What are the solutions for downloading files on Android?

Question

Java

I want to download files according to the list of URLs, showing the loader, and according to the result, report that so many files with such and such names have been uploaded.
Question: Does anyone have code or library examples that would help solve this issue? Those. during the launch of the application, a Splash activity opens, on which a loader is shown, such as loading data, and then, when it loads, you need to write that everything is OK, the data was received in such and such an amount.

Answer 1

1. Transfer http interaction to service
2. There DefaultHttpClient + in the request add the Range header , this will allow you to receive the file in pieces (if the server supports resuming)

Answer 2

For example, either https://github.com/koush/ion

.load("http://example.com/really-big-file.zip")
.write(new File("/sdcard/really-big-file.zip"))
.setCallback(new FutureCallback<File>() {
   @Override
    public void onCompleted(Exception e, File file) {
        // download done...
        // do stuff with the File or error
    }
});
