buildozer Install python 3.8.1

[TSoer]

Versions

• Python: 3.7.5
• OS: Xubuntu
• Buildozer: 1.0.1

Description

When you start buildozer. Installs python 3.8.1 I have a suspicion that because of this I get a ReferenceError error. How do I set preferences so that apk builds on python <3.8?

[tshirtman]

you should be able to set the python version in buildozer.spec by putting for example python==3.7.5 in the requirements line.

[TSoer]

Yes, I did as you said

requirements = python==3.7.6,kivy,kivymd==0.104.0,sqlite3

But while buildozer is running, you can see the logs

[INFO]: Downloading hostpython3

after buildozer downloads work on errors

ERROR: Could not find a version that satisfies the requirement python==3.7.6 (from -r requirements.txt (line 3)) (from versions: none)

Thank you in advance

Oops yes, it should be python3==3.7.5 (note the 3). We should probably re-alias this as we only support python3 recipe anyway.

[AndreMiras]

Could you please share the actual log still. Please share the complete log including the buildozer.spec file

After building apk. I started getting other errors. and the application on the phone does not start, so I can’t say with confidence that I’ve packed python 3.7.6, but pay attention to the buildozerLog file, it can be seen that python 3.8.1 will be downloaded

[AndreMiras]

Oh OK thanks, I wanted to see the logs because earlier you said (deleted?) the error was the same with python3==3.7.5 and I had my doubt that's why I needed the full log 😅
If the issue you have now is a runtime one, then this task can be closed since it's solved right?
For the runtime issue you also need to check the logs. But it could really be "just" this:
kivy/python-for-android#2169
#1091
kivy/python-for-android#2167

Your settings. Collect apk files that do not work.

In order to select the python version. The argument python3 == 3.7.5 is not enough. In the buildozer.spec file, the requirements section must additionally specify hostpython3 == 3.7.5. An example is presented below

requirements = hostpython3==3.7.5,python3==3.7.5,kivy,kivymd,sqlite3
