pspKeys and pspAxis were written from the input thread and the render

sending PSP button codes as keycodes, which released nothing; use
ControlMapper::ReleaseAll instead.
Input devices are now matched by ID. InputDevice objects are replaced after
device changes, so reference comparison registered the same device again.
Removing a device now releases what it was holding.

GetJavaString() returned Java's modified UTF-8, so input like emoji
reached C++ as invalid UTF-8. Commands to Java now get converted the other
way. Request IDs are made on several threads, and the permissions map was
written on the Java UI thread and read on the render thread. The frame
command debug log no longer prints params, which could hold a password.

processCommand were never answered, leaving the native side waiting (a

The Oboe input callback used to call Microphone::addAudioData directly,
writing PSP memory from the audio thread. Now it only pushes samples
into a SampleRing, and pollRecording drains it on the CPU thread.
Starting and stopping still go through Java, which asks for permission.
Every host with a microphone polls now, so sceUsbMic drops what only the
push path needed: QueueBuf's recursive mutex, restarting the mic on a
device change, and the startMic parameter nobody read. Also removes the
unused System_AudioRecordingState and Microphone::isNeedInput.
The Java microphone_command branch didn't return true, so every command
logged "processCommand failed".

Replaces the instance counter with a weak reference to the current activity,
and says in the log when an activity takes over, and when a replaced one skips
something because the native side isn't its anymore.
The render loop state is static now, with the activity whose surface it runs
on: there's one render thread. An activity only stops the loop if it runs on
its own surface, and one that finds another activity's loop still running
logs an error and stops it before starting its own.

Now that EGL is ours rather than GLSurfaceView's, the swap interval can be set,

onPause used to join the render thread and stop the audio, so anything taking
focus while the game stayed on screen (a permission dialog, a share sheet, the
other app of a split screen before Android 10) tore down the whole graphics
context and silenced the game. Emulation, audio, sensors and input listeners
now follow onStart/onStop. The render loop itself already follows the surface;
onStop joins it too, for devices that keep a stopped activity's surface.
The camera stays on onPause/onResume, as it goes to the focused app.
A finishing activity lets go of the render thread in onPause, since a quick
relaunch creates the next activity before this one's onStop, and that onStop
then leaves the audio and location updates alone.

- Initialize() runs for the first activity only, but set up per-activity
fields: after any recreate, audioManager was null, so audio focus was
never taken or given up again, and sustained performance mode was off.
- The static camera helper kept the first activity's display. It now gets
the application context.
- An activity backed out of (or destroyed by the system) with the native
side left running stayed referenced by it until the next one registered,
and native code could still post commands to it. It now lets go, and a
command arriving at a destroyed activity is dropped (an input box request
answered as cancelled).
- An open input box is dismissed in onDestroy, instead of its window
leaking and its request never being answered.

The C++ paths draw and sample four pixels at a time in vector lanes,
while a JIT function only does one, and with a JIT function in use the
span and quad paths were skipped. On x86 the JITs had become slower:
Wipeout took 13% more wall time and 25% more CPU with them, God of War
3% more. They were also a second implementation of every GE rule, and
ARM never had them.
The SoftwareRendererJit setting goes with them. RasterizerRegCache.h

Now that density is in configChanges, a density change no longer recreates
the activity - but it also doesn't resize the surface, so no surfaceChanged
follows it. The DPI is only recalculated in backbufferResize, so the UI kept
the old scale until the next real resize or a trip through the background.
Re-report the surface we already have when the density has moved. The native
side needs no change: Recalculate() already returns true when the dp size
changes, which a density change does on its own.
Also make the log line say which size changed, since the pixel size now stays
put in this case.

Now that rotation doesn't recreate the activity, the class is the
SurfaceHolder.Callback plus the hardware scaling logic, and the rest had
outlived its purpose:
- The deferred-surface-while-paused workaround. Also what started the
render thread twice on resume.
- The "bad orientation" workaround, which called recreate().
- The deprecated system UI visibility listener, which only chose between
getMetrics and getRealMetrics, and the view size overrode that whenever
it mattered anyway.
- The coalescing of display measurement updates, and updateDpi, which
updateDisplayMeasurements does itself.
Before the first layout the display size now comes from getRealMetrics.
It only feeds the first-run config defaults.

