Please suggest me some solution

The default setting in ejabberd example config file is to limit the number of offline messages to 100.

  max_user_offline_messages: 
    admin: 5000
    all: 100

New messages will be rejected and sender will be notified with an error.

If you user is an admin but you are expecting to connect as admin from Android, you can also configured ejabberd to limit the number of offline messages for admin to 100 messages.
