Android gets the wrong location of the emulator

I made an app that stores the position of the device (latitude and longitude) and to actually test it I tried to change the GPS location of the emulator from the default location in Mountain View to a random location in Rome. I followed this thread to do it. The problem is that my app still stores the default location rather than the new location I set.
This is how I access the location:
public class GPSTracker extends Service implements LocationListener {
private final Context mContext;
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 m
private static final long MIN_TIME_BW_UPDATES = 1000 * 60; // 1 minute
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context;
getLocation();
}
public Location getLocation() {
Location location = null;
try {
locationManager = (LocationManager) mContext.getSystemService(LOCATION_SERVICE);
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
throw new Exception("GPS must be turned on!");
}
else {
if (isNetworkEnabled) {
if (ActivityCompat.checkSelfPermission((Activity)mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission((Activity)mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
throw new Exception("Permission needed for location!");
}
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("Network", "Network");
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
}
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
}
}
}
}
}
catch (Exception e) {
e.printStackTrace();
}
return location;
}
#Override
public IBinder onBind(Intent arg0) {
return null;
}
public void showSettingsAlert() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);
alertDialog.setTitle("GPS turned off");
alertDialog.setMessage("Turn on the GPS!");
alertDialog.setPositiveButton("Impostazioni", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
mContext.startActivity(intent);
}
});
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
alertDialog.show();
}
public void stopUsingGPS() {
if (locationManager != null) {
locationManager.removeUpdates(GPSTracker.this);
}
}
}
This is how I use those methods and actually store the location on the Database:
public class HomeActivity extends AppCompatActivity {
private GPSTracker gpsTracker;
String ServerURL = "http://10.0.2.2/api/insert.php";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
final Button bottone1 = findViewById(R.id.bottone1);
bottone1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(HomeActivity.this, MainActivity.class);
gpsTracker = new GPSTracker(HomeActivity.this);
Location location = gpsTracker.getLocation();
if (location != null) {
double latitude = location.getLatitude();
double longitude = location.getLongitude();
DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
Date datenotformatted = new Date(location.getTime());
String date = format.format(datenotformatted);
String lat = String.valueOf(latitude);
String lon = String.valueOf(longitude);
startActivity(intent);
insertData(lat, lon, date);
}
else {
gpsTracker.showSettingsAlert();
}
}
});
}
private void insertData(final String latitude, final String longitude, final String date){
class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
String first = latitude;
String second = longitude;
String third = date;
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(ServerURL);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("latitudine", first));
nameValuePairs.add(new BasicNameValuePair("longitudine", second));
nameValuePairs.add(new BasicNameValuePair("data", third));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
if (httpEntity == null) {
Toast.makeText(HomeActivity.this, "Errore.", Toast.LENGTH_LONG).show();
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return "Success.";
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
}
}
SendPostReqAsyncTask sendPostReqAsyncTask = new SendPostReqAsyncTask();
sendPostReqAsyncTask.execute(latitude, longitude, date);
}
The location the app gets everytime:
The actual location of the emulator I set:

You can generate an api key along with Google maps & Google places api in your developers console (Click on the circled link and Enable the api)
You can call the api like below with your AutoCompleteView onclick listener or any other listener of your wish
private int PLACE_AUTOCOMPLETE_REQUEST_CODE = 1;// declare this globally
//Call this on your listener method
Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
.build(getActivity());
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
This will open the Google place search screen and you can get the result like below
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == getActivity().RESULT_OK) {
Place place = PlaceAutocomplete.getPlace(getActivity(), data);
mSearchPlace = place;
mSearchText.setText(String.valueOf(place.getName()));
// You will get Lat,Long values here where you can use it to move your map or reverse geo code it.
LatLng latLng = new LatLng(place.getLatLng().latitude, place.getLatLng().longitude);
mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 12));
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(getActivity(), data);
} else if (resultCode == getActivity().RESULT_CANCELED) {
// The user canceled the operation.
}
}
}
Hope this helps.

