My application loads 12 100x100 thumbnail images from the web using
the code below. I then display the thumbnails in a GridView using an
ImageAdapter derived from BaseAdapter. I'm running into memory issues
because each of the thumbnails is held in memory as a Bitmap.
This seems like a fairly straightforward application (display a
gallery of thumbnails from the web), can some give me advice on how to
reduce my memory needs? Maybe there's a better way to display web
images in a GridView that doesn't involve downloading and storing each
one as a Bitmap?
// Download a Bitmap thumbnail for each photo
Bitmap bm;
HttpGet httpRequest;
HttpClient httpclient;
HttpResponse response;
HttpEntity entity;
InputStream instream = null;
BufferedHttpEntity bufHttpEntity;
for (Photo photo : photos) {
try {
httpRequest = new HttpGet(photo.getThumbnail());
httpclient = new DefaultHttpClient();
response = (HttpResponse) httpclient
.execute(httpRequest);
entity = response.getEntity();
bufHttpEntity = new BufferedHttpEntity(
entity);
instream = bufHttpEntity.getContent();
bm = BitmapFactory.decodeStream(instream);
photo.setBm(bm);
listener.onPhotoDownloadListener(photo);
} catch (Exception e) {
} finally {
try {
if (instream != null) {
instream.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
