38 * A TileService provides the user a tile that can be added to Quick Settings.
39 * Quick Settings is a space provided that allows the user to change settings and
40 * take quick actions without leaving the context of their current app.
42 * <p>The lifecycle of a TileService is different from some other services in
43 * that it may be unbound during parts of its lifecycle. Any of the following
44 * lifecycle events can happen indepently in a separate binding/creation of the
48 * <li>When a tile is added by the user its TileService will be bound to and
49 * {@link #onTileAdded()} will be called.</li>
51 * <li>When a tile should be up to date and listing will be indicated by
52 * {@link #onStartListening()} and {@link #onStopListening()}.</li>
54 * <li>When the user removes a tile from Quick Settings {@link #onTileRemoved()}
55 * will be called.</li>
57 * <p>TileService will be detected by tiles that match the {@value #ACTION_QS_TILE}
58 * and require the permission "android.permission.BIND_QUICK_SETTINGS_TILE".
59 * The label and icon for the service will be used as the default label and
60 * icon for the tile. Here is an example TileService declaration.</p>
