In Version 2 Map view does not show map

Question

Map Activity doesn't showing map, it's appear as just white screen with zoom control buttons. Manifest File like this :

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.demomap"     android:versionCode="1"     android:versionName="1.0" >     <uses-sdk         android:minSdkVersion="8"         android:targetSdkVersion="17" />    <permission         android:name="com.example.demomap.permission.MAPS_RECEIVE"         android:protectionLevel="signature" />     <uses-permission android:name="com.example.demomap.permission.MAPS_RECEIVE" />     <uses-permission android:name="android.permission.INTERNET" />     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />     <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />     <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />         <application         android:allowBackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/AppTheme" >         <activity             android:name="com.example.demomap.MainActivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.MAIN" />                  <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>         </activity>          <meta-data             android:name="com.google.android.maps.v2.API_KEY"             android:value="AIzaSyCTQZOcXFS3RpNSVe79HHN1xojat-2MbT4" />     </application>     <uses-feature         android:glEsVersion="0x00020000"         android:required="true" /> </manifest> 

My XmL File Like these:

<?xml version="1.0" encoding="utf-8"?> <fragment     xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent"     class="com.google.android.gms.maps.SupportMapFragment" /> 

Log Cat Error:

05-15 17:15:16.255: E/Google Maps Android API(26201): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors). 

Please Help me.

Answer 1

Maybe the key isn't correct. You can try the following thing:

• Be sure you Enter your right Package name like this
• Test on a real device which updated latest google play. Or use emulator with this guide

• Active google map api v2 for android at google console site

Answer 2

I got this problem using MapView

fragment_map.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">  <com.google.android.gms.maps.MapView     android:id="@+id/mapview"     android:layout_width="fill_parent"     android:layout_height="fill_parent"/> 

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {     String message = getArguments().getString(EXTRA_MESSAGE);     v = inflater.inflate(R.layout.map_f, container, false);     vh = new ViewHolder();     assetHandler = new AssetHandler(getActivity());     vh.mapView=assetHandler.mapViewHandler.set(v,R.id.mapview);     vh.mapView.onCreate(savedInstanceState);      vh.mapView.getMapAsync(new OnMapReadyCallback() {         @Override         public void onMapReady(GoogleMap googleMap) {             googleMap.getUiSettings().setMyLocationButtonEnabled(true);             googleMap.setMyLocationEnabled(true);             // Needs to call MapsInitializer before doing any CameraUpdateFactory calls             try {                 MapsInitializer.initialize(getActivity());             } catch (Exception e) {                 e.printStackTrace();             }         }     });     return v; }   @Override public void onResume() {     super.onResume();     vh.mapView.onResume();   }  @Override public void onPause() {     vh.mapView.onPause();     super.onPause(); }  @Override public void onDestroy() {     vh.mapView.onDestroy();     super.onDestroy(); }  @Override public void onLowMemory() {     super.onLowMemory();     vh.mapView.onLowMemory(); } 

I noticed if the LifeCycle methods are not implemented, you will not be able to see the map as well. hope this is hopeful for some.
