When I run my java fx on JVM (gradle run) everything works instead when I launch it on Android device (gradle AndroidInstall), I see a black screen, I don't have any error in console log.
My build.gradle:

```
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.9'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

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

mainClassName = 'it.wstech.talco.TAMainApplication'

dependencies {
    compile 'com.gluonhq:charm:3.0.0'

    compile fileTree(dir: '../mglib/build/libs', include: ['*.jar'])
    compile fileTree(dir: '../mglib/lib', include: ['*.jar'])
    compile fileTree(dir: '../nowapp/build/libs', include: ['*.jar'])
    compile fileTree(dir: '../nowapp/lib', include: ['*.jar'])
    compile fileTree(dir: 'lib', include: ['*.jar'])  

    androidRuntime 'com.gluonhq:charm-android:3.0.0'
    iosRuntime 'com.gluonhq:charm-ios:3.0.0'
    desktopRuntime 'com.gluonhq:charm-desktop:3.0.0'
    embeddedRuntime 'com.gluonhq:charm-desktop:3.0.0'
}

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
         androidSdk="/Users/wstechsrl/Desktop/Android/sdk"
         signingConfig {
            storeFile file('/opt/modja/workspace-fx/n_talco/softws-keystore')
            storePassword 'wstechsrl'
            keyAlias 'ws-keystore'
            keyPassword 'xxxxx'
        }

    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
        forceLinkClasses = [
                'com.gluonhq.**.*',
                'io.datafx.**.*',
                'javax.annotations.**.*',
                'javax.inject.**.*',
                'javax.json.**.*',
                'org.glassfish.json.**.*'
        ]
    }
}

```
