title: Read SMS in Android
body: <pre><code>Uri uri = Uri.parse( "content://sms/inbox" );
  
  Cursor cursor = context.getContentResolver().query(
                              uri,
                    new String[] { "_id", "thread_id", "address", "person", "date", "body" },
                              null,
                              null,
                              SORT_ORDER);
  </code></pre>
  
  <p>In the above code, for example, "body" is content of the message, "address" is the phone number.<br>
  So what are "_id" and "thread_id"? Can you give me a example to support explaination? </p>
