Sending data from app to live database working on desktop but not in mobile.

[mahmud al hasan]

I have created a signup app using kivy where I am sending data to live mysql database. The app works on desktop but not working after I created apk and crash every time. I have failed to connect database from android app. 

Now I want to know -

1. Is there any problem with my app?
2. What should be the requirements for buildozer.spec file for my app?
3. Should I need to add anything to connect the app with live database?

I have attached my project file where I used rest api to connect with my server. Feel free to look at those and upload buildozer.spec file for the app if necessary.



signup.py

from kivy.uix.boxlayout import BoxLayout

import requests, json, urllib3

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

class SignupPage(BoxLayout):

    def signup(self):

        username, password = self.ids.username.text, self.ids.password.text

        info = {

            "signup": [

                {

                    "username": username,

                    "password": password

                }

            ]

        }

        # headers = {"Content-type": "application/json"}

        url = 'https://talhatraining.org/signup/signup.php'

        resp = requests.post(url, data=dict(info=json.dumps(info)), verify=False)

        if resp:

            if  username and password:

                print('Data successfully saved!')

            else:

                print('Please enter user name and password!')

Have you added internet permissions for android in your requirements? You will also need openssl as it's a HTTPS request....

Yes, I have added internet permission for android in requirements and I have attached the buildozer.spec file here. 
I have added request, urllib3 but didn't use openssl.

The problem solved! I have included some requirements in the spec file which solved the issue.

requirements = kivy,requests,openssl,urllib3,futures,kivymd
