Hello, I tried your code and my phone is using ARMv8-A architecture. I also included the CAMERA android permission and the libraries in the buildozer.spec file, however the app is crashing. The logcat is producing errors related to kivy clock and it also stated that there is no attribute blit_buffer at line 44.

I'm watching your tutorial now in May 2022 and Android Studio's 'tools' directory is not available. Do you know how to solve this? Please any help I'll be very grateful

[@soonislive]

bro where threading library😮by using threading you reduce lag. it will seperate ui and camera process so that you will not feel lag in ui

[@sksahil4374]

no use .I was testing with this code .

[@takashifukushima5013]

Hello! Thank you so much for this great content! I get a noclassfound error for camera info when I run on python. Also, I created apk regardless to the error, but the app crashes when I open it. I manually turned on camera / storage permission, but it still crashes. Could you please help me?

[@sksahil4374]

see all adb logs and put logs in Kivy user support group

This does not access the front camera on a tablet. Any ideas?

[@sksahil4374]

read java android code for front camera .and connect with Python using pyjnius

[@demigodsadventures]

How can i do that on windows ?
Please suggest anything!

[@sksahil4374]

Use virtual machine

[@demigodsadventures]

Thanks for the reply.
It's been one month, and I have tried with buildozer in coolab. I also tried the gitHub Action method, but nothing worked with opencv.
Will this method work as of now ?? Because in coolab, I had to check with some new libraries when I used buildozer, like libff7 instead of libff6.

[@jovyalchoussi4268]

There is always an error when i change resolution ((640, 480) or (480, 640 )) to more (like 1024, 724 ).
Please Sir how to solve it ?

you have to maintain screen aspect ratio i think.

@@jovyalchoussi4268 here we are accessing android camera via Java Android api ..and pyjnius is bridge between python and Java .so we can use java classes in python through pyjnius ..so to configure android camera you have to read camera API of Java Android .then connect java code to python via pyjnius.

Bro is there any way to import android in Pycharm. Because when we use Java class to confirm it we need everytime to do apk. Is there any solution for it?

[@sksahil4374]

You need Android OS to run java android code.

[@sksahil4374]

Java android developers are also doing that ..They every time build and test on Android OS ...I will suggest you use Physical Android device ..
