Javafx 当用模拟器测试时，Gluon android apk会产生一个黑屏

然而，我遵循了gluon mobile android安装教程，在创建apk并在模拟器上运行时，会出现一个黑屏，基本上会使应用程序崩溃。这是当前我的build.gradle：

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'org.javafxports:jfxmobile-plugin:1.3.10'
    classpath 'com.google.gms:google-services:3.1.0'
}
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
jcenter()
maven {
    url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
mavenCentral()
}

mainClassName = 'com.gluonapplication.GluonApplication'

}
