App is crashing on Android

[Dawid Kapciak]

Hi, I hope someone will help me here. I've made program, pretty complex as for me but acually it's a simple dating app. I'm using pyrebase as authorize provider and postgresSQL as a db provider. I'm pretty stuck right now, don't know what to do, so any help would be awesome!
Here is the error im getting on ubuntu:

#   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.

As I remember you can't use the postgresql library directly kivy android build, that was the reason to build an API for my project one year ago.

Usually you can find a recipe for any package you need, but for me with postgresql it didn't work I don't know now if it got fixed or not, as I said that was one year ago.

To be honest i don't know how it should look, i've got 4 tables in postgres, one with user data like name, surname, date of birth, gender etc. second with hobbies where i've put an id and lot of hobbies like running, programming, photography etc.

Third user_interests where i store user_id and interests_id like 6 1, 6 2, 6 3, 6 4 ... which means user 6 likes programming, running, filming, photography. And the last one 'connections', where i store connections between people so user_1 and user_2 are disliked, or matched or waiting for user_1 to like or dislike user_2. I just don't see it in NoSQL.

[Dawid Kapciak]

This is the example of one select that im currently using:

if match_id is None:
query = """
SELECT local_id
FROM user_info
WHERE gender = %s
AND interested = %s
AND local_id NOT IN (
SELECT user_id_2
FROM connections
WHERE user_id_1 = %s
AND status = 'user_2'
OR status = 'matched'
OR status = 'disliked'
)
AND local_id NOT IN (
SELECT user_id_1
FROM connections
WHERE user_id_2 = %s
AND status = 'user_1'
OR status = 'matched'
OR status = 'disliked'
)
ORDER BY CASE WHEN seen > 0 THEN likes::float / seen ELSE 0 END DESC
LIMIT 1
"""
self.cursor.execute(query, (target_gender, target_interest, local_id, local_id))
match_id = self.cursor.fetchone()

I don't get it, why do I need an API? Couldn't I just shove it all in into firebase database or even Mongodb?

[David Klargstein]

Yes you can, but since your database is so simple it's better to use something simple. Also using something like postgresql or others might get a bit hairy for you, this is why I advised you to either use SQLite or an API.

I need that program for engineering thesis so theoretically speaking it could work only on one device with SQLite. API seems like overkill for my case, also I don't have that much time. I think im gonna try SQLite right now. Thanks for help!

It's because you removed the pycparser package which you are using auth.py, are you sure pycparser is compatible without needing a build recipe?

These are my current requirements:
requirements = python3==3.9.0, kivy==2.2.1, kivymd, pillow, pyrebase4, python-dotenv, oauth2client, gspread, httplib2,protobuf,pyopenssl,google-auth-oauthlib,pyasn1,pyasn1-modules,rsa,requests,google-auth-httplib2,openssl,google-api-python-client,google-auth,credentials,oauth2,google,cachetools,urllib3,chardet,idna,requests_oauthlib,oauthlib,pyparsing,gcloud,googleapis-common-protos,pycryptodome,python-jwt,jws,certifi,charset-normalizer==2.1.1,requests-toolbelt,jwcrypto,cryptography,deprecated,wrapt,pycparser==2.21
As far as i know, the recipes are being used whenever I mention them in the requirements right?
Also some guy on the discord told me something like that:
Poncho 🇲🇽: "you require the -dev version of multiple libraries so the compiler can build a distribution for android on the arch specified. ideally build essentials should get you the base libraries needed, otherwise, check the recipes and see if you can build them on your system (by clonning the git repo and installing /building the package) this will enable you to see what is missing on your system and be able to compile whatever deps you can't.
keep in mind it's quite time consuming, but a different approach is trying to use an AI with RAG, so you could request information from it. for now the only one i know it has RAG and other plugins it's MS copilot on bing, i think bard also has RAG to be able to search in the web and formulate a coherent response, but i'm not sure tbh.
other than that, check, package by package, and see what compiles and when it stops working"
So it might be something with recipes, but i dont have an idea how to even check it
