Local queuing

One element not found in this sample application is the local queuing of the signature. Ideally this would be done in the event that data coverage is not available. The storage of the image is actually quite simple; the perhaps more challenging piece is the logic on when to attempt to send the data again. Considering all of the development of this sample application is done on the Android Emulator with near-perfect connectivity, it is of little concern here. However, in the interest of best preparing you to write real-world applications, it is worth the reminder of local queuing in the event of communications trouble in the field.
