# Custom output location
sandroid --config <(echo 'paths.results_path="/tmp/analysis"')

Debugging and Troubleshooting

Debug Mode:

sandroid --loglevel DEBUG --network

Verbose Output:

SANDROID_LOG_LEVEL=DEBUG sandroid --network 2>&1 | tee analysis.log

Common Issues

  1. Device not found:

    # Check ADB connection

    adb devices sandroid –loglevel DEBUG

  2. Permission errors:

    # Ensure device is rooted

    adb shell su -c ‘id’

  3. Frida issues:

    # Test Frida separately

    frida-ps -U

  4. Configuration problems:

    # Validate configuration

    sandroid-config validate

Log Analysis:

# Find specific errors
grep -i error ~/.cache/sandroid/logs/sandroid.log

# Monitor real-time
tail -f ~/.cache/sandroid/logs/sandroid.log

Integration Examples

Best Practices

  1. Always use multiple runs (--number 2 minimum) for accurate change detection

  2. Enable network monitoring (--network) for comprehensive analysis

  3. Use configuration files for consistent analysis parameters

  4. Archive results in structured directories with timestamps

  5. Monitor resource usage during analysis to avoid system overload

  6. Validate configurations before batch processing

  7. Use appropriate log levels for your use case (INFO for production, DEBUG for troubleshooting)
