[Yassin Marmoud]

I followed everything still not working how I can install that SDK manual much better cuz not fair to spend 3 days from an error to another error without getting any progress.
ps: I followed what shared here https://groups.google.com/g/kivy-users/c/-MNe0xpC50I

This exceed my knowledge try Discord https://discord.gg/X9SEe7Hb

BUT FIRST fix an existing issue the build directory must be on the Linux partition not the Windows partition.

See "Dont..." here https://github.com/kivy/buildozer/blob/master/docs/source/installation.rst#android-on-windows-10-or-11
