Phone

Glassly Miniapp SDK betaThe SDK is in beta, so its APIs may change before general availability.Developing on Mentra Live? We recommend using the Glassly Bluetooth SDK.The developer tools are available in the Glassly App under Settings → Miniapp Developer Settings.Share feedback with an in-app bug report, on Discord, or by email at help@glassly.ai.

session.phone reports state from the user’s phone: notifications as they post, calendar events, and the phone’s own battery. Each concern is its own sub-module. Register a handler and the events start arriving.

src/background/index.ts

session.phone.notifications.on((data) => {
  session.display.render([{type: "text", id: "msg", box: {x: 0, y: 0, w: 576, h: 288}, text: `${data.app}: ${data.title}`}]);
});

Notifications need the READ_NOTIFICATIONS permission and calendar events need the CALENDAR permission, both declared in your manifest. Phone battery needs no permission.

Notifications

session.phone.notifications.on() fires when a notification posts on the phone.

session.phone.notifications.on((data) => {
  // data: PhoneNotificationData
});

Each event is a PhoneNotificationData:

Field	Type	Notes
`notificationId`	`string`	Stable id from the phone’s notification listener.
`app`	`string`	Human app name (e.g. `"Messages"`).
`title`	`string`	The notification title.
`content`	`string`	The notification body.
`priority`	`string`	Android priority string; empty on iOS.
`timestamp`	`number`	Unix ms timestamp.
`packageName`	`string`	Reverse-DNS package/bundle id of the originating app.

Dismissals

session.phone.notifications.onDismissed() fires when the user swipes away or clears a notification.

session.phone.notifications.onDismissed((data) => {
  // data: NotificationDismissedData
});

Each event is a NotificationDismissedData:

Field	Type	Notes
`notificationId`	`string`	Same id as the matching post event from `notifications.on(...)`.
`notificationKey`	`string?`	Android NotificationKey. More stable than `notificationId` across reposts.
`packageName`	`string?`	Reverse-DNS package/bundle id of the originating app.
`timestamp`	`number`	Unix ms timestamp of the dismissal.

onDismissed is Android only. iOS does not expose dismiss callbacks to apps (an Apple privacy restriction), so subscribing on iOS succeeds but no events ever fire. The matching notifications.on() post-event works on both platforms.

Calendar

session.phone.calendar.listEvents() reads a current snapshot from all event calendars on the phone. Declare CALENDAR as a required permission; the Glassly App requests access before opening the miniapp.

const result = await session.phone.calendar.listEvents({
  startsAt: new Date(),
  endsAt: new Date(Date.now() + 7 * 24 * 60 * 60 * 1000),
  limit: 50,
});

The date window may span at most 31 days. limit defaults to 50 and may not exceed 100. The result contains events and a truncated flag. Each event has:

Field	Type	Notes
`id`	`string`	Unique occurrence id, including recurring instances.
`calendarId`	`string`	Id of the source calendar.
`title`	`string`	The event title.
`startsAt`	`string`	ISO 8601 start time. All-day events preserve their calendar timezone offset.
`endsAt`	`string`	ISO 8601 end time. All-day events preserve their calendar timezone offset.
`timezone`	`string?`	The event’s timezone.
`allDay`	`boolean`	Whether it’s an all-day event.
`location`	`string?`	The event location.
`notes`	`string?`	The event notes.
`url`	`string?`	The platform calendar URL field, when available.
`links`	`string[]`	Deduplicated HTTPS links found in URL, location, and notes.

Phone battery

session.phone.onBattery() reports the phone’s battery. It stays flat (not sub-namespaced) because it’s a single event.

session.phone.onBattery((data) => {
  // data: BatteryData
});

Each event is a BatteryData:

Field	Type	Notes
`level`	`number`	Battery level.
`charging`	`boolean`	Whether the phone is charging.

Cleaning up

Every subscription returns an unsubscribe function. The notifications sub-module also has a stop() that tears down every notification subscription at once. Calendar snapshots do not create a subscription.

const off = session.phone.notifications.on(handler);
off();                              // drop this one

session.phone.notifications.stop(); // drop all notification subscriptions

session.phone.notifications.hasPermission tells you whether READ_NOTIFICATIONS is declared in your manifest, and session.phone.calendar.hasPermission tells you whether CALENDAR is declared. Neither tells you whether the user granted the OS prompt. A calendar request rejects with PERMISSION_DENIED if access was later revoked. See Permissions.
