I just purchased a ZTE Cricket X500 running 2.3.4 for the purpose of testing my Android apps on. When I start the DDMS in the Eclipse Android SDK the device is not listed. The phone is in debug mode, Unknown Sources is enabled, and as far as I can tell the neccesary USB drivers have been installed. Furthermore I have a "Android Dev Phone 1" and the DDMS is able to recognizing that. My computer is running Windows 7. Any theories as to what might be going on?
try these commands:
adb kill-server
adb start-server
for some reason, this works for if the device isn't listed
