Android Application Development (AND-401) — Question 87

Which of these is the incorrect method for an Application to save local data?

Answer options

• A. Extend PreferencesActivity and save in an XML file.
• B. Save as a file in the local file system.
• C. Save in the database using SQLite.
• D. Save in the hash table file using the Dictionary class.

Correct answer: D

Explanation

The correct answer is D because using the Dictionary class to save data in a hash table file is not a standard method for local data storage in applications. Options A, B, and C are all valid methods for storing data locally, such as using PreferencesActivity for XML files, the local file system for file storage, and SQLite for database storage.
