esefxdzandClaude Opus 5 9d67679fa8 fix(app): do not throw from ConnectionSettings.initialize
The migration write is best-effort again. `_mode` is already the safe TUN
default in memory by the time it runs, so a failed write leaves nothing
insecure -- it only means the migration is retried on the next launch.

Throwing there was a startup brick rather than a fail-closed guard.
`initialize()` is awaited from `main()` at lib/main.dart:19, before
`runApp()`, with no try/catch and no `runZonedGuarded`; `FlutterError.onError`
and `PlatformDispatcher.onError` are installed later and would not catch it
either. The branch also runs on every fresh install, since `storedMode` is null
and `null != 'tun'`. A `setString` returning false would therefore have meant a
black screen with no error UI, repeating every launch, in exchange for no
security benefit.

Also restores two comments this PR removed from code it does not otherwise
touch -- the `_reconnect` note on why the repair path shows no rewarded ad, and
the explanation of how an orphaned proxy outlives the app process -- and drops
a stray 'ass' from the legacy-values comment.

The `setMode` half of the PR is unchanged: persisting before mutating memory
and surfacing failures to the UI is the right behaviour.

esefxdzandClaude Opus 5 bd41a3c693 refactor(app): drop Dart wrappers whose native handlers no longer exist
#17 removed the `setSessionExpiry` and `isVpnRuntimeAlive` MethodChannel
handlers from MainActivity, and #18 removed their last callers. The Dart
wrappers stayed behind.

Both swallow their errors, so a future caller would not fail loudly — it would
get a silent no-op from `setSessionExpiry` and a permanent
`processAlive: false` from `runtimeState()`, which previously read as "the
tunnel is dead". Deleting them keeps that trap out of the codebase.

`VpnRuntimeState` goes with them; runtime liveness now arrives through the
native status stream, which is generation-scoped. The battery-optimisation
methods are untouched and still used by background_reliability.dart.

esefxdzandClaude Opus 5 061bd41920 Merge pull request #19 from Naveax/pr/add-android-supply-chain-ci
build: add reproducible Android release verification

Resolved a conflict in android/app/build.gradle.kts. #19 was written against
the pre-#10 file and re-added the pub-cache patch tasks that #10 deleted; only
`sha256Hex()` was kept from that block, since `verifyReleaseAppConfig` needs it.

Also restored `import java.io.File`, which #10 removed along with the patch
tasks. #19's `sha256Hex(file: File)` names the type in its signature, and
Kotlin does not auto-import `java.io.File`, so the release build would have
failed at Gradle configuration without it.

Verified after resolution: no orphaned references to `projectRootDir`,
`localProperties`, `flutterSdkPath` or `patchFlutterVless`; both tests in
test/release_verification_regression_test.dart pass; `flutter analyze` reports
no errors or warnings.

esefxdzandClaude Opus 5 e818d54b0e build(config): delete orphaned assets instead of narrowing the manifest
#16 replaced the `assets/` wildcard with three explicit paths. That is correct
today but makes the failure mode for a forgotten registration an `Unable to load
asset` exception at runtime rather than at build time, which neither
`flutter analyze` nor the build would catch.

Restore the wildcard and delete the three files it was working around instead.
All are unreferenced in tracked source: `logo.png` has no callers and no
`flutter_launcher_icons` config, while `notification_icon.png` and
`notification_banner.png` are stale copies of the real Android drawables in
`android/app/src/main/res/`, which the notification reaches via
`R.drawable.notification_status_icon` and never through the Flutter bundle.

Same APK-size win, no hand-maintained list, and the dead files leave the repo.

esefxdzandClaude Opus 5 dfeb7f161c fix(app): resume the session clock when attaching to a live tunnel
The clock sat at 00:00:00 on a connected tunnel, and the notification
countdown froze with it.

SessionTimer is built lazily, so when the app reattaches to a tunnel that
outlived its UI process, VpnConnection had already reported CONNECTED
before the timer existed. A change listener does not replay events it was
not present for, so the timer never learned it should be running. The
notification text is pushed by that same timer, which is why the countdown
froze at the same moment -- one cause, both symptoms.

The timer now evaluates the current connection state once at construction
rather than waiting for a transition, and is created eagerly alongside
VpnConnection so it is listening from the start.

Resuming also no longer requires adoptedRunningRuntime or a previous
successful sync. Both are false in a freshly started process, which is
exactly the case that needed to work. A connected tunnel with a stopped
clock is now always resumed.

Version 3.3.3+29.

esefxdzandClaude Opus 5 186dc906da feat(app): keep the tunnel alive via the OS, drop the workarounds
3.3.1 could display "connected" against a tunnel that was no longer
running, with a frozen countdown and no traffic. Three causes, and the
fix for each removes more code than it adds.

