How to emulate GPS location in the Android Emulato

Question

I want to get longitude and latitude in Android emulator for testing.

Can any one guide me how to achieve this?

How do I set the location of the emulator to a test position?

Answer 1

I was looking for a better way to set the emulator's GPS coordinates than using geo fix and manually determining the specific latitude and longitude coordinates.

Unable to find anything, I put together a little program that uses GWT and the Google Maps API to launch a browser-based map tool to set the GPS location in the emulator:

android-gps-emulator

Hopefully it can be of use to help others who will undoubtedly stumble across this difficulty/question as well.

Answer 2

The following solution worked for me - open command line and write:

adb emu geo fix [longtitude] [latitude]

Can't comment yet, so updating @ectomorphs answer here, which when telneting now requires to have an auth token. In linux that's under /home/username/.emulator_console_auth_token

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
import telnetlib
from time import sleep
import random

FILE = open('/home/username/.emulator_console_auth_token', 'r')
AUTH_TOKEN = FILE.read()
FILE.close()

HOST = "127.0.0.1"
PORT = 5554
TIMEOUT = 10
LAT_SRC = 52.5243700
LNG_SRC = 13.4105300
LAT_DST = 53.5753200
LNG_DST = 10.0153400
SECONDS = 120

LAT_MAX_STEP = ((max(LAT_DST, LAT_SRC) - min(LAT_DST, LAT_SRC)) / SECONDS) * 2
LNG_MAX_STEP = ((max(LNG_DST, LNG_SRC) - min(LNG_DST, LNG_SRC)) / SECONDS) * 2

DIRECTION_LAT = 1 if LAT_DST - LAT_SRC > 0 else -1
DIRECTION_LNG = 1 if LNG_DST - LNG_SRC > 0 else -1

lat = LAT_SRC
lng = LNG_SRC

tn = telnetlib.Telnet(HOST, PORT, TIMEOUT)
tn.set_debuglevel(9)
tn.read_until("OK", 5)

tn.write("auth {0}\n".format(AUTH_TOKEN))
tn.read_until("OK", 5)

tn.read_until("OK", 5)

tn.write("geo fix {0} {1}\n".format(LNG_SRC, LAT_SRC))
#tn.write("exit\n")

for i in range(SECONDS):
    lat += round(random.uniform(0, LAT_MAX_STEP), 7) * DIRECTION_LAT
    lng += round(random.uniform(0, LNG_MAX_STEP), 7) * DIRECTION_LNG

    #tn.read_until("OK", 5)
    tn.write("geo fix {0} {1}\n".format(lng, lat))
    #tn.write("exit\n")
    sleep(1)

tn.write("geo fix {0} {1}\n".format(LNG_DST, LAT_DST))
tn.write("exit\n")

print tn.read_all()

From a shell script one can set the coorinate like so

#!/usr/bin/env bash
export ATOKEN=`cat ~/.emulator_console_auth_token`
echo -ne "auth $ATOKEN\ngeo fix -99.133333 19.43333 2202\n"  | nc localhost 5554

Answer 4

I wrote a python script to push gps locations to the emulator via telnet. It defines a source and a destination location. There is also a time offset which lets you control how long coordinates will be pushed to the device. One location is beeing pushed once a second.

In the example below the script moves from Berlin to Hamburg in 120 seconds. One step/gps location per second with random distances.

#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys
import telnetlib
from time import sleep
import random

HOST = "127.0.0.1"
PORT = 5554
TIMEOUT = 10
LAT_SRC = 52.5243700
LNG_SRC = 13.4105300
LAT_DST = 53.5753200
LNG_DST = 10.0153400
SECONDS = 120

LAT_MAX_STEP = ((max(LAT_DST, LAT_SRC) - min(LAT_DST, LAT_SRC)) / SECONDS) * 2
LNG_MAX_STEP = ((max(LNG_DST, LNG_SRC) - min(LNG_DST, LNG_SRC)) / SECONDS) * 2

DIRECTION_LAT = 1 if LAT_DST - LAT_SRC > 0 else -1
DIRECTION_LNG = 1 if LNG_DST - LNG_SRC > 0 else -1

lat = LAT_SRC
lng = LNG_SRC

tn = telnetlib.Telnet(HOST, PORT, TIMEOUT)
tn.set_debuglevel(9)
tn.read_until("OK", 5)

tn.write("geo fix {0} {1}\n".format(LNG_SRC, LAT_SRC))
#tn.write("exit\n")

for i in range(SECONDS):
    lat += round(random.uniform(0, LAT_MAX_STEP), 7) * DIRECTION_LAT
    lng += round(random.uniform(0, LNG_MAX_STEP), 7) * DIRECTION_LNG

    #tn.read_until("OK", 5)
    tn.write("geo fix {0} {1}\n".format(lng, lat))
    #tn.write("exit\n")
    sleep(1)

tn.write("geo fix {0} {1}\n".format(LNG_DST, LAT_DST))
tn.write("exit\n")

print tn.read_all()

Answer 5

There is a plugin for Android Studio called “Mock Location Plugin”. You can emulate multiple points with this plugin. You can find a detailed manual of use in this link: Android Studio. Simulate multiple GPS points with Mock Location Plugin

Answer 6

Dalvik Debug Monitor > Select Emulator > Emulator Control Tab > Location Controls.

DDMS -- android_sdk/tools/ddms OR android_sdk/tools/monitor
