removePreferencesFromCache(context: Context, options: Options, callback: AsyncCallback&lt;void&gt;): void
从缓存中移出指定的Preferences实例，此为同步接口。
从缓存中移出指定的Preferences实例，使用callback异步回调。
应用首次调用[getPreferences](#data_preferencesgetpreferences)接口获取某个Preferences实例后，该实例会被会被缓存起来，后续再次[getPreferences](#data_preferencesgetpreferences)时不会再次从持久化文件中读取，直接从缓存中获取Preferences实例。调用此接口移出缓存中的实例之后，再次getPreferences将会重新读取持久化文件，生成新的Preferences实例。
