Location updates not working indoors as claimed by Fusion Location Provider APIs

Question

Issue:

Location updates not working indoors as claimed by Fusion Location Provider APIs.

What happened:

1. I tried implementing the latest location API to get location updates using LocationClient in my Android App.
2. My android app works fine with out any issue while I am testing outdoor.
3. But when testing indoors (inside any building), then no location updates are happening.

Expected behavior:

As per the new APIs, I am expecting to get some estimated location around the building while I am indoors (as GPS do not find the satellite signal for accurate location).

I see that latest Google Maps android app works fine indoors with estimated location.

Question:

What else do I have to take care using new location APIs to get the location update indoors (accurate location is not required, low accuracy is also fine).

I am implementing the Android App using Android 4.2.2 version APIs. I am testing on HTC One X (OS v 4.1.1)

Below is the android code that I applied to get location updates using new APIs:

Step1:

mLocationClient = new LocationClient(this, this, this);

Step2:

// Create the LocationRequest object
mLocationRequest = LocationRequest.create();
// Use high accuracy
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
// Set the update interval to 5 seconds
mLocationRequest.setInterval(UPDATE_INTERVAL);
// Set the fastest update interval to 1 second
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);

Step3: inside onStart() method - below line is added:

// Connect the client.
mLocationClient.connect();

Step4: inside onConnected() method - below line is added:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Step5: inside onLocationChanged() method - listening for location updates. This method is not called when testing insides. This method is getting called only when GPS signal is found.

double lat = location.getLatitude();
double lng = location.getLongitude();

Finally added below permissions in Android Manifest:

 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Based on your snippets your code looks fine to me for receiving indoor locations.

Try doing a dump while your app is requesting locations and you are indoors (expecting to receive locations but not): adb shell dumpsys activity service com.google.android.location.internal.GoogleLocationManagerService

Can you post the output here?

Can you double check that Settings->WiFi is enabled, and that Settings->Location access->Wi-Fi & mobile network location is enabled (both are required for indoor location).

Does your phone have a sim card? This would allow cell tower derived locations when wifi isn't available.

Finally you said that Google Maps gives you a location indoors in the same building. What is the approximate size of the accuracy circle (i.e. is it closer to 20 meters or 100 meters)?
