adb獲取啓動activity(adb get launcher activity)

網上可用的很少，在此紀錄下：

import subprocess


def sh(command, print_msg=True):
    p = subprocess.Popen(
        command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    result = p.stdout.read().decode('utf-8')
    if print_msg:
        print(result)
    return result


def get_launcher_activity(package_name):
    result = sh("adb shell dumpsys package %s" %
                (package_name), print_msg=False)
    if not result:
        return
    end_index = result.index("android.intent.category.LAUNCHER")
    if end_index >= 0:
        start_index = (end_index - 150) if end_index - 150 >= 0 else 0
        lines = result[start_index:end_index].split(' ')
        for line in lines:
            if package_name in line:
                return line
    return ''


print(get_launcher_activity('com.66.66'))
