InputStream – Dealing with network changes-Collection of common programming errors
I’m downloading an attachment using Java mail API and whenever there is a small change in network state, my app gets stuck and I have to restart it, it’s not even crashing. This is the code snippet:
InputStream is = bodyPart.getInputStream();
String fileName = MimeUtility.decodeText(bodyPart.getFileName());
// Downloading the file
File f = new File(Constants.getPath() + fileName);
try {
FileOutputStream fos;
fos = new FileOutputStream(f);
byte[] buf = new byte[8*1024];
int bytesRead;
while ((bytesRead = is.read(buf)) != -1) {
fos.write(buf, 0, bytesRead);
}
fos.close();
}
What is the best way to deal with this issue? Thanks.
