- Move all database queries off the ui thread - this is a massive
performance improvement
- ViewModel for MainActivity - this makes MainActivity smaller and
network requests won't be retried when rotating the screen
- removes the Push Notification Migration feature. We had it long
enough, all users who want push notifications should be migrated by now
- AccountEntity is now immutable
- converted BaseActivity to Kotlin
- The header image of Accounts is now cached as well
Hilt is an annotation processor built on top of Dagger which allows to
remove all the Android dependency injection boilerplate code (currently
around 900 lines) by writing it for us.
Hilt can use KSP instead of Kapt so Kapt can be completely removed from
the project. Kapt is slow, deprecated and has a few compatibility
issues. Removing Kapt will improve build times since no Java stubs have
to be generated for Kotlin classes anymore (Note that KSP also processes
annotations in Java classes so it can completely replace Kapt).
- Remove all modules related to manual dependency injection
configuration.
- Rename `AppModule` to `StorageModule` since it now only contains
configuration to retrieve the DataBase and SharedPreferences.
- Annotate all entry points (Activities, Fragments, BroadcastReceivers
and Services) with `@AndroidEntryPoint`.
- Annotate all injected ViewModels with `@HiltViewModel` and replace the
custom ViewModel Factory with the default one (which integrates with the
one generated by Hilt).
- Add a public field to allow overriding the default
ViewModelProvider.Factory in `BaseActivity` in tests.
- Annotate tested Activities with `@OptionalInject` since Activity tests
currently rely on the Activities not being injected automatically.
- Annotate injected `Context` arguments with `@ApplicationContext`. Hilt
provides the `Context` binding automatically but requires to specify if
the Application or Activity Context is wanted.
- Add WorkManager Hilt integration so all Workers are injected by Hilt
automatically using `HiltWorkerFactory`.
- Lazily initialize WorkManager in `TuskyApplication`.
- Remove Kapt and Kapt workarounds.
- ~~Remove toolchain configuration for Java 21. Toolchains force the
Java bytecode to match the JDK version used to build the project, and
apparently Hilt doesn't run inside the toolchain so cannot process the
source code if the JDK version of the toolchain is higher than the JDK
used to run Gradle. [And configuring a toolchain for an older Java
version causes other
issues](https://jakewharton.com/gradle-toolchains-are-rarely-a-good-idea/).
**Removing toolchains configuration doesn't prevent the project from
being built using JDK 21** or more recent versions but allows to build
the project using older JDKs as well.~~
Added a fix to allow Hilt to properly use the JDK toolchain.
- ~~Set the Java and Kotlin bytecode target to Java 17. The standard
bytecode target for Android projects is usually Java 8 or 11 (any higher
version doesn't provide any benefit but may cause compatibility issues).
However, since the app currently uses a library built against Java 17
bytecode (`networkresult-calladapter`), it needs to target at least Java
17 bytecode as well.~~
- Update the Dagger 2 URL in the licenses screen. Hilt is part of Dagger
2 so the label wasn't changed.
This refactors the NotificationsFragment and related classes to Kotlin &
paging.
While trying to preserve as much of the original behavior as possible,
this adds the following improvements as well:
- The "show notifications filter" preference was added again
- The "load more" button now has a background ripple effect when clicked
- The "legal" report category of Mastodon 4.2 is now supported in report
notifications
- Unknown notifications now display "unknown notification type" instead
of an empty line
Other code quality improvements:
- All views from xml layouts are now referenced via ViewBindings
- the classes responsible for showing system notifications were moved to
a new package `systemnotifications` while the classes from this
refactoring are in `notifications`
- the id of the local Tusky account is now called `tuskyAccountId` in
all places I could find

This pull request removes the remaining RxJava code and replaces it with
coroutine-equivalent implementations.
- Remove all duplicate methods in `MastodonApi`:
- Methods returning a RxJava `Single` have been replaced by suspending
methods returning a `NetworkResult` in order to be consistent with the
new code.
- _sync_/_async_ method variants are replaced with the _async_ version
only (suspending method), and `runBlocking{}` is used to make the async
variant synchronous.
- Create a custom coroutine-based implementation of `Single` for usage
in Java code where launching a coroutine is not possible. This class can
be deleted after remaining Java code has been converted to Kotlin.
- `NotificationsFragment.java` can subscribe to `EventHub` events by
calling the new lifecycle-aware `EventHub.subscribe()` method. This
allows using the `SharedFlow` as single source of truth for all events.
- Rx Autodispose is replaced by `lifecycleScope.launch()` which will
automatically cancel the coroutine when the Fragment view/Activity is
destroyed.
- Background work is launched in the existing injectable
`externalScope`, since using `GlobalScope` is discouraged.
`externalScope` has been changed to be a `@Singleton` and to use the
main dispatcher by default.
- Transform `ShareShortcutHelper` to an injectable utility class so it
can use the application `Context` and `externalScope` as provided
dependencies to launch a background coroutine.
- Implement a custom Glide extension method
`RequestBuilder.submitAsync()` to do the same thing as
`RequestBuilder.submit().get()` in a non-blocking way. This way there is
no need to switch to a background dispatcher and block a background
thread, and cancellation is supported out-of-the-box.
- An utility method `Fragment.updateRelativeTimePeriodically()` has been
added to remove duplicate logic in `TimelineFragment` and
`NotificationsFragment`, and the logic is now implemented using a simple
coroutine instead of `Observable.interval()`. Note that the periodic
update now happens between onStart and onStop instead of between
onResume and onPause, since the Fragment is not interactive but is still
visible in the started state.
- Rewrite `BottomSheetActivityTest` using coroutines tests.
- Remove all RxJava library dependencies.
There are some new rules, I think they mostly make sense, except for the
max line length which I had to disable because we are over it in a lot
of places.

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.
