The application I am writing compiles correctly, but when I push it to a tablet and run it, it crashes as soon as it gets past the 'Loading' screen.

Here are my system specs:

OS: ubuntu 16.04 64-bit
Memory: 15.6 GiB
Processor: Intel® Core™ i7-4790 CPU @ 3.60GHz × 8

The device I am trying to deploy to is an ASUS ZenPad 3s 10. I have turned on the developer options, but it is not rooted as it seems it is not possible at the moment. The tablet is running Android 7.0.

Here is my buildozer spec file:

#    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

You can debug the application using logcat. With buildozer, you can get this with buildozer android logcat.

If you can't resolve the problem with that information, please post the full details including this log on the kivy-users mailing list.

AlexPicaro commented 7 years ago

I have the log from logcat (linked in the original post, as it is ~14000 lines long), but I can't make sense of it. The line that seems to cause the crash is unable to stat file for the executable "/system/bin/sh": Permission denied

I'll post in the kivy-users mailing list.

inclement commented 7 years ago

Oh, sorry, I missed that. The important part is as below. It looks like dlib has compiled components and will need a recipe to work with p4a. Although the error is about 64 vs 32 bit, it's likely that it's only 64 bit because it's built for the wrong (desktop) architecture.

Thanks for the reply!

I tried following the p4a documentation and buildozer documentation about recipes. I forked and cloned the p4a Github repo and modified the spec file as follows:

# (str) python-for-android git clone directory (if empty, it will be automatically cloned from github)
p4a.source_dir = ~/Desktop/python-for-android

I then created the following directory: Desktop/python-for-android/pythonforandroid/recipes/dlib Under that directory, I created the following recipe, named __init__.py:

from pythonforandroid.toolchain import Recipe

class DlibRecipe(Recipe):
    name = 'dlib'
    version = '1.0'
    url = 'http://dlib.net/files/dlib-19.4.tar.bz2'

    def prebuild_arch(self, arch):
        super(DlibRecipe, self).prebuild_arch(arch)
        # Do any pre-initialisation

    def build_arch(self, arch):
        super(DlibRecipe, self).build_arch(arch)
        # Do the main recipe build

    def postbuild_arch(self, arch):
        super(DlibRecipe, self).build_arch(arch)
        # Do any clearing up

recipe = DlibRecipe()

I'm not sure what else I'm supposed to include in the recipe, as I am struggling to understand the documentation. I have looked at other recipes in the repo and some of them are that simple. When I build my project, I get the following lines which seem to say my recipe is being used:

[INFO]:    Of the existing distributions, the following meet the given requirements:
[INFO]:     etsdemo: includes recipes (hostpython2, sdl2_image, sdl2_mixer, sdl2_ttf, python2, numpy, sdl2, six, opencv, pyjnius, kivy, scikit-learn, scikit-image, imutils, scipy, dlib), built for archs (armeabi-v7a)

However, when I deploy the application to the tablet, I get the same error message:

Hello,

Have you tried to build without all the libraries you put in your spec file, and add them one by one ? I think opencv and imutils make the app crash when launching on the phone. Also shouldn't it be opencv-python as we do pip install opencv-python ?

lackfadiriso commented 4 months ago

I am new to Python Kivy and I compiled the apk without any errors, but when I run it, it crashes after the loading screen. buildozer.spec:# This .spec config file tells Buildozer an app's requirements for being built.

-----------------------------------------------------------------------------

Notes about using this file:

#

Buildozer uses a variant of Python's ConfigSpec to read this file.

For the basic syntax, including interpolations, see

https://docs.python.org/3/library/configparser.html#supported-ini-file-structure

#

Warning: Comments cannot be used "inline" - i.e.

[app]

title = My Application # This is not a comment, it is part of the title.

#

Warning: Indented text is treated as a multiline string - i.e.

[app]

title = My Application

package.name = myapp # This is all part of the title.

#

Buildozer's .spec files have some additional features:

#

Buildozer supports lists - i.e.

[app]

source.include_exts = py,png,jpg

^ This is a list.

#

[app:source.include_exts]

py

png

jpg

^ This is an alternative syntax for a list.

#

Buildozer's option names are case-sensitive, unlike most .ini files.

#

Buildozer supports overriding options through environment variables.

Name an environment variable as SECTION_OPTION to override a value in a .spec

file.

#

Buildozer support overriding options through profiles.

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

#

Environment variable overrides have priority over profile overrides.

I can't run it with logcat because I'm in a virtual machine, I send it directly to the phone via WhatsApp and try it.
