Fixes a crash that could occur if the static constructor function for
the MainSettings.cpp TU happened to run before the variables in
Common/Version.cpp are initialised. (This is known as the static
initialisation order fiasco.)
By using wrapper functions, those variables are now guaranteed to be
constructed on first use.
It's a complete coincidence that both SIDEVICE_GC_CONTROLLER (6)
and SIDEVICE_WIIU_ADAPTER (12) are divisible by 6. Dividing
by 6 because of that doesn't make sense, especially not if we
want to add support for more kinds of SI devices on Android later.
Turns out that most phones ship with a special Google version of
DocumentsUI instead of just using the AOSP version, despite the two
being pretty similar as far as I can tell. This change makes us
check for both package names instead of just the AOSP package name.
Netplay: Fix possible Wii save restore race condition between Netplay and CPU threads on game shutdown by making the Wii Save Sync data part of the BootParameters.
I haven't fully confirmed why the previous commit broke this,
but I imagine it's due to AfterDirectoryInitializationRunner
executing in a different order than before, resulting in
startRescan running before startLoad.
This decreases our APK size by a few megabytes. Most of the reduction
is from Java libraries that we only use small parts of. Code shrinking
gets rid of all the unused code from these libraries from the APK.
Because I highly value the ability to get stack traces that make
sense, I have specifically disabled obfuscation (automatic renaming
of symbols to short incomprehensible names).
I've only enabled code shrinking for release builds, purely because
I feel like the extra build time (30 seconds on my machine)
would be annoying when you want to make debug builds rapidly.
This commit changes the default value of Fast Texture Sampling to true, and also moves the setting that controls it to the experimental section of the advanced tab. This is its own commit so that it can be easily reverted when we want to default to Manual Texture Sampling.

Gets rid some uses of the deprecated LocalBroadcastManager.
One note about the changes in GameFileCacheManager itself:
The change from compareAndSet to getValue followed by
setValue is actually safe, because startLoad and startRescan
only run from the main thread, and only the main thread ever
sets the flags to true. So it's impossible for any other thread
to change the flag in between the getValue and the setValue.
The past few Android releases have been adding restrictions
to what services are allowed to do, for the sake of stopping
services from using up too much battery in the background.
The IntentService class, which GameFileCacheService uses,
was even deprecated in Android 11 in light of this.
Typically, the reason why you would want use a service instead of
using a simple thread or some other concurrency mechanism from the
Java standard library is if you want to be able to run code in the
background while the user isn't using your app. This isn't actually
something we care about for GameFileCacheService -- if Android wants
to kill Dolphin there's no reason to keep GameFileCacheService
running -- so let's make it not be a service.
I'm changing this mainly for the sake of future proofing, but there
is one immediate (minor) benefit: Previously, if you tried to launch
Dolphin from Android Studio while your phone was locked, the whole
app would fail to launch because launching GameFileCacheService
wasn't allowed because Dolphin wasn't considered a foreground app.
Unlike with Android 11, there should be no downsides to doing
this, so we might as well get this out of the way early.
The main part of the work was already done in 5a1a642.
This should make C++20 and std::filesystem work. (Not that
we really can use std::filesystem much on Android since
it doesn't work with scoped storage...)
This makes Android ask the user whether they want to delete user
data when uninstalling the app instead of always deleting user data,
which is pretty great now that we're forced to use scoped storage.
It only works on Android 10 and up, though.
When I made 9c8bb24, I assumed it was completely impossible for a
non-preloaded app to access the entirety of the Android/data/ folder
on Android 11. This turned out to be false. While you can't access
the directory without using SAF (even if you have the Manage All
Files permission), and the user can't navigate to the folder using
the SAF folder picker, what you can do is pass the Android/data/
folder as an EXTRA_INITIAL_URI to the SAF folder picker. If the
user then presses "use this folder" without navigating out of the
folder, the app will be able to access the folder using SAF.
