In the previous code `PachliError` could correctly chain errors and
generate error messages, `ApiError` didn't, which is why there was the
temporary `ApiError.fmt()` extension function.
Rewrite `ApiError` to implement `PachliError` so it gets these benefits
and to reduce the number of different error-handling mechanisms in the
code.
Main changes:
- `PachliError` is now an interface so it can be extended by other
error interfaces.
- All the `ApiError` subclasses implement `PachliError`, and can
specify the error string and interpolated variables at the point of
declaration.
- Update `ListsRepository` and `ServerRepository` to return
`PachliError` subclasses.
Previous code was inconsistent about using getServerErrorMessage() and
whether or not the case where getServerErrorMessage() returns null was
handled.
Switch to using getErrorString() which does handle the null case and
always returns a usable string.
Some string resources are rendered temporarily unused by this change.
They will be used again soon, so configure lint to ignore them at the
moment.
Previous code always included the transitionKind enum as an extra, and
could cause a crash if the activity launched by the intent was not a
Pachli activity.
Fixes#700.
Edited polls only include the list of options with titles; no other
metadata (poll ID, single/multiple choice, vote counts, etc). Since the
data shape didn't match Moshi wasn't decoding the data.
Provide dedicated data classes to model the response, and add a fourth
poll display option to represent viewing an edit history snapshot.
Crash was occuring because the instance info hadn't been fetched, trying
to take the last item of an empty list.
To fix:
- Expose the instance info as a state flow, with a default. New instance
info is fetched whenever the active account changes.
- Do the same for the emojis supported by the server.
- Update call sites as appropriate.
- Mark `InstanceInfoRepository` as `@Singleton` so it isn't repeatedly
created causing fresh content fetches.
The tests needed updating to get this to work.
- Extract the network fake modules in to a network-test module so
multiple other modules can use them.
- Rewrite `InstanceInfoRepositoryTest` to use Hilt and use Turbine to
test the new flows.
Checking this showed cosmetic bugs in the About layout when instance
info is missing, clean those up.
Previous code used a single animation type (slide) when transitioning,
the transition was quite slow, and didn't behave appropriately if the
device was set to a RTL writing system.
In addition, handling the back affordance didn't work well with the new
"Predictive Back" feature in Android 14
(https://developer.android.com/guide/navigation/custom-back/predictive-back-gesture).
Fix this.
## Transitions
To update the transitions the `startActivityWithSlideInAnimation()`
implementation (and associated `finishWithoutSlideOutAnimation()`) have
been replaced.
There are three transitions; `default`, `slide`, and `explode`,
represented as an enum passed to the activity intent.
The `default` transition is the activity transition from Android 14,
from the Android open source project
(https://cs.android.com/android/platform/superproject/+/android-14.0.0_r18:frameworks/base/core/res/res/anim/;bpv=1).
This is used for most transitions.
The `slide` transition is the pre-existing slide transition, with a
shorter transition time so it feels more responsive, and an RTL
implementation. This is used when there is a strong spatial component to
the navigation, for example, when going from:
- a status to its thread
- a preference menu item to its subscreen
- a filter in a list to the "edit filter" screen
- viewing your profile to editing your profile
The `explode` transition is used when the state of the app changes
significantly, such as when switching accounts.
Activities are now started with `startActivityWithTransition()` which
sets the intent and prepares the transition. `BaseActivity` checks the
intent for the transition type and makes further changes to the
transition as necessary.
## Predictive back
"Predictive back" needs to know what the back button would do before the
user interacts with it with an `onBackPressedCallback` that is either
enabled or disabled. This required refactoring some code (particularly
in `ComposeActivity`) to gather data ahead of time and enable/disable
the callback appropriately.
## Fixed bugs
- Back button wasn't stepping back through the tabs in AccountActivity
- Modifying a filter and pressing back without saving wasn't prompting
the user to save the changes
- Writing a content warning and then hiding it would still count the
text of the content warning toward's the post's length
## Other cleanups
- Use `ViewCompat.setTransitionName()` instead of setting the
`transitionName` property
- Delete the unused `fade_in` and `fade_out` animations.
- Use androidx-activity 1.9.0 to get the latest predictive back support
library code
- Show validation errors when creating / editing filters
The previous code didn't set a limit for the number of posts, links, and
hashtags to fetch on the trending pages, so used the conservative
defaults.
Increase these to the API maximums to show the user more information.
Abstract common CI setup tasks (setting up Java, Gradle, etc) in to a
single action that can be used by all CI workflows.
Run the lint, test, and assemble CI tasks in parallel for each variant
rather than in series, which cuts ~ 7 minutes (approx. 50%) off the CI
runtime.
Update code in checks and core/navigation to fix new tests.
Use `unicodeWrap` when inserting placeholders in error messages so they
set the correct text direction.
Update some strings with formatting directives to (a) include `_fmt`
in the name, and (b) use `%1$s` instead of `%s`.
Previously, modifying any tabs meant opening the left-side nav, opening
Account preferences > Tabs, and then adding / removing tabs. This is
time consuming, and difficult for new users to discover.
In addition, it was possible to remove the Home tab, and there was a
hardcoded minimum of at least two tabs.
Fix this.
When viewing a timeline that is not already in a tab an "Add to tab"
menu item is enabled, which appends the timeline to the list of existing
tabs.
