| // |
| // This class is an observer for Android Messages for Web service worker |
| // lifecycle events and uses ConnectionEstablisher to initiate a background |
| // connection with Tachyon server when appropriate. Specifically, in the |
| // following cases |
| // 1. Startup. |
| // 2. Activation: This occurs on service worker update, when a new updated |
| // version of the service worker replaces the current active version or on |
| // service worker cold start. |
| // 3. NoControllees: When all pages controlled by the service worker are closed. |
| // The connection establishment may be attempted in more cases than actually |
| // required. It's left to the service worker to ignore or establish a background |
| // connection as required. E.g., The service worker will not establish a |
| // connection if it's is already connected to the Android Messages for Web page |
| // or if a connection already exists. |
