我正在jfxmobile-plugin的帮助下在Android上测试JavaFX。尝试在我的android设备上运行它时遇到性能问题。我曾见过类似的问题，但它似乎在2018年仍未解决。有人发布了this question，三年后仍未解决。
这就是我用来构建项目的方式：
GluonApplication.Java
package com.gluonapplication;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.geometry.Rectangle2D;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class GluonApplication extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
FXMLLoader loader = new FXMLLoader(getClass().getResource("/Dashboard.fxml"));
Parent root = loader.load();
Rectangle2D r = javafx.stage.Screen.getPrimary().getVisualBounds();
Scene s = new Scene(root,r.getWidth(),r.getHeight());
primaryStage.setScene(s);
primaryStage.show();
}
}

当我触摸屏幕时，我会看到很多文本输入到logcat，我认为这可能会使应用程序更加缓慢。因此，我尝试使用proguard（build.gradle上的proguardFile）删除调试调用，但是我在此任务上没有成功，它没有对最终apk进行任何更改。
我尝试在Android 4.4以及Android 6和Android 8上运行该应用程序。所有这些在滚动时都很慢。有人有想法来改善这一点，并使JavaFX在2018年可在Android设备上使用吗？
