Hi So, the solution was to extract the filename from setDownloadListener() and to manage the download with an AsyncTask using an HttpUrlConnection.
8< - - - - - - - [from the AsyncTask doInBackground() method] ... // Store call parameters URL url = new URL(params.source_url); String target_file_path = params.destination_file_path; // Open the URL HttpURLConnection uconn = (HttpURLConnection)url.openConnection(); uconn.setConnectTimeout(20000); uconn.setReadTimeout(10000); uconn.setDoInput(true); uconn.connect(); // used later to update a 0-100% progress bar int lenghtOfFile = uconn.getContentLength(); // downlod the file BufferedInputStream input = new BufferedInputStream(url.openStream(), 8192); OutputStream os = new FileOutputStream(target_file_path); BufferedOutputStream output = new BufferedOutputStream(os, 8192); ... 8< - - - - - - - best :) -- Mathieu On Sep 30, 2:31 pm, bdk <[email protected]> wrote: > Ok, I'm possibly a step closer to the solution: > > (thanks to this > post:http://groups.google.com/group/android-developers/browse_thread/threa... > ) > > mWebView.setDownloadListener(new DownloadListener() > { > public void onDownloadStart(String url, String userAgent, > String contentDisposition, String mimetype, > long contentLength) > { > Log.i("OF", "onDownloadStart(): " + " url = " + url ); > Log.i("OF", " userAgent = " + userAgent ); > Log.i("OF", " contentDisposition = " + contentDisposition ); > Log.i("OF", " mimetype = " + mimetype ); > Log.i("OF", " contentLength (KB) = " + (contentLength / > 1024.0) ); > } > > }); > > from this one I can retrieve an easier to parse > "contentDisposition" (no cryptic symbols/encodings) > > now the question is: how do I move on to starting a custom download? > I'll show a progress-bar and the file will be downloaded to > apredefined folder. > > Is there any other higher level function available or shall I base the > download code on HTTP Get? > > thanks > > -- > Mathieu > > On Sep 30, 1:21 pm,bdk<[email protected]> wrote: > > > > > > > > > Hi > > > I'm in the following situation: I'm using a WebView in an application > > to allow the download of files stored in a phpBB forum. > > I need to directly handle the downloads, saving the files to the > > application folders with their original names. > > > I'm bound to Android 2.2 Froyo, so no DownloadManager (if it even > > helps:http://www.vogella.de/blog/2011/06/14/android-downloadmanager-example/ > > ). > > > So, the problem is that the download links for the files are like > > this: > > > http://mywebsite.com/download/file.php?id=123 > > > These links get caught by shouldOverrideUrlLoading(), but I can't > > handle the download in a custom way since there's no actual "file path > > and name on the server". > > > I tried to use an HttpURLConnection and checked the returned headers. > > I located the file name in the "Content-disposition" header value, > > which is something like: > > > attachment; filename*=UTF-8''the%20file%20name%20on%20the%20server.aaa > > > Seems like phpBB generates this HTML response header here: > > https://github.com/phpbb/phpbb3/blob/develop/phpBB/download/file.php#... > > which refers to: > > https://github.com/phpbb/phpbb3/blob/develop/phpBB/includes/functions... > > more > > specificallyhttps://github.com/phpbb/phpbb3/blob/develop/phpBB/includes/functions... > > > So, WebView alone does not seem able to handle this kind of "Content- > > disposition" HTTP response header. > > > It must be noted that these phpBB "file.php?id=123" links do work in > > the BrowserActivity that comes with each Android OS, and the correct > > file name pops up in the "save as..." dialog. > > > ATM I'm digging in BrowserActivity.java present in Android's > > sourcecode repository... > > > I saw that I might be good to go by using the InputStream returned by > > an HttpURLConnection, as in e.g.: > > > http://getablogger.blogspot.com/2008/01/android-download-image-from-s... > > http://www.helloandroid.com/tutorials/how-download-fileimage-url-your... > > > In the case that this is the only solution a question remains: how do > > I retrieve the original filename? > > Parsing the "Content-disposition" header value? :S > > > any hint is appreciated! > > thanks > > > -- > > Mathieu -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
