# Advanced ADB Logcat Monitor for Android apps
|
||||
#
|
||||
# Author: Reza Esmaeili
|
||||
# Description:
|
||||
# Tail logcat for a specific Android app process (by package) with:
|
||||
# - Device selection (auto or explicit)
|
||||
# - Configurable filters / logcat args
|
||||
# - Optional app restart
|
||||
# - Safe cleanup on exit
|
||||
# - Log files with timestamps in a dedicated directory
|
||||
#
|
||||
# Usage:
|
||||
# ./adb-log-monitor.sh [options] [LOGCAT_FILTER...]
|
||||
#
|
||||
# Examples:
|
||||
# ./adb-log-monitor.sh
|
||||
# ./adb-log-monitor.sh -p ir.avaair.avaair -a avaair -f '*:E'
|
||||
# ./adb-log-monitor.sh -d emulator-5554 --no-restart
|
||||
#
|
||||
# Options:
|
||||
# -p PACKAGE Android package name (default: ir.avaair.avaair)
|
||||
# -a APP_NAME Logical app name used for messages & filenames (default: derived from package)
|
||||
# -d DEVICE Device ID (adb serial). If omitted, will prompt if multiple devices.
|
||||
# -o DIR Logs output directory (default: logs)
|
||||
# -f FILTER Logcat filter spec (default: *:V) – can also pass as positional args
|
||||
# --no-restart Do NOT auto-restart the app when process dies/startup fails
|
||||
# --help Show this help and exit
|
||||
#
|
||||
# Exit codes:
|
||||
# 0 Success / user interrupt
|
||||
# 1 Usage / config error
|
||||
# 2 adb / device error
|
||||
# 3 (unused now, kept for compatibility if you want to reintroduce timeouts)
