You would need the Nike +IPod sport kit (#0001101) in order to make the men's Nike LunarGlide+ 4 shoe Nike+ ready. I don't believe the Droid would have the proper connections needed to utilize the device. Here are the specific download instructions off the vendor's website:
Download and Install Nike+ Connect
To install Nike+ Connect on your Mac or PC:
Go to www.nikeplus.com/setup
(will open in a new window) and click on Download Nike+ Connect.
The Nike+ Connect Installer program will open automatically.
If Nike+ Connect doesn't open automatically:
Mac- Open the downloaded Nike+Connect.dmg file, then double-click Nike+ Connect Installer.mpkg.
PC- Open the downloaded Nike+Connect_Installer.exe file.
Follow the onscreen instructions to install the Nike+ Connect software. Once installed, a new Nike+ Connect folder will appear in your hard drive and Nike+ Connect will be listed under your programs.
Plug your Nike+ device into the USB port on your computer and follow the onscreen instructions to pair your device with your Nike+ profile.
After you pair your Nike+ device with your Nike+ profile, Nike+ Connect will launch automatically anytime you connect your device to your computer.
