java - android google guice框架时生成No class def found错误

Question

我在我的 Android 应用程序中使用 Guice 依赖注入(inject)框架。当我运行我的应用程序时，我收到模块类的 NoClassDefFoundError 错误。

import com.google.inject.AbstractModule;
import com.pps.data.services.UserService;
import com.pps.data.services.IService;

public class DataModule extends AbstractModule{

        public void configure ()
        {
            bind (IService.class).to(UserService.class);
        }

}//end dataModule class

 public class DataManager {
  private static DataManager instance;
   private DataModule module;

/*
 * Default constructor Singleton Pattern
 */
private DataManager ()
{
    module = new DataModule ();
}//end constructor



/**
 * Gets instance of DataManager class
 * @author Mario Dennis
 * @return
 */
public static DataManager getInstance ()
{
    if (instance == null)
    {
        instance = new DataManager ();
        return instance;
    }
    else
        return instance;
}//end getInstance method



@SuppressWarnings({ "unchecked", "rawtypes" })
public <T> List<T> getAll (Class object)
{
    Injector inject = Guice.createInjector(module);
    IService<T> service = (IService<T>) inject.getBinding(object.getClass());

    return service.getAll();    
}
}//end DataManager class

我该如何解决这个问题，还是我无法使用 Guice 框架进行 Android 开发？

Answer 1

如果您在运行时遇到 NoClassDefFoundError ，那么我怀疑您没有在运行时包含 .jar 文件。您必须选中每个 .jar 的复选框，如下所示:
