[android-developers] Re: Image not correctly viewed

[Andrea Bernardi]

Thanks for your answers, but the problem persists.
The code function but the given image "
http://vdt.meteo.alice.it/meteo/imgs/icone/small/previsioni/notte/sereno.png";
is viewed bad, not perfectly as in the browser, the pixel are more big. The
image given from xingye
"http://www.yexing.org/image.axd?picture=browse.png"
is viewed perfectly with my code.
Have you other suggestion?

Andrea

I use a snippet that looks almost identical to yours and it seems to
work fine.  The images I pull are from a Yahoo API, and they vary, but
they all seem to work.  When you say "this don't function" what do you
mean, is there an error in the log, a stacktrace?

This is the snippet I use (which again looks pretty much like what you
have, but works for me):

  try {
URL url = new
URL(report.getCondition().getImageLink());
URLConnection conn = url.openConnection();
conn.connect();
BufferedInputStream bis = new
BufferedInputStream(conn.getInputStream());
Bitmap bm = BitmapFactory.decodeStream(bis);
bis.close();
conditionImage.setImageBitmap(bm);
} catch (IOException e) {
Log.e(Constants.LOGTAG, " " + CLASSTAG, e);
}

conditionImage is just an ImageView.
