方法名：getSingletons

Application.getSingletons介绍

[英]Get a set of root resource, provider and Feature instances. Fields and properties of returned instances are injected with their declared dependencies (see Context) by the runtime prior to use.

Implementations should warn about and ignore classes that do not conform to the requirements of root resource or provider classes. Implementations should flag an error if the returned set includes more than one instance of the same class. Implementations MUST NOT modify the returned set.

The default implementation returns an empty set.
[中]获取一组根资源、提供程序和功能实例。返回实例的字段和属性在使用前由运行时注入其声明的依赖项（请参见上下文）。
实现应该警告并忽略不符合根资源或提供程序类要求的类。如果返回的集合包含同一类的多个实例，则实现应标记错误。实现不能修改返回的集。
默认实现返回一个空集。
