Changes to a android app

1) If the user haven't set the for id1, id2 or id3. Prompt them with the message "Please set this id in the settings menu" 2) When the user sets the id, add a space after their id (eg. User enter "ABC123", save the id as "ABC123 "). If the user already add a space after their id, then no need to add the space. 3) Help me update the app icon with the attached png image. ( Will provide soon)
