Pyjnius 导入 jar 文件

2022-01-15 00:00:00 python kivy pyjnius

问题描述

Pyjnius 允许您为 java 类创建一个 python 包装器，例如:

Pyjnius allows you to create a python wrapper for java classes like:

Hardware = autoclass('org.myapp.Hardware')

有没有办法像这样导入现有的 *.jar 文件?语法是什么样的?

Is there a way to import an existing *.jar file like that? What does the syntax look like?

解决方案

jar文件只与android相关，你需要在你的buildozer.spec中添加jar文件

As much as jar file relevant only for android, you need to add jar file in your buildozer.spec like

android.add_jars = java/myjar.jar

在您应用的 build 方法中

from kivy.utils import platform
...
if platform() == 'android':
    BlaClass = autoclass('java.bla.BlaClass')
...
