I am trying to show my current location on google maps but it displays black screen in the map fragment.

}
}
i included all the libraries and generated the API key
output is shown below
no error message is logged. what could possibly go wrong in displaying the map ?
Note : same code is working on another application with different API key ofcourse and map is displayed correctly.
IMPORTANT NOTE:The app was already published on google play store before adding the Maps SDK API,so is there any modifications that I should do considering that or its irrelative?
Go to console.google.com
And generate a new API key with package name(com.package.app) same as in your mobile app and SHA1.
Get the new API key, replace in the code. Uninstall the app and re-run.
Okey , so i am not using FragmentActivity, and this may not directly tell the solution.
But this code definitely works and shows map using android.support.v4.app.Fragment.
import android.support.v4.app.Fragment;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.OnMapReadyCallback;
public class OrderMapFrag extends Fragment implements OnMapReadyCallback{
private GoogleMap mGoogleMap;
private MapView mMapView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_order_map, container, false);
........
........
mMapView.onCreate(savedInstanceState);
mMapView.onResume();
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
mMapView.getMapAsync(this);
return view;
}
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
//setting initial elements in map if required after this , as map got initialized properly
}
}
But I am not using exact same elements and permissions you use in Manifest. For me these are the used ones.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

I am trying over a week to setup my Google Map v2. but its not working for me.I tried answers from questions related to it but no use.i couldn't track the exact problem.please help.
Here is my xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<fragment
android:id="#+id/map"

In my map.class I have

if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
}
My API key is correct and I imported google play services library as per the directions.In my manifest file

This is my error log
And in console I got can not find googleplayserviceslib.apk error too.

you need to extend FragmentActivity/AppCompatActivity if you are using SupportMapFragment.
public class Map extends FragmentActivity/AppCompatActivity {
And
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
googleMap = mySupportMapFragment.getMap();
You can check Android Map V2
Try this
googleMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
Try this...

I have a navigation drawer with fragments for each page. And in one of my fragments i want to display a mapview. But not in full screen, i want it to be like the top half of screen and below that i will give some contact information for a specific coordinate.
I tried too many tutorial but i couldn't get this working.
The Page XML which Map is supposed to be displayed

compile 'com.android.support:support-v4:20.0.0'
compile 'com.google.android.gms:play-services:5.2.08'

However my final result is this. I am sure that Google Play Services is up-to date on the phone. So do you have any suggestions?
Change your gradle file to

Basically I am trying to make an app which displays a Google Map.Here is my code.

</LinearLayout>
MainActivity class...
import com.google.android.maps.MapActivity;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
When I run it,I get the following message
06-22 15:54:03.622: E/AndroidRuntime(26187): FATAL EXCEPTION: main

you forgot to add uses-library in your manifest file,in this case
<application>
...
<uses-library android:name="com.google.android.maps"
android:required="true" />
...

I think you are using MAP API version 1 which is deprecated.
Why Cant you use API 2 either Fragment or support-fragment (https://developers.google.com/maps/documentation/android/start)
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
Manifest file
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyC8qEhdHVd3ZtxCR0549UqwnM72h0jgoMY" />
Basically I had to use the use the SupportMapFragment like this to make it work for android 2.3 .Also had to create a new API key..
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
And an sample of my java code is this.
public class EmergencyMap extends FragmentActivity {
static final LatLng ASTYNOMIA = new LatLng(39.620530, 22.401728);
static final LatLng PYROSVESTIKH = new LatLng(39.632652, 22.398704);

private GoogleMap map;

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_emergency_map);
map = ((SupportMapFragment)getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
map.addMarker(new MarkerOptions().position(ASTYNOMIA).title("ΑΣΤΥΝΟΜΙΑ"));
map.moveCamera(CameraUpdateFactory.newLatLngZoom(ASTYNOMIA,15));
map.animateCamera(CameraUpdateFactory.zoomTo(20),2000,null);

But in MainAntivity.java it gives me an error I'm not sure how to solve:
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
I get map cannot be resolved or is not a field but it reffers to: d(R.id.map)
Any ideas why map in R.id.map is failing??
EDIT :

Have you implemented the Fragment in XML file? Refer this blog
// try this way,hope this will help you...
1.Replace this code
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
With this
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
2.Add this permission in AndroidManifest file
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Note : if you are using latest google-play-services jar for map then you have to also define below meta-data in your AndroidManifest file
<meta-data android:name="com.google.android.gms.version"
android:value="4030500" />
Try using below code
xml
<fragment
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
class="com.google.android.gms.maps.SupportMapFragment" />
java
public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment supportMapFragment = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
// Getting a reference to the map
googleMap = supportMapFragment.getMap();
}
}
Also your app should extend FragmentActivity.
Just add class="com.google.android.gms.maps.MapFragment" activity_maps.xml
I tried everything, I researched and I can't get run my application. Each time I Run my application on my device get the message: "Sorry, Map has been has been interrupted". I done all the steps from this page https://developers.google.com/maps/documentation/android/start?hl=pl, and follow many tutorial and nothing. I hope you can save me.

Please Help me!!!!
try this :
class="com.google.android.gms.maps.SupportMapFragment"
on your activity :
SupportMapFragment mapfragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.showmap);
I think your problem in
android:name="com.google.android.gms.maps.MapFragment"
try instead of this, in the way:
class="com.google.android.gms.maps.MapFragment"
P.S. sometimes problem with maps is in not available Google Play Service on device.
(GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS)
must be true.
