Mopro device

Skill zkmopro/mopro-ai/skills/mopro-device

Manage iOS simulators, Android emulators, and physical devices for testing mopro apps. Use whenever someone wants to list, start, or run on a simulator or emulator, deploy to a phone, or troubleshoot device issues. Also use when a user says "run my app" or "test on device" even if they don't mention simulators explicitly.From its SKILL.md

Mopro Device Management

This skill helps users manage simulators, emulators, and physical devices for testing mopro apps.

When to Use

User wants to run their app on a simulator/emulator
User needs to list available devices
User asks about deploying to a physical device
User encounters simulator/emulator issues

Actions

List Devices

Show all available simulators, emulators, and connected physical devices.

Run the unified device listing script:

bash scripts/list-devices.sh

Run from the skill directory. The script outputs a JSON array to parse and present.

Or check platforms individually:

# iOS simulators
xcrun simctl list devices available

# Android emulators
$ANDROID_HOME/emulator/emulator -list-avds

# Connected physical devices (Android)
adb devices

# Flutter devices
flutter devices

Start Simulator/Emulator

Before starting, confirm with the user:

About to boot <device_name>. This may take a moment. Proceed?

iOS Simulator:

# List available simulators
xcrun simctl list devices available

# Boot a specific simulator (non-blocking)
xcrun simctl boot "iPhone 16"

After booting, verify the simulator is ready:

xcrun simctl list devices booted

Do NOT use open -a Simulator — it blocks the agent indefinitely. Use xcrun simctl boot instead, which returns immediately.

Android Emulator:

# List available AVDs
$ANDROID_HOME/emulator/emulator -list-avds

Start the emulator using run_in_background=true (do NOT use shell &):

$ANDROID_HOME/emulator/emulator -avd <avd_name>

After starting, verify the emulator is ready:

adb wait-for-device
adb shell getprop sys.boot_completed
# Returns "1" when fully booted

If no AVD exists, guide the user to create one in Android Studio: Tools > Device Manager > Create Device.

Run App on Device

iOS (Xcode):

# Build and run on simulator
xcodebuild -project MyApp.xcodeproj \
    -scheme MyApp \
    -destination 'platform=iOS Simulator,name=iPhone 16' \
    build

# Or open in Xcode and press Cmd+R
open MyApp.xcodeproj

Android (Gradle):

# Install and run on connected device/emulator
./gradlew installDebug
adb shell am start -n com.example.myapp/.MainActivity

Flutter:

flutter run                     # Auto-selects device
flutter run -d <device_id>      # Specific device
flutter run -d chrome            # Web

React Native:

npm run ios          # iOS simulator
npm run android      # Android emulator

Deploy to Physical Device

iOS Physical Device:

Connect device via USB or WiFi
Open project in Xcode
Select the device from the device dropdown
Configure signing: Signing & Capabilities > Team
Build and run (Cmd+R)

Android Physical Device:

Enable Developer Options on the device
Enable USB Debugging
Connect via USB
Verify connection: adb devices
Install: ./gradlew installDebug or flutter run

Troubleshooting

"No devices found"

iOS: Check Xcode is installed, simulators are downloaded
Android: Verify ANDROID_HOME is set, emulator images are installed
Physical: Check USB connection, USB debugging enabled

"Unable to boot simulator"

# Reset a stuck simulator
xcrun simctl shutdown all
xcrun simctl erase all  # WARNING: erases all simulator data

"emulator: command not found"

Add Android emulator to PATH:

export PATH="$PATH:$ANDROID_HOME/emulator"

"adb: command not found"

Add platform-tools to PATH:

export PATH="$PATH:$ANDROID_HOME/platform-tools"

Slow emulator

Enable hardware acceleration (HAXM on Intel, Hypervisor on ARM)
Use x86_64 system images for Android emulator
Allocate more RAM to the emulator in AVD settings

iOS app crashes on device but works on simulator

Check architecture: device needs aarch64-apple-ios, simulator needs aarch64-apple-ios-sim
Check signing configuration
Check that circuit assets are in the app bundle
