| 81 | * Show or hide network provisioning notifications. |
| 82 | * |
| 83 | * We use notifications for two purposes: to notify that a network requires sign in |
| 84 | * (NotificationType.SIGN_IN), or to notify that a network does not have Internet access |
| 85 | * (NotificationType.NO_INTERNET). We display at most one notification per ID, so on a |
| 86 | * particular network we can display the notification type that was most recently requested. |
| 87 | * So for example if a captive portal fails to reply within a few seconds of connecting, we |
| 88 | * might first display NO_INTERNET, and then when the captive portal check completes, display |
| 89 | * SIGN_IN. |
| 90 | * |
| 91 | * @param id an identifier that uniquely identifies this notification. This must match |
| 92 | * between show and hide calls. We use the NetID value but for legacy callers |
| 93 | * we concatenate the range of types with the range of NetIDs. |
Lorenzo Colitti | 9be58c5 | 2016-09-15 14:02:29 +0900 | [diff] [blame] | 94 | * @param nai the network with which the notification is associated. For a SIGN_IN, NO_INTERNET, |
| 95 | * or LOST_INTERNET notification, this is the network we're connecting to. For a |
Lorenzo Colitti | 5526f9c | 2016-08-22 16:46:40 +0900 | [diff] [blame] | 96 | * NETWORK_SWITCH notification it's the network that we switched from. When this network |
| 97 | * disconnects the notification is removed. |
| 98 | * @param switchToNai for a NETWORK_SWITCH notification, the network we are switching to. Null |
| 99 | * in all other cases. Only used to determine the text of the notification. |
