Create a fileDownloadCompleted event and Handling it?
<p>I've got the task to develop a Chat App using Android, things sent between users are Text and Images, when User1 sends User2 an Image File, User2 has to first accept the request, and then file will be sent.</p>

<p>My Problem is, when User2 accepts the File Send Request, I still need to somehow know, that File Download has completed, to view the Image, how can I do that.</p>

<p>Is there an already defined Event in Android or Java, that I can listen to and Handle upon fileDownlaodCompletion? I appreciate help of any kind.</p>
