I have an activity which performs an image search, the results (URLs
of thumbnails on the web) are rendered in a GridView.
My GridView adapter class delegates creating the actual Bitmaps to an
AsyncTask that loops to sequentially fetch the image content from each
URL using HTTPClient, and creates the Bitmaps using:
BitmapFactory.decodeStream(entity.getContent()).
I found that the above method sometimes returns "null" silently
instead of creating a Bitmap. The occurrences appear to correlate
with larger stream sizes (I check this by logging
entity.getContentLength()). However, if I put a breakpoint just prior
to the decodeStream call & then resume immediately every time I hit it
(i.e. pause briefly on each iteration), the Bitmaps are created
perfectly every time.
All the images are quite small (most <10K), so the download &
decodeStream happens fairly quickly. There are never more than 10
images processed in one AsyncTask.
Hello !
I'm experiencing exactly the same problem (working every time while
debugging with breakpoints; sometimes failing while normally running),
on Android 1.5
Did you solve this problem ?

I'm having a similar problem where BitmapFactory.decodeStream() is
working reliably in the emulator, but the same app transferred to the
phone is returning null everytime.
Any ideas?
