Pywayne ADB Logcat Reader

This module provides real-time Android device log reading capabilities via the adb logcat command.

Quick Start

from pywayne.adb.logcat_reader import AdbLogcatReader

# Create reader (default C++ backend)
reader = AdbLogcatReader()

# Start log capture and read
reader.start()
for line in reader.read():
    print(line)

Use Python backend (alternative)

reader = AdbLogcatReader(backend='python') reader.start() for line in reader.read(): print(line)

# Stop and cleanup
reader.stop()

Initialization

# C++ backend (default, faster)
reader = AdbLogcatReader()

# Python backend (alternative, may be more compatible)
reader = AdbLogcatReader(backend='python')

Reading Logs

The read() method yields log lines incrementally as a generator, suitable for processing large logs or real-time monitoring.

# Process logs as they arrive
for line in reader.read():
    # Filter, parse, store...

Properties

Property	Description
backend	'cpp' or 'python'
running	Whether logcat process is running

Methods

Method	Description
start()	Start adb logcat process
read()	Generator yielding log lines
stop()	Stop logcat process
get_backend()	Get active backend type

Backends

C++ Backend (Default)

• Uses native C++ implementation
• Faster performance for real-time streaming
• Better compatibility with adb logcat

Python Backend (Alternative)

• Uses Python subprocess to call adb
• More compatible across different environments
• Easier debugging and integration

Notes

• C++ backend is faster and recommended for production
• Python backend may be useful during development
• stop() terminates adb logcat; use Ctrl+C to send interrupt signal
• Logs are cleared automatically when process stops
