Installing Buildozer in Windows.

fcntl module is not supported in Windows, which throws an ImportError.
So the importing and usage of the module is now done if it exists. Else ignores the procedure.
Major changes at line no 38 and 267
Also changed all statements to print() rather than print.. which will now support both python 2 and 3
Also we might need to add http.server module for python 3.
