The difference between commit() and apply()

We might be confused by those two terms, when we are using SharedPreference. Basically they are probably the same, so let’s clarify the differences of commit() and apply().

1.Return value:

apply() commits without returning a boolean indicating success or failure. commit() returns true if the save works, false otherwise.

2. Speed:

apply() is faster. commit() is slower.

3. Asynchronous v.s. Synchronous:

apply(): Asynchronous commit(): Synchronous

4. Atomic:

apply(): atomic commit(): atomic

5. Error notification:

apply(): No commit(): Yes
