小贝子编程

在桌面和移动端使用GraalVM加载和播放音频



我正在尝试加载和播放AudioClip在2个场景:

  1. 在开发过程中的桌面(从IDE)，以便我可以在开发过程中测试事情是否正常工作。
  2. 移动端，使用Gluon的GraalVM原生解决方案。

媒体模块在Android上不支持，使用Attach的音频服务。

我所尝试的:检查AudioService是否存在;如果是，请加载声音并与服务一起播放;如果没有，请加载声音并使用Media播放。

  • 这个方法正确吗?我得到一个异常，如下所示。
  • 我(我可以)排除媒体模块依赖时，我部署到移动设备，因为它是不可用的?

示例类:

package com.audioTest;
import static com.gluonhq.charm.glisten.application.AppManager.*;
import javafx.application.Application;
import javafx.scene.control.Button;
import javafx.stage.Stage;
import com.gluonhq.charm.glisten.application.AppManager;
import com.gluonhq.charm.glisten.mvc.View;
public class MyApplication extends Application {
AppManager appManager = AppManager.initialize();
@Override
public void init() {
class HomeView extends View {

HomeView() {
var button = new Button("Play Sound");
button.setOnAction(e -> Notifier.create());
setCenter(button);
}
};
appManager.addViewFactory(HOME_VIEW, HomeView::new);
}
@Override
public void start(Stage stage) throws Exception {
appManager.start(stage);
if (com.gluonhq.attach.util.Platform.isDesktop()) {
stage.setHeight(600);
stage.setWidth(360);
stage.centerOnScreen();
}
}
public static void main(String args[]) {
launch(args);
}
}

package com.audioTest;
import javafx.scene.media.AudioClip;
import com.gluonhq.attach.audio.Audio;
import com.gluonhq.attach.audio.AudioService;
public abstract sealed class Notifier {
public static Notifier create() {
return AudioService.create().<Notifier>map(MobileNotifier::new).orElseGet(DesktopNotifier::new);
}
private Notifier() {}
private final static class MobileNotifier extends Notifier {
private final Audio BEEP;
private MobileNotifier(AudioService service) {
BEEP = service.loadSound(getClass().getResource("/sounds/Beep.wav")).orElseThrow(); // throws here
BEEP.play();
}
}
private final static class DesktopNotifier extends Notifier {
private static final AudioClip BEEP = new AudioClip(Notifier.class.getResource("/sounds/Beep.wav").toExternalForm());
private DesktopNotifier() {
BEEP.play();
}
}
}

这个pom是Gluon插件添加的音频服务和资源列表给出的标准pom:

这是一个很好的方法。不需要更改Media模块依赖项中的任何内容，因为它不会在具有Attach服务的移动设备上使用。

对于不自动支持的每个资源，都需要在<resourceList>中声明，这也是错误的来源。它需要指定一个路径，只有当文件直接在resources文件夹下时，才可以指定<item>Beep.wav</item>。要查找该文件，需要使用以下模式:<item>.*/Beep.wav$</item>.
