如果要在此方法中使用它，如何从构造函数中获取应用程序？

Answer 1

如果添加private val application，则会在编译时出现异常，例如

Accidental override: The following declarations have the same JVM signature

因此，要解决此问题，只应在需要的地方调用 getApplication()。

SearchRecentSuggestions(getApplication(), MySuggestionsProvider.AUTHORITY, MySuggestionsProvider.MODE).clearHistory()
