title: how to listen for multiple else if statements
body: <p>my app receives SMS, reads the string, and performs a special action for every string. this works fine if i send a single string in one SMS. However, i want it to be able to work with multiple strings in a single SMS.</p>
  
  <pre><code>if (message.toLowerCase().contains("silent")) {
                      silent(context);
                  } else if (message.toLowerCase().contains(
                          "loud")) {
                      loud(context);
                  } else if (message.toLowerCase().contains("mute")) {
                      mute(context);
  </code></pre>
  
  <p>i want it to launch both <code>loud(context);</code> and <code>mute(context);</code> if my SMS contains both the strings.</p>
