As said by Stefan Krah in http://bugs.python.org/issue23496#msg236886, Android ports can use pure python decimal module. Of course I can, but _decimal is always built and error messages are spamming. This change allow disabling _decimal from ./configure.

For the complete build process, have a look into scripts and patches from https://github.com/yan12125/python3-android.

I thought you solved the locale problem in #20305. So it still does not build?

In any case:  It is not uncommon that some C module does not build.

You can disable modules in setup.py:

  # This global variable is used to hold the list of modules to be disabled.
  disabled_module_list = []

Regarding #20305: Now building is fine, while some runtime errors exist. I don't see reasons running ncurses on Android, so kicking those errors are not in my plan.

For this change: Thanks for pointing that variable - not noticing it before. Seems I still need to patch setup.py for disabling some specific modules? I don't like patches. They're just temporary workarounds for me. I see issue20210 proposing a general solution for disabling modules. Maybe I'll working on that instead.

After #26846 _decimal builds on Android.
