Google地图未显示在Fragment子类

Question

我创建了一个地图，它在另一个活动的片段中显示。在我的应用程序中只有一个Activity类。我需要在Fragment中显示它。

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


public class Atm extends Fragment {
private SupportMapFragment mSupportMapFragment;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.atm_main,
            container, false);

    mSupportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.mapAtm);
    if (mSupportMapFragment == null) {
        FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        mSupportMapFragment = SupportMapFragment.newInstance();
        fragmentTransaction.replace(R.id.mapAtm, mSupportMapFragment).commit();
    }

    if (mSupportMapFragment != null) {
        mSupportMapFragment.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                if (googleMap != null) {

                    googleMap.getUiSettings().setAllGesturesEnabled(true);

                    LatLng marker_latlng = new LatLng(150, -150);

                    CameraPosition cameraPosition = new CameraPosition.Builder().target(marker_latlng).zoom(15.0f).build();
                    CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition);
                    googleMap.moveCamera(cameraUpdate);

                }

            }
        });


    }
    return view;
}
}

他们在Emulator中没有错误。但是在Mobile中安装后，应用程序将在点击Atm Map时终止
