[JAVA] Envoyer périodiquement les valeurs du capteur d'accélération d'Android au PC via UDP

Changements depuis la dernière fois

La dernière fois, j'ai créé un programme pour envoyer la valeur lorsque vous appuyez sur le bouton Android, mais cette fois j'ai créé un programme afin que la valeur puisse être envoyée régulièrement en utilisant TimerTask.
