnClickListener() 
        public void onClick(DialogInterface dialog, int id) 
            MyActivity.super.onBackPressed();
        
    );
    builder.show();

 @Override
public void onBackPressed() 
// TODO Auto-generated method stub
      AlertDialog.Builder builder=new AlertDialog.Builder(mContext);
     // builder.setCancelable(false);
      builder.setTitle("Rate Us if u like this");
      builder.setMessage("Do you want to Exit?");
      builder.setPositiveButton("yes",new DialogInterface.OnClickListener() 

        @Override
        public void onClick(DialogInterface dialog, int which) 
            // TODO Auto-generated method stub
            Toast.makeText(mContext, "Yes i wanna exit", Toast.LENGTH_LONG).show();

            finish();
        
    );
      builder.setNegativeButton("No",new DialogInterface.OnClickListener() 

        @Override
        public void onClick(DialogInterface dialog, int which) 
            // TODO Auto-generated method stub
            Toast.makeText(mContext, "i wanna stay on this page", Toast.LENGTH_LONG).show();
            dialog.cancel();

        
    );
      builder.setNeutralButton("Rate",new DialogInterface.OnClickListener() 

        @Override
        public void onClick(DialogInterface dialog, int which) 
            // TODO Auto-generated method stub

            final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
            try 
                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + getPackageName())));
             catch (android.content.ActivityNotFoundException anfe) 
                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + getPackageName())));
            

        
    );
      AlertDialog alert=builder.create();
      alert.show();
     //super.onBackPressed();
