Kivy app crash immediately (SIGABRT)

[ADR-007]

Versions

• Python: 3.7.1
• OS: Ubuntu 18.04.2
• Kivy: 1.11
• Cython: 0.29.9
• Android: 9 Pie (EMUI 9.1, Huawei P30 Pro)
• Buildozer: 0.40.dev0

Description

1. buildozer android debug deploy run
2. app starts on the phone, show Could not extract private data and die

I fixed tarfile.py: I changed itn(info.get("uid", 0), 8, format), to itn(info.get("uid", 0), 12, format),. It was the only way to make it work.

I spent a lot of time to figure out how to fix it, found a lot similar problem, but there was not any solution.

buildozer android debug deploy run

#
#    You can define all the "list" as [section:key].

#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

Hi,

I have similar problem as you had. Every app I build via buildozer crashed in android, but works like charm om my Xubuntu.

Could you please point me, how did you solve the issue?

Thx

Hi, just find tarfile.py and change _create_header function as in my previous comment

This doesn't work for me. I even deleted tarfile.cpython-37.pyc in /usr/lib/python3.7/_pycache_
folder.
I have similar problem with crushing on start.

I have been trying to import openpyxl in my main.py file.When i run buildozer android debug everything seems to be working fine.But when i open the app on my android it crashes.Can you help me with finding the solution.

Why can't i import openpyxl.
When i don't use this module in my main file everthing works good but after importing it the app crashes.

[tshirtman]

please check that you have the same error in your logcat as the one shared in original post before commenting or adding a "me too" there are lots of unrelated possible reason for your app to crash, don't mix these issues in the same post.

@ADR-007, I am just having this "couldn't extract private data" error, and tried to locate the tarfile.py you mentioned. It seems there are quite a few of them in my Ubuntu system. I tried to modify some relevant ones according to your suggestion, but it doesn't seem to help. Perhaps I did not get the right file. Can you specify which file you modified?

where tarfile.py is located

[ADR-007]

I found a workaround:
tarfile.py:

    @staticmethod
    def _create_header(info, format, encoding, errors):
        """Return a header block. info is a dictionary with file
           information, format must be one of the *_FORMAT constants.
        """
        parts = [
            stn(info.get("name", ""), 100, encoding, errors),
            itn(info.get("mode", 0) & 0o7777, 8, format),
            itn(info.get("uid", 0) % 256, 8, format), # <-------------------------
            itn(info.get("gid", 0) % 256, 8, format), # <-------------------------
            itn(info.get("size", 0), 12, format),
            itn(info.get("mtime", 0), 12, format),
            b"        ", # checksum field
            info.get("type", REGTYPE),
            stn(info.get("linkname", ""), 100, encoding, errors),
            info.get("magic", POSIX_MAGIC),
            stn(info.get("uname", ""), 32, encoding, errors),
            stn(info.get("gname", ""), 32, encoding, errors),
            itn(info.get("devmajor", 0), 8, format),
            itn(info.get("devminor", 0), 8, format),
            stn(info.get("prefix", ""), 155, encoding, errors)
        ]

        buf = struct.pack("%ds" % BLOCKSIZE, b"".join(parts))
        chksum = calc_chksums(buf[-BLOCKSIZE:])[0]
        buf = buf[:-364] + bytes("%06o\0" % chksum, "ascii") + buf[-357:]

Hm... I found it during debugging... try to run python3 -c 'import tarfile; print(tarfile.__file__)' and patch this file

(sorry I missed the question)

[WhyAsh5114]

I tried to change the tarfile and it still crashes, my issue is a bit different as the app crashes in a particular screen, (not on PC, only Android), the error message seems very similar which is why I am also commenting here (there aren't any errors in my code, it works perfectly on PC).

[BorisCSanto]

Hi, i had a bug like this, with SIGABRT and the end line about "/lib/arm/libpython3.8m.so (Py_Exit+28)"

My app was running good on my PC , but not in my android (crashing on loading).
I don't know why your app crashes but I solved my problem with adb:
After connection on my phone with a usb cable, and establishing a connection with my phone I do this:
adb logcat | grep python
When i launched my app, it allowed me to get lines of my main.py file which was erroring.

Good Luck

[dera001]

SIGABRT occurs if theirs is a CPU intensive operation happening while the app is still launching or thread operation going on
check the imported modules for methods that might cause a low memory faults, on_start of the app.
