Previous code assumed the active account could always be determined from
the account manager.
This causes a few problems.
1. The account manager has to handle the case where there is no active
account (e.g., the user is logging out of the last account). This meant
the `activeAccount` property had to be nullable, so every consumer of
that property either used it with a `let` or `!!` expression.
2. The active account can change over the life of the UI component, for
example, when the user is switching accounts. There's a theoretical race
condition where the UI component has started an operation for one
account, then the account changes and the network authentication code
uses the new account.
3. All operations assume they operate on whatever the active account is,
making it difficult to provide any features that allow the user to
temporarily operate as another account ("Boost as...", etc).
This "ambient account" was effectively global mutable state, with all
the problems that can cause.
Start to fix this. The changes in this commit do not fix the problem
completely, but they are some progress.
Each activity (except LoginActivity) is expected to be launched with an
intent that includes the ID of the Pachli account it defaults to
operating with. This is `pachliAccountId`, and is the *database ID*
(not the server ID) of the account. This is non-null, which removes one
class of bugs.
This account is passed to each fragment and any piece of code that has
to perform an operation on behalf of this account. It's not used in
most of those places yet, that will be done over a number of followup
PRs as part of modernising each module.
Previous code didn't encode v2 filter keywords, so created v2 filters by
first creating the filter with no keywords (one API call) then making
1-N API calls to add each keyword to the filter.
Fix this by adding a dedicated converter for the `NewContentFilter` type
that encodes it correctly so the filter can be created with a single API
call.
This necessitates moving some types around,
The new anti-harassment features will add several different types of
filtering options through the UI.
To ensure there is no confusion, rename the existing "Filters" UI and
code to "Content filters" to accurately describe what they operate on,
distinct from new filters which will act on account metadata.
Fixes#926.
Update `DownloadUrlUseCase` with a parameter to specify the account that
"owns" the media. This is either the account that posted the status, or
the account being viewed (e.g., if downloading an account's header
image).
Add a new `DownloadLocation` enum constant to download to directories
named after that account.
Pass this information through at the call sites.
Fixes#938
The previous code had a number of problems, including:
- Calls to the filters API were scattered through UI and viewmodel code.
- Repeated places where the differences between the v1 and v2 Mastodon
filters API had to be handled.
- UI and viewmodel code using the network filter classes, which tied
them to the API implementation.
- Error handling was inconsistent.
Fix this.
## FiltersRepository
- All filter management now goes through `FiltersRepository`.
- `FiltersRepository` exposes the current set of filters as a
`StateFlow`, and automatically updates it when the current server
changes or any changes to filters are made. This makes
`FilterChangeEvent` obsolete.
- Other operations on filters are exposed through `FiltersRepository` as
functions for viewmodels to call.
- Within the bulk of the app a new `Filter` class is used to represent a
filter; handling the differences between the v1 and v2 APIs is
encapsulated in `FiltersRepository`.
- Represent errors when handling filters as subclasses of `PachliError`,
and use `Result<V, E>` throughout, including using `ApiResult` for all
filter API results.
- Provide different types to distinguish between new-and-unsaved
filters, new-and-unsaved keywords, and in-progress edits to filters.
## Editing filters
- Accept an optional complete filter, or filter ID, as parameters in the
intent that launches `EditFilterActivity`. Pass those to the viewmodel
using assisted injection so the viewmodel has the info immediately.
- In the viewmodel use a new `FilterViewData` type to model the data
used to display and edit the filter.
- Start using the UiSuccess/UiError model. Refrain from cutting over to
full the action implementation as that would be a much larger change.
- Use `FiltersRepository` instead of making any API calls directly.
## Listing filters
- Use `FiltersRepository` instead of making any API calls directly.
## EventHub
- Remove `FilterChangedEvent`. Update everywhere that used it to use the
flow from `FiltersRepository`.
Implement suggestions as a new `feature:suggestions` module, with
associated activity, fragment, etc.
Suggested accounts are shown with their normal information, as well as
information about the number of follows / followers, and a guide to
posting frequency, so the user can make a more informed decision about
whether to follow or not.
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.
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
`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.
Previously the only way to access notifications was to dedicate a tab to
them. Now notifications are available from the left-side navigation menu
so they're always accessible.
Add them to the top of the list, and swap the order of bookmarks and
favourites, assuming that users are more likely to want to see their
bookmarks than their favourites.
Move "Edit profile" to the bottom with the other settings options,
assuming that editing their profile does not happen very often, so
should not be at the top of the list.
