Perhaps change your code from
while((bytesRead = in.read(buf)) > 0) {
while((bytesRead = in.read(buf)) != -1) {
>From api:
Reads the next byte of data from the input stream. The value byte is
returned as an int in the range 0 to 255. If no byte is available
because the end of the stream has been reached, the value -1 is
returned. This method blocks until input data is available, the end of
the stream is detected, or an exception is thrown.
