    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         messageBox=(TextView)findViewById(R.id.messageBox);
         check();

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }


     public static void updateMessageBox(String msg,String from)
        {
            messageBox.append(msg);
            //Get parent phone number from database
            //check parent number with ...
            if(msg.equals("enable wifi"))
            {
                x="yes";
            }
            //context.startActivity(new Intent(context, MainActivity.class));

Try this, 

Intent intent = getIntent();
finish();
startActivity(intent);

OR

if your application minimum API > 11 then you can call Activity.recreate(); This is preferable if you're in an API11+ environment. You can still check the current version and call the code snippet above if you're in API 10 or below. (Please don't forget to upvote Ralf's answer!)

You can simply use:

finish();
startActivity(getIntent());

to refresh an activity from within itself.
