本工具可用于探测Android设备中的应用控件，可代替UIAutomator等工具

使用限制：

• Root设备中可以探测任意应用的控件
• 非Root设备中只能探测debug应用的控件

1. cd $project_root
2. virtualenv .env --python=python2.7
3. Windows:
   .env\Scripts\activate.bat
   Others:
   source .env/bin/activate
4. pip install -r requirements.txt

如果是Windows系统，还需要执行：

pip install -r requirements_win32.txt

python ui/app.py

python build.py versions(2.5.1.0)

• 如果macos上执行python脚本遇到以下报错：

This program needs access to the screen. Please run with a Framework build of python, and only when you are logged in on the main display of your Mac.

可以将以下内容写入文件：.env/bin/python

#!/bin/bash

# what real Python executable to use
PYVER=2.7
PYTHON=/System/Library/Frameworks/Python.framework/Versions/$PYVER/bin/python$PYVER

# find the root of the virtualenv, it should be the parent of the dir this script is in
ENV=`$PYTHON -c "import os; print os.path.abspath(os.path.join(os.path.dirname(\"$0\"), '..'))"`

# now run Python with the virtualenv set as Python's HOME
export PYTHONHOME=$ENV 
exec $PYTHON "$@"

并添加可以执行权限：chmod 775 .env/bin/python
