GPS signals and cellular or Wi-Fi network
The biggest disadvantage to geocaching with an android is the fact that, unlike a handheld gps your android is not waterproof or durable. As a geocacher myself I can assure you, you will drop your gps device sooner or later. If you really want to try geocaching with your android go ahead and just be very careful! If you decide that you really want to continue geocaching then I highly recommend that you buy a real geocaching gps. An entry level gps can be purchased for around $50!
