I have successfully set up twitter4j and can now post text updates and also upload local media from the device to twitter. But what I really need to do is share remote images from the web - e.g., http://example.com/image.png.
When I execute this code...
StatusUpdate statusUpdate = new StatusUpdate("Hello Twitter");
String imageUrl = "http://example.com/image.png";
File file = new File(imageUrl);
statusUpdate.setMedia(file);
twitter4j.Status status = twitter.updateStatus(statusUpdate);
...it looks like twitter4j tries to treat the url as local because it appears to put a / in front of it, and then throws an exception saying...
/http://example.com/image.png: open failed: ENOENT (No such file or directory)
How to solve? Thanks.
I found there is another setMedia() method that accepts an inputstream as one of it's parameters. This inputstream can be linked to a remote image, like this...
StatusUpdate statusUpdate = new StatusUpdate("Hello Twitter");
String imageUrl = "http://example.com/image.png";
URL url = new URL(imageUrl);
URLConnection urlConnection = url.openConnection();
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
statusUpdate.setMedia("image.png", in);
twitter4j.Status status = twitter.updateStatus(statusUpdate);
//might be a good idea to close the inputstream in a finally block
