Sorry. I made a mistake. I've fixed it. Pull again. You can test it: 1.pull code to c:/android_env_for_windows 2.cd c:/android_env_for_windows 3.pip install -e . 4.python examples\run_random_agent_win32.py

[YangBa78]

Thanks for your work. I tried it again. It went well in step 1-3. But still got errors in step 4:

I can successfully initialize the emulator, but the code stops running once the phone is done initialization.

[yizhangliu]

Why 'win64'? Keep this: 259 if sys.platform != 'win32':

[YangBa78]

My laptop is win64, but I didn't change the code. Does it work on win64?

[yizhangliu]

259 if sys.platform != 'win64': --> 260 os.mkfifo(self._fifo)

-- According to your information, your system is not 'win64'. You should check it in python console: print(sys.platform)

[YangBa78]

The output is win32. Strange....

What should I do next?

[yizhangliu]

Not strange. Your python is 32 bit.
Next， you should modified 'win64' to 'win32'. Good luck.

[yizhangliu]

To avoid puzzle, I've modified some code. Like this: platform.system() != 'Windows' Replace for:
sys.platform != 'win32':

[YangBa78]

It works. Thanks for your help. I really appreciate it! The code works well for the windows. You could close this issue.