Every rotation, fold or window resize destroyed the activity and with it
all of graphics, then built it all up again. Declare those config changes
handled, so they arrive as a surfaceChanged and go through the same resize
path as a desktop window resize.
That path needed three things it didn't have on Android:
- The GPU_DISPLAY_RESIZED message, left out for Android since 2020 when
DeviceRestore covered every size change.
- A fixed (hardware scaled) surface size is now recomputed on each in-place
surface change, since surfaceCreated no longer runs on a rotation.
- A 180 degree flip keeps the size but changes the surface transform, so
the display rotation is passed along and a change in it is a resize too.

It was a debug aid that asserted the activity callbacks arrive in the order
Android promises. That has served its purpose - nothing has tripped it in a long
time, and the lifecycle work this sits on top of has been exercised hard.
What it also did, though, was log every callback, and that is worth keeping: the
begin/end pairs are what makes a bad startup or a surprise recreate legible in a
logcat. So the tracker goes and the Log.i calls stay, at the same points, under
this class's own tag instead of LifeCycle's.
onStart and onStop now only log, so they lose the no-native-binary guard. There
is nothing left in them to guard, and if the library is missing is exactly when
you want to see the callbacks.

When the library fails to load, onCreate shows a dialog and returns before

If startCamera threw after Camera.open (no usable preview size, say),

An intent arriving while we're running was passed on as a game path,
whole. That was right for a shortcut or a file association, but the Args
extra carries a command line, so its options got booted as a file.
Run it through the same parsing as at startup. The options can't be
applied anymore and aren't, but parsing them is what separates them (and
their arguments) from the game to boot. If there is none, do nothing.
This also unescapes a quoted path the same way NativeApp.init does, where
before only the quotes were stripped.

There is only one render thread, shared by whichever activity is
current. After a finish() and a quick relaunch, the old activity's surface
is destroyed about a second into the new activity's life, and joining the
thread from surfaceDestroyed then stopped the new activity's rendering.
Found by forcing the finish-then-relaunch order with a test hook: without
the previous commit the process died in NativeApp.shutdown(), with it the
app survived but went black until this was added.

After finish(), onDestroy may arrive after a new activity has already been

registerCallbacks took a new global ref to the activity on every onCreate
without releasing the previous one, and unregisterCallbacks only runs on a
real shutdown. Since rotation and resizing recreate the activity, each of
those leaked the old one, view hierarchy and all.
Releasing it means other threads can no longer use the raw global ref,
which had been copied into AndroidStorage and TextDrawerAndroid and was
read from the emu thread and IO threads. They now take a local ref under a
mutex (Android_GetActivity, and the equivalent inside AndroidStorage for
the shortcut activity's sake), so a call in flight keeps its activity
alive while the UI thread swaps in the new one.
The "no activity" bail is a null check on that local ref rather than a
separate HasActivity() test beforehand. Between such a test and the call
the UI thread can swap the activity out, and we'd hand null to a Java
method that wants a Context. The one remaining HasActivity() caller never
passes the activity on, so it has nothing to race with.
The ContentUri class ref and method IDs are now only looked up once,
instead of leaking a class ref per activity.
Headless and the unit test executable link Common but not app-android.cpp, so
they get a stub for this the same way they already do for getEnv and findClass.

Local refs are only freed automatically when a native method returns to
Java. The content URI functions mostly run on threads we attached
ourselves, where nothing ever freed the strings they created - two per
file open, one per exists check and so on. From Android 8 that's a slow
leak; before it the table has 512 slots and overflowing it aborts.
Add JNILocalFrame (PushLocalFrame/PopLocalFrame) and use it in all of
AndroidStorage.cpp, in the camera device list, and free the name string
in findClass.
Also: Android_GetFileInfo never released its GetStringUTFChars buffer, a
native leak on every call, and Android_ListContentUri called
GetArrayLength on a null array if the Java side returned none.

