Use this skill to generate well-branded interfaces and assets for RIPDPI (an Android-native, Compose-first VPN and DPI-bypass app), either for production or throwaway prototypes/mocks/etc. Contains essential design guidelines, colors, type, fonts, brand-ship icons, and an interactive UI kit of every public composable from the live ui/components tree.

rust-android-build

po4yka/RIPDPI

Android-specific Rust build, verification, and packaging — per-target 16 KiB page alignment, size-optimized release profile, ELF symbol allowlist, .so size budgets, NDK 29 specifics. Use when modifying .cargo/config.toml for Android targets, the workspace [profile.release] / [profile.android-jni] block, or when verifying a built .so before release.

rust-android-telemetry

po4yka/RIPDPI

Telemetry and observability discipline for the RIPDPI Android Rust stack — control-plane vs data-plane logging, bounded flume event queues, atomic counters, snapshot polling, readiness callbacks, and deterministic JSON contracts. Use when authoring or modifying telemetry emission code, the bounded event ring, the Kotlin-side telemetry consumer, or any per-packet logging.

Android Device Debug

ADB-based debugging for the RIPDPI app on physical devices and emulators. No third-party tools -- uses only adb, Gradle, and existing repo scripts.

Full test stack documentation: docs/testing.md. Do not duplicate it here -- read it when you need runner details, CI lanes, or fixture locations.

Device Discovery & Connection

adb devices -l                        # list connected devices/emulators
adb wait-for-device                   # block until a device is available

Multi-device disambiguation:

export ANDROID_SERIAL=<serial>        # all subsequent adb commands target this device
adb -s <serial> <command>             # one-off targeting

Build, Install & Launch

Build

# Physical device (ARM)
./gradlew assembleDebug -Pripdpi.localNativeAbis=arm64-v8a

# Emulator (x86_64 -- fast path)
./gradlew assembleDebug -Pripdpi.localNativeAbis=x86_64

Install

adb install -r app/build/outputs/apk/debug/app-debug.apk

Launch with Automation Extras

Source of truth: app/src/main/kotlin/com/poyka/ripdpi/automation/AutomationLaunchContract.kt

adb shell am start -n com.poyka.ripdpi/.activities.MainActivity \
  --ez com.poyka.ripdpi.automation.ENABLED true \
  --ez com.poyka.ripdpi.automation.RESET_STATE true \
  --ez com.poyka.ripdpi.automation.DISABLE_MOTION true \
  --es com.poyka.ripdpi.automation.START_ROUTE home \
  --es com.poyka.ripdpi.automation.PERMISSION_PRESET granted \
  --es com.poyka.ripdpi.automation.SERVICE_PRESET idle \
  --es com.poyka.ripdpi.automation.DATA_PRESET clean_home

Deep link equivalent:

adb shell am start -a android.intent.action.VIEW \
  -d "ripdpi-debug://automation/launch?enabled=true&reset_state=true&start_route=home"

Automation Preset Values

Extra	Values
`PERMISSION_PRESET`	`granted`, `notifications_missing`, `vpn_missing`, `battery_review`
`SERVICE_PRESET`	`idle`, `connected_proxy`, `connected_vpn`, `live`
`DATA_PRESET`	`clean_home`, `settings_ready`, `diagnostics_demo`

Route source of truth: app/src/main/kotlin/com/poyka/ripdpi/ui/navigation/Route.kt

Logcat Filtering

Native logcat tags (from Rust source):

Tag	Source
`ripdpi-native`	Proxy engine + diagnostics (`ripdpi-android` crate)
`ripdpi-tunnel-native`	VPN tunnel (`ripdpi-tunnel-android` crate)

# Native layer only
adb logcat -s ripdpi-native:V ripdpi-tunnel-native:V

# App process only (all tags)
adb logcat --pid=$(adb shell pidof com.poyka.ripdpi)

# Broad filter
adb logcat | grep -i ripdpi

# Crash buffer
adb logcat -b crash -d

# Clear buffer, then reproduce and capture
adb logcat -c
# ... reproduce the issue ...
adb logcat -d > android-logcat.txt

Port Forwarding for Local Network Fixture

The fixture exposes TCP/UDP/TLS echo, DNS responders, DoH, SOCKS5 relay, and fault injection.

