How to get the current location latitude and longitude in android
Before couple of months, I created GPSTracker library to help me to get GPS locations. In case you need to view GPSTracker > getLocation

Note
If the method / answer doesn't work. You need to use the official Google Provider:

How do I get the current Latitude and Longitude of the mobile device in android using python?
In case you need to retrieve location information from connected android device you could use following script:
import sh
from re import findall
#Location[network 11.111111,11.111111 acc=24
LOCATION_PATTERN ="(\w+)\ (\d+.\d+),(\d+.\d+)\ acc"
def set_location_settings(type, on):
status = "+" if on else "-"
sh.adb("shell", "settings", "put", "secure", "location_providers_allowed", "{0}{1}".format(status, type))
def get_location_settings():
return sh.adb("shell", "settings", "get", "secure", "location_providers_allowed")
def is_location_enabled():
return bool(get_location_settings().strip())
def get_location_data():
d = dict()
for (type, lat, long) in findall(LOCATION_PATTERN, str(sh.adb("shell", "dumpsys", "location"))):
d.setdefault(type, []).append((lat, long))
return d
if not is_location_enabled():
set_location_settings("gps", True)
set_location_settings("network", True)
print get_location_settings()
print get_location_data()
It uses dumpsys in order to retrieve location information. Also it has option to switch on the gps.
The result is a dictionary of type to list of lat,long pairs:
Example output:
{
'network': [
('11.111111', '11.111111'),
('11.111111', '11.111111'),
('11.111111', '11.111111'),
],
'gps': [
('11.111111', '11.111111'),
('11.111111', '11.111111'),
('11.111111', '11.111111')
]
}

How to get Latitude and Longitude from mobile device Android
I have finally found my mistake. the example given HERE works fine.
And the mistake was mine. In the location Setting in my mobile, i forget to check the mobile networks option. once i checked tat option i got the latitude and longitude for my current location.
