I try to this follow how-to-emulate-gps-location-in-the-android-emulator.

1st. get the serials number of the emulator.

>adb devices

It not work. However when I send gps info manually in eclipse(ADT22.6), it works. My app can locate the location correctly. What did eclipse do? How to make the adb command work? Thanks

Answer 1

Have you try sending it via telnet? First you have to connect to the emulator:

telnet localhost 5554

Then you can use the geo command to send latitude and logitude:

geo fix 121.4961236714487 31.24010934431376
