LogLens
Unified mobile device logging for VS Code. Monitor Android and iOS logs side-by-side without context switching.
Overview
LogLens brings native Android and iOS device logging directly into VS Code. Debug mobile applications without switching between multiple tools or opening Logcat/Xcode. View logs from multiple devices simultaneously with intelligent filtering and color-coded severity levels.
Whether you're testing on physical devices or simulators, LogLens streamlines the mobile debugging workflow into a single, focused interface.
Core Features
Android Support
- Real-time logcat streaming with automatic device detection
- Monitor multiple Android devices and AVDs simultaneously
- Filter by log level (Verbose, Debug, Info, Warning, Error), tag, process, or custom keywords
- Support for multiple buffer types (main, system, radio, events, crash)
iOS Support
- Direct iOS Simulator log monitoring with live updates
- Multi-simulator support for parallel testing
- Application-specific log filtering
- Native Xcode integration
Developer Workflow
- Side-by-side Android and iOS log panels for cross-platform development
- Color-coded log levels for instant visual identification
- Zero context switching—stay in VS Code throughout debugging sessions
- Lightweight implementation with minimal performance overhead
Getting Started
Requirements
Android Development
- ADB (Android Debug Bridge) in your PATH
- USB debugging enabled on connected devices
- Android SDK tools installed
iOS Development
- Xcode with command line tools (
xcode-select --install)
- Running iOS Simulator instance
- macOS system
Installation
- Install LogLens from the VS Code Marketplace
- Open the Mobile Logs panel (look for the panel icon in VS Code's sidebar)
- Connect your devices and start monitoring
No additional configuration needed—the extension auto-detects your development environment.
Usage
Android Logs
- Select a connected device or running AVD
- Choose your desired log level filter
- Optionally select a specific buffer (main, system, radio, events, crash)
- Use the search field to find specific log entries by tag, process name, or content
- Start monitoring with the play button; pause/stop as needed
iOS Logs
- Select a booted iOS Simulator from the dropdown
- (Optional) Filter logs to a specific app bundle identifier
- Monitor streaming simulator output in real-time
- Use search to narrow results
Troubleshooting
Android device not detected?
- Verify
adb devices shows your device
- Enable USB debugging in device settings
- Try the "Refresh device list" command
iOS Simulator not appearing?
- Ensure Xcode is installed and simulator is running
- Verify command line tools:
xcode-select --install
- Restart VS Code if simulator was launched after extension load
Logs not appearing?
- Confirm the app is running and generating output
- Try different log level filters
- Check device authorization/permissions
