Kivy app working on PC but not on Android with Buildozer (ACCESS_SURFACE_FLINGER denied)

[Ghiom]

Hi there and first of all a big thanks to all of you who helped me without knowing it. For a noob like me, those fora are really precious.

I'm new to coding, learned Python3 to see if I can, and trying to do an Android Application for my girlfriend's professionnal activity.

I scrap informations on her website (with Scrapy), put those on a JSON file, modify those a little and use Kivy and Float Layout to add them on screen. The most advanced part (for me), is a function to make a phonecall on android.

All works really good on my PC (Ubuntu or Windows), but when it come to Android, it crash at launch (after "Loading" I get a blackscreen).

First, Buildozer asked for a lot of requirements (you will see that on the .spec file), after that problem was solved, I ran on an other one with an android permission denied ACCESS_SURFACE_FLINGER. I asked with the builddozer.spec and that's not good as you can see on logs.

I also used some code to ask in my main.py

from android.permissions import request_permissions, Permission
request_permissions([Permission.ACCESS_SURFACE_FLINGER])

and it returns that Permission as no ACCESS_SURFACE_FLINGER argument.

Can you give me a hand please ? I spent 2 days searching how to make it works and my skills (and google) are not enough.

#    -----------------------------------------------------------------------------
#    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 debugt

What seems to be the problematic part of my logs when doing

buildozer -v android debug deploy run logcat > my_log.txt

[Robert Flatt]

I ran on an other one with an android permission denied ACCESS_SURFACE_FLINGER. I asked with the builddozer.spec and that's not good as you can see on logs.

I also used some code to ask in my main.py

from android.permissions import request_permissions, Permission
request_permissions([Permission.ACCESS_SURFACE_FLINGER])

and it returns that Permission as no ACCESS_SURFACE_FLINGER argument.

As shown here:  https://github.com/kivy/python-for-android/blob/develop/pythonforandroid/recipes/android/src/android/permissions.py

I suspect ACCESS_SURFACE_FLINGER is not the issue. Why are you asking for it in the .spec ?

The first issue is probably what is shown in the Traceback, but the log shown is truncated.

If you don't understand the Traceback, post the FULL Traceback here, all of the Traceback is important but the last line is the most important.

There is some unusual stuff here, I wonder how this story will unfold?

[Ghiom]

Thx for your response !

I asked for the permission cause my logs shown me that permission was needed.

I'll show you the logs, but they are huge, that's why I troncated them (that was apparently a bad idea).

Really thanks for your help, I'm clearly out of my league :D

[Robert Flatt]

The size of the log is not an issue, attaching as .txt is definately the right way to share.

Some unusual stuff here, so by suggestions will contain "probably" - validate with small test cases.

At the end of the Traceback we see:

WARNING: stderr: 2020-10-27 08:45:24 [kivy] WARNING: stderr: 2020-10-27 08:45:24 [kivy] WARNING: stderr: 2020-10-27

Several things,

1) this message is coming from Java code; either it is the pyjnius code (I don't think so - but test this by removing it) or it is Android is being asked to do somthing it can't do.

2) the repeated WARNING:stderr is weird.

3) the error looks to be "failed to open /proc/15914". On Android creating a process (presumably with exec()) is probably going to fail because Android is not POSIX

Some possibilities (my guess the issue is A), but ....):

A) that exec() is in the webbrowser package, and uses an exec() to start a third party webbrowser - and depends on POSIX.

Test this by creating a HelloWorld app, add two things: import webrowser and in on_start() put webbrowser.open().  Does this crash in the same way?

B) process = CrawlerProcess(s
Try commenting this. Also move it to on_start()

It is possible webbrowser/scrapy is not going to work. Look at beautifulsoup4, does that do what you want? Avoid diapointment try a small test case first.

I asked for the permission cause my logs shown me that permission was needed.

We should look at this later. 

You need INTERNET, WRITE_EXTERNALSTORAGE, and whatever the phone needs.

The requirements can be trimmed too.

Hi Robert and thanks for all your help.

I've done multiple tests like you asked (on new apps and on my project), and the problem seems to be with Scrapy. If I comment all the scrapy stuff and put a handmade agenda_list[] the application launch. The webbrowser buttons are working.

So... without Scrapy my app is useless... I need to find something else. I'll look on Beautifullsoup I think.

Other than that, the "Call" button doesn't work so Jnius isn't doing his job or maybe I lack a permission for that on Android ? I asked for CALL_PHONE, but it didn't work and it seems that Jnius is having a problem with the PythonActivity Class.

I give you some logs attached.

Thanks again.

[Robert Flatt]

Try starting scrappy in a thread rather than a process, if it works on the desktop it will work on Android.

This should be "org.kivy.android. "  not "org.renpy.android. "   - obsolete documentaion

I'll be interested to know if webbrowser works.....

Hi and sorry for not showing signs of life those days, computer issues.

Scrapy was a problem, so I used beautifulsoup4 instead and now it works (I had a problem with htlmparser, but fixed with that workaround : https://stackoverflow.com/questions/23952484/buildozer-compiles-apk-but-it-crashes-on-android )

For jnius, I recently discovered plyer and it's way simpler to use. I can't manage to do a phone call with it (my application crash when I clic on it), but this way my application works on my phone.

I have graphic issues (text is not showing at the good size for titles and some squares on background are 1/5 the size shown on PC), the "Call" button don't work, but all the other stuffs are functionnal.

I put the main.py, buildozer.spec and modified htmlparser in attachment if you wan't to see.

Any help will be appreciated with my plyer issue.

Really thanks for your help Robert, was really kind of you to take time for a newbie like me :)

[Robert Flatt]

Give yourself a reward, you debugged some difficult stuff, and showed flexibility in finding solutions. Cool.
