Question

我尝试在Android中运行以下代码：

final GroovyClassLoader classLoader = new GroovyClassLoader();

final StringBuilder groovyScript = new StringBuilder();
groovyScript.append("class Sample {");
groovyScript.append("String sayIt(){\"Groovy says: Cool!\"}");
groovyScript.append("}");

Class groovy = classLoader.parseClass(groovyScript.toString());
GroovyObject groovyObj = null;
try {
      groovyObj = (GroovyObject) groovy.newInstance();
} catch (InstantiationException ex) {
      Logger.getLogger(MainApplication.class.getName()).log(Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
      Logger.getLogger(MainApplication.class.getName()).log(Level.SEVERE, null, ex);
}
String output = (String) groovyObj.invokeMethod("sayIt", null);

但不幸的是它引发了一个错误：

我试图在Android中运行 Groovy 而我几乎就在那里！顺便说一句，我遵循了本教程：Creating Android Apps with Groovy 2.4

AndroidRuntime：类生成期间的一般错误：无法加载此类类文件
