How to write files from Android to PC and back?
<p><strong>The Situation:</strong><br>
Client has an Android phone that is not activated to use cellular services and his office does not have wifi.  He wants me to write him a simple customized contact list that he can view the names and the phone numbers of people(already completed).  However, he wants a Desktop Client (done in Java) where he can update the contacts, as he is a bit older and prefers using a standard sized keyboard instead of the slider keyboard on his phone.(this is completed as well).</p>

<p>I need to complete a class for the app that will read a file on the PC's local hard drive and update the contacts file on the SD card.</p>

<p><strong>Options:</strong><br>
As far as I can tell, my only option in this case would be to use the USB port from the phone. I will have the desktop client write the contacts file to the SD card on the Android Device.</p>

<p><strong>Question:</strong><br>
Can I use the USBManager class to have the app:<br>
1. Look for xml contact file on PC.<br>
2. Read the file on the PC and update the file on the SD card.</p>

<p><strong>Additional Information:</strong><br>
Client's Phone Model: Motorola Droid II Global<br>
Android OS version: 2.3.4</p>

<p>Perhaps it may be easier to have the Desktop Client access the SDCard and write the files to the Android Device.  I am willing to review all concepts and ideas about this process.  Thank you.</p>
