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

I'm assuming you are (or should be) using a separate thread to asynchronously accomplish this action.

You need to place the post() in a callback that is called when hostPhoto() is complete.

Generally I've done this with AsyncTask with Android...

This provides you the callback onPostExecute() that you can do your post() inside.
