Custom Recipe

[Pkore]

I need to incorporate the 'python-rtmidi' library in my android project and have been trying to write a recipe for it. I haven't had success with doing that so I was wondering if someone could give me some pointers. Keep in mind I'm a total recipe n00b so I basically need a step by step guide. I've seen the docs on the python-for-android website and I'm still lost. Anyone up to the challenge of helping out a n00b? 

Thanks in advance! 

[Pkore]

I forgot, here are the contents of my recipe.sh file:

class RtMidiRecipe(Recipe):

    url = 'https://github.com/SpotlightKid/python-rtmidi/archive/master.zip'

    version = '1.0.0'

    md5sum = '4f3dc9a9d857734a488bcbefd9cd64ed'

    depends = ['cython']  # These are just examples

recipe = RtMidiRecipe()

Be gentile:) 

[Alexander Taylor]

This is a python recipe for the new toolchain, so call it __init__.py rather than recipe.sh.

If it uses cython, Use CythonRecipe as the base class, rather than Recipe.

Other than that, what is the build problem?

Will python-rtmidi work on android or is it only desktop linux?

[Pkore]

Can anyone help with this? I would really like to be able to write my own recipes. I'll share each one when I get them working.

[Pkore]

Bump.

[Aaron Bell]

I would answer, but I don't know! :|

[Pkore]

Lol! Well, thanks for the reply none the less;)

[Alexander Taylor]

This log indicates that python-for-android is not using your recipe, and
is instead trying to install the module with pip (which doesn't work
because it has compiled components). What steps did you follow to try to
make the recipe be used?

Well, I created a folder named python-rtmidi in the '.buildozer/android/platform/python-for-android/recipes' folder in my app's directory. I then saved the above recipe code in that folder as '__init__.py' and listed 'python-rtmidi' as a requirement in my .spec file and started the build process. Am I doing that part wrong? Should the recipe go under a different directory on my machine? Like I said, I'm a n00b. 

  Just to reiterate, this is on the buildozer VM.

[Pkore]

Also, what's the md5 about? Do I need it? I just left it cause it was part of the example;)

[Pkore]

Don't mean to be a pest, but I'm still not getting anywhere with this.

[Alexander Taylor]

There is some documentation about creating recipes at
http://python-for-android.readthedocs.io/en/latest/recipes/ , and you
can use your recipe without modifying the python-for-android build
folder as described at
http://python-for-android.readthedocs.io/en/latest/quickstart/#recipe-management

Beyond that, please post the recipe contents and details about what
problem you currently get when trying to build it.

It might be easier to post this information as a pull request on github,
if you like.
