OHOS App Build & Debug
When to Use This Skill
Use this skill when the user needs to work with HarmonyOS/OpenHarmony applications:
- Building: "Build my OHOS app", "Compile the project", "Run hvigorw"
- Installing: "Install this HAP", "Deploy to device", "Install app to device"
- Launching: "Launch the app", "Start the application", "Run on device"
- Debugging: "Take screenshot", "Parse crash stack", "Debug crash"
- Environment: "Check DevEco Studio", "Show SDK path", "Verify tools", "Detect environment"
Quick Start
Build, install, and launch an OHOS application:
# Run scripts from skill directory
python3 $SKILL_DIR/scripts/build.py
python3 $SKILL_DIR/scripts/install.py -f entry/build/default/outputs/default/entry-default-signed.hap
python3 $SKILL_DIR/scripts/launch.pyBundled Resources
This skill includes executable scripts in scripts/ that automatically detect DevEco Studio environment:
| Script | Purpose |
|---|---|
build.py | Build OHOS application using hvigorw |
install.py | Install HAP file to connected device |
launch.py | Launch installed application |
screenshot.py | Capture device screenshot |
parse_crash.py | Parse crash stack using hstack |
env_detector.py | Detect DevEco Studio and tools |
ohos_utils.py | Shared utility functions |
For detailed command reference, see references/command-reference.md.
Common Workflows
Build and Install
# 1. Check environment
python3 $SKILL_DIR/scripts/env_detector.py
# 2. Build the application
python3 $SKILL_DIR/scripts/build.py
# 3. Install to device (output from build.py shows HAP path)
python3 $SKILL_DIR/scripts/install.py -f entry/build/default/outputs/default/entry-default-signed.hap
# 4. Launch the app
python3 $SKILL_DIR/scripts/launch.pyOne-line Build, Install, Launch
python3 $SKILL_DIR/scripts/build.py && \
python3 $SKILL_DIR/scripts/install.py -f $(find entry/build -name "*.hap" | head -1) && \
python3 $SKILL_DIR/scripts/launch.pyDebug Workflow
# Launch app
python3 $SKILL_DIR/scripts/launch.py
# Take screenshot to verify
python3 $SKILL_DIR/scripts/screenshot.py -o ./screenshotsCrash Analysis
# Parse crash stack from file
python3 $SKILL_DIR/scripts/parse_crash.py -f crash.txt
# Parse from string
python3 $SKILL_DIR/scripts/parse_crash.py -c "stack trace here"How It Works
Automatic Environment Detection
All scripts automatically detect DevEco Studio installation and configure the environment:
- DevEco Studio Detection
- Windows: C:\Program Files\Huawei\DevEco Studio\ - macOS: /Applications/DevEco-Studio.app/ - Linux: ~/DevEco-Studio/ or /opt/DevEco-Studio/
- Toolchain Configuration
- Sets JAVA_HOME to DevEco's bundled JBR - Adds SDK tools to PATH - Configures HDC_SERVER_PORT=7035 - Caches detection result for 24 hours
- Auto-Detected Tools
- Core: hdc, hvigorw, java - LLVM: clang, clang++, lld, llvm-* - Profiler: hiprofiler, hiperf - Other: hstack, ohpm, idl, restool, syscap_tool
Response Guidelines
When helping users with OHOS development:
- Locate Skill Directory
- Replace $SKILL_DIR with the actual skill installation path - Common locations: ~/.claude/skills/ohos-app-build-debug or project-specific paths
- Execute Scripts
- Call Python scripts in scripts/ directory using absolute or relative paths - Always change to the OHOS project directory before running scripts
- Show Environment First
- Run env_detector.py when first building to show tool availability
- Provide One-liners
- Combine build, install, launch when appropriate for user convenience
- Show Actual Commands
- Display the hvigorw/hdc commands being executed for transparency
- Handle Errors Gracefully
- Provide troubleshooting guidance when commands fail - Reference references/troubleshooting.md for detailed help
- Use Project Context
- Auto-detect bundle names and paths from project structure
Error Handling
If DevEco Studio is not detected:
- Verify DevEco Studio is installed
- Check standard installation paths
- Set
DEVECO_STUDIO_PATHenvironment variable
If device is not connected:
- Check USB cable connection
- Verify USB debugging is enabled on device
- Authorize USB debugging on device when prompted
For detailed troubleshooting, see references/troubleshooting.md.
Prerequisites
- DevEco Studio 3.1+ (4.0+ recommended)
- OHOS Device with USB debugging enabled
- Python 3.7+ (for running scripts)
