I have a simple function to get an image file from a remote server and
return it as a bitmap, here:
public static Bitmap getRemoteImage(final URL aURL) {
try {
final URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is,
(512*1024));
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte)current);
}
byte[] imageData = baf.toByteArray();
Bitmap bm = BitmapFactory.decodeByteArray(imageData, 0,
imageData.length);
bis.close();
is.close();
// Just to give me a break point after everything else in the
function is done
Bitmap b = bm;
return b;
} catch (Exception e) {
Exception xcp = e;
xcp = null;
}catch(Error e){
Error xcp = e;
xcp = null;
}
return null;
}
Everything in this function executes exactly as you would expect, the
byte array is full with the right amount of data, the decodeByteArray
method returns a Bitmap, both close functions work, and then instead
of returning the bitmap, it simply bails out of the try block and
returns null.
No errors, no warnings, nothing. I've had the issues with OOM errors
before and this is not throwing one. LogCat is not showing an
allocation error as you would expect if it were a memory issue. The
bitmap that is returned has properties that I can see, but not the
correct ones. The bitmap object ("bm") looks like this:
bm Bitmap (id=830063098568)
mDensity 160
mHeight -1
mIsMutable false
mNativeBitmap 1348080
mNinePatchChunk null
mRecycled false
mSrcName null
mWidth -1
The byte array has a length of 73462, so I know it got the image. The
image is a png, but I've tried several different formats. If I could
get an error I would at least know what to fix, but it simply skips
the return statement inside the try block and returns null every
time.
Anyone have any insight?
