I made a mistake in https://github.com/tuskyapp/Tusky/pull/4389🙄
With `addDynamicShortcuts` the limit can still be exceeded,
`setDynamicShortcuts` is what we want.
Also, `setLongLived` says:
> Sets if a shortcut would be valid even if it has been
unpublished/invisible by the app (as a dynamic or pinned shortcut). If
it is long lived, it can be cached by various system services even after
it has been unpublished as a dynamic shortcut.
I don't think we want that so I removed it.
The only crash so far in the 25.0-beta1 crash reports. Probably not a
regression though as that code did not change in a while.

- Read license resource using Okio inside a coroutine (instead of the
main thread) in `LicenseActivity`
- Use Okio and its buffer system to copy ContentProvider streams and
files to a temporary file in `MediaUploader.prepareMedia()`
- Properly close the input file after copying it to a temporary file in
`MediaUploader.prepareMedia()`
- Properly close sink in case of null body source during file copy in
`Uri.copyToFolder()` in `DraftHelper.kt`
- Add comment explaining the current value of `DEFAULT_CHUNK_SIZE` in
`UriRequestBody.kt` and indent the file properly
- Replace hardcoded `Charset` and `Int` byte size with the proper
constants, and align the `hashCode()` implementation with other
`BitmapTransformation` implementations in
`CompositeWithOpaqueBackground`
- Properly close `InputStream` in case of error during Bitmap size
decoding in `getImageSquarePixels()`
- return `Int` instead of `Long` in `getImageSquarePixels()`, since the
current code simply converts the `Int` result to a `Long` _after_
multiplication and not before (and `Int.MAX_VALUE` is already way above
the maximum number of pixels a decoded Bitmap could return)
- Simplify `getImageOrientation()`
- Add explicit dependency to the Okio library and upgrade it to its
latest version.
This pull request takes advantage of the Okio library to simplify, fix
or improve performance of some I/O related code in Tusky.
- Return early or throw `FileNotFoundException` early in case
`contentResolver.openInputStream()` returns `null` instead of throwing
`NullPointerException` later. Change the signature of
`Closeable.closeQuietly()` to only accept a non-null `Closeable`.
- Reimplement `Uri.copyToFile()` using Okio. This takes advantage of the
built-in high-performance buffers of the library so a buffer doesn't
need to be allocated or managed manually. The new implementation also
makes sure that the input and output streams are always closed, as the
original code could in some cases return without properly closing a
stream.
- Reimplement `ProgressRequestBody` as `Uri.asRequestBody()` (adding to
the existing extension functions available in the Okio library to create
a `RequestBody`). The new implementation uses Okio's `Buffer` instead of
a manually managed byte array, which allows to avoid copying bytes from
one buffer to the next. The max number of bytes read at once was
increased from 2K to 8K to improve performance. Avoid division by zero
in case `contentLength` is `0`. Finally, this implementation now takes a
`Uri` as input instead of an `InputStream`, because a `RequestBody` must
be replayable in case Okio retries the request, and an `InputStream` can
only be used once.
This also improves randomness by avoiding to reinitialize the random
number generator repeatedly from a seed based on the current time.
Typically, if the number generator is reinitialized repeatedly at
non-random times (like multiple times in a row), then generated numbers
have a higher chance of repeating.
The Kotlin Random object is only initialized once, using the best seed
available for the current Android version.
**! ! Warning**: Do not merge before testing every API call and database
read involving JSON !
**Gson** is obsolete and has been superseded by **Moshi**. But more
importantly, parsing Kotlin objects using Gson is _dangerous_ because
Gson uses Java serialization and is **not Kotlin-aware**. This has two
main consequences:
- Fields of non-null types may end up null at runtime. Parsing will
succeed, but the code may crash later with a `NullPointerException` when
trying to access a field member;
- Default values of constructor parameters are always ignored. When
absent, reference types will be null, booleans will be false and
integers will be zero.