When viewing a timeline in a tab (that is not the Home timeline) a
"Remove tab" menu item is enabled, which removes the tab from the list
of existing tabs.
If the user removes the active tab (either with this menu item, or
through preferences) the tab to the left of the active tab becomes the
new active tab.
A new "Manage tabs" menu item is also provided, as a shortcut to the
existing Account preferences > Tabs screen.
When managing tabs the Home timeline can not be removed; the button to
remove it is removed, and swiping is disabled on that list item. The
restriction of "at least two tabs" has also been removed.
`NotificationsActivity` has been removed, as `TimelineActivity` can
display `NotificationsFragment`.
To make the three "Trending" types (hashtags, links, and posts) more
visually distinct add two new icons for links (ic_newspaper) and posts
(ic_whatshot).
Fixes#572, #584, #585, #569
Mastodon API uses an "empty" `expires_in` value for a filter to mean
"Does not expire" (i.e., indefinite).
This was modelled as a null. Which doesn't work, because Retrofit does
not send name/value pairs in encoded forms if the value is null.
Fix this by making the API type a `String?`, and explicitly using the
empty string when indefinite expiry is used. This has to be converted
back to an Int? in a few places.

https://github.com/mastodon/documentation/issues/1216#issuecomment-2030222940
Previous code was inconsistent about how and when the FAB was hidden if
the user had set the relevant preference.
- Sometimes the FAB has hidden by setting the visibility to false, which
removed it with no animation.
- Sometimes the value of the preference was checked once, when the
fragment or activity was created.
- Some timelines didn't show the FAB (Hashtags, Favourites, Bookmarks,
TrendingLinks, TrendingStatuses).
- Logic for figuring out which `ComposeActivity` intent to use was
scattered across different files.
Improve this by:
- Expose changes to the `FAB_HIDE` preference in the relevant viewmodels
as a flow the UI component can collect.
- Centralise the show/hide logic in a new `ActionButtonScrollListener`
class, and always using `show()`/`hide()` to animate the transition.
- Centralise the logic for creating the `ComposeActivity` intent in
`TabViewData`.
`TabData` recorded the type of the timeline the user had added to a tab.
`TimelineKind` is another type that records general information about
configured timelines, with identical properties.
There's no need for both, so remove `TabData` and use `TimelineKind` in
its place.
`TimelineKind` is itself mis-named; it's not just the timeline's kind
but also holds data necessary to display that timeline (e.g., the list
ID if it's a `.UserList`, or the hashtags if it's a `.Hashtags`) so
rename to `Timeline` to better reflect its usage. Move it to a new
`core.model` module.
Previous code would handle some expected exceptions (IO, HTTP) when
fetching a timeline, and show them to the user. Any other exception
would crash.
Now, surface all exceptions. Treat IO and HTTP exceptions as retryable
and show the "Retry" option, all others are considered non-retryable.
Provide a specific error string for exceptions caused by bad JSON.
Previous code used custom regular expressions to extract URLs, hashtags,
and mentions from text while the user was writing a post. These were
inconsistent with the ones that Mastodon uses so the derived character
count could be wrong.
As well as being visually incorrect this could prevent the user from
posting a status that was within the length limit, or allow them to
attempt to post a status that was over the length limit (which would
then fail).
Fix this by dropping the homegrown regular expressions and using the
same text parsing library that Mastodon users; twitter-text. This has
been converted to Kotlin and the functionality related to Twitter
specific features has been removed.
The hashtag handling has been adjusted, as Mastodon is more permissive
about the positions where hashtags can appear than Twitter is, in
particular, a hashtag does not need to be preceded with whitespace if
the tag appears after some scripts, such as Hirigana.
Previous code expected callers to typically provide the drawable and the
error message string resource, resulting in duplicate code at many
callsites.
Replace with three canned messages for empty containers, generic errors,
and network errors respectively. The images for these are fixed, the
caller may choose a different string resource for the error if there is
a more specific option.
Update and simplify the call sites.
Move `ListsActivity`, along with fragments and viewmodels, to a new
`feature:lists` module.
Previous code used the `item_follow_request` layout, which was not
ideal, so update it to use a dedicated layout, `item_account_in_list`.
The UI uses strings and views originally defined in the main app, so
move them elsewhere so they can be re-used.
- `BackgroundMessageView` moves to `core.ui`.
- `Lazy` moves to `core.common`.
- `ThrowableExtensions` split; the extensions specific to throwables
from network activity move to `core.network`, others move to `core.ui`.
- `BindingHolder` moves to `core.ui`
- Shared drawables and strings move to `core.ui`.
The replies policy controls whether replies from members of the list
also appear in the list.
Display the replies policy as three radio buttons when a list is created
or updated, and send the chosen replies policy via the API.
Default value if not specified is always "list", for consistency with
the Mastodon API defaults.
While I'm here:
- Ensure the list dialog layout is inflated using the dialog's themed
context
- Use a `TextInputLayout` wrapper around the list name in the list
dialog for better UX
- Simplify the dialog layout, use LinearLayout, and standard padding and
margins
Previous code used a normal ProgressBar and a coroutine to delay
hiding/showing the bar for a snappier UI perception.
This is built-in functionality in LinearProgressIndicator, so switch to
that.
While I'm here, implement the "Select list" dialog's layout as a layout
resource.