Stage 5 of the JavaGL removal. Now that the GL path owns its own EGL context and
render thread, Android's two lifecycle branches and the Win32 one in
MainThreadFunc were the same code three times over, so this moves the branch into
one place - RunGraphicsLoop() in Core/EmuThread.cpp. It picks the thread
arrangement the context asks for: either this thread becomes the render thread
and spawns the emu thread (OpenGL), or it just runs the main loop because the
backend spawns its own render thread (Vulkan, D3D11). Android, Windows and
headless all go through it now, which is what the "TODO: Merge with the Win32
EmuThread and so on" in app-android.cpp was asking for.
Falls out of having one implementation instead of three:
- MainThreadFunc called graphicsContext->ThreadStart() right after
EmuThread_Start(), which already calls it, and ThreadEnd() right after
EmuThread_Join(), which already calls that too. So Windows and headless GL ran
CreateDeviceObjects()/DestroyDeviceObjects() twice per context, leaking a VAO
on the way in and double-deleting it on the way out. Dates back to 16206d18ab,
which moved those calls into EmuThread_Start/Join without removing the
originals.
- RECREATE_VIEWS is gone. Only the GL path ever posted it; Vulkan goes through
the same destroy/recreate without it and always has. Verified on device: views
survive pause/resume, and both a real rotation and a density change - each one
an activity destroy and recreate - lay them out again by themselves.
- The non-separate path is now named EmuThread rather than MainThread on
Windows. It's the thread that runs NativeFrame(), which is what
DebuggerThreading.md calls the emu thread, and the real main thread there is
the GUI message pump.
The loop keeps an explicit exit flag, as a shouldExit callback, rather than
relying on ThreadFrame() returning false. In VR we skip ThreadFrame() entirely
while the XR session is idle, and the session going idle is exactly what
backgrounding the app does - so the exit would never be observed, the render
thread would sit in that sleep forever, and the UI thread joining it would hang.
That is not hypothetical: it deadlocked a Quest 2 on the first try.
Also drops a dead EmuThreadState enum and an unused JNIEnv local in
app-android.cpp, both orphaned when the JavaGL JNI entry points went away.
Tested on a nubia Z2464N (Mali-G57, Android 15) on both backends: cold start,
booting a homebrew, pause/resume in the menu, in a settings screen and in-game,
rotation back and forth, a density-change activity recreate with the game live,
the pause menu, and exit to menu. ThreadStart/ThreadEnd log exactly once per
context, and every one of those cycles tears the EGL context down and builds a
new one.
Also tested on a Quest 2 with the vr flavor, which is what shook out the deadlock
above: cold start into a focused XR session at 72fps, backgrounding (render
thread joins in 27ms where it used to never return), resuming back into VR with
a fresh EGL context, and exiting from in-app. xrCreateSession runs on the render
loop thread, which is where the EGL context is current - VRBase.cpp builds its
graphics binding from eglGetCurrentDisplay/eglGetCurrentContext, so that ordering
matters.
Windows x64 debug and the Android gradle builds are clean.
Not converged, and not a small change: NeedsSeparateEmuThread() itself. GL needs
its API calls on the thread its context is current on, so somebody has to pump
ThreadFrame() there, whereas VulkanRenderManager owns its thread outright.
Getting rid of the virtual means teaching GLRenderManager to spawn and own its
own render thread, for every GL platform at once.

The EGL path from the previous commit is now the only one, so GLSurfaceView
and everything that existed to serve it are gone:
- NativeRenderer.java and NativeGLSurfaceView.java, deleted.
- The javaGL branches in PpssppActivity. GL and Vulkan now share one
lifecycle: a plain SurfaceView, startRenderLoopThread() when the surface
arrives, joinRenderLoopThread() when it goes away.
- The "androidJavaGL" queryConfig, and the AndroidNativeEGL setting and its
developer-tools checkbox.
- displayInit/displayRender, and with them the "Second time, joining the
emuthread and starting it up again" dance - restarting the emu thread from
inside a JNI callback because a lost context was only observable as a
second onSurfaceCreated.
- GraphicsContext::NotifyContextLost, which existed solely because that join
drained the render queue on a thread with no current context. The render
thread now joins the emu thread with the context still current, so the
drain is real work and nothing has to be skipped.
- g_emuThread, now that nothing starts an emu thread outside the render loop.
Three things displayInit/displayRender did that nothing else did, moved
rather than dropped:
- EnterVR and the per-frame StartVRRender/UpdateVRInput/FinishVRRender hooks
now live in RenderLoopThread's GL branch. Java's GL thread could simply
return early and wait for the next vsync when the VR session was inactive;
this loop drives itself, so that case sleeps 16ms instead of spinning.
Not tested - no headset here.
- RECREATE_VIEWS after the emu thread starts, as before. Vulkan never did
this, so it's a candidate for removal when the two paths converge.
- The thin3d error callback, which surfaces GL errors as OSD messages. That
one moved into AndroidEGLGraphicsContext::InitSurface, next to the rest of
the context's own setup, matching WindowsGLContext.
Tested on a nubia Z2464N (Unisoc UMS9632, Mali-G57, Android 15): cold start,
UI, booting a homebrew, backgrounding and resuming both in the menu and
in-game, and a density change, which destroys and recreates the activity the
way a rotation does. Every cycle tears the EGL context down and builds a new
one, and the renderer comes back with FBOs and textures intact. The config
ladder's first choice, RGBA8888 D24S8, is what the Java chooser landed on
here too.

