I can't build apk

[johnied]

Question

Hello community,

This is the first time I am trying to make an .apk with flet build. I have installed ANDROID Studio and fixed all flutter issues (Flutter Doctor says No Issues Found!). I have added the following paths to Environment Variables:
C:\Users[user]\AppData\Local\Android\Sdk\cmdline-tools\latest\bin
C:\Users[user]\AppData\Local\Android\Sdk\platform-tools
C:\Users[user]\AppData\Local\Android\Sdk\build-tools\35.0.0

The only packages I am importing to my app is flet and requests. So the requirement.txt contains the following:
flet>=0.22.0
requests==2.32.3

I am using flet build apk -vv and the process freezes at the following point:

Can sombody help me understand as to why it freezes after installing collected packages?
What is the next step of the build process?
It seems that it cannot complete the next step, but no error is generated, it just goes forever.

Thank you in advance for your time.

这个命令打包成功率，比较低。有个本地打包安卓应用的国家就好了，可以改变这一现象

[LegendaryPistachio]

The success rate of this command for packaging is quite low. It would be great to have a local solution for packaging Android apps, as that could change this situation.

Indeed, but in my case I think there is something wrong with my setup. It uses ony flet and requests.
It should be compiling normally.

Is there a step by step guide to follow, so that I perform all the steps correctly?

Thank you very much.

The problem was with flet 0.24.1. After installing flet 0.25.0.dev3570, the app compiled succesfully.
