Method Detail

getProfileImage

ProfileImage getProfileImage(String userUuid,
                             ProfilePreferences prefs,
                             ProfilePrivacy privacy,
                             int size)

Get the profile image for a user. Takes into account all global settings, user preferences and privacy.

If making a request for your own image

• 'privacy' can be null as it won't be considered.
• You should provide 'prefs' (if available) otherwise it will be looked up.

If making a request for someone else's image

• You should provide the privacy settings for that user (if available), otherwise it will be looked up.
• You should provide the preferences object for that user (if available), otherwise it will be looked up.
• If privacy is null, a default image will be returned
• If preferences is still null, the global preference will be used, which may not exist and therefore be default.

The returned ProfileImage object is a wrapper around all of the types of image that can be set. use the getBinarty and getUrl() methods on this object to get the data. See the docs on ProfileImage for how to use this.

userUuid -

prefs -
