Java – in Google Maps V2… Fragment Getmap() returns null

I can't get the map! All I can get is null

Here is the code

public class MainActivity extends FragmentActivity {

     @Override
     protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        SupportMapFragment fragment = new SupportMapFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content,fragment).commit();


       GoogleMap map;
        map = fragment.getMap();
             //here i cant access this snippet because map = null 
        if(map!=null){
        UiSettings mm = map.getUiSettings();
        map.setMyLocationEnabled(true);
          } }
           }

Here is XML:

 android:layout_height="match_parent"

 <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.MapFragment"/>

<TextView

    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@string/hello_world" />

  </RelativeLayout>

I try to solve it like this solution Google Maps Android API V2 throws Google playservicesnotavailableexception, out of date, supportmapfragment getMap() returns null .. But still no job

to update:

My map is working now Here is the working version of the edit

public class MainActivity extends FragmentActivity {
 private GoogleMap myMap;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

          android.support.v4.app.FragmentManager myFragmentManager = getSupportFragmentManager();
          SupportMapFragment mySupportMapFragment 
           = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);


             myMap = mySupportMapFragment.getMap();
             if(myMap!=null)
            myMap.setMyLocationEnabled(true);


        }

Solution

You are creating a dynamic fragment through a fragmenttransaction When commit () is called, the fragment has not yet been added to the screen because the fragmenttransaction is only scheduled to occur - it has not yet occurred Therefore, supportmapfragment has not been called by oncreateview(), so there is no Google map

Switch to a static fragment (the < fragment > tag in the layout), or delay using Google map until the processing is complete
