我想执行一个脚本。所以我从
添加了JavaScript引擎http://www.java2s.com/Code/JarDownload/jsr223/jsr223.jar.zip
我的gradle(模块:app)说:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.google.apis:google-api-services-youtube:v3-rev162-1.21.0'
compile 'joda-time:joda-time:2.3'
compile files('libs/jsr223.jar')
}
如果我正在运行应用程序并单击初始化脚本引擎的按钮,则会出现以下错误。
任何想法如何解决?

答案 0 :(得分:2)
您正在导入sun.misc.service。我想你可能是指android.app.Service。因此,您无法加载它(android不包括sun.misc.Service)。或者您需要将其与您的应用打包。
