Proyecto final de programación para móviles

Hola aquí está mi proyecto final de programación para móviles.

La aplicación consiste en que el servidor le manda al cliente una cadena que contiene notas musicales, solamente las mayores y las sostenidas (do do# re re# mi fa fa# sol sol# la la# si). El cliente utilizando las teclas del celular (la tecla 1 siendo do y asi en adelante hasta la tecla#) debe de marcar las notas enviadas por el servidor, la pantalla del cliente cuenta con un pequeño diagrama de un teclado, en donde se marca la "nota" que se esta tocando, a su vez la nota tocada se muestra en una cadena, por último cabe mencionar que cuando el cliente toca las notas, estas suenan en el celular. Si las notas tocadas por el cliente son las mismas que pide el servidor se "gana" el "juego".

El código fuente se encuentra abajo.
