Synchroniser les données entre la base de données Android sqlite et le serveur phpmyadmin

Je veux synchroniser des données entre une application Android et un serveur mysql.

comment l'application fonctionne:

Lorsque l'application n'a pas Internet .. l'utilisateur entre les informations dans les champs et toutes les données seront enregistrées dans ma base de données sqlite.
et pour la prochaine fois que j'ai Internet je cliquera sur un bouton pour que toutes les données qui ont déjà été enregistrées dans ma base de données sqlite seront transmises à mon serveur mysql.

pouvez-vous me dire comment je peux le faire, ou partager avec moi un exemple qui fait cela? Ce serait vraiment bien si quelqu'un pouvait me montrer comment le faire ou me donner une bonne direction sur la façon de le faire.

je partagerai avec vous mon code,

DB_sqlite.java
