Archivo de texto adjunto de Android

Estoy tratando de grabar la hora de despertar y el tiempo de sueño de un selector de diálogo a un archivo de texto como este, pero la llamada al método commitToFile2 no agrega el archivo de texto "savedData.txt".

Sé que este código es muy, muy sucio. Soy nuevo en Java por lo que cualquier otra sugerencia sería muy apreciada.

• Android Ver agregar niño
• ¿Cómo mostrar un cuadro de edición de texto "sobre" la pantalla?
• Texto de vista de texto de android en dirección vertical
• QPushButton ha duplicado texto después de la actualización Qt
• ¿Cómo lo hicieron? Diálogos sobre la pantalla de inicio
