onLocationChanged rief nie

Question

Ich weiß nicht, warum meine Karte nicht onLocationChanged aufrufen, wenn ich meine Taste drücke. Das sind meine Berechtigungen:

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

Dies ist meine Klasse:

public class NuevaCarreraFragment erweitert Fragment implementiert OnMapReadyCallback, Location, View.OnClickListener {

private View view;

public static NuevaCarreraFragment newInstance() { 
    Bundle args = new Bundle(); 
    NuevaCarreraFragment fragment = new NuevaCarreraFragment(); 
    fragment.setArguments(args); 
    return fragment; 
}

Die Karte wird richtig angezeigt, aber es bekomme meinen Standort nicht :(. Irgendwelche Idee?

UPDATE

Endlich konnte ich lösen, Problem bei der Implementierung von Google API Client und Fused Location Api.

Answer 1

1. Hat die App eine Berechtigung? Hast du den nicht gewährten Fall behandelt?
2. Und diese Provider die App-Anfragen sind aktiviert?
3. Haben Sie die App debuggen und erreichen Sie die Zeile locationManager.requestLocationUpdates?

Scheint, wie die App nicht aufgrund fehlender von 1 und 2
