所以我试图将我的一个java fx项目转换为使用胶子的Android应用程序。这是一个实现图像查看器等的场景。所以我希望所有文件都可以访问，但是无论我把文件放在哪里或放在路径上，我都无法使用媒体检测.wav我的项目中的文件。我想知道我是否可以获得一些帮助，在哪里放置我的.wav文件以及使用什么作为代码的媒体（“”）部分的URl。

答案 0 :(得分：0)
移动版JavaFX不支持媒体。有关当前支持的功能，请参阅此answer。
但这并不意味着您无法使用设备中的原生播放器。
最近，Charm Down（使用统一的，独立于平台的API访问设备及其硬件功能的开源库）添加了视频服务。
您可以看到有关如何使用它的简短帖子here。
基本上，您需要在构建中包含video插件：
// build.gradle
jfxmobile {
downConfig {
version = '3.6.0'
plugins 'display', 'lifecycle', 'statusbar', 'storage', 'video'
}
}
将音频/视频文件放在资源文件夹/src/main/resoures中，或提供有效的网址，然后您就可以使用该服务：
Services.get(VideoService.class).ifPresent(service -> {
service.getPlayList().add("myAudio.wav");
service.play();
});
音频不添加任何可见控件（MediaView），它在后台播放。您可以添加一些按钮来播放/暂停/停止音频。
