building/hacking/...

Checkout this repo in Android studio, wait for gradle sync to finish (you might need to install missing android-21 target) and click "build" :)

Just click "Run" and choose a running device (requires "USB debugging" enabled)..

Alternatively, you can use "Build/Build APK" to build an unsigned APK so you can copy and install this APK on your phone (requires allowed "Unknown sources").

basic usage

Start the application, click "start" and telnet to the IP address of your android device on the specified port (default 5554) and you can mock locations exactly the same as with the android emulator:

$ telnet my_phone_ip 5554
Trying my_phone_ip...
Connected to my_phone_ip.
Escape character is '^]'.
MockGeoFix: type 'help' for a list of commands
OK
geo fix 50 50
OK
geo nmea $GPRMC,081836,A,3751.65,S,14507.36,E,000.0,60.0,130998,011.3,E*51
OK

helper scripts

run_sim.py

helper_scripts/run_sim.py loads a GPX file and replays it sending "geo fix" commands. This script also supports optional live visualization of the simulated route in a web browser.

examples

  1. run MockGeoFix on your phone and click "start"
  2. run ./run_sim.py -i <your_phone_ip> -g your_gpx_file.gpx on your computer

with web visualization ...

  1. run MockGeoFix on your phone
  2. run ./run_sim.py -i <your_phone_ip> -g your_gpx_file.gpx -I 127.0.0.1 -P 8080 -s 20
  • NOTE: -s 20 will simulate 20km/h speed
  1. open http://127.0.0.1:8080 in your web browser

helper_scripts/run_sim.py --help for more info

NOTE: You can use http://www.gpsvisualizer.com/convert_input to convert directions from google maps to GPX (just copy the URL from google maps to the 'Or provide the URL of a file on the Web: ' field in gpsvisualizer converter). Alternatively, simply export GPX from http://map.project-osrm.org/ .

run_json_proxy.py

helper_scripts/run_json_proxy.py provides a simple js application with a map you can use to set the mock location. run helper_scripts/run_json_proxy.py --help for more info

extra tricks

where to get APKs

If you can't/don't want to install MockGeoFix from Google Play, you can download APKs directly from the Releases page.

forwarding geo commands sent to the emulator to a real device

tcpflow -B -C -i lo dst port 5554 | socat - TCP4:my_phone_ip:5554

running MockGeoFix in the emulator

It's possible to run mockgeofix in the emulator as well (this seems a bit "wtf" but it can be useful when the "geo fix" functionality in the emulator just does not work):

adb -e forward tcp:5556 tcp:5554

and then simply

telnet 127.0.0.1 5556

this can then be combined with tcpflow and socat to forward "geo commands"

tcpflow -B -C -i lo dst port 5554 | socat - TCP4:127.0.0.1:5556
