Having trouble creating google maps in a fragment

Question

I have looked through about 10 stackoverflow pages on this topic and none of the solutions are helping me. I have copied the code from the first answer in this post, but I am still getting a lot of errors. What I want is to create the map in a class called MapFragment, and then display it in a tab of an app.

As of now here is my code: Java:

public class MapFragment extends Fragment {
    private static final String ARG_SECTION_NUMBER = "section_number";
    private final LatLng HAMBURG = new LatLng(53.558, 9.927);   //Error: cannot resolve symbol 'LatLng'
    private final LatLng KIEL = new LatLng(53.551, 9.993);      //Error: cannot resolve symbol'LatLng'
    private GoogleMap map;                    //Error: cannot resolve symbol GoogleMap

    public MapFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        View rootView = inflater.inflate(R.layout.fragment_map, container, false);

        map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();      //Error:cannot resolve symbol 'SupportMapFragment'

        Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
                .title("Hamburg"));                          //Error:cannot resolve symbol 'Marker' or 'MarkerOptions' or method 'addMarker'
        Marker kiel = map.addMarker(new MarkerOptions()      //Error:cannot resolve symbol 'Marker' or 'MarkerOptions' or method 'addMarker'
                .position(KIEL)
                .title("Kiel")
                .snippet("Kiel is cool")
                .icon(BitmapDescriptorFactory
                .fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to hamburg with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));    //Error:cannot resolve symbol 'CameraUpdateFactory' or method 'moveCamera'

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);//Error:cannot resolve symbol 'CameraUpdateFactory' or method 'animateCamera'

        //...

        return rootView;
    }
}

    </application>

</manifest>

my dependencies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.google.android.gms:play-services:7.5.0'
}

I do not understand what is going on. Is there some import I am missing class I need to cut and paste to make this work? On a diferent tutorial they had me import this

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

but on both lines I get an error cannot resolve symbol 'android'.

I am currently using android studio. The API key is entered in my actual compute I just left it out from the stack overflow post.

Answer 1

Below steps for taking care when we are working with Google map.

Make sure you have added Google Play Services Library as Library project.

If you are sure for above step and still problem is not resolved than please update your Google Play Service Library by SDK Manager.

If you have updated library and still problem is not resolved than please do Clean and ReBuild project.

If you have performed above step and still problem is not resolved than please restart your Eclipse, sometime magically it works.

Hope it will help you.

You need to add more detail in your question. - Do you use Android Studio or Eclipse? - Did you add your key of google map into your manifest or not. - If use Android Studio did you add dependency of google play service into your gradle build file? May be it because you forgot to add dependency so the compiler cannot find your class
