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.
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.
See
https://github.com/mastodon/documentation/issues/1216#issuecomment-2030222940
`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.
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
Previously to view a list the user either had to add it to a tab, or tap
through "Lists" in the navigation menu to their list of lists, and then
tap the list they want.
Fix that, and show all their lists in a dedicated section in the menu,
with a new "Manage lists" entry that's functionality identical to the
old "Lists" entry (i.e., it shows their lists and allows them to create,
delete, and edit list settings).
To do that:
- Implement a proper `ListsRepository` as the single source of truth for
list implementation throughout the app. Expose the current list of lists
as a flow, with methods to perform operations on the lists.
- Collect the `ListsRepository` flow in `MainActivity` and use that to
populate the menu and update it whenever the user's lists change.
- Rewrite the activities and fragments that manipulate lists to use
`ListRepository`.
- Always show error snackbars when list operations fail. In particular,
the HTTP code and error are always shown.
- Delete the custom `Either` implementation, it's no longer used.
- Add types for modelling API responses and errors, `ApiResponse` and
`ApiError` respectively. The response includes the headers as well as
the body, so it can replace the use of `NetworkResult` and `Response`.
The actual result of the operation is expected to be carried in a
`com.github.michaelbull.result.Result` type. Implement a Retrofit call
adapter for these types.
Unit tests for these borrow heavily from
https://github.com/connyduck/networkresult-calladapter
Additional user-visible changes:
- Add an accessible "Refresh" menu item to `ListsActivity`.
- Adding a list to a tab has a dialog with a "Manage lists" option.
Previously that would close the dialog when clicked, so the user had to
re-open it on returning from list management. Now the dialog stays open.
- The soft keyboard automatically opens when creating or editing a list.
New lint rules highlighted a potential crash; the use of named match
groups (used here when extracting server versions) requires API >= 26 or
throws an exception.
Use the group numbers instead of names when extracting the value, but
keep the group names in the regular expressions for readability.
The previous code used synchronous (i.e., non-suspending) functions to
call the /api/v2/search and /api/v2/accounts/search endpoints.
This is not necessary as the search was always performed in a separate
thread.
Remove, and replace their usage with the equivalent functions that
suspend.
A filter's context (previously referred to as its `kind`) controls where
the filter is applied.
This was implemented as an enum with a specific property to control how
it would serialise when @FormUrlEncoded, and with a @Json annotation for
Moshi.
In addition, the model objects kept the filter context in its string
form throughout Pachli, requiring periodic conversion to/from the enum
type, making the code more complicated.
Fix this, by:
1. Converting the incoming JSON value to the enum type immediately, so
the rest of the code uses the enum constants exclusively.
2. Implement a Retrofit converter that serialises the enum value when
@FormUrlEncoded to the same string used in JSON serialisation
Many servers that claim to be Mastodon-API compatible are not, as
evidenced by the content they include in the responses to
`/api/v1/instance` and `/api/v2/instance` requests.
Work around the worst of the breakage by providing defaults or marking
some fields as nullable (with a default null).
Bugs have been reported against the relevant projects.
Some servers don't include a `urls` or `translation` block, which was
preventing parsing of the block, and falling back to the v1 instance
data.
Fix this by providing sensible defaults.
The `highlighted` property on a role may be absent. If it is this breaks
account parsing, including accounts in an /api/v2/instance response.
This, in turn, breaks determining server capabilities, including whether
or not translation is supported.
Set the default to `true`, which matches observed Mastodon behaviour.
Previous code expected all incoming enums values to map directly to
Kotlin enum constants.
This is a problem for servers with additional features -- e.g.,
"reaction" as a notification type.
Fix this with a new Moshi adapter that will set the incoming value to a
given constant if it's not recognised.
Apply this to the enum constants in core.network to ensure they are
handled.
Clean up enum handling in Converters.kt, ComposeViewModel.kt, and
Status.kt by using the existing `.ordinal` property and some extension
functions for idiomatic code.
Fixes#461
Previous code showed a generic placeholder for audio media on the
account's "Media" tab.
Fix this so the preview image is shown (if it's available).
- Move the "is this attachment previewable?" code to `Attachment` so it
can be reused here.
- Restructure the logic in `AccountMediaGridAdapter` to use the new
`isPreviewable()` method when deciding whether to show a preview.
- Attachments have dedicated placeholder drawables, use those when the
preview is not available.
Friendica can return a null `voted_on` property, in violation of the API
spec.
Introduce a `BooleanIfNull` annotation that will convert the `null` to
`false` if encountered.
While I'm here update the other adapters as classes on their relevant
annotations instead of standalone classes to keep the code consistent.
Fixes#455
Some users report that Pachli is not retrieving/displaying notifications
in a timely fashion.
To assist in diagnosing these errors, provide an additional set of tabs
on the "About" screen that contain information about how Pachli is
fetching notifications, and if not, why not.
Allow the user to save notification related logs and other details to a
file that can be attached to an e-mail or bug report.
Recording data:
- Provide a `NotificationConfig` singleton with properties to record
different aspects of the notification configuration. Update these
properties as different notification actions occur.
