[JAVA] J'ai essayé de me permettre de définir le délai pour le client Android UDP

Changements depuis la dernière fois

Dans le programme précédent, le temps de retard était réglé à 500 millisecondes, mais lors de la mesure de la valeur du capteur d'accélération, il a été amélioré afin que le retard puisse être ajusté par vous-même afin de raccourcir le temps de retard lors de la détection de mouvement. ..
