/**
 * A simple method that handles making an http request. Although we simplify this example since
 * we know what type of request is coming in, we leave it at a more generic standing to show
 * how a more complicated case can be handled.
 *
 * @param url The target URL. For GET operations, all the query parameters need to be included
 * here directly. For POST requests, use the <code>query</code> parameter.
 * @param method Can be {@link com.google.devrel.wcl.connectivity.WearHttpHelper#METHOD_GET}
 * or {@link com.google.devrel.wcl.connectivity.WearHttpHelper#METHOD_POST}
 * @param query Used for POST requests. The format should be
 * <code>param1=value1&param2=value2&..</code>
 * and it <code>value1, value2, ...</code> should all be URLEncoded by the caller.
 *
 * @throws IOException/*www.  j  av a2 s. co m*/