- Store logs in a `LogEntryEntity` table. Log events of interest with a
new `Timber` `LogEntryTree` that is planted in all cases.
- Add `PruneLogEntryEntityWorker` to trim saved logs to the last 48
hours.
Display:
- Add a `NotificationFragment` to `AboutActivity`. It hosts two other
fragments in tabs to show details from `NotificationConfig` and the
relevant logs, as well as controls for interacting with them.
Bug fixes:
- Filter out notifications with a null tag when processing active
notifications, prevents an NPE crash
Other changes:
- Log more details when errors occur so the bug reports are more helpful
The `x` and `y` properties in `Attachment.Focus` may be null (not
documented as such, but observed in the wild).
Provide a `DefaultIfNull` adapter that can be applied to these to
replace null values with a sensible default.
- Use format strings so any overhead of building the string is only
incurred if the message is actually logged
- Pass throwables as the first parameter so they are logged with the
stacktrace
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,

Continue modularisation by moving activities in the "About" feature to a
new `feature.about` module.
Implement `feature.about:
- Move `AboutActivity`, `LicenseActivity`, and `PrivacyPolicyActivity`
here.
- Update `markdown2resource` plugin to work with libraries
Implement `core.data`:
- Types and repositories used through the app
- Move `InstanceInfo` and `InstanceInfoRepository` here so they are
available to `feature.about`.
Implement `core.ui`:
- App-specific views, spans, and other UI content
- Move `ClickableSpanTextView` and `NoUnderlineURLSpan` here so they are
available to `feature.about`.
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
Previous code could return an error on Friendica version strings like
`2024.03-dev-1547`.
Fix this:
- Extend the list of explicitly supported servers to include Fedibird,
Friendica, Glitch, Hometown, Iceshrimp, Pixelfed, and Sharkey.
- Add version parsing routines for these servers.
- Test the version parsing routines fetching every server and version
seen by Fediverse Observer (~ 2,000 servers) and ensuring that the
server and version information can be parsed.
Improve the error message:
- Show the hostname with a `ServerRepository` error
Clean up the code:
- Remove the custom `resultOf` and `mapResult` functions, they have
equivalents in newer versions of the library (like `runSuspendCatching`)
Fixes#372
Commit 993b7469 inadvertently broke this by removing the @SerializedName
annotation, so the user's display name was always null and the UI fell
back to showing the username.
Fixes#371
The previous code unilaterally enabled filter functionality. Some
Mastodon-like servers -- like GoToSocial -- do not support filters, and
this resulted in user visible error messages when connecting to those
servers.
To fix this:
- Extend the set of supported server capabilities to include client and
server side filtering.
- Disable the filter preferences if the server does not support filters
and show a message explaining why it's disabled.
Extend the capabilities model to support this:
- Fetch server software name and version from the nodeinfo endpoints
(implementing the nodeinfo API and schema)
- Extend the use of kotlin-result to provide hierarchies of Error
classes and demonstrate how to chain errors and display more informative
messages without using exceptions.
Fixes#343
Roles for the logged in user appeared in Mastodon 4.0.0 and can be
displayed on the user's profile screen.
Show them as chips, adjusting the display of the existing "Follows you"
and "Bot" indicators to make allowances for this.
Roles can have a custom colour assigned by the server admin. This is
blended with the app colour so it is not too jarring in the display.

The package wasn't renamed when it was moved, so was still
`app.pachli.components.timeline`, instead of the new location,
`app.pachli.core.network.model`.
The existing code base is a single monolithic module. This is relatively
simple to configure, but many of the tasks to compile the module and
produce the final app have to run in series.
This is unnecessarily slow.
This change starts to split the code in to multiple modules, which are:
- :core:account - AccountManager, to break a dependency cycle
- :core:common - low level types or utilities used in many other modules
- :core:database - database types, DAOs, and DI infrastructure
- :core:network - network types, API definitions, and DI infrastructure
- :core:preferences - shared preferences definitions and DI
infrastructure
- :core:testing - fakes and rules used across different modules
Benchmarking with gradle-profiler shows a ~ 17% reduction in incremental
build times after an ABI change. That will improve further as more code
is moved to modules.
The rough mechanics of the changes are:
- Create the modules, and move existing files in to them. This causes a
lot of churn in import arguments.
- Convert build.gradle files to build.gradle.kts
- Separate out the data required to display a tab (`TabViewData`) from
the data required to configure a tab (`TabData`) to avoid circular
dependencies.
- Abstract the repeated build logic shared between the modules in to
a set of plugins under `build-logic/`, to simplify configuration of
the application and library builds.
- Be explicit that some nullable types are non-null at time of use.
Nullable properties in types imported from modules generally can't be
smart cast to non-null. There's a detailed discussion of why this
restriction exists at
https://discuss.kotlinlang.org/t/what-is-the-reason-behind-smart-cast-being-impossible-to-perform-when-referenced-class-is-in-another-module/2201.
The changes highlight design problems with the current code, including:
- The main application code is too tightly coupled to the network types
- Too many values are declared unnecessarily nullable
- Dependency cycles between code that make modularisation difficult
Future changes will add more modules.
See #291.
