DownloadId about fetch

[tonyofrancis]

@HassanRaza1112 The reasons why you may be getting an ID of -1 when enqueuing could be the following:

1. Fetch could not enqueue your request because the device ran out of space.
2. Fetch already contains this request. A request with the same downloaded file path already exist and is managed by Fetch. Fetch does not override local files.
3. The file you want to download/enqueue is already located in the directory you wish to save it in.

For the example you provided above, you seem to be creating multiple requests with the same destination file path which is actually a directory and not a unique file. Each new request should have a unique file path.Your request should be similar to the following.

String url = "http://androhub.com/demo/demo.mp4";
String filePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString()
+ "/demo.mp4";

Request request = new Request(url,filePath);
long download id = fetch.enqueue(request);

A great way to generate unique file paths is to add the date or time to the file name/path.

String dateString = new Date().toString();

String filePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString()
+ "/" + dateString + "_demo.mp4";
