[android-developers] Newbie seeking design suggestions

Hello to the group from an Android newbie. I have considerable experience in software design and coding (including Java), but none with Android. I have, however, read the setup info, and have a good idea how to get started.

I want to develop an app that has the ability to receive text messages from a host application (probably written C#.Net) on my home network, and present that text in a particular "pretty picture" format to the user. I also need the ability for the user to press a button to signal to the host user that the message was received. I can think of several ways to accomplish this, and would like to hear comments and suggestions on these or others.

1. Shared files. The host could write a text or XML file to my Linux server running NFS and Samba, and the Android app could detect its presence and read it. To respond, the app could write a similar file for the host to read.

2. Use a MySQL database to pass data instead of the files in #1. I have MySQL running on my Linux server. Can an Android app connect to MySQL?

3. Use network sockets. I have written a socket server in C that runs on Linux, for a different application, and a socket client in C#.Net. Could sockets be used on an Android?

Does anyone have comments on these approaches, or whether there is something better?

One more question: Is it possible for an Android app to send/receive real-time voice over the network?

Thanks in advance for any information.
