Updates various build dependencies and configurations for the Android build:
* Upgrade Android Gradle Plugin to 8.8.1
* Update Kotlin to 2.1.20-RC
* Upgrade NDK to 28.0.13004108
* Update target/compile SDK to Android 35
* Upgrade Java/Kotlin target to JVM 21
* Enable additional release optimizations (shrinkResources, proguard-android-optimize)
* Update CMake to 3.31.5
* Update various AndroidX and support library dependencies
* Change CMake boolean flags from 0/1 to OFF/ON
* Update ktlint to 0.51.1 and related plugins
This commit modernizes the Android build system and enables additional
optimizations for release builds.
Update fmt library to version 11.0.2 and make necessary adjustments:
- Replace fmt/format.h includes with fmt/ranges.h
- Add const qualifiers to formatter::format functions
- Update CMake to require fmt version 11
Additional dependency updates:
- Update SDL2 bundled version from 2.28.2 to 2.32.0
- Update catch2 to version 3.7.1
- Update vcpkg baseline to ca846b21276c9a3171074ac8d2b4f6516894a7d0
- Add network interface enumeration support for Android
- Implement fallback loopback interface when no interfaces are detected
- Add ability to force offline mode on critical network errors
- Improve socket initialization with better error handling
- Add socket state tracking (domain, type, protocol)
- Make translation functions static and mark as maybe_unused
- Add detailed logging for network initialization failures
Part 2 of the Android FPS bug fix focuses on network resilience,
particularly handling cases where network initialization fails.
Instead of hanging the emulator, it now gracefully falls back to
offline mode and provides better diagnostic information.
- Add new RAM usage overlay showing current/max memory usage with color gradient
- Simplify thermal overlay to show temperature in C/F with color indication
- Add SHOW_RAM_OVERLAY boolean setting (disabled by default in UI)
- Set default values for thermal overlay and black backgrounds to true
- Update copyright headers to include Citron Emulator Project
The RAM overlay displays native heap usage with color gradient from green
(low usage) to red (high usage). The thermal display was simplified to show
just temperatures while maintaining the color indication based on system
thermal status.
Updates Android build configuration to use newer versions:
- Upgrade Java/JVM target from 17 to 21
- Update Android Gradle Plugin from 8.1.2 to 8.8.0
These changes modernize the Android build system to use the latest LTS
version of Java and the most recent stable Android Gradle Plugin.
This enables access to newer language features and build optimizations
while maintaining compatibility with modern Android development tools.
Replaces the battery temperature reading implementation with a more
compatible approach using ACTION_BATTERY_CHANGED broadcast intent.
This change provides better backwards compatibility and adds proper
error handling for the temperature reading functionality.
Add stub implementations for previously unhandled flow test conditions in the
shader recompiler's IR emitter. These conditions were previously throwing
"Not Implemented" exceptions when encountered.
The following flow test cases are now stubbed:
- FCSM_TR (Fragment Shader Coarse/Fine Mode Test and Reject)
- CSM_TA (Coarse/Fine Mode Test Accept)
- CSM_TR (Coarse/Fine Mode Test and Reject)
- CSM_MX (Coarse/Fine Mode Maximum)
- FCSM_TA (Fragment Shader Coarse/Fine Mode Test Accept)
- FCSM_MX (Fragment Shader Coarse/Fine Mode Maximum)
Currently these stubs:
1. Return false (ir.Imm1(false)) as a placeholder value
2. Log a warning message indicating the stub
3. Allow shaders using these conditions to compile rather than fail
This is a step toward proper implementation of coarse/fine mode shader
operations. The stubs prevent crashes while making it clear which code paths
need full implementation.
Technical notes:
- Removed the previous FCSM_TR implementation that used flag operations
- Added consistent warning messages for tracking stub usage
- Kept within the existing GetFlowTest switch statement structure
Implements the USE_AUTO_STUB setting in the Android frontend:
- Added USE_AUTO_STUB to BooleanSetting enum
- Added UI switch setting with description in SettingsItem
- Added setting to system settings section in SettingsFragmentPresenter
- Added string resources for setting title and description
The setting allows users to toggle automatic stubbing of missing services
and functions, which may improve compatibility at the cost of stability.
- Replace emoji thermal indicators with modern progress bar UI
- Switch temperature source to battery sensor for better accuracy
- Adjust temperature thresholds (30°C-45°C range)
- Add automatic Vulkan Validation Layer download for Android
The thermal display now shows a visual progress bar with percentage
instead of emojis, making it easier to gauge system temperature at
a glance. Temperature reading now comes from the battery sensor
which is more reliable across devices.
Build system improvements include automated VVL binary downloads
and installation for Android builds when CITRON_DOWNLOAD_ANDROID_VVL
is enabled.
Bug discovered via an incomplete fix in Sudachi.
Some Progress Dialog callbacks pass the wrong type (Double instead of Long) from C++ to Java code causing a crash at runtime.
To fix this a new function is implemented to convert to a Java Long and that is used instead of the function that converts to a Double.

Update the dependencies of the Android app (used libraries and SDK). The Android SDK was not updated to the latest version, because then the build fails.
The `gradle-wrapper.jar` (the only binary blob touched in this PR) can be verified by checking against the official checksums [here](gradle-wrapper.jar).

Fixes x86_64 builds for Android by stubbing a function that calls into libadrenotools to query GPU driver information. libadrenotools is only available for arm64.
The function should not be called anyways, as the menu that would display the information is disabled on unsupported devices.
To enable x86_64 for building change the line `abiFilters += listOf("arm64-v8a")` in `src/android/app/build.gradle.kts` to `abiFilters += listOf("arm64-v8a", "x86_64")`.
I did not do this by default as it significantly increases the build time (the native part needs to be build once for each architecture) and increases the app size (this is less of a concern as games are already significantly larger).
It might allow usage on Chromebooks (the internet tells me those run on x86_64) and some few Android devices. The main advantage I see is for development of the app itself, as it allows running it in waydroid for local testing.

Removes the early access Android app variant from the build config and removes the get early access button from the settings tab.
I also tried to remove the code for the variant (different logo + colors) and the code for the button, but I am no Android developer so I might have missed some stuff.
Additionally I did not touch the translation files.
Essentially this gets rid of the now useless fancy button and improves build times as it only needs to build one apk now.

Adds a new option "On Load" to the "Optimize SPIRV output" option that turns on optimizations during the loading of the shader cache from disk, but turns it off after that.
The previous checkbox states have been named "Never" for unchecked and "Always" for checked.
The idea is that once the shader cache has most of the shaders in a game cached they can be optimized during initial game startup (where a performance hit matters less) and the few shaders that get compiled during runtime are not optimized to reduce performance hits.
Most of the commit is adding the setting to the Android app, the main logic is in the `gl_shader_cache.cpp` and `vk_pipeline_cache.cpp` files.

If you tried to connect a controller that was previously configured with an unsupported style for your game, when you try to connect that controller, it will immediately disconnect. This ensures that the controller that is being connected will be changed to the first supported style index before being connected.
Controls can have no mapping if they are either "[empty]" or and empty string. This was causing an issue if you reset mapping on all controllers and then tried to play a game. The check to determine whether auto mapping was required would fail and leave you will no mapped controllers. This feels a bit like user error but it smooths things out if you forget so I see it as necessary.
