Follow these steps to compile your kivy application to an APK on GitHub (No linux needed).

Note: This method is only recommended if you don't have access to a linux or mac system

1. Create an github account if you don't have.

2. Create a repository, you could also create it as private.

3. Goto your project directory (where main.py exists) and create a file in .github/workflows/build.yml (Create the folders if not already existed).

Many people state that kivy is slow. While this may be true it is mostly due to that python is slow to run on android devices.Thus it is in the programmer's hands to properly optimize their code so as to create a performant application.

Most of the lag on android devices runing kivy apps arise due to widget creation. Widget creation remains the slowest step in a kivy app. Here are some of the methods that I follow to optimize my apps and ensure I can hit 60fps even on old devices

    digits = digits_of(card_number)
    odd_digits = digits[-1::-2]
    even_digits = digits[-2::-2]
    checksum = 0
    checksum += sum(odd_digits)
    for d in even_digits:
        checksum += sum(digits_of(d*2))

Fix for Open GL on Intel HD Graphics 3000 - Windows 10

The drivers for Intel HD Graphics 3000 in Windows 10 does not expose all Open GL capabilities of the GPU. So software relying on Open GL features not present in Open GL 1.1 will not work. Using older versions of Windows or Linux might work since the chip have more features than the driver exposes.

The fix is to add a compatibility shim using the Windows ADK software.

1. Download and install Windows ADK
