esefxdzandClaude Opus 5 f26c459f6c 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.

## [Unreleased]
### Removed
- **The background server check while disconnected.** The app no longer contacts
the server every 30 seconds while you are not connected to it. Nothing about
the connected session changes.
### Changed
- **The status bar no longer guesses whether the server is up.** It reads
"Ready" while disconnected and shows "Online" once a session has synced, so a
green dot now means a session that is actually working rather than a
reachability check made beforehand.
## [3.3.8] — 2026-10-17
### Changed
- **Reconnecting always starts a fresh session.** In SOCKS5 mode, the
**Reconnect** button used to re-attach to the session you already had. It now
ends that session and starts a new one, exactly as the connect button does —
one way to begin a session instead of two, and you get a full window back
rather than the remainder of a broken one.
### Fixed
- **SOCKS5 "Reconnect" works again.** In 3.3.7 it ended your session and then
asked for the session it had just ended, failing with "Session not activated".
---
## [3.3.7] — 2026-10-17
> **Known issue — fixed in 3.3.8.** In SOCKS5 mode, the **Reconnect**
> button in Settings ends your session instead of re-attaching to it, and then
> fails with "Session not activated". It only appears when a proxy session has
> been orphaned, and you lose the rest of that session rather than anything
> worse. Workaround: connect again from the main screen. The "SOCKS5 Reconnect"
> entry below describes the intended behaviour, which this build does not have.
### Added
- **A warning before a session ends.** The VPN service schedules it off the same
deadline it already enforces, so it arrives even with the app closed, and a
support top-up moves it with the deadline. It does not promise an exact number
of minutes: on a deeply sleeping phone Android can hold it back past the end
of the session, in which case it is skipped rather than shown late.
- **A "disconnected — not protected" notification** when a session ends without
you asking: the 2-hour expiry, the data limit, or the server ending the
session.
- **SOCKS5 mode now asks for the notification permission.** It never did,
because it never raises the VPN consent dialog, so on Android 13+ these
alerts would have been dropped before they were shown.
- **The app now shows what went wrong.** Connect errors, the reason a session
ended, and progress while connecting appear under the status bar instead of
the button silently going back to idle.
### Changed
- **A control-plane outage no longer tears down a working tunnel.** The app used
to disconnect itself after about two minutes of failed status polls, putting
you back on your real IP; it now keeps the tunnel up and shows
"Can't reach the server — still connected". Expiry is still enforced by the
VPN service's own deadline, which keeps running regardless.
### Fixed
- **The countdown no longer over-reports after the phone sleeps**, and a clock
moved backwards can no longer stretch a session.
- **A session that expired while the phone was asleep is recognised on waking**,
by wall clock rather than by time the device spent awake.
- **Disconnecting from Android's VPN settings no longer leaves a countdown in
the notification shade.** It used to sit there frozen, showing time remaining
on a tunnel that was already gone.
- **The VPN recovers after the tunnel core stops.** Recovery never worked:
every attempt failed on the same internal error, and each one left another
copy of the core running in the background. It now usually comes back on the
first retry, without dropping the connection.
- **Disconnecting with the app's own button now releases your session on the
server** instead of leaving it open until it expires.
- **SOCKS5 "Reconnect" re-attaches to the current session** instead of
requesting a new one — see the known issue above; this does not work in 3.3.7.
- **A core that fails to start now logs why.** Its output was being discarded,
so the only trace was an exit code.
### Groundwork
- **Rewarded-ad plumbing.** Ads are switched off in this build, so none of this
is reachable yet: the ad's verification nonce is now carried through to the
connect call rather than being minted twice, and the client waits longer
(~36 s) for Google's callback. Reviewed, not yet exercised end to end.
## [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.

# 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

* 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.

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.
