Is it suitable doing facebook object static?

Permissions are associated with a particular Facebook App (you pass the App ID and App Key to the Android Facebook SDK). Hence, if you use the same Facebook App details in both activities, they both will be having the same permissions.

Peace be upon you,

Acquiring friends' info requires curtain permissions. e.g.

session.requestNewReadPermissions(new NewPermissionsRequest(FacebookLogin.this, Arrays.asList("friends_birthday", ...)));

However, publishing requires different permissions. e.g. session.requestNewPublishPermissions(new NewPermissionsRequest(FacebookLogin.this, Arrays.asList("publish_actions")));

I recommend that you ask for permissions on need basis. e.g. by adding permission request command in the implementation of a Button.
