* 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.
Fixes https://github.com/tuskyapp/Tusky/issues/3648
* 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.
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.
Fixes#3625, #3539
Requesting a non-existent notification ID will cause the fall-back requests to succeed but return empty lists which stops pagination.
Check for this, and in the worst case, fall back to returning the most recent notifications.
The pageSize is large enough that there's no need for the default 3 x pageSize initialLoadSize value, and this improves performance.
Fixes https://github.com/tuskyapp/Tusky/issues/3578
This makes the notification view for a follow request contain more info about the new follower, and makes the layout (of their name / username) consistent with other notifications that show names/usernames.
* Show better errors with notification loading fails
The errors are returned as a JSON object, parse it, and show the error
message it contains.
Handle the cases where there might be no error message, or the JSON may be
malformed.
Add tests.
Fixes#3445
* Lint
The previous code returned the text representation of the error body type, which resulted in errors appearing in the UI as:
```
okhttp3.ResponseBody$Companion$asResponseBody$1@...
```
This code actually converts the *body* of the error response to a string, so the error is displayed correctly.
* Replace "warn"-filtered posts in timelines and thread view with placeholders
* Adapt hashtag muting interface
* Rework filter UI
* Add icon for account preferences
* Clean up UI
* WIP: Use chips instead of a list. Adjust padding
* Scroll the filter edit activity
Nested scrolling views (e.g., an activity that scrolls with an embedded list
that also scrolls) can be difficult UI.
Since the list of contexts is fixed, replace it with a fixed collection of
switches, so there's no need to scroll the list.
Since the list of actions is only two (warn, hide), and are mutually
exclusive, replace the spinner with two radio buttons.
Use the accent colour and title styles on the different heading titles in
the layout, to match the presentation in Preferences.
Add an explicit "Cancel" button.
The layout is a straightforward LinearLayout, so use that instead of
ConstraintLayout, and remove some unncessary IDs.
Update EditFilterActivity to handle the new layout.
* Cleanup
* Add more information to the filter list view
* First pass on code review comments
* Add view model to filters activity
* Add view model to edit filters activity
* Only use the status wrapper for filtered statuses

* Bare minimum necessary to demonstrate paging in notifications
Create `NotificationsPagingSource`. This uses a new `notifications2()` API
call, which will exist until all the code has been adapted. Instead of
using placeholders,
Create `NotificationsPagingAdapter` (will replace `NotificationsAdapater`)
to consume this data.
Expose the paging source view a new `NotificationsViewModel` `flow`, and
submit new pages to the adapter as they are available in
`NotificationsFragment`.
Comment out any other code in `NotificationsFragment` that deals with
loading data from the network. This will be updated as necessary, either
here, or in the view model.
Lots of functionality is missing, including:
- Different views for different notification types
- Starting at the remembered notification position
- Interacting with notifications
- Adjusting the UI state to match the loading state
These will be added incrementally.
* Migrate StatusNotificationViewHolder impl. to NotificationsPagingAdapter
With this change `NotificationsPagingAdapter` shows notifications about a
status correctly.
- Introduce a `ViewHolder` abstract class that all Notification view holders
derive from. Modify the fallback view holder to use this.
- Implement `StatusNotificationViewHolder`. Much of the code is from the
existing implementation in the `NotificationAdapater`.
- The original code split the code that binds values to views between the
adapter's `bindViewHolder` method and the view holder's methods.
In this code, all of the binding code is in the view holder, in a `bind`
method. This is called by the adapter's `bindViewHolder` method. This keeps
all the binding logic in the view holder, where it belongs.
- The new `StatusNotificationViewHolder` uses view binding to access its views
instead of `findViewById`.
- Logically, information about whether to show sensitive media, or open
content warnings should be part of the `StatusDisplayOptions`. So add those
as fields, and populate them appropriately.
This affects code outside notification handling, which will be adjusted
later.
* Note some TODOs to complete before the PR is finished
* Extract StatusNotificationViewHolder to a new file
* Add TODO for NotificationViewData.Concrete
* Convert the adapter to take NotificationViewData.Concrete
* Add a view holder for regular status notifications
* Migrate Follow and FollowRequest notifications

