My APK files which I build with Buildozer do not work

[Hiroaki Kaneko]

Hello,

I built APK file from a simple py code with Buildozer to test it.

I was able to install  it in my android device safely.

When it boot, the player is displayed , but a mp4 file does not start.

The original main.py file and MP4 file work well using KIVY LAUNCHER installed in my same device.

Why?

May be , I think that the path of the MP4 file is wrong.

Please investigate my py code for building APK file.

My android device is ODOROID-XU3 lite.

AndroidOS version is "4.4.2" .

My development enviroment is Ubuntu14.04LTS 64bit.

 

My py code is the following.

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

import kivy

kivy.require('1.2.0')

from sys import argv

from os.path import dirname, join

from kivy.app import App

from kivy.uix.videoplayer import VideoPlayer

class VideoPlayerApp(App):

    def build(self):

        if len(argv) > 1:

            filename = argv[1]

        else:

            curdir = dirname(__file__)

            filename = join(curdir, '.../storage/sdcard0/myappfiles/test_1080p.mp4')

        return VideoPlayer(source=filename, state='play')

if __name__ == '__main__':

    VideoPlayerApp().run()

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

The filename you are creating seems a bit strange.

You are joining the current directory with a path that looks like
should be absolute ('/storage/sdcard0...')

Also, I have never seen the use of '...' (3 dots) in paths. One dot
means the current directory, 2 dots mean the parent directory.

Thank you for your post.

The APK file was installed in /date/app-lib/org.test.myapp .

At first, I tried the absolute pass /storage/sdcard0/myappfiles/test_1080p.mp4.

However,not work.

Next, I tried the relational pass .../storage/sdcard0/myappfiles/test_1080p.mp4.

Again, not wrok.

What is a mistake?

I tried the code below

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

import kivy

kivy.require('1.2.0')

from sys import argv

from kivy.app import App

from kivy.uix.videoplayer import VideoPlayer

class VideoPlayerApp(App):

    def build(self):

        if len(argv) > 1:

            filename = argv[1]

        else:

            filename = '/storage/sdcard0/myappfiles/test_1080p.mp4'

        return VideoPlayer(source=filename, state='play')

if __name__ == '__main__':

    VideoPlayerApp().run()

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

However, do not work.

Please tell me a solution.

[niavlys]

filename = 'test_1080p.mp4'
should just work?


filename = join(dirname(__file__),'test_1080p.mp4')

should work too;

3rd option, import kivy.ressources, which is basically a wrapper around the latter solution.

[Hiroaki Kaneko]

Thank you for your advice!

I tried the following.

-----

class VideoPlayerApp(App):

    def build(self):

        if len(argv) > 1:

            filename = argv[1]

        else:

            curdir = dirname(__file__)

            filename = join(curdir, 'test.mp4')

        return VideoPlayer(source=filename, state='play')

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

However can not work......

I place "main.py" and "test.mp4" in same directory "Kivy_test1".

Then, I built APK file with Buildozer.

I think that I must not build test.mp4 together, must put test.mp4(it is a file to play back) in the directory"sdcard0" in case of Android.

In this case, how should I write the path of "test.mp4" by Python.

just thinking of another possible issue: by default, buildozer.spec states:

# (list) Source files to include (let empty to include all the files)
source.include_exts = py,png,jpg,kv,atlas

have you add mp4 extension to this list?

in case you haven't, your video file won't be bundled into the apk...

[hiro.kaneko]

I apologize for the delay in replying.

Yes,　this line was comment out.

My spec file the following.

#    -----------------------------------------------------------------------------

#    List as sections

#

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

#    Each line will be considered as a option to the list.

#    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

requirements = kivy

you have to add ffmpeg as requirement.

[hiro.kaneko]

It is fine!!

The APK file worked well !

I could resolve the trouble.
Thank you!

Thank for the support of you and all forum members.
