Well I am not doing anything fancy - I am using the following code
segment to write
the image to the card - are you doing something similar?
String path =
Environment.getExternalStorageDirectory().toString()
+ "/p2pSOA";
OutputStream outS = null;
File file = new File(path, "IMAGE.jpg");
outS = new FileOutputStream(file);
long sTime = System.currentTimeMillis();
Log.i("p2pSOA","write start at "+sTime);
for (int i=0; i<data.length; i++) {
outS.write(data[i]);
if ( (i%100000) == 0 )
Log.i("p2pSOA","wrote "+i" of
bytes");
}
long eTime = System.currentTimeMillis()-sTime;
Log.i("p2pSOA","write took "+eTime/1000+" secs");
outS.flush();
outS.close();
