how to fix?

[Guilherme Soares Lima]

# Copy application source from /mnt/c/Users/HP/Documents/testapp/C:\Users\HP\Documents\testapp\main.py

Are you still using windows?

 

BUILD FAILURE: No main.py(o) found in your app directory. This
file must exist to act as the entry point for you app. If your app is
started by a file with a different name, rename it to main.py or add a
main.py that loads it.
# Command failed: /usr/bin/python3 -m pythonforandroid.toolchain apk --bootstrap sdl2 --dist_name main.py --name Calcul4 --version 0.1 --package org.test.main.py --minsdk 21 --ndk-api 21 --private /mnt/c/Users/HP/Documents/testapp/.buildozer/android/app --android-entrypoint org.kivy.android.PythonActivity --android-apptheme @android:style/Theme.NoTitleBar --icon /mnt/c/Users/HP/Documents/testapp/C:\Users\HP\Documents\testapp\icon.png --orientation portrait --window --copy-libs --arch arm64-v8a --arch armeabi-v7a --color=always --storage-dir="/mnt/c/Users/HP/Documents/testapp/.buildozer/android/platform/build-arm64-v8a_armeabi-v7a" --ndk-api=21 --ignore-setup-py --debug

 It says: "didn ´t find main.py".

So that can be your entry file is not main.py or the source directory is not on buildozer.spec file. See this:

--------------- File: buildozer.spec -----------

...

source.dir = src

...

------------------------------------------------------------

Hope It helps.

[Guilherme Soares Lima]

If the entry file is not main.py, you can just rename it and be happy.
