AKP build fails (android.py line 524)

First of all, thank you very much for the incredible amount work behind kivy !

python=3.6 / Ubuntu 18.04.1 LTS / kivy=1.10.1/ cython=0.25.2

I installed Kivy and Buildozer using this script of my own, following all instructions given here, here, and here.

I tried to compile the Pong example using this buildozer.spec file (please note the lines requirements = python3crystax==3.6,kivy and log_level = 2)

Here is the result of the command $ buildozer android debug logcat , the last lines being :

Cloning into 'python-for-android-new-toolchain'...
Traceback (most recent call last):
  File "/usr/local/bin/buildozer", line 11, in <module>
    load_entry_point('buildozer==0.35', 'console_scripts', 'buildozer')()

[...]

  File "/usr/local/lib/python2.7/dist-packages/buildozer/targets/android.py", line 524, in _install_p4a
    deps = re.findall("^install_reqs = (\[[^\]]*\])", setup, re.DOTALL | re.MULTILINE)[0]
IndexError: list index out of range

The problematic lines in android.py are:

[523]                setup = fd.read()
[524]                deps = re.findall("^install_reqs = (\[[^\]]*\])", setup, re.DOTALL | re.MULTILINE)[0]
[525]                deps = ast.literal_eval(deps)

These lines had already been fixed, see this issue and the fix #724.

In the setup file read by setup=fd.read() (namely /home/sui/Desktop/kivypong/.buildozer/android/platform/python-for-android-new-toolchain/setup.py), the interesting lines (=relative to the regex) are:

if os.name == 'nt':
    install_reqs = ['appdirs', 'colorama>=0.3.3', 'jinja2',
                        'six']
else:
    # don't use sh after 1.12.5, we have performance issues
    # https://github.com/amoffat/sh/issues/378
    install_reqs = ['appdirs', 'colorama>=0.3.3', 'sh>=1.10,<1.12.5', 'jinja2',
                        'six']

I'm not an expert but it seems to me that ^install_reqs = (\[[^\]]*\]) can't catch the string install_reqs = ['appdirs', 'colorama>=0.3.3', 'sh>=1.10,<1.12.5', 'jinja2', 'six'] .
I don't understand the logic behind this line of code so I can't go further.

By example, I don't understand the meaning of [0] in
[524] deps = re.findall("^install_reqs = (\[[^\]]*\])", setup, re.DOTALL | re.MULTILINE)[0]
since there are 2 lists of dependencies, the first one being only for NT system.

By the way, if I replace the regex used in re.findall() by install_reqs = (\[[^\]]*\]) (no more ^), I get two lists of dependencies (the first one for NT system, the second for the other systems), namely :
["['appdirs', 'colorama>=0.3.3', 'jinja2',\n 'six']", "['appdirs', 'colorama>=0.3.3', 'sh>=1.10,<1.12.5', 'jinja2',\n 'six']"] . I don't know how ast works so I can't tell if this result would is ok for ast or not. A new call $ buildozer android debug logcat with such a modification leads to the expected message:
Run "pip install -q --user 'appdirs' 'colorama>=0.3.3' 'jinja2' 'six'
... i.e. the dependencies expected for a NT system. Logically, the build fails some seconds later on my Ubuntu system with the message:
ERROR: The sh Python module could not be found, please install version 1.10 or higher

Finally, I bypassed those lines by installing manually the required depencies (namely, 'appdirs', 'colorama>=0.3.3', 'sh>=1.10,<1.12.5', 'jinja2', 'six') and by writing in android.py :

                setup = fd.read()
                deps = []
                #deps = re.findall("^install_reqs = (\[[^\]]*\])", setup, re.DOTALL | re.MULTILINE)[0]
                #deps = ast.literal_eval(deps)

... and the $ buildozer android debug logcat goes on and produces an AKP file. I don't know if the content of this file is ok - I have presently not enough time to launch it.

I hope this will help !
