Handling session, network state and http request

Question

In my application I am sending multiple http requests. Since, the network may go down at any time. So, before sending each request should I use android ConnectionManager to check the network state? I am feeling that some other better way would be there to handler this.(Rather than using the android connection manager service each time when multiple request are sent on each fragment)

Answer 1

Take a look at this question. If you want to avoid use of the ConnectionManager, you could use a try-catch block and check for an exception while trying to make a connection (provided you are using the java.net.* library to do the HTTP requests). For example, something like this was used in that question:

URL url = ...

HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setReadTimeout(15000);

try {
    InputStream in = new BufferedInputStream(c.getInputStream());
    httpResult = readStream(in);
} catch (IOException e) {

    // Here is where an exception would be thrown if there is no internet.
    // Would likely actually be an UnknownHostException

    Log.e(TAG, "Error: ", e);

} finally {
    c.disconnect();
}
