What's the difference between commit() and apply() in SharedPreferences

Question

I am using SharedPreferences in my android app. I am using both commit() and apply() method from shared preference. When I use AVD 2.3

Answer 1

• commit() is synchronously, apply() is asynchronous

• apply() is void function.

• commit() returns true if the new values were successfully written to persistent storage.

• apply() guarantees complete before switching states , you don't need to worry about Android component lifecycles

If you dont use value returned from commit() and you're using commit() from main thread, use apply() instead of commit()