* Convert NotificationViewData to Kotlin
* Re-implement the reblog functionality
- Move reblogging in to the view model
- Update the UI via the adapter's `snapshot()` and `notifyItemChanged()`
methods
* Re-implement the favourite functionality
Same approach as reblog
* Re-implement the bookmark functionality
Same approach as reblog
* Add TODO re StatusActionListener interface
* Add TODO re event handling
* Re-implementing the voting functionality
* Re-implement viewing hidden content
- Hidden media
- Content behind a content warning
* Add a TODO re pinning
* Re-implement "Show more" / "Show less"
* Delete unused updateStatus() function
* Comment out the scroll listener for the moment
* Re-implement applying filters to notifications
Introduce `NotificationsRepository`, to provide access to the notifications
stream.
When changing the filters the flow is as follows:
- User clicks "Apply" in the fragment.
- Fragment calls `viewModel.accept()` with a `UiAction.ApplyFilter` (new
class).
- View model maintains a private flow of incoming UI actions. The new action
is emitted to that flow.
- In view model, `notificationFilter` waits for `.ApplyFilter` actions, and
ensures the filter is saved, then emits it.
- In view model, `pagingDataFlow` waits for new items from
`notificationsFilter` and fetches the notifications from the repository in
response. The repository provides `Notification`, so the model maps them to
`NotificationViewData.Concrete` for display by the adapter.
- In view model the UI state also waits for new items from
`notificationsFilter` and emits a new `UiState` every time the filter is
changed.
When opening the fragment for the first time:
- All of the above machinery, but `notificationFilter` also fetches the filter
from the active account and emits that first. This triggers the first fetch
and the first update of `uiState`.
Also:
- Add TODOs for functionality that is not implemented yet
- Delete a lot of dead code from NotificationsFragment
* Include important preference values in `uiState`
Listen to the flow of eventHub events, filtered to preference changes that
are relevant to the notification view.
When preferences change (or when the view model starts), fetch the current
values, and include them in `uiState`.
Remove preference handling from `NotificationsFragment`, and just use
the values from `uiState`.
Adjust how the `useAbsoluteTime` preference is handled. The previous code
loaded new content (via a diffutil) in to the adapter, which would trigger
a re-binding of the timestamp.
As the adapter content is immutable, the new code simply triggers a
re-binding of the views that are currently visible on screen.
* Update UI in response to different load states
Notifications can be loaded at the top and bottom of the timeline. Add a
new layout to show the progress of these loads, and any errors that can
occur.
Catch network errors in `NotificationsPagingSource` and convert to
`LoadState.Error`.
Add a header/footer to the notifications list to show the load state.
Collect the load state from the adapter, use this to drive the visibility
of different views.
* Save and restore the last read notification ID
Use this when fetching notifications, to centre the list around the
notification that was last read.
* Call notifyItemRangeChanged with the correct parameters
* Don't try and save list position if there are no items in the list
* Show/hide the "Nothing to see" view appropriately
* Update comments
* Handle the case where the notification key no longer exists
* Re-implement support for showMediaPreview and other settings
* Re-implement "hide FAB when scrolling" preference
* Delete dead code
* Delete Notifications Adapater and Placeholder types
* Remove NotificationViewData.Concrete subclass
Now there's no Placeholder, everything is a NotificationViewData.
* Improve how notification pages are loaded if the first notification is missing or filtered
* Re-implement clear notifications, show errors
* s/default/from/
* Add missing headers
* Don't process bookmarking via EventHub
- Initiating a bookmark is triggered by the fragment sending a
StatusUiAction.Bookmark
- View model receives this, makes API call, waits for response, emits either
a success or failure state
- Fragment collects success/failure states, updates the UI accordingly
* Don't process favourites via EventHub
* Don't process reblog via EventHub
* Don't process poll votes with EventHub
This removes EventHub from the fragment

* Fix saving changes to statuses when editing
With the previous code backing out of a status editing operation where changes
had been made (whether it was editing an existing status, a scheduled status,
or a draft) would prompt the user to save the changes as a new draft.
See https://github.com/tuskyapp/Tusky/issues/2704 and
https://github.com/tuskyapp/Tusky/issues/2705 for more detail.
The fix:
- Create an enum to represent the four different kinds of edits that can
happen
- Editing a new status (i.e., composing it for the first time)
- Editing a posted status
- Editing a draft
- Editing a scheduled status
- Store this in ComposeOptions, and set it appropriately everywhere
ComposeOptions is created.
- Check the edit kind when backing out of ComposeActivity, and use this to
show one of three different dialogs as appropriate so the user can:
- Save as new draft or discard changes
- Continue editing or discard changes
- Update existing draft or discard changes
Also fix ComposeViewModel.didChange(), which erroneously reported false if the
old text started with the new text (e.g., if the old text was "hello, world"
and it was edited to "hello", didChange() would not consider that to be a
change).

Only use distributors which are compatible with FEATURE_BYTES_MESSAGE
This is because Mastodon sends notifications that are arbritary bytes,
not UTF-8. This causes issues in older versions of UnifiedPush
distributors and providers that don't support FEATURE_BYTES_MESSAGE
Fixes#793.
This is an implementation for push notifications based on UnifiedPush
for Tusky. No push gateway (other than UP itself) is needed, since
UnifiedPush is simple enough such that it can act as a catch-all
endpoint for WebPush messages. When a UnifiedPush distributor is present
on-device, we will by default register Tusky as a receiver; if no
UnifiedPush distributor is available, then pull notifications are used
as a fallback mechanism.
Because WebPush messages are encrypted, and Mastodon does not send the
keys and IV needed for decryption in the request body, for now the push
handler simply acts as a trigger for the pre-existing NotificationWorker
which is also used for pull notifications. Nevertheless, I have
implemented proper key generation and storage, just in case we would
like to implement full decryption support in the future when Mastodon
upgrades to the latest WebPush encryption scheme that includes all
information in the request body.
For users with existing accounts, push notifications will not be enabled
until all of the accounts have been re-logged in to grant the new push
OAuth scope. A small prompt will be shown (until dismissed) as a
Snackbar to explain to the user about this, and an option is added in
Account Preferences to facilitate re-login without deleting local drafts
and cache.
