JavaFX Shape3D objects not working on Android phone

Question

I can't get Shape3D objects such as a simple Sphere or MeshView to work on my Android phone. I have used Gluon plugin for NetBeans 8.0.2 to create small apps for my phone and this is the first time I am using Shape3D objects.

import javafx.application.Application;
import javafx.geometry.Rectangle2D;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.shape.Sphere;
import javafx.stage.Screen;
import javafx.stage.Stage;

public class testGluonApp extends Application {

    @Override
    public void start(Stage stage) throws Exception {

        Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
        double width = visualBounds.getWidth();
        double height = visualBounds.getHeight();

        Sphere sphere = new Sphere(64.0);

        StackPane stackPane = new StackPane();
        stackPane.getChildren().addAll(sphere);

        Scene scene = new Scene(stackPane, visualBounds.getWidth(), visualBounds.getHeight());

        stage.setScene(scene);
        stage.show();
    }

}

The sample application above ( from javafxports samples ) works fine on my PC but when I compile the app (Tasks->android->android) and install it on my device (Tasks->android->androidInstall) it does install but only shows a black screen when started up.

I MQoS    : MSG_QUERY_TCP_INFO called,count:2174

This is what I got from adb logcat ( thanks for the instructions how to get it from a device ). I do not know how to go around solving this. I can't find any methods involving shaders or any info about Shape3D object shaders which seem to be causing the problem.

I noticed that the build.gradle for the sample program had ''jfxmobile-plugin:1.0.6'' by default. I changed this to 1.0.7 but the problem still persists. The ''main'' project had 1.0.7 in the build.gradle all along. Updated with a new stacktrace in case of changes due to the change to 1.0.7.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.7'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

mainClassName = 'com.gluonapplication3.GluonApplication3'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        androidSdk = 'dirHavingSDK/AndroidSDK'
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
    }
}

Answer 1

JavaFX3D works on Android using JavaFXPorts, as you can see here.

If you find a black screen, first you need to find out what could be the reason. Usually, depending on the type of device, memory could be an issue.

With your mobile connected to your PC, and with debugging options enabled (go to Settings, Developer options, set USB debugging enabled), go to command line and run:

adb logcat -v threadtime

Now run your app and try to find in the output an exception.

If you happen to find a java.lang.StackOverflowError check this answer for a solution, apply it and try again.

Other issue you may find is that your device doesn't support 3D conditional feature.

For other cases, try to solve it or post the relevant parts so we can help.

EDIT

Based on the stacktrace posted by the OP, the exception shows a problem that has been reported when updating from Android 5.1.1 to 6.0, since the latest drivers on Android are much more strict in compiling shaders.

A fix for this issue has been already created here, and will be available with the javafxports version 8.60.7.
