将JavaFX应用程序转换为Android APK - HTML文件加载谷歌地图的问题

标签： android javafx apk javafxports gluon-mobile

我正在尝试将用JavaFX编写的应用程序移植到Android上，并且在大多数情况下，我的尝试都取得了成功。在使用Netbeans IDE和Gradle打包apk文件后，应用程序将在Android上运行。

但我遇到的问题是，当尝试通过JavaFX Webview组件访问谷歌地图时，应用程序将崩溃。我正在使用的是JavaFX中的以下内容：

html文件位于Gradle根文件夹的资源文件夹下。

当我在Netbeans中测试应用程序时，右键单击Gradle根节点并选择Tasks - ＆gt;运行 - ＆gt;跑。我的应用程序运行完美，包括使用html文件和JavaFX Webview访问谷歌地图。

创建apk文件也成功使用了任务 - ＆gt; Android - ＆gt; Android系统。但是，一旦我在Android设备上安装apk文件并访问我的应用程序的谷歌地图部分，它就会让我退出应用程序 说“不幸已停止”。关于如何解决这个问题的任何线索？

查看使用adb命令创建的日志文件，我看到了以下输出：

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

apply plugin: 'org.javafxports.jfxmobile'

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

mainClassName = 'com.SundaeThePugApp.SundaeThePugFX'

dependencies {
    compile 'com.gluonhq:charm:2.1.0'

    androidRuntime 'com.gluonhq:charm-android:2.1.0'
    iosRuntime 'com.gluonhq:charm-ios:2.1.0'
    desktopRuntime 'com.gluonhq:charm-desktop:2.1.0'
}

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        androidSdk = 'C:/Users/Zermatt/AppData/Local/Android/android-sdk/'
    }
}

这是build.gradle文件，是的，我使用的是Verdana字体。但是从我在Android设备上看到的字体就可以了。

URL resource= getClass().getClassLoader().getResource("Music/ThemeMusic.mp3");
        themeSong = new MediaPlayer(new Media(resource.toString()));
        themeSong.setOnEndOfMedia(new Runnable()
        {   public void run()
            {   themeSong.seek(Duration.ZERO);
            }
        });
        themeSong.play();

修改

找到致命异常的原因。看起来Android不喜欢以下代码块：

googleMapEngine.load(getClass().getResource("/googleLondonMap.html").toExternalForm());

此代码块在Android中出现错误消息：

String url = createAndroidURLScheme("/googleTestMap.html");
//System.out.println(url);
googleMapEngine.loadContent(url, "text/html");
googleMapEngine.setJavaScriptEnabled(true);
                googleMapEngine.getLoadWorker().stateProperty().addListener(new ChangeListener<Worker.State>()
                {   public void changed(final ObservableValue<? extends Worker.State> observableValue, final State oldState, final State newState)
                    {   if (newState == State.SUCCEEDED)
                        {   googleMapEngine.executeScript(
                                "var latlng = new google.maps.LatLng(59.438722, 24.745278);" +
                                "var myOptions = {" + 
                                "zoom: 15," +
                                "center: latlng," +
                                "mapTypeId: google.maps.MapTypeId.ROADMAP," +
                                "mapTypeControl: false," +
                                "navigationControl: false," +
                                "streetViewControl: false," +
                                "backgroundColor: '#666970'," +
                                "disableDefaultUI: true" +
                                "};" +
                                "" +
                                "var map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);");
                        }
                    }
                });

网页不可用： jar的网页：file：/data/app/com.SundaeThePugApp - 1 / base .apk！/googleLondonMap.html 无法加载，因为：

净:: ERR_UNKNOWN_URL_SCHEME

所以我现在可以做些什么来纠正这个问题？

再次编辑

尝试使用Jose解决方案并在其基础上进行构建，我发现了一种在Html中使用JavaScript的方法，尽管它并不漂亮。基本上他提供的代码我放入一个方法（称为createAndroidURLScheme）并返回一个字符串。这是代码，是的，它在JavaFX中工作正常，但在Androids webview中再次没有：

现在通过logcat我得到了这个新的Android Fatal Exception：

{{1}}

我现在可以做些什么来缓解这种情况并让Androids Webview感到高兴？
