I'm developing a taxi application. The only problem is my marker doesn't update it's location screamingly on mapview. After some debugging I noticed that the listener named onLocationChanged is never called!!!
The idea is to view a marker on mapview to view driver's location and track is own location while driver. But, the problem is his marker never changes!.
Here is my code:

What's the problem with my code?
I am using this piece of code to get user coordinates and then send the coordinates to the geocoding API. my code works fine in the emulator since I am sending the coordinates through emulator control but when it comes to a real device I am not getting any response.
I have given the necessary permissions in the manifest. I have tried all the necessary ways but I got no positive result. please help me in this regard I need to submit my project within few days.

I am using a map and location listener. I am calling the location listener when the map is ready and showing marker's on map after getting the location from location listener , all this in setMap() method.
When I am getting the location I see some numbers on snackbar, I dont know from where it is coming, nowhere I am showing it. I am showing snackbar's to show the internet and gps alert. But this is coming from nowhere.
Looks like this:

As I did debug I found that I get this in onLocationChanged method when the setMap() method is called, before or after the method is called.
Which number is this?? Please help thank you..
Replace this in your code:
getString(R.string.locationAlert);
With this.
getResources().getString(R.string.locationAlert);
The issue is getString(R.string.locationAlert); this code returns the R file integer assigned space.
I have a map on which I want to show user's current location and I am calling an api after getting user's location to get the nearby merchants.
I am getting the user's current location, also all the merchants are getting plot by markers on map.
But I have called the setMap method in the onLocationChanged() method of LocationListener. This method get's called continuously.
I want to get the location once and show on the marker, again when next time user comes to this fragment then only I want to get updated location.
But now it's going in a loop continuously that onLocation method get's called and so accessMerchants is getting called.
To stop this I tried to remove updates from location manager, also I tried to set a boolean variable if it first time goes in onLocationChanged() method, it will be false but again it is also going in a loop.
Remove updates also not working, if remove updates is worked, then onLocationChanged method should not get called again right?

What's going wrong?? Please help.. Where should I call removeUpdates?? thank you..
You register for updates from 2 providers, did you deregister from both?
Also, to make the boolean flag work you need to make a change- set it to true at the end of the function, and change the if to if(!receivedLocation) That will make it run only once. As it is, it will never run.
I am a learner in android. I am trying to get weather on current location. There is a "Refresh" button in my app to update the UI with latest weather details. When the app loads, it shows weather of 0.0, 0.0 latitude and longitude. When I click on "Refresh" button, it shows the weather of my current location. How can I get the weather of my current location when the app loads? I have used Google Play Services to get the current location. Below is my code.
MainActivity.java
public class MainActivity extends ActionBarActivity implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
public String apiKey;
public double latitude;
public double longitude;
public String forecastUrl;
public static final String TAG = MainActivity.class.getSimpleName();

mRefreshImageView.setOnClickListener(new View.OnClickListener() {
#Override

getForecast();
}
});
getForecast();
}

mGoogleApiClient = new GoogleApiClient.Builder(this)

.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
protected void onResume() {
super.onResume();
mGoogleApiClient.connect();
}
protected void onStop() {
super.onStop();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
}
private void getForecast() {
if (isNetworkAvailable()) {
forecastUrl = “http://www.forecastUrlGoesHere.com/" + apiKey + “/“ + latitude + "," + longitude;
toggleRefresh();
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url(forecastUrl).build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Request request, IOException e) {
runOnUiThread(new Runnable() {
#Override
public void run() {
toggleRefresh();
}
});
}
#Override
public void onResponse(Response response) throws IOException {
runOnUiThread(new Runnable() {
#Override

}
});
try {
String jsonData = response.body().string();
if (response.isSuccessful()) {
runOnUiThread(new Runnable() {
#Override
public void run() {
updateView(); //updates the screen ui
}
});
} else {
alertUserAboutError();
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
}
}
});
} else {
Toast.makeText(this, getString(R.string.network_error_message), Toast.LENGTH_LONG).show();
}
}

} else {
Log.i(TAG, "Connection failed, ERROR: " + connectionResult.getErrorCode());

Well there are a few ways to get the expected result. Let me write the steps for one of them:
a) Use a ProgressDialog and start it in onCreate
b) Move the getForecast() from onCreate
c) In the onConnected method, once the lat and long are available, check if the ProgressDialog is still visible. If yes, dismiss this dialog and call getForecast
ProgressDialog link
http://developer.android.com/reference/android/app/ProgressDialog.html
In your onConnected callback, call getForecast();:
#Override
public void onConnected(Bundle bundle) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation != null) {
latitude = mLastLocation.getLatitude();
longitude = mLastLocation.getLongitude();
Toast.makeText(this, latitude + " " + longitude, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, getString(R.string.no_location_detected), Toast.LENGTH_LONG).show();
}
getForecast();
}
