[android-developers] Re: Post Bitmap over Http
You might want to actually compress that JPG by passing a value less than 100.
Try saving the image on your SD card, check what compression gives you
a reasonable size and then set that compression and check w/ the
network code.
Also, you probably won't get that much benefit with buffering the
output because the network is not that fast, unless you're on 3G, so
either set an explicit buffer size or remove the buffering altogether.

[android-developers] Re: Post Bitmap over Http
Hi, I added the following code, however, I got an OutOfMemoryError. It
comes from the bos.flush() line... Am I doing it wrong? I
BufferedOutputStream bos = new BufferedOutputStream(os);
bm.compress(CompressFormat.JPEG, 100, bos);
try {
bos.flush();
bos.close();
os.close();
} catch (IOException e) {
e.printStackTrace();
}
conn.disconnect();
Thank you!

Note that PNG is lossless and will ignore the 2nd argument.
Now, the API *could* have a helper method called save(CompressFormat,
Stream) passing the max quality as a default 2nd parameter but that's
another story...