Liveness was read from getConnectedServerDelay(), which measures through
AppConfigs.V2RAY_CONFIG?.LOCAL_SOCKS5_PORT ?: 10807. AppConfigs lives in
the :RunSoLibXrayDaemon process, so from the UI process it is always null
and the port always fell back to 10807 -- accidentally correct while the
SOCKS port was fixed, permanently wrong once 3.3.1 made it ephemeral.
Liveness now comes from the OS: is our service process running, and is a
VPN transport actually present.

The foreground notification (id 1) is owned by XrayVPNService via
startForeground, but MainActivity was posting to the same id from the UI
process. When that process died its notification stayed on screen with
nothing left to update it. MainActivity now refuses to post for a dead
runtime and clears the stale notification instead.

Nothing ever asked Android for permission to stay alive. Adds the
battery-optimisation exemption prompt and a deep link to Always-on VPN --
the two sanctioned mechanisms for background survival, each needing one
user tap.

Removes Standard/Extreme resilience and the runtime-restart machinery:
recovery ran off a disconnect broadcast delivered to the app process, so
it could never fire when Android killed that process. Removes startup
restoration and the config-snapshot rebuild along with it; with the OS
keeping the tunnel up there is nothing to restore.

Version 3.3.2+28.

## [3.3.6] — 2026-10-08
### Fixed
- **VPN service notification icon.** The ongoing notification now uses the
bundled `notification_icon` drawable instead of `notification_status_icon`,
and the vendored runtime resolves that drawable by name at runtime (falling
back to the platform icon only if it is missing), so the foreground-service
notification no longer shows the generic Android info icon.
- **"Test Local SOCKS" no longer claims an outbound it never tested.** Xray
answers a SOCKS `CONNECT` before it dials upstream, so trusting the `0x00`
reply reported success for unroutable addresses and for hostnames that can
never resolve — meaning the test said OK while the server was down, which is
exactly when it gets run. It now forces a request/response round trip through
the tunnel and reports distinctly when the outbound never replies, drops the
connection, or returns unexpected data.
---
## [3.3.5] — 2026-09-06
### Added
- **Reproducible release verification.** The release build pins the production
`app_config.dart` by SHA-256 and fails closed on any mismatch, so a release
APK cannot silently ship a template or wrong server config.
### Changed
- **Vendored Android runtime.** The pinned `flutter_vless` Android runtime is now
vendored in-tree instead of being patched in the pub cache at build time.
- **Harden the control-plane trust boundary.** `/session/status` fields are
strictly validated (nonce, destination IP, port, SNI, XHTTP path), control
responses are capped and never follow redirects, and the tunnel destination
is pinned to the compiled server — a compromised API can no longer redirect
user traffic.
- **Authenticated local SOCKS5 is now mandatory.** The ephemeral local proxy
replaces rather than filters inbounds, so only the authenticated SOCKS5
listener can exist.
- **Fail closed on connection-mode changes.** The mode is persisted before it is
applied, and a failed save leaves the UI and runtime unchanged instead of
silently selecting a weaker route.
### Fixed
- Connect button no longer leaks a listener into a disposed `AnimationController`
during teardown.
- Disclosure acknowledgement is only persisted once the user accepts it.
- Session countdown now uses a monotonic clock (cannot be extended by rolling the
device clock back) and a VPN error tears the tunnel down instead of freezing
the timer on a live session.
- The VPN-service notification's disconnect action and countdown re-post are
aligned with the vendored runtime.
### Removed
- Unsupported server-selector UI (single server today; design retained for
multi-server later).
- Unused Flutter dependencies and orphaned assets.
- Dead Dart wrappers whose native handlers no longer exist.
### Security & privacy
- IPv6 is captured by the VPN interface (`::/0` route), closing a leak where
IPv6 traffic could bypass the tunnel on IPv6-capable carriers.
---
## [3.3.4] — 2026-09-02
### Added
- **OS-level session-expiry enforcement.** The VPN service now holds an absolute
deadline and tears the tunnel down on its own clock — a main-looper handler
plus an `AlarmManager` exact alarm (falling back to an inexact alarm on
Android 13+ when exact alarms aren't granted). The app pushes
`now + expires_in_seconds` on each session sync, so a session ends even if the
UI process has been killed.
- **Session survival across process death.** The service persists the active
session and re-establishes it when Android restarts it (`START_STICKY`).
- **Support-ad extension reflected immediately.** A rewarded "Support us" ad now
forces an immediate server sync, so the countdown and expiry deadline update
without waiting for the next heartbeat.
### Changed
- **Session-status beacon slowed.** Foreground poll: 5 s → 60 s; background poll:
30 s → 60 s.
- **Background-reliability guidance.** The "Always-on VPN" settings deep-link was
removed; the battery-optimisation exemption remains, with expiry now enforced
by the service itself.
### Removed
- Legacy `ass` connection-mode migration — unrecognized persisted modes now
default to TUN.
### Security & privacy
- Session credentials and the per-user VLESS UUID are now held app-private on
disk (`active_session.bin`) for the session's lifetime and removed on
disconnect or expiry. Previously they were memory-only.
---
## [3.3.3] — 2026-09-01
### Fixed
- **The session clock stayed at 00:00:00 on a live tunnel, and the notification
countdown froze with it.** `SessionTimer` is built lazily, so when the app reattaches
to a tunnel that outlived its UI process, `VpnConnection` had already reported
"connected" before the timer existed — and a change listener does not replay events
it was not present for. The timer now evaluates the current connection state once at
construction instead of waiting for a transition, and is created eagerly alongside
`VpnConnection`. Because the timer is what pushes text to the foreground
notification, a stopped clock also meant a frozen countdown; both come from this.
- Resuming the clock no longer requires `adoptedRunningRuntime` or a previous
successful sync, both of which are false in a freshly started process. A connected
tunnel with a stopped clock is now always treated as something to resume.
## [3.3.2] — 2026-09-01
Background reliability. 3.3.1 could show "connected" against a tunnel that was no
longer running; this release fixes the cause rather than the symptom, and removes the
machinery that existed to work around it.
### Added
- **Background reliability settings.** Android stops background services of apps that
are not exempt from Doze, and tears down the process group when a task is swiped
away. Two OS mechanisms prevent that, and the app now surfaces both: a one-tap
**battery optimisation exemption**, and a deep link to Android's **Always-on VPN**
settings (with a note about "Block connections without VPN"). Neither can be enabled
programmatically — each needs a single user tap, once.
### Fixed
- **The app could report "connected" with no traffic flowing.** Startup state came from
`getConnectedServerDelay()`, which measures through
`AppConfigs.V2RAY_CONFIG?.LOCAL_SOCKS5_PORT ?: 10807`. `AppConfigs` lives in the VPN's
own process, so from the UI process it is always null and the port always fell back to
10807. That was accidentally correct while the SOCKS port was fixed; 3.3.1's
per-session ephemeral ports made it permanently wrong. Liveness is now determined from
the OS — whether our VPN service process is running, and whether a VPN transport is
actually present.
- **A frozen countdown could outlive the tunnel.** The foreground notification (id 1) is
owned by the VPN service via `startForeground`, but the UI process was posting to the
same id. When that process died, its notification stayed on screen with nothing left to
update it. The app no longer posts for a runtime that is not alive, and clears a stale
notification instead.
### Removed
- **Standard/Extreme resilience modes** and the runtime-restart machinery behind them.
Recovery ran off a disconnect broadcast delivered to the app process, so it could never
fire in the case that actually matters — Android killing that process. It was
complexity substituting for background persistence.
- **Startup restoration**, including the config-snapshot rebuild. With the tunnel kept
alive by the OS, there is nothing to restore; the app simply reports what is running.
- The `resilience_mode` preference and its settings tile.