The previous code didn't clear the task stack or recreate `MainActivity`
when the active user was changed.
So if the user was logged in with account A and used "Compose" from a
notification sent to account B, the active account was switched to B but
the UI chrome wasn't. After exiting `ComposeActivity` they would be
looking at the timeline for account B but with a toolbar that showed
account A.
Fix this by clearing the task stack and explicitly recreating
`MainActivity` when forwarding intents to `ComposeActivity`.
Moshi is faster to decode JSON at runtime, is actively maintained, has a
smaller memory and method footprint, and a slightly smaller APK size.
Moshi also correctly creates default constructor arguments instead of
leaving them null, which was a source of `NullPointerExceptions` when
using Gson.
The conversion broadly consisted of:
- Adding `@JsonClass(generateAdapter = true)` to data classes that
marshall to/from JSON.
- Replacing `@SerializedName(value = ...)` with `@Json(name = ...)`.
- Replacing Gson instances with Moshi in Retrofit, Hilt, and tests.
- Using Moshi adapters to marshall to/from JSON instead of Gson `toJson`
/ `fromJson`.
- Deleting `Rfc3339DateJsonAdapter` and related code, and using the
equivalent adapter bundled with Moshi.
- Rewriting `GuardedBooleanAdapter` as a more generic `GuardedAdapter`.
- Deleting unused ProGuard rules; Moshi generates adapters using code
generation, not runtime reflection.
The conversion surfaced some bugs which have been fixed.
- Not all audio attachments have attachment size metadata. Don't show
the attachment preview if the metadata is missing.
- Some `throwable` were not being logged correctly.
- The wrong type was being used when parsing the response when sending a
scheduled status.
- Exceptions other than `HttpException` or `IoException` would also
cause a status to be resent. If there's a JSON error parsing a response
the status would be repeatedly sent.
- In tests strings containing error responses were not valid JSON.
- Workaround Mastodon a bug and ensure `filter.keywords` is populated,

Previously, `AboutActivity` had buttons and links to show the privacy
policy and licenses of dependencies.
Change this to a selection of fragments in tabs, one tab each for:
- General "About" information
- Licenses
- Privacy Policy
The information shown hasn't changed, but this lays the groundwork for
including additional tabs in the future for information like server
rules, detected capabilities, or troubleshooting information.
Continue modularisation by moving core activity classes that almost all
activities depende on to a `core.activity` module. This includes
core "helper" classes as well.
Implement core.activity:
- Contains BaseActivity, BottomSheetActivity
- Contains LinkHelper and other utility classes used by activities
Implement core.common.extensions:
- Move ViewBindingExtensions and ViewExtensions here
Implement core.common.util:
- Move BlurHashDecoder and VersionName here
Implement core.designsystem:
- Holds common resources (animations, colours, drawables, etc) used
through the app
- Import "core.designsystem.R as DR" through the app to distinguish
from the module's own resources
Implement feature.login:
- Move the LoginActivity and related code/resources to its own module
Implement tools/mvstring
- Moves string resources (and all translations) from one module to
another
The previous code generally started an activity by having the activity
provide a method in a companion object that returns the relevant intent,
possibly taking additional parameters that will be included in the
intent as extras.
E.g., if A wants to start B, B provides the method that returns the
intent that starts B.
This introduces a dependency between A and B.
This is worse if B also wants to start A.
For example, if A is `StatusListActivity` and B is`ViewThreadActivity`.
The user might click a status in `StatusListActivity` to view the
thread, starting `ViewThreadActivity`. But from the thread they might
click a hashtag to view the list of statuses with that hashtag. Now
`StatusListActivity` and `ViewThreadActivity` have a circular
dependency.
Even if that doesn't happen the dependency means that any changes to B
will trigger a rebuild of A, even if the changes to B are not relevant.
Break this dependency by adding a `:core:navigation` module with an
`app.pachli.core.navigation` package that contains `Intent` subclasses
that should be used instead. The `quadrant` plugin is used to generate
constants that can be used to launch activities by name instead of by
class, breaking the dependency chain.
The plugin uses the `Activity` names from the manifest, so when an
activity is moved in the future the constant will automatically update
to reflect the new package name.
If the activity's intent requires specific extras those are passed via
the constructor, with companion object methods to extract them from the
intent.
Using the intent classes from this package is enforced by a lint
`IntentDetector` which will warn if any intents are created using a
class literal.