How to get user details after successful Login through Facebook

I tried this: when isSessionValid getDetails directly else facebook.authorize and then getDetails in onActivityResult
public class MainActivity extends Activity {
Facebook facebook = new Facebook("xxxxxxxxxxxxxxxx");
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
private SharedPreferences mPrefs;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this, new String[] {}, new DialogListener() {
#Override
public void onComplete(Bundle values) {
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", facebook.getAccessToken());
editor.putLong("access_expires",
facebook.getAccessExpires());
editor.commit();
}
#Override
public void onFacebookError(FacebookError error) {
}
#Override
public void onError(DialogError e) {
}
#Override
public void onCancel() {
}
});
}else{
try {
JSONObject json = Util.parseJson(facebook.request("me"));
String facebookID = json.getString("id");
String firstName = json.getString("first_name");
String lastName = json.getString("last_name");
String email = json.getString("email");
String gender = json.getString("gender");
} catch (Exception e) {
}
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
facebook.authorizeCallback(requestCode, resultCode, data);
try {
JSONObject json = Util.parseJson(facebook.request("me"));
String facebookID = json.getString("id");
String firstName = json.getString("first_name");
String lastName = json.getString("last_name");
String email = json.getString("email");
String gender = json.getString("gender");
} catch (Exception e) {
}
}
public void onResume() {
super.onResume();
facebook.extendAccessTokenIfNeeded(this, null);
}
}
This works fine when I have facebook app installed on my system. But If not installed i get a Web View to enter facebook credentials and in logcat shows login-success, but none of the getDetails block is called.

Here in initFacebook() function through you can login and perform you functionality, here i am fetching user's friends information.
private void initFacebook()
{
try
{
if (APP_ID == null)
{
Util.showAlert(this,"Warning","Facebook Applicaton ID must be "+ "specified before running this example: see Example.java");
}
mFacebook = new Facebook();
mAsyncRunner = new AsyncFacebookRunner(mFacebook);
mFacebook.authorize(FacebookList.this, APP_ID, new String[] {"email", "read_stream", "user_hometown", "user_location","friends_about_me", "friends_hometown", "friends_location","user_relationships", "friends_relationship_details","friends_birthday", "friends_education_history","friends_website" }, new DialogListener()
{
public void onComplete(Bundle values)
{
getHTTPConnection();
}
public void onFacebookError(FacebookError error)
{
Log.i("public void onFacebookError(FacebookError error)....","....");
}
public void onError(DialogError e)
{
Log.i("public void onError(DialogError e)....", "....");
CustomConfirmOkDialog dialog = new CustomConfirmOkDialog(FacebookList.this, R.style.CustomDialogTheme, Utils.FACEBOOK_CONNECTION_ERROR);
dialog.show();
}
public void onCancel()
{
Log.i("public void onCancel()....", "....");
}
});
SessionStore.restore(mFacebook, this);
SessionEvents.addAuthListener(new SampleAuthListener());
SessionEvents.addLogoutListener(new SampleLogoutListener());
}
catch (Exception e)
{
e.printStackTrace();
}
}
Here in getHTTPConnection(), proceeding for connection and sending fields, that we require about user's friends as here we can see that passing fields are fields=id,first_name,last_name,location,picture of friends. here you can change this fields according to application's requirements.
private void getHTTPConnection()
{
try
{
mAccessToken = mFacebook.getAccessToken();
HttpClient httpclient = new DefaultHttpClient();
String result = null;
HttpGet httpget = new HttpGet("https://graph.facebook.com/me/friends?access_token="+ mAccessToken + "&fields=id,first_name,last_name,location,picture");
HttpResponse response;
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null)
{
result = EntityUtils.toString(entity);
parseJSON(result);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
Now after successfully connecting with facebook , we are getting JSON data and further to parse it .
private void parseJSON(String data1) throws Exception,NullPointerException, JSONException
{
try
{
JSONObject jObj = new JSONObject(data1);
JSONArray jObjArr = jObj.optJSONArray("data");
int lon = jObjArr.length();
for (int i = 0; i < lon; i++)
{
JSONObject tmp = jObjArr.optJSONObject(i);
String temp_image = tmp.getString("picture"); String temp_fname = tmp.getString("first_name");
String temp_lname = tmp.getString("last_name");
String temp_loc = null;
JSONObject loc = tmp.getJSONObject("location");
temp_loc = loc.getString("name");
}
}
catch (Exception e)
{
Log.i("Exception1 is Here>> ", e.toString());
e.printStackTrace();
}
}
It is assumed that you have already added a facebook jar in to your application and for proceeding this code you can call initFacebook() in to onCreate() of your activity
