我想创建一个使用MySqlDB连接的app / desktopapp.
我在Netbeans中使用了Gluon插件.当我想编译桌面应用程序时,一切正常.但是,当我想为Android编译应用程序时 – >它崩溃了

谢谢,我希望你能帮助我.

解决方法:

我尝试过使用最新的mysql-connector驱动程序(5.1.37),并且在构建apk时遇到了同样的异常.

此异常似乎与用于编译driver的JDK的某些问题有关,而不是与Android上不支持的mysql有关.

所以在这篇文章的answer之后,我使用了旧版本的驱动程序：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.6'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

dependencies {
    compile 'mysql:mysql-connector-java:3.1.12'
}

mainClassName = 'com.gluonhq.testsql.TestSQL'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        packagingOptions {
            exclude 'META-INF/INDEX.LIST'
        }
    }
    ios {
        forceLinkClasses = [ 'com.gluonhq.**.*', 'com.mysql.**.*']
        infoPList = file('src/ios/Default-Info.plist')
    }
}

我能够构建项目并在桌面,Android和iOS上成功运行.

编辑

对于iOS,使用较新版本的驱动程序(3.1.13)会导致编码exceptions.