On the other hand, Kotlin-aware parsers like **Moshi** or **Kotlin
Serialization** will validate at parsing time that all received fields
comply with the Kotlin contract and avoid errors at runtime, making apps
more stable and schema mismatches easier to detect (as long as logs are
accessible):
- Receiving a null value for a non-null type will generate a parsing
error;
- Optional types are declared explicitly by adding a default value. **A
missing value with no default value declaration will generate a parsing
error.**
Migrating the entity declarations from Gson to Moshi will make the code
more robust but is not an easy task because of the semantic differences.
With Gson, both nullable and optional fields are represented with a null
value. After converting to Moshi, some nullable entities can become
non-null with a default value (if they are optional and not nullable),
others can stay nullable with no default value (if they are mandatory
and nullable), and others can become **nullable with a default value of
null** (if they are optional _or_ nullable _or_ both). That third option
is the safest bet when it's not clear if a field is optional or not,
except for lists which can usually be declared as non-null with a
default value of an empty list (I have yet to see a nullable array type
in the Mastodon API).
Fields that are currently declared as non-null present another
challenge. In theory, they should remain as-is and everything will work
fine. In practice, **because Gson is not aware of nullable types at
all**, it's possible that some non-null fields currently hold a null
value in some cases but the app does not report any error because the
field is not accessed by Kotlin code in that scenario. After migrating
to Moshi however, parsing such a field will now fail early if a null
value or no value is received.
These fields will have to be identified by heavily testing the app and
looking for parsing errors (`JsonDataException`) and/or by going through
the Mastodon documentation. A default value needs to be added for
missing optional fields, and their type could optionally be changed to
nullable, depending on the case.
Gson is also currently used to serialize and deserialize objects to and
from the local database, which is also challenging because backwards
compatibility needs to be preserved. Fortunately, by default Gson omits
writing null fields, so a field of type `List<T>?` could be replaced
with a field of type `List<T>` with a default value of `emptyList()` and
reading back the old data should still work. However, nullable lists
that are written directly (not as a field of another object) will still
be serialized to JSON as `"null"` so the deserializing code must still
be handling null properly.
Finally, changing the database schema is out of scope for this pull
request, so database entities that also happen to be serialized with
Gson will keep their original types even if they could be made non-null
as an improvement.
In the end this is all for the best, because the app will be more
reliable and errors will be easier to detect by showing up earlier with
a clear error message. Not to mention the performance benefits of using
Moshi compared to Gson.
- Replace Gson reflection with Moshi Kotlin codegen to generate all
parsers at compile time.
- Replace custom `Rfc3339DateJsonAdapter` with the one provided by
moshi-adapters.
- Replace custom `JsonDeserializer` classes for Enum types with
`EnumJsonAdapter.create(T).withUnknownFallback()` from moshi-adapters to
support fallback values.
- Replace `GuardedBooleanAdapter` with the more generic `GuardedAdapter`
which works with any type. Any nullable field may now be annotated with
`@Guarded`.
- Remove Proguard rules related to Json entities. Each Json entity needs
to be annotated with `@JsonClass` with no exception, and adding this
annotation will ensure that R8/Proguard will handle the entities
properly.
- Replace some nullable Boolean fields with non-null Boolean fields with
a default value where possible.
- Replace some nullable list fields with non-null list fields with a
default value of `emptyList()` where possible.
- Update `TimelineDao` to perform all Json conversions internally using
`Converters` so no Gson or Moshi instance has to be passed to its
methods.
- ~~Create a custom `DraftAttachmentJsonAdapter` to serialize and
deserialize `DraftAttachment` which is a special entity that supports
more than one json name per field. A custom adapter is necessary because
there is not direct equivalent of `@SerializedName(alternate = [...])`
in Moshi.~~ Remove alternate names for some `DraftAttachment` fields
which were used as a workaround to deserialize local data in 2-years old
builds of Tusky.
- Update tests to make them work with Moshi.
- Simplify a few `equals()` implementations.
- Change a few functions to `val`s
- Turn `NetworkModule` into an `object` (since it contains no abstract
methods).
