You cannot allocate a 14MB byte array in memory. Your application has only access to 16MB maximum. To download a large file from the Web, simply read it little bit by little bit. For instance, instead of reading 16MB at once, download 16 or 32kB, write them to the outputstream, and keep looping until the end of the stream.
