* Fetch all outstanding Mastodon notifications when creating Android notifications
Previous code fetched the oldest page of unfetched Mastodon notifications.
If you had more than a page of Mastodon notifications you'd get Android notifications for that page, then ~ 15 minutes later Android notifications for the next page, and so on.
This code fetches all the outstanding notifications at once.
If this results in more than 40 total notifications the list is still trimmed so that a maximum of 40 Android notifications is displayed.

* Build the list using buildList
Don't use `accountManager.activeAccount` throughout the code.
Instead, get the active account once, and use that over the life of the viewmodel.
As shown in https://github.com/tuskyapp/Tusky/issues/3689#issuecomment-1567219338 the active account can change before the view model is destroyed, and if that happens account information for the account will be written to the wrong account.
Fix a bug where the active account can be overwritten.
1. Have two accounts logged in to Tusky, A and B
2. Open Tusky as account A
3. Send a DM to account B (doesn't have to be a DM, just anything that creates a notification for account B)
4. Restart Tusky so the Android notification for the DM is displayed immediately. You are still acting as account A.
5. Drag down the Android notification, you should see two options, "Quick reply" and "Compose"
6. Tap "Compose"
7. ComposeActivity will start. You are now acting as account B. Compose and send a reply
8. You'll be returned to the "Home" tab.
The UI will show you are still account A (i.e., it's account A's avatar at the top of the screen, if you have the "Show username in toolbars" option turned on it will be account A's username in the toolbar).
But you are now seeing the home timeline for account B.
Fix this.
ComposeViewModel
- Do not rely on the active account in sendStatus(), receive the account ID as a parameter
ComposeActivity
- Use either the account ID from the intent, or the current active account. **Do not** change the active account
- Pass the account ID to use in the sendStatus() call
The previous code gets the user's reading position *once*, when the
viewmodel is created, and uses that whenever it needs to be restored.
This is a problem. Suppose the user is a few days behind on their
notifications, and opens the app.
The reading position is restored, as expected. They scroll up to start
reading newer notifications.
Then they change their notification filters. This causes the
notifications list to change, and when it does their reading position
is set back to what it was when they first switched to the Notifications
tab.
Fix this by:
NotificationsFragment:
- Save the reading position whenever the user stops scrolling.
NotificationsViewModel:
- Use the saved reading position whenever the list of notifications
can change, not just when the view model is created.
Not all servers support the marker API. If they don't the user will
potentially get duplicate Android notifications.
To resolve this, store a copy of the notification marker ID locally as
well. Defer to the remote marker if it exists (and is newer than the
local marker).
Fixes https://github.com/tuskyapp/Tusky/issues/3671
When fetching:
- Maintain a marker with the position of the newest fetched notification
- Use the marker to determine which notifications to fetch
- Fetch notifications with min_id to ensure that none are lost
- Update the marker as necessary
- Perform a one-time immediate fetch of notifications on startup
When creating notifications:
- Identify each notification with tag=${MastodonNotificationId}, id=${account.id}
- Remove activeNotifications field, it's no longer necessary
- Use the tag/id tuple to reliably identify existing notifications and avoid creating duplicates
- Cancelling notifications for an account must iterate over all the notifications, and individually remove the notifications that exist for that account.
- Limit notifications to a maximum of 40 (excluding summary notifications)
- Remove notifications (oldest first) to get under this limit
- Rate limit notification creation to 1 per second, so the OS won't drop them
Adjust the summary notification:
- Ensure the summary notification and the child notifications have the same group key
- Dismiss the summary notification if there is only one child notification
NotificationClearBroadcastReceiver is no longer needed, so remove it, and the need for deletePendingIntent.