Please test the app thoroughly before merging. There may be some fields
currently declared as mandatory that are actually optional.
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.
builds upon work from #4082
Additionally fixes some deprecations and adds support for [predictive
back](https://developer.android.com/guide/navigation/custom-back/predictive-back-gesture).
I also refactored how the activity transitions work because they are
closely related to predictive back. The awkward
`finishWithoutSlideOutAnimation` is gone, activities that have been
started with slide in will now automatically close with slide out.
To test predictive back you need an emulator or device with Sdk 34
(Android 14) and then enable it in the developer settings.
Predictive back requires the back action to be determined before it
actually occurs so the system can play the right predictive animation,
which made a few reorganisations necessary.

Found with Leak canary: The transformation ends up in Glide's memory
cache and leaks whole Activities through the view -> context reference.
This fixes the problem by removing the background detection logic (so
the view reference is no longer needed) and setting the background
directly instead. Looks exactly as before.
While helping test an issue with
[Bookwyrm](https://github.com/bookwyrm-social/bookwyrm) I noticed that
the URL formats used by that project aren't checked as possible profile
or post links. They're quite close to a couple of others, so I just
copied close examples and edited a couple of terms.
It's pretty minor, I just used a previous commit as a reference. Let me
know if it needs anything more though. I've only quickly tested it on a
local build with a couple of links against a live Bookwyrm and it picks
them up as expected now.
Set the "System Design" as the default theme.
This ensures that the app's initial behaviour respect's the user's system-wide theme choice, while still allowing the user to adjust it later.
This is only done for new installs of Tusky. If the user is upgrading from a previous release and they did not have an explicit theme set then the dark theme is used, and the UX does not change.
Before, intent creation was scattered across multiple sites, with account switching logic in both `ComposeActivity` and `MainActivity`.
Now, intents are only created in `MainActivity` Companion, and account switching only occurs in `MainActivity`

Prevent users from accidentally deleting filters by prompting them to confirm.
Add an AlertDialog extension that converts AlertDialog callbacks to linear control flow.
Fixes#3736.
Avatars that are semi-transparent are a problem when viewing a thread,
as the line that connects different statuses in the same thread is drawn
underneath the avatar and is visible.
Fix this with a CompositeWithOpaqueBackground Glide transformation that:
1. Extracts the alpha channel from the avatar image
2. Converts the alpha to a 1bpp mask
3. Draws that mask on a new bitmap, with the appropriate background
colour
4. Draws the original bitmap on top of that
So any partially transparent areas of the original image are drawn over
a solid background colour, so anything drawn under them will not appear.
Update to Kotlin 1.9.0 and migrate to newer language idioms.
- Remove unnecessary @OptIn for features migrated to mainstream
- Use `data object` where appropriate
- Use new enum `entries` property
Instead of repeating the same if/else check on the error type when setting up the background message, move this in to BackgroundMessageView.
Provide different `setup()` variants, including one that just takes a throwable and a handler, and figures out the correct drawables and error message.
Update and simplify call sites.
The Android libraries have a bug where a TextView can forget that it contains selectable text, can be pasted in to, etc.
See https://issuetracker.google.com/issues/37095917
Fix this with an extension method that toggles the selectable state to re-enable it, and use this on the profile fields when editing an account.

Introduce Flow<T>.throttleFirst(). In a flow this emits the first value,
and each value afterwards that is > some timeout after the previous
value.
This prevents accidental double-taps on UI elements from generating
multiple-actions.
The previous code used debounce(). That has a similar effect, but with
debounce() the code has to wait until after the timeout period has
elapsed before it can process the action, leading to an unnecessary
UI delay.
With throttleFirst a value is emitted immediately, there's no need
to wait. It's subsequent values that are potentially throttled.
formatNumber() was existing code to show numbers with suffixes like K, M, etc, so re-use that code and delete shortNumber().
Update the tests to (a) test formatNumber(), and (b) be parameterised.
