java - Android Studio Android Projekt 独立运行 Java

Question

您好，我编写了一个 Android 应用程序，但该应用程序的某些部分包含应该在桌面上运行的 native 桌面 Java 代码，现在我可以在 Android Studio 中运行它并且它可以工作，提供了 Android 库作为“ stub ”，但我想导出它并使其在没有android studio的情况下可以运行。但我完全不知道从哪里开始。我不想创建 Java 模块，因为这多次破坏了我的应用程序。任何想法？我知道将 Desktop-Java 与 Android 混合使用是糟糕的设计，但无论如何我都需要 Android-App 的几乎所有 Desktop-Java 代码。

只需将运行行复制到 windows-cmd 中，即使没有 Android studio 也能正常工作，但我认为这不会在我的电脑以外的任何其他运行时环境中运行。

Answer 1

我是这样做的:

将所有核心代码放入带有 gradle 构建文件的桌面项目中。将桌面内容放入另一个桌面项目中。将 android 特定的东西放入 android studio 中。在每个其他项目中使用核心项目构建的 jar。

一个额外的好处是它使核心代码的单元测试非常容易。

请参阅下面的示例。 Android版本必须设置回调。

interface Factory {
    Audio create();
    class FactoryImpl implements Factory {
        private FactoryImpl() {}
        @Override public Audio create() {
            return isAndroid()?new AndroidAudio():new WindowsAudio();
        }
        public static class AndroidAudio implements Audio {
            AndroidAudio() {}
            @Override public void play(Sound sound) {
                if(Audio.Instance.sound) if(consumer!=null) consumer.accept(sound);
                else l.severe("callback is not set: "+sound);
            }
            public void setCallback(Consumer<Sound> consumer) {
                this.consumer=consumer;
            }
            public Consumer<Sound> consumer;
        }
        private static class WindowsAudio implements Audio {
            WindowsAudio() {}
            @Override public void play(final Sound sound) {
                if(Audio.Instance.sound) try {
                    String filename=sound.name()+".wav";
                    l.info("play: "+filename);
                    Clip clip=AudioSystem.getClip();
                    AudioInputStream inputStream=AudioSystem.getAudioInputStream(new BufferedInputStream(Audio.class.getResourceAsStream(filename)));
                    if(inputStream!=null) {
                        clip.open(inputStream);
                        FloatControl gainControl=(FloatControl)clip.getControl(FloatControl.Type.MASTER_GAIN);
                        gainControl.setValue(-25.0f); // ?
                        clip.start();
                        // maybe do not wait?
                        while(clip.getMicrosecondLength()!=clip.getMicrosecondPosition())
                            Thread.sleep(1); // wait
                        // or at least don't wait here?
                        //Thread.sleep(500);
                        clip.close();
                    } else l.warning("input stream is null!");
                } catch(Exception e) {
                    e.printStackTrace();
                    l.severe("caught: "+e);
                    l.severe("failed to play: "+sound);
                }
            }
        }
    } }
