For my current application I collect images from different "event providers" in Spain.
Bitmap bmp=null;
HttpGet httpRequest = new HttpGet(strURL);
long t = System.currentTimeMillis();
HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);
Log.i(TAG, "Image ["+ strURL + "] fetched in [" + (System.currentTimeMillis()-t) + "ms]");
HttpEntity entity = response.getEntity();
InputStream instream = entity.getContent();
bmp = BitmapFactory.decodeStream(instream);
return bmp;
However, when downloading images from salir.com I get the following logcat output:
13970 Gallery_Activity I Fetching image 2/8 URL: http://media.salir.com/_images_/verticales/a/0/1/0/2540-los_inmortales_la_trattoria-marc_aureli_27_29_no.jpg
13970 ServiceHttpRequest I Image [http://media.salir.com/_images_/verticales/a/0/1/0/2540-los_inmortales_la_trattoria-marc_aureli_27_29_no.jpg] fetched in [146ms]
13970 skia D --- decoder->decode returned false
A search for that error message didn't provide much useful results.
Anyone an idea what the problem could be?
Gracias!
Update 1:
After inquiring a bit more and testing different stuff I figured out that the problem seems to lie somewhere else. Even though my logcat output says
13970 ServiceHttpRequest I Image [http://media.salir.com/_images_/verticales/a/0/1/0/2540-los_inmortales_la_trattoria-marc_aureli_27_29_no.jpg] fetched in [146ms]
getContentLength(): 93288
which is the correct length of the image in bytes it seems that there's something wrong with the stream or HTTP connection.
My original code (above) is taking advantage of the ThreadSafeClientConnManager. If I replace it with just a simple URLConnection
it works perfectly:
URL url = new URL(strURL);
URLConnection conn = url.openConnection();
conn.connect();
InputStream instream = conn.getInputStream();
bmp = BitmapFactory.decodeStream(instream);
So, I'm wondering now why does my ThreadSafeClientConnManager
work flawlessly (at least it seems it does) with all my other connections (mostly exchanging JSONObjects
) but not with images from some specific websites (e.g. salir.com - for most other websites it works, though). Is there a HTTP parameter I'm missing?
My current setup is:
HttpParams parameters = new BasicHttpParams();
HttpProtocolParams.setVersion(parameters, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(parameters, HTTP.UTF_8);
HttpProtocolParams.setUseExpectContinue(parameters, false); // some webservers have problems if this is set to true
ConnManagerParams.setMaxTotalConnections(parameters, MAX_TOTAL_CONNECTIONS);
HttpConnectionParams.setConnectionTimeout(parameters, CONNECTION_TIMEOUT);
HttpConnectionParams.setSoTimeout(parameters, SOCKET_TIMEOUT);
SchemeRegistry schReg = new SchemeRegistry();
schReg.register(new Scheme("http",
PlainSocketFactory.getSocketFactory(), HTTP_PORT));
ClientConnectionManager conMgr = new ThreadSafeClientConnManager(parameters,schReg);
DefaultHttpClient http_client = new DefaultHttpClient(conMgr, parameters);
Update 2:
Now, the strange thing is, that it actually does work with the ThreadSafeClientConnManager
-sometimes-. If I keep trying downloading the image and decoding it for a couple of times in a row it might work after 15-30 trials. Very strange.
I hope there's a solution to that since I would prefer using the ThreadSafeClientConnManager
instead of URLConnection
.
Update 3:
As suggest by Mike Mosher below, it seems that by using BufferedHttpEntity the decoding error doesn't appear any more. However now, even though less often than before, I get a SkImageDecoder::Factory returned null
error.