So what does that mean for Dolphin? It means scoped storage is a
little less bad than I feared, and I have a string to adjust.
This replaces the MAX_LOGLEVEL define with a constexpr variable
in order to fix self-comparison warnings in the logging macros
when compiling with Clang. (Without this change, the log level check
in the logging macros is expanded into something like this:
`if (LINFO <= LINFO)`, which triggers a tautological compare warning.)
Yes, that's right! It's time to add even more NKit warnings,
because users still don't understand what NKit is or how it works!
More specifically, some users seem to be under the impression that
converting an NKit file to for instance RVZ using Dolphin's convert
feature will result in a normal RVZ file, when it in fact results in
an NKit RVZ file (since NKit is not a container format in the sense
that GCZ/WIA/RVZ/WBFS/CISO is, but rather a kind of trimmed ISO).
I can hardly blame users for not knowing this, because it's not
intuitive unless you know the technical details of how NKit works.
The purpose of this class was to keep track of state which the
emulation core was already keeping track of. This is rather risky -
if we update the state of one of the two without updating the other,
the two become out of sync, leading to some rather confusing problems.
This duplicated state was removed from EmulationState in the
previous commits, so now there isn't much left in the class.
Might as well move its members directly into EmulationFragment.
Apparently some phones (at least some from Samsung) don't expose the
system file manager in the system settings despite it being the
only on-device file manager that can open app-specific directories...
This enables scoped storage for new Dolphin installs on Android 11
and up (along with a few other changes in behavior which unlike
scoped storage are uncontroversial). Existing installs are unaffected.
We have to do this in order to be able to release updates on
Google Play from November 2021 and on.
The following settings are currently not SAF compatible,
and might never be due to the performance impact:
Dump Path
Load Path
Resource Pack Path
Wii NAND Root
This commit makes us show a message to the user if they try to
change one of these settings while scoped storage is active.
I don't want to entirely remove the settings from being listed
in the settings activity, because it's important that the user
is able to reset them if they were set to something custom in
a previous version of Dolphin.
This lets Dolphin function without the user granting access to
external storage. We need this for scoped storage compatibility.
When scoped storage is not active, we still ask for permission to
access external storage the first time the app is started so that
we can use the existing dolphin-emu folder if there is one. But
if it doesn't exist, or the user denies the permission, or scoped
storage is active, the app-specific directory will be used instead.
Special shoutout to Android for not having RTL compatible
variants of nextFocusRight and nextFocusLeft.
Ideally we would have some way to block the user from using
the d-pad to switch between the two panes when in portrait mode,
or make the list pane act as if it's to the left of the details
pane rather than the right when the details pane is open, but I
don't know of a good way to do this. SlidingPaneLayout doesn't
really seem to have been implemented with d-pad navigation in mind.
Thankfully, landscape is the most important use case for gamepads.
The way I'm implementing events using LiveData feels rather
unorthodox, but I'm not aware of anything in the Android framework
that would let me do it in a better way... One option I did
consider was wrapping the cheat lists in LiveData and observing
those, but then CheatsAdapter wouldn't know which cheat had
changed, only that there was some kind of change to the list,
necessitating the use of the not recommended notifyDataSetChanged.
This path isn't really any faster in the normal case,
but it does let us skip waiting for the lock to be available,
which makes a huge difference if the lock is already taken.
It seems like we spend a lot of the game list scanning time in
updateAdditionalMetadata, which I suppose makes sense considering
how many different files that function attempts to open.
With the addition of just one little atomic operation, we can make
it safe to call updateAdditionalMetadata without holding a lock.
FindAllGamePaths may take a little while, and holding the
gameFileCache lock isn't actually necessary until it's time to
put the results returned by FindAllGamePaths into gameFileCache.
The downside of this change is that we have to do an extra
round of JNI in between FindAllGamePaths and Update,
but I don't think that's much of a problem.
