我是使用胶合移动的Android开发新手。
我一直在试图将Google MapView与我的Android应用程序集成，所以我用这个GMapsFX Api来构建一个Mapview。
我的问题是，应用程序在桌面上运行更流畅，但在Android设备上部署应用程序时退出。
这里的build.gradle文件，该项目
Gmapsfx集成在Android应用程序中无法正常工作使用胶合移动构建版本
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.2.0'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
mainClassName = 'com.gluonapplication.Sample'
dependencies {
compile 'com.gluonhq:charm:4.1.0'
androidRuntime 'org.sqldroid:sqldroid:1.0.3'
compileNoRetrolambda 'com.jfoenix:jfoenix:1.0.0'
compile 'com.lynden:GMapsFX:2.11.0'
}
jfxmobile {
downConfig {
version = '3.2.4'
// Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
plugins 'display', 'lifecycle', 'local-notifications', 'runtime-args', 'statusbar', 'storage'
}
android {
manifest = 'src/android/AndroidManifest.xml'
}
}
这里拥有的MapView
<?xml version="1.0" encoding="UTF-8"?>
<?import com.lynden.gmapsfx.GoogleMapView?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.control.TextField?>
<?import javafx.scene.layout.VBox?>
<VBox alignment="CENTER" prefHeight="566.0" prefWidth="353.0" spacing="10" stylesheets="@Maps.css" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.gluonapplication.views.MapController">
<children>
<Label fx:id="header" layoutX="120.0" layoutY="14.0" text="the Sacred Groves" />
<GoogleMapView fx:id="MapView" layoutX="4.0" layoutY="62.0" prefHeight="525.0" prefWidth="353.0">
<children>
<TextField prefHeight="25.0" prefWidth="173.0" promptText="Enter a Location!" />
</children></GoogleMapView>
</children>
</VBox>
这里的主类创建场景的FXML文件。

谢谢！
帮助解决这个问题对我来说一切似乎都很好，但是应用程序在开始时会退出。
但在桌面上工作正常。
我已经跑亚行logcat -v threadtime上了车CMD此输出