Claude-Session: https://claude.ai/code/session_01152igCdjTNhT29qvphPyPC
First step towards removing JavaGL. The point isn't EGL itself - it's who
owns the render thread. With GLSurfaceView, Java creates the thread and the
context and calls us back, so a lost context is only observable after the
fact as a second onSurfaceCreated. That's what forces displayInit to tear
down and restart the emu thread from inside a JNI callback, and to call
NotifyContextLost first because the queue is about to be drained on a thread
with no context. None of that is needed when we own EGL: the render thread
joins the emu thread itself, with the context still current, so the drain is
real work rather than something to skip.
AndroidEGLGraphicsContext subclasses OpenGLGraphicsContext (whose own
InitSurface assumes someone else already made a context current) and adds
display/config/surface/context plus a swap function. With it, GL reuses the
Vulkan lifecycle wholesale: queryConfig("androidJavaGL") returns false, so
Java builds a plain SurfaceView and starts the native render loop when a
surface arrives - including all of the surface/pause ordering fixes from the
previous branch. runVulkanRenderLoop/requestExitVulkanRenderLoop are now
runRenderLoop/requestExitRenderLoop and serve both backends; the thread they
spawn branches on NeedsSeparateEmuThread, because the two backends split the
work in opposite directions (Vulkan: this thread is the main loop and the
render manager spawns the render thread; GL: this thread *is* the render
thread and spawns the emu thread).
Deliberately a port, not an improvement:
- GLES client version still follows NativeRenderer - 3 for VR, 2 otherwise.
Not a cap; GLES3 is detected from GL_VERSION at runtime.
- No swap-interval function. GLSurfaceView gave us no way to set one, so
PresentMode::IMMEDIATE has always been ignored here, and honoring it now
would be a behavior change. Worth revisiting once this path is the only one.
The config ladder does take the user's word that Mali 400 and the Xperia Play
are no longer a factor: it asks for RGBA8888/D24S8 and falls back twice,
rather than reproducing GLSurfaceView's ask-for-nothing default that the
comments in PpssppActivity.onCreate exist to explain. ANativeWindow's format
is set from EGL_NATIVE_VISUAL_ID, which is the proper fix for the EGL_BAD_MATCH
those comments describe.
Off by default, behind Developer tools / Graphics / "Use native EGL instead
of GLSurfaceView" (OpenGL backend, Android only). Needs an app restart, since
the context is chosen in NativeApp.init.

On a cold start, onCreate passed the intent's shortcut parameter to
NativeApp.init and then also posted it as a "shortcutParam" message, which
is only meant for when the native side is already up. For a game shortcut
the second boot request was rejected with an error. For the Args extra,
the raw command line got booted as if it was a game path, so something
like --loglevel=4 applied fine and then popped up a load failure.

EmuThread_Join drains the render queue on the calling thread. On Android
that is either the UI thread with no GL context (NativeApp.shutdown), or
the GL thread with a brand new context after the old one was lost
(displayInit the second time). The skip flag was only set once the emu
thread reached NativeShutdownGraphics, so everything queued before that
ran for real, against nothing or against the wrong context.
Add GraphicsContext::NotifyContextLost() and call it before the join in
both places. skipGLCalls_ is now atomic, since it's set from one thread
and read from another.

The surface may not be used after surfaceDestroyed returns. We relied on
onPause having joined the thread first, which is the usual order but not a
guaranteed one. When it didn't hold, the thread kept spinning on a lost
surface, and the replacement surface was refused as "Already running".
Also forget a surface deferred while paused if it gets destroyed before
the resume that would have used it.

If InitSurface failed, the thread returned but stayed joinable, so the next
surface was refused as "Already running" until the next pause. Tell a live
thread from a finished one with renderLoopRunning, and reap the latter.
Also make VulkanGraphicsContext::InitSurface clean up when it fails after
creating the draw context. Callers don't call ShutdownSurface on failure,
so draw_ (with its render manager) and the surface leaked, and the next
attempt overwrote the pointer.

requestExitVulkanRenderLoop went by renderLoopRunning, which the thread
only set once it got going. A pause landing between thread creation and
that point returned without signalling or joining, leaving a render thread
running while paused, and every later start refused as "Already running".
Go by whether there is a thread to join instead, set the running flag
before the thread is created, and let the requester reset exitRenderLoop
after the join rather than the thread itself.
