Buildozer Fails to Install garden packages

[qodzero]

Versions

• Python: 3.7.6
• OS: Kubuntu 18.04
• Buildozer: 1.2.0

Description

No matter which app i run, even a simple example app. The moment I add a garden package as a requirement, buildozer crashes. with

Traceback (most recent call last):
  File "/home/albi/CUCINA/.buildozer/venv/bin/garden", line 189, in <module>
    GardenTool().main(sys.argv[1:])
  File "/home/albi/CUCINA/.buildozer/venv/bin/garden", line 71, in main
    options.func()
  File "/home/albi/CUCINA/.buildozer/venv/bin/garden", line 109, in cmd_install
    fd = self.download(opts.package)
  File "/home/albi/CUCINA/.buildozer/venv/bin/garden", line 170, in download
    data += buf
TypeError: can only concatenate str (not "bytes") to str

Going through the error log, I noticed that this is because, by default buildozer install Kivy-Garden==0.1.1 which for some reason simply doesn't work. I downgraded my Kivy-Garden to 0.1.1 and ran a simple garden install navigationdrawer. and the above error is the result so now I know for sure that the error is due to buildozer downloading the wrong version of Kivy-Garden because if I use Kivy-Garden==0.1.4, which is what Kivy requires, I can download my garden flowers. Ofcourse when I run buildozer android debug. Buildozer goes and downloads Kivy-Garden==0.1.1 again and this error comes back.

Solution

Please, could you make buildozer download the correct Kivy-Garden, i.e version 1.4.0 as 0.1.1 simply doesn't work?

buildozer.spec

Command:

buildozer android debug

Spec file:

The default spec file is fine, simply add any garden requirement

Garden is deprecated, now garden packages install like any other Python packages using the requirements list, refs #1142
Feel free to join Discord for support doing so if needed

Two questions then:

1. What if the target garden flower hasn't been migrated yet?Things start to get confusing real quick (of course i could just install it to my app with the --app flag, but what about newbies)
2. Why then does the garden.requirements spec option still exists when buildozer won't/can't use it? doesn't that confuse people even more?, naturally if someone sees that spec option they are likely to put their flower requirements there than on the actual pip requirements

[AndreMiras]

Yes it's all valid points, the very few unpaid core dev that we're do the best to spend time on the most important things. This comes with a cost of taking some shortcuts like this one.

1. yes theses flowers need to be migrated then
2. the option no longer exists in (unreleased) master https://github.com/kivy/buildozer/pull/1142/files#diff-0b68bfd12f75175020450064eae77a55L47