# Start fixture on host
bash scripts/ci/start-local-network-fixture.sh

# Forward ports to device
adb reverse tcp:46090 tcp:46090   # control/health
adb reverse tcp:46001 tcp:46001   # TCP echo
adb reverse tcp:46003 tcp:46003   # TLS echo
adb reverse tcp:46053 tcp:46053   # DNS
adb reverse tcp:46054 tcp:46054   # DNS secondary

# Verify
curl -fsS http://127.0.0.1:46090/health
curl -fsS http://127.0.0.1:46090/manifest | jq .
adb reverse --list

Stop: bash scripts/ci/stop-local-network-fixture.sh

For physical devices set RIPDPI_FIXTURE_ANDROID_HOST=127.0.0.1 before starting the fixture.

Instrumented Tests on Device

# Full suite
./gradlew :app:connectedDebugAndroidTest -Pripdpi.localNativeAbis=arm64-v8a

# Integration tests only
./gradlew :app:connectedDebugAndroidTest -Pripdpi.localNativeAbis=arm64-v8a \
  -Pandroid.testInstrumentationRunnerArguments.package=com.poyka.ripdpi.integration

# E2E tests only
./gradlew :app:connectedDebugAndroidTest -Pripdpi.localNativeAbis=arm64-v8a \
  -Pandroid.testInstrumentationRunnerArguments.package=com.poyka.ripdpi.e2e

# Single test class
./gradlew :app:connectedDebugAndroidTest -Pripdpi.localNativeAbis=arm64-v8a \
  -Pandroid.testInstrumentationRunnerArguments.class=com.poyka.ripdpi.e2e.NativeTelemetryGoldenSmokeTest

# Maestro smoke flows
bash scripts/ci/run-maestro-smoke.sh

# Coverage report
./gradlew :app:createDebugAndroidTestCoverageReport -Pripdpi.localNativeAbis=x86_64

Use -Pripdpi.localNativeAbis=x86_64 for emulator, arm64-v8a for physical device.

Screenshot & Screen Recording

# Screenshot
adb exec-out screencap -p > screenshot.png

# Screen recording (Ctrl+C to stop, max 3 min)
adb shell screenrecord /sdcard/recording.mp4
adb pull /sdcard/recording.mp4 .
adb shell rm /sdcard/recording.mp4

App State Inspection

# Package info (permissions, components, version)
adb shell dumpsys package com.poyka.ripdpi

# Running services
adb shell dumpsys activity services com.poyka.ripdpi

# VPN and network state
adb shell dumpsys connectivity

# DataStore / shared prefs
adb shell run-as com.poyka.ripdpi ls shared_prefs/

# App ops (battery optimization, etc.)
adb shell cmd appops get com.poyka.ripdpi

# Force stop
adb shell am force-stop com.poyka.ripdpi

# Clear all app data
adb shell pm clear com.poyka.ripdpi

Network Debugging

# Check VPN tunnel interface
adb shell ip addr show tun0

# Routing table (all tables -- VPN creates its own)
adb shell ip route show table all

# Listening sockets (proxy port)
adb shell ss -tlnp

# Active reverse forwards
adb reverse --list

# Remove all reverse forwards
adb reverse --remove-all

# DNS resolution
adb shell nslookup example.com

Crash & ANR Debugging

Java/Kotlin Crash

adb logcat -b crash -d
adb shell dumpsys dropbox --print | grep -A 20 data_app_crash

Native Crash (Rust)

# Tombstone summary
adb logcat -s DEBUG:E

# Full tombstone files (may need root)
adb shell ls /data/tombstones/

# Complete bug report
adb bugreport bugreport.zip

Symbolicate with NDK addr2line:

$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/*/bin/llvm-addr2line \
  -e native/rust/target/<triple>/debug/libripdpi.so <address>

Debug .so files with symbols are under native/rust/target/<triple>/debug/. The stripped copies in core/engine/build/generated/jniLibs/ lack symbols.

ANR

# Main thread state
adb shell dumpsys activity processes com.poyka.ripdpi

# ANR traces (may need root)
adb pull /data/anr/traces.txt

Common RIPDPI ANR cause: JNI call blocking the main thread. The proxy jniStart is intentionally blocking -- see native-jni-development skill.

Emulator Management

CI uses API 34, x86_64, google_apis, default profile. Match for CI parity.

# List existing AVDs
emulator -list-avds

# Download system image (if needed)
sdkmanager "system-images;android-34;google_apis;x86_64"

# Create CI-parity AVD
avdmanager create avd -n ripdpi-debug \
  -k "system-images;android-34;google_apis;x86_64" -d default

# Start with GUI
emulator -avd ripdpi-debug -gpu host

# Start headless (CI style)
emulator -avd ripdpi-debug -no-window -noaudio -no-boot-anim -gpu swiftshader_indirect

# Cold boot (no snapshot)
emulator -avd ripdpi-debug -no-snapshot-load

# Delete AVD
avdmanager delete avd -n ripdpi-debug
