Answer 1

The problem is that the code you tried does work, probably just not as well as you wished. For example, the accuracy such a method provides on Samsung Galaxy S3 is 2000m, meaning the actual position is anywhere within a circle of 2 kilometers radius. Additional it would probably take quite a large change in location before your app would be informed of a location change since the margin of error is so big.

A GPS or LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY (if Google Play Services is used) is required to get a reasonably good location. This does require android.permission.ACCESS_FINE_LOCATION, however unless you only require km level accuracy, otherwise this permission is a must.

Finally note that using Google Play Services with LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY I can get location data as accurate as 10m without turning on GPS, so this should still satisfy your requirement.

Below is a complete example:

AndroidManifest.xml

MainActivity.java

import android.app.Activity;
import android.location.Location;
import android.os.Bundle;
import android.widget.TextView;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
import com.google.android.gms.location.FusedLocationProviderApi;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationServices;

public class MainActivity extends Activity implements
        com.google.android.gms.location.LocationListener, ConnectionCallbacks,
        OnConnectionFailedListener {
    private final FusedLocationProviderApi fusedLocationProviderApi = LocationServices.FusedLocationApi;
    private GoogleApiClient mGoogleAPIClient;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mGoogleAPIClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API).addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this).build();
    }

    @Override
    protected void onResume() {
        super.onResume();

        mGoogleAPIClient.connect();
    }

    @Override
    protected void onPause() {
        super.onPause();

        if (mGoogleAPIClient != null) {
        mGoogleAPIClient.disconnect();
        }
    }

    @Override
    public void onConnected(Bundle arg0) {
        final LocationRequest locationRequest = LocationRequest.create();
        locationRequest
                .setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
        locationRequest.setInterval(30 * 1000);
        locationRequest.setFastestInterval(5 * 1000);
        fusedLocationProviderApi.requestLocationUpdates(mGoogleAPIClient,
                locationRequest, this);
    }

    @Override
    public void onConnectionSuspended(int arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onConnectionFailed(ConnectionResult arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onLocationChanged(Location location) {
        // the location is no more than 10 min old, and with reasonable
        // accurarcy (50m), done
        if (System.currentTimeMillis() < location.getTime() + 10 * 60 * 1000
                && location.getAccuracy() < 50) {
            mGoogleAPIClient.disconnect();
            mGoogleAPIClient = null;
            ((TextView) findViewById(R.id.test)).setText(location.toString());
        }
    }
}
