Fix several issues with the bottom sheet implementation, mostly
relating to what occurs when the bar is hidden.
Previously, if the bar was hidden and then re-shown, it would not be
visible, and you could override a hidden event with another tap. These
are now both resolved by removing a stray visibility assignment and
replacing the old drag checks with a new isDraggable attribute.
In the future, I hope to abuse BottomSheetBehavior into not being a
pile of garbage and replace this system once and for all.
Add new shortcut utilities for collecting StateFlows in a safe manner.
The priamry addition here is collectImmediately. collectImmediately
just calls block with the existing value initially, which helps remove
a good amount of bugs regarding state initialization. Sure, it is a bit
inefficient given that it will also initialize on startup, but this is
okay.
The other utilities are the same, but simply remove the launch
boilerplate.
Revamp the shared object SettingsManager into a standalone utility
called Settings.
This makes many things easier in Auxio. It completely unifies the key
format that we use (Android Strings instead of Java consts), eliminates
the pretty dumb initialization method that we use, and eliminates the
dubiousness of holding a Context-related utility in a global field.
The only cost was having to migrate even more ViewModels to Android
ViewModels. Whatever.
Add a dedicated service towards the loading of the music library.
This new service was created for two reasons:
1. Music loading is slow and resource-intensive, so putting it on the
ViewModel layer just didn't seem right and made it vulnerable to the
OS simply stopping the loading process.
2. For automatic rescanning [#72], there must be something watching
the music library and waiting for a change in the background. This
would require a service as that is probably the least insane way to
do that kind of background work.
I have no garuntees how viable the service might be. If anything, it
might be halted by some insane android restriction or issue that
makes it more or less impossible to use for most apps, and I will have
to largely drop truly automatic rescanning.
Rework loading management into a new object, Indexer, which should act
as the base for all future loading changes.
Indexer tries to solve a two issues with music loading:
1. The issue of what occurs when tasks must be restarted or cancelled,
which is common with music loading.
2. Trying to find a good strategy to mediate between service and
ViewModel components in a sensible manner.
Indexer also rolls in a lot of the universal music loading code
alongside this, as much of MusicStore's loading state went unused
by app components and only raised technical challenges when reworking
it.
Switch from LiveData to StateFlow.
While LiveData is a pretty good data storage/observer mechanism, it has
a few flaws:
- Values are always nullable in LiveData, even if you make them
non-null.
- LiveData can only be mutated on Dispatchers.Main, which frustrates
possible additions like a more fine-grained music status system.
- LiveData's perks are exclusive to ViewModels, which made coupling
with shared objects somewhat cumbersome.
StateFlow solves all of these by being a native coroutine solution with
proper android bindings. Use it instead.
Move the loading screen into the home view.
Previously, we would use a Snackbar to track the music loading state.
This ended up being a pretty stupid and buggy idea, and would get even
worse with the new music loader changes. Instead, we re-implement the
loading screen into the home view to generally be more sane and
extendable compared to previously.
Create separate routines to parse disc and track numbers in the most
optimal manner.
On API 30 (Android R) and above, ensure that we are using the superior
CD_TRACK_NUMBER and DISC_NUMBER database fields, while below API 30,
stick with the normal TRACK field.
Rework the tiny widget to cram even more information into it.
The tiny widget is nominally meant for edge cases like exceptionally
small screens or landscape mode, but apparently it's triggered on some
devices in normal use because of platform fragmentation and OEM insanity.
Update the tiny widget layout with some new buttons in order to make it
more usable in mnormal use. This is still nowehre near ideal. For
example, when triggering the layout on my device, it ends up squishing
the buttons. But it should probably work better outside of those edge
cases.
Hack around more insane lollipop bugs, such as:
- The angular auxio icon crashing the system UI
- Optimized icons being corrupted
- Setting image alpha not working properly
I really wish I could drop support for this horrible version, but I
either have to wait for a major library to drop support or for the
usage numbers to reach 1%.
Replace the hodge-podge framework of state restoration and URI playing
with a single "delayed action" system.
Auxio's initialization routine is a total cluster----. This is mostly
because it involves multiple asynchronous operations such as music
loading, state restore, and service starting which tend to make it
highly prone to race conditions and other insanity.
In particular, the way Auxio would attempt to restore playback and
handle file opening was a spaghetti pile of bad API boundaries and
dubious UI code. This has not changed. I want to move this routine
to the service, but it's lifecycle is also sh------ed to such an
extent where that would be nearly impossible. Instead, this commit
introduces a new "delayed action" system that bites the bullet and
allowes PlaybackViewModel to accept a context and an action in
return for initializing playback...eventually.
I tried my best to eliminate as much memory leaks as I physically
could here, but could only go so far. Still though, even this insane
system is better than the UI-level LiveData shenanigans I did
previously, and actually works compared to the broken android
components that google keeps wanting you to use.
Remove references to android system strings, in favor of in-house
translations.
Previously Auxio would use the `android.R.string.ok` and
`android.R.string.cancel` strings to represent Ok and Cancel
respectively, but these system strings are actually untranslated on
some devices, so it is better for i18n if we use our own strings
for such.
