Answer 1

Another way to try would be to use an AsyncTask. This Android article is a good one about threading.

Answer 2

if someone don't understand what context is in @Alex Gitelman answer. write your class name in place of context in which you are writing this handler code like this

Handler h = new Handler(MyClassName.this.getMainLooper());

h.post(new Runnable() {
    @Override
    public void run() {
         Toast.makeText(MyClassName.this,"show toast message",Toast.LENGTH_LONG).show();
    }
});

Answer 3

I am not sure but this looks again like trying to invoke GUI methods on non-GUI threads.

Answer 4

This is how I did it. Of course, you need to pass appropriate context.

   Handler h = new Handler(context.getMainLooper());

    h.post(new Runnable() {
        @Override
        public void run() {
             Toast.makeText(context,message,Toast.LENGTH_LONG).show();
        }
    });
