在Pydroid 3中使用Selenium时，模块及子模块可正常加载，但浏览器无法启动，报错信息如下：

Traceback (most recent call last):
  File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.11/site-packages/selenium/webdriver/common/driver_finder.py", line 67, in _binary_paths

    raise WebDriverException(f"Unsupported platform/architecture combination: {sys.platform}/{arch}")
selenium.common.exceptions.WebDriverException: Message: Unsupported platform/architecture combination: linux/aarch64

引发后续异常：

1. 手动适配aarch64架构的ChromeDriver #

Selenium Manager暂不支持Android的aarch64架构，需手动下载对应版本的ChromeDriver：

• 下载与手机Chrome版本匹配的aarch64架构ChromeDriver
• 将文件放到Pydroid有权限访问的路径（比如内部存储的Download文件夹）
• 初始化WebDriver时手动指定驱动路径：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# 配置Chrome适配移动端环境
chrome_options = Options()
chrome_options.add_argument('--headless')  # 移动端推荐无界面模式
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')

# 替换为你的chromedriver实际路径
driver = webdriver.Chrome(executable_path='/storage/emulated/0/Download/chromedriver', options=chrome_options)

2. 改用Firefox GeckoDriver替代 #

Firefox的GeckoDriver对aarch64架构支持更友好：

• 下载适配Android aarch64的GeckoDriver，确保与手机Firefox版本匹配
• 手动指定驱动路径初始化：

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

firefox_options = Options()
firefox_options.add_argument('--headless')

# 替换为你的geckodriver实际路径
driver = webdriver.Firefox(executable_path='/storage/emulated/0/Download/geckodriver', options=firefox_options)

3. 降级Selenium版本 #

部分旧版本Selenium的驱动查找逻辑兼容性更强，可尝试降级到4.8.x版本：
在Pydroid终端执行：

pip install selenium==4.8.3

降级后手动指定驱动路径即可绕过Selenium Manager的架构校验。
