android: how to fix gps with mock(fake) coordinates?

Question

I\'m trying to fix GPS programmatically when the GPS signal is not available. I want to do this in order to provide mock coordinates to other apps like google maps and other

Answer 1

What mock locations need :

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION">

Also in the android phone settings make sure you have the "Allow mock locations" checkbox ticked

locationManager.addTestProvider(mocLocationProvider, false, false,
                    false, false, true, true, true, 0, 5);
locationManager.setTestProviderEnabled(mocLocationProvider, true);

. Now whenever you want to send a location, call this code:

Location mockLocation = new Location(mocLocationProvider); // a string
mockLocation.setLatitude(location.getLatitude());  // double 
mockLocation.setLongitude(location.getLongitude()); 
mockLocation.setAltitude(location.getAltitude()); 
mockLocation.setTime(System.currentTimeMillis()); 
locationManager.setTestProviderLocation( mocLocationProvider, mockLocation); 

.

But this works only the first time

Because you called it one time.

I have to do a service for what I want to do

You can do this, even an AsyncTask will do

do this or not: lm.requestLocationUpdates()

Yes you have to with the mocLocationProvider

I already call more times the method setLocation(latitude,longitude) but it works(location updateding) only first time for google maps

There is no method called setLocation(), use setTestLocation()

What actually I have to do in asynckTask

You can use a Thread, a TimerTask or anything you like. The idea is to inject location every second into the Framework.
