如何从包中创建Kivy APK? [英] How do you create a kivy apk from a package?

问题描述

我有一个简单的python/kivy软件包，我希望从其中使用Buildozer创建一个Android APK.根目录下的软件包的组织方式为:

I have a simple python/kivy package from which I wish to create an android APK using Buildozer. The package from the root is organised as:

.
├── bin
│   ├── kivy_test-0.1-debug.apk
│   └── myapp-0.1-debug.apk
├── buildozer.spec
├── __init__.py
└── kivy_app
    ├── __init__.py
    ├── __main__.py
    └── source
        ├── main.py
        └── version.py

main.py模块是:

The module main.py is:

from kivy.app import App
from kivy.uix.screenmanager import Screen
from kivy.uix.button import Label
from kivy.lang import Builder

from version import VERSION

root = Builder.load_string('''
<MainFrame>:
    BoxLayout:
        orientation: 'vertical'
        Label:
            text: 'Hola mundo!'
        Label:
            text: root.version
''')

class MainFrame(Screen):
    version = 'Version: %s' % VERSION
    def __init__(self, **kwargs):
        super(MainFrame, self).__init__(**kwargs)

class BasicApp(App):
    def build(self):
        return MainFrame()

if __name__ == '__main__':
    BasicApp().run()

version.py是

version.py is

__all__ = 'VERSION'

VERSION = '0.0.2'

和_ main _ .py是

and _main_.py is

from .source.main import BasicApp

def main():
    BasicApp().run()

if __name__ == "__main__":
    main()

我遇到的问题是，当我通过键入来运行模块时

The problem that I have is that when I run the module by typing

python -m kivy_app

在根目录中，我需要添加行

in the root directory I need to have the line

from .version import VERSION

在main.py中(请注意版本之前是.").

in main.py (note there is '.' before version).

另一方面，当我从根目录构建android apk时，buildozer.spec使用以下行:

On the other hand, when I build the android apk from the root directory the buildozer.spec uses the line:

# (str) Source code where the main.py live
source.dir = ./kivy_app/source

当然，它正在调用这些行:

and of course it is invoking the lines:

if __name__ == '__main__':
     BasicApp().run()

在main.py中.

在这种情况下，将模块视为未包装在模块中，因此需要以下行:

In this case the module is treated as if it is not in a package and so needs the line:

from version import VERSION

(在这种情况下，import语句中的版本之前没有'.')

(In this case no '.' before version in the import statement)

如何解决此冲突?

推荐答案

此解决方案与将_ main _ .py复制到main.py并替换该行冲突:

The solution to this conflict it to copy _main_.py to main.py and to replace the line:

from .source.main import BasicApp

具有:

from source.main import BasicApp

在buildozer.spec中替换:

In buildozer.spec replace:

source.dir = ./kivy_app/source

具有:

source.dir = ./kivy_app

树现在是:

.
├── bin
│   ├── kivy_test-0.1-debug.apk
│   └── myapp-0.1-debug.apk
├── buildozer.spec
├── __init__.py
└── kivy_app
    ├── __init__.py
    ├── __main__.py
    ├── main.py
    └── source
        ├── main.py
        └── version.py
