Use application or activity context in CookieSyncManager.createInstance

Is it a good idea to use application context instead of activity context in CookieSyncManager.createInstance() call?

CookieSyncManager.createInstance(activity.getApplicationContext());

In Facebook's SDK, it uses activity context, which I think will cause memory leak:

CookieSyncManager.createInstance(activity);

So I decided to change it to CookieSyncManager.createInstance(activity.getApplicationContext());

Is there any problem of using application context in this case?

Old question, but I was just looking for the same thing.

Turns out it doesn't matter what Context you provide it in createInstance() because internally it just takes the provided context and calls getApplicationContext() on it. So either way it will end up using the application-context. Here's the source code.

I was curious about this because I wasn't sure if the CookieSyncManager class would sync/save all cookies in the entire App, or just those in the Activity that created it (if you only provided an activity-context instead of application-context). But even after knowing it's using the application-context internally, I'm still not sure about this.

I really wish the documentation would be more clear about what context-level they want/expect.
