| * |
| * {@link TRANSPORT_GONE} means we have no reason to show the transport - remove it if present. |
| * |
| * {@link TRANSPORT_INVISIBLE} means we have potential to show the transport because a music |
| * player is registered but not currently playing music (or we don't know the state yet). The |
| * code adds it conditionally on play state. |
| * |
| * {@link #TRANSPORT_VISIBLE} means a music player is active and transport should be showing. |
| * |
| * Once the transport is showing, we always show it until keyguard is dismissed. This state is |
| * maintained by onSave/RestoreInstanceState(). This state is cleared in |
| * {@link KeyguardViewManager#hide} when keyguard is dismissed, which causes the transport to be |
| * gone when keyguard is restarted until we get an update with the current state. |
