ValueError: read of closed file

[Mark Leong]

I have previously successfully built the apk using MX Linux 19.x (python 3.8) and using the apk.

However due to some hardware issue (using a dated computer), I have switch the os to Debian 10 (xfce) - it is must faster and more pleasant to use.  I am now setting up my programming environment again.

The system uses python 3.7.3 and I manage to set up kivy.  The programme runs without issue on the computer and packaged using PyInstaller too. 

However when I tried to build the apk, the got the following error (last few lines):

    urlretrieve(url, filename, report_hook)

  File "/usr/lib/python3.7/urllib/request.py", line 1824, in retrieve

    block = fp.read(bs)

  File "/usr/lib/python3.7/tempfile.py", line 620, in func_wrapper

    return func(*args, **kwargs)

ValueError: read of closed file

I have included the following in the buildozer.spec:-

android.minapi = 24

android.sdk = 24

android.ndk = 19b

android.ndk_api = 24

I am using kivy version 2.0.0

Appreciate help in resolving the issue.

Looks like it is not finding the NDK.

Did you type 'y' to the Google license agreements?

To redo that step, delete ~/.buildozer

Can you please paste in the whole traceback instead of the last few lines?
