Android how to wait for code to finish before continuing

Question

I have a method called hostPhoto(); it basically uploads an image to a site and retrieves a link. I then have an other method to post the link to a website.

Answer 1

You can use AsyncTask here,

AsyncTask

By Using that you can execute the code of

hostPhoto()

in doInBackground() and then execute the code of

post(text+" "+link);

in the onPostExecute() Method, that will the best solution for you.

You can write the code in this pattern

private class MyAsyncTask extends AsyncTask
{
    @Override
    protected Void doInBackground(Void... params) {
        hostPhoto();
        return null;
    }
   @Override
   protected void onPostExecute(Void result) {
        post(text+" "+link);
    }
 }

and the can execute it using

 new MyAsyncTask().execute();
