Ok, I'm possibly a step closer to the solution:
(thanks to this post:
http://groups.google.com/group/android-developers/browse_thread/thread/d6f8b55cf7b5bc6
)
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
