"The first line of code" Android features development, based on location services, problems arise

Mobile phone GPS positioning is slow, high precision, more power consumption, network positioning faster, low precision, less power consumption

When the position accuracy is very high, use GPS to locate, in general, use the network location.

According to the first line of code to write a positioning program, the real machine has no location information output, but the simulator has output.

Finally found the problem, the mobile phone positioning mode to the mobile network positioning, rather than GPS positioning, positioning information will be displayed immediately.