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.

## 1.1.5
* Updated the Android runtime dependency to `dev.tfox.fluttervless:xray-android:26.7.11`.
* Rebuilt Android `libxray.so` binaries for `armeabi-v7a`, `arm64-v8a`, `x86`, and `x86_64` against Xray-core `v26.7.11`.
* Fixed Android VPN app routing: all configured blocked apps are now applied to `VpnService.Builder` as disallowed applications and bypass the Xray VPN tunnel.
## 1.1.4
* Updated the Android runtime dependency to `dev.tfox.fluttervless:xray-android:26.6.27.1`.
* Rebuilt Android `libxray.so` binaries for `armeabi-v7a`, `arm64-v8a`, `x86`, and `x86_64` against Xray-core `v26.6.27`.
## 1.1.3
* Updated the Android runtime dependency to `dev.tfox.fluttervless:xray-android:26.6.22`.
* Rebuilt Android `libxray.so` binaries for `armeabi-v7a`, `arm64-v8a`, `x86`, and `x86_64` against Xray-core `v26.6.22`.
## 1.1.2
* Clarified that Android device and emulator runtime binaries are delivered through the main Maven `xray-android` AAR.
* Kept the Android runtime dependency on `dev.tfox.fluttervless:xray-android:26.6.1.1`.
## 1.1.1
* Updated the Android device runtime `libxray.so` binaries to Xray-core `v26.6.1`.
* Kept Android 15+ 16KB page-size linker alignment for the rebuilt ARM binaries.
* Moved Android runtime binaries and geodata into the Maven `dev.tfox.fluttervless:xray-android:26.6.1.1` AAR dependency.
* Included device and emulator ABIs (`armeabi-v7a`, `arm64-v8a`, `x86`, `x86_64`) in the main Maven runtime AAR.
* Removed raw device `jniLibs` and geodata files from the Pub.dev wrapper package; the wrapper now resolves the runtime from Maven Central.
## 1.1.0
* Replaced Android Dart boilerplate with the shared `VlessMethodChannelAdapter`.
* Removed template `getPlatformVersion` scaffold files.
* Moved `flutter_lints` to `dev_dependencies`.
* Removed publish-time dependency overrides from `pubspec.yaml`.
## 1.0.2
* XRay version up
## 1.0.1
* XRay version up
## 1.0.0
* Initial release of the Android implementation for `flutter_vless`.
* Supports VLESS/VMESS protocols using Xray core.
* Implements `VlessPlatform` interface.

