Android ION download with progressbar using FileOutputStream

android, download, fileoutputstream, ion-koush

Solution

You seem to have messed up with the order. Please try this:

Future<FileOutputStream> downloading = Ion.with(getApplicationContext())
    .load("http://example.com/test.txt")
    .progressHandler(new ProgressCallback() { 
        @Override
        public void onProgress(int downloaded, int total) {
            // inform the progress bar of updates in progress
        }
    })
    .write(fos)
    .setCallback(new FutureCallback<FileOutputStream>() {
       @Override
        public void onCompleted(Exception e, FileOutputStream file) {
            // download done...
            // do stuff with the File or error
        }
    });

Problem

I'm trying to modify koush's code from download sample with progressbar, to make it write to a FileOutputStream instead of File, but eclipse give me the following error: The method progressHandler(new ProgressCallback(){}) is undefined for the type ResponseFuture Here is the code: ``` File file = new File(DownloadPath, uri.getLastPathSegment()); FileOutputStream fos = null; try { fos = new FileOutputStream(file); } catch (FileNotFoundException e1) { // TODO Auto-generated catch block } Future<FileOutputStream> downloading = Ion.with(getApplicationContext()) .load(uri) .write(fos) .progressHandler(new ProgressCallback() { @Override public void onProgress(int downloaded, int total) { // inform the progress bar of updates in progress } }) .setCallback(new FutureCallback<FileOutputStream>() { @Override public void onCompleted(Exception e, FileOutputStream file) { // download done... // do stuff with the File or error } }); ```
