Gets the current amount of time (in ms) that the tool tip will be displayed to the user.

setToolTipDisplayTime

 void setToolTipDisplayTime(long displayTime)
Sets the amount of time (in milliseconds) that the tool tip will be shown to the user. Thedefault is {@value com.facebook.login.widget.ToolTipPopup#DEFAULT_POPUP_DISPLAY_TIME}. Anyvalue that is less than or equal to zero will cause the tool tip to be displayed indefinitely.
Parameters:
displayTime - The amount of time (in milliseconds) that the tool tip will be displayed tothe user

setDefaultAudience

 void setDefaultAudience(DefaultAudience defaultAudience)
Sets the default audience to use when the user logs in. This value is only useful whenspecifying publish permissions for the native login dialog.
Parameters:

setReadPermissions

 void setReadPermissions(List<String> permissions)
Set the permissions to use when the user logs in. The permissions here can only be readpermissions. If any publish permissions are included, the login attempt by the user will fail.The LoginButton can only be associated with either read permissions or publish permissions, butnot both.