# flutter_vless_android
The Android implementation of the `flutter_vless` plugin.
## Runtime
Android runtime binaries and geodata are delivered through the Maven Central AAR dependency `dev.tfox.fluttervless:xray-android:26.7.11`. This keeps the Pub.dev package lightweight while preserving the same packaged Xray files in the final Android app.
Do not add raw `android/src/main/jniLibs` or geodata files back to this package. Rebuild runtime files in `android_runtime/xray_android/src/main`, publish the Maven AAR, then publish this wrapper package.
## Emulator Support
The current Maven runtime AAR includes `armeabi-v7a`, `arm64-v8a`, `x86`, and `x86_64`.
This covers both physical Android devices and Android emulators.

# Xray & Tun2socks Android Build Guide
This guide explains how to build the native libraries (`libxray.so` and `libtun2socks.so`) for the Flutter Vless plugin.
Android runtime files are stored in `android_runtime/xray_android/src/main` and published as the Maven Central AAR `dev.tfox.fluttervless:xray-android`. They are not stored in the `flutter_vless_android` Pub.dev package.
**Key Features:**
- ✅ **Android 15+ Support**: Builds with 16KB page size alignment.
- ✅ **Socket FD Passing**: `tun2socks` is patched to receive the TUN file descriptor via a Unix socket (bypassing Android process restrictions).
## Prerequisites
1. **Go (Golang)**: Version 1.21+ installed.
2. **Android NDK**: Version r27+ (recommended).
3. **macOS/Linux**: Build scripts are designed for Unix-like environments.
## 1. Environment Setup
Export the path to your Android NDK.
```bash
# Example (Adjust path to your NDK installation)
export ANDROID_NDK_HOME="$HOME/Library/Android/sdk/ndk/27.0.12077973"
```
## 2. Build Xray (`libxray.so`)
This script builds the Xray core for Android device and emulator architectures (`arm64-v8a`, `armeabi-v7a`, `x86`, `x86_64`) by default and writes them to the Maven runtime module.
```bash
cd android
chmod +x build_xray.sh
./build_xray.sh
```
## 3. Build Tun2socks (`libtun2socks.so`)
We use a custom Go-based build script (`build_tun2socks.sh`) instead of the old C-based one. This ensures 16KB page alignment and includes the socket-based FD passing logic.
```bash
cd android
chmod +x build_tun2socks.sh
./build_tun2socks.sh
```
## 4. Verification (16KB Page Size)
To confirm that the libraries are compatible with Android 15+ (16KB page size), check the `LOAD` segment alignment using `llvm-readelf`.
```bash
# Check alignment (should be 0x4000)
$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/darwin-x86_64/bin/llvm-readelf -l ../../../android_runtime/xray_android/src/main/jniLibs/arm64-v8a/libtun2socks.so | grep LOAD | head -1
```
**Expected Output:**
```
LOAD ... 0x4000
```
If you see `0x1000`, it is **NOT** compatible with 16KB devices.
## 5. Package The Maven Runtime AAR
The `flutter_vless_android` Pub.dev package consumes the Android device runtime through the Maven artifact:
```text
dev.tfox.fluttervless:xray-android:26.7.11
```
After rebuilding `libxray.so`, `libtun2socks.so`, or the geodata files in `android_runtime/xray_android/src/main`, build the local Maven repository from the repository root:
```bash
tool/build_android_runtime_maven.sh
```
For local Android wrapper or example builds before Maven Central publication, pass the local repository path:
```bash
cd example/android
./gradlew :app:assembleDebug \
-PflutterVlessAndroidRuntimeRepo="$PWD/../../android_runtime/xray_android/build/repo"
```
To upload the signed bundle to Maven Central, configure the Central Portal and signing environment variables documented in `android_runtime/xray_android/README.md`, then run:
```bash
tool/publish_android_runtime_maven.sh
```
## 6. Troubleshooting
- **"bad file descriptor"**: This means the socket FD passing failed. Ensure `XrayVPNService.kt` is correctly sending the FD to the socket path specified in `-sock-path`.
- **"permission denied"**: Ensure the app has permissions to write to the socket file in its private directory.