Rework the asynchronous aspects of MusicStore to rely on a more
conventional callback system.
In preparation for automatic rescanning, it would be more elegant
for music consumers to use a callback, so that updates can be
registered easier than if a co-routine continued to be used.
Convert MusicStore to this new model and rework the accesses of
MusicStore in-app to line up with this new system.
Create a ViewModel for the more complicated navigation pathways.
Normally, navigation was fragmented along a complicated stretch of
fragment hacks and DetailViewModel's navToItem attitbute, both of which
were not really that ideal. Dumpster them for a single, unified
viewmodel for the more complicated navigation situations. This removes
much of the duplicate navigation logic and is likely much more
maintainable for future situations.
Move all fragment instances to the new ViewBindingFragment paradigm,
which should help immensely with reducing memory leaks from list
bindings and to really alleviate the overloaded onCreate functions.
Rework the playback slide up implementation to be more straightfoward.
This is really composed of stylistic improvements, very little in
actual behavior changes. This does re-introduce a regression when
nothing is playing where the scroll position will become off when
rotating, but that desynchronization happens often so unless I were
to completely migrate both the panel and the bar to a view, I don't
really see it as an issue.
Switch to the spotless linter with ktfmt used as a backend instead of
ktlint.
This switch was done for two reasons:
1. ktfmt is more thorough than ktlint
2. License headers can be added more effectively with spotless than
the default Android Studio behavior.
Dump all of the changes now so I don't have to deal with it over a long
period of time. I don't care.
Change createMosaic to use SquareFrameTransform.
This should help fix a theoretical bug where non-1:1 album covers will
be oddly stretched in a generated mosaic, as all album covers will be
forcefully cropped to a 1:1 ratio.
Create a custom view for rounded images, making them more nuanced in
the process.
The previous method for applying rounded images in-app was generally
clunky and fragile. Introduce a new custom view that actually takes a
cornerRadius attribute from the ImageView itself that then applies it
whenever the user enables the setting. This also allows rounded images
to be more nuanced, as typical 8dp elevation can be used for small
views and a more fitting 16dp radius can be used for large views.
Rework logging to be clearer and more standardized.
Rework all usages of lossing to follow a single unified style,
introducing a new "warn" option alongside this.
Switch auxio to a single-queue system. "Play next" adds songs to the top
of the queue, similar to before, and then "Add to queue" adds songs to
the bottom of the queue. This enables many more enhancements to be made
to the playback experience, at the cost of a feature I preferred.
Resolves#44.
Split screen layouts in android are completely borked. You can
resize Auxio down to the point where the UI is completely
unusable, and there is NO WAY TO SET A MINIMUM HEIGHT. This is
also not to mention that smallestScreenWidthDp is completely
busted too and still uses the size of the whole screen! Just
band-aid the first issue so that when the layout becomes so
small as to result in a messed up UI, just show a splash that
says that the app can't work at the specific window size.
Turns out playback controls wouldn't actually work because the view
would detach but not the actual fragment, resulting in onCreateView
never being called and the entire system falling apart. This fixes
it by just giving PlaybackLayout the viewmodel instance it needs.
I'll need to release a hotfix for this issue since this is really
easy the trigger and really hard to fix unless you know why it
occurs. Android lifecycles suck so much.
Completely refactor PlaybackBarLayout into PlaybackLayout, which now
not only handles the bar behavior but also allows for one to slide
up the bar layout into the full playback layout. This was largely
adapted from umano's AndroidSlidingUpPanel, albeit heavily minified
and mixed with the previous window inset tricks of the previous layout.
There are still some tweaks to be made, but this implementation seems
to be really good.
Upgrade to coil 2.0.0 and completely refactor the usage of coil to work
with the new library structure. This also fixes the issue where error
icons will just re-appear due to blocking calls. I had to add a fix on
my end and also use the new caching system in coil 2.0.0.
Change CompactPlaybackFragment into a View. This completely fixes the
issue I tried to band-aid in ae39054. The code is a bit uglier, but
that's tolerable.
Move the main loading response code to MainFragment and add a new
method for other objects to be notified of the progress of the
music loading process. There's probably a better way to do this,
but kotlin coroutines are so complex that I don't know where I
would start. This also adds some enhancements, such as the error
message now showing in more parts of the app and SearchFragment
now re-running the query if the MusicStore instance is loaded.
Make MusicLoader instantiation fully asynchronous. This implementation
changes a lot about Auxio. For one, the loading screen is now gone.
However, many parts of the app now run under the fact that MusicStore
might not be available. However, I don't think there will be too much bugs
from it. Some more changes will be made to improve this implementation.
Make playback/about UIs follow the new liftOnScroll and edge-to-edge
idioms. This finally allows me to collapse a lot of duplicate code
into MainActivity and in general reduce code mess.
Once again fix annoying issues that arise from the quirks of phone
landscape mode. A lot of these fixes can be re-rolled back into the
edge-to-edge code eventually, but it requires fitsSystemWindows to
be phased out entirely.
