MapFragment in Fragment, alternatives?

Question

I need your help... I work on it until 3 days. My app is working with fragments. One of these fragments has to display a map from the Google Maps V2 api for Android.

Answer 1

Use SupportMapFragment to overcome this error:

In fragment layout

<fragment
android:id="@+id/googleMap"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />

In Your Fragment onCreateView

SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);

        if (mapFragment != null) {
            mapFragment.getMapAsync(this);
        }

Since your layout is in the Fragment's layout, therefore the SupportMapFragment is the child layout of your fragment. Hence use getChildFragmentManager() which is Fragment's FragmentManager

Answer 2

Use MapView instead of MapFragment in your Fragment's layout. Remember to call MapView's lifecycle methods:

• onCreate(Bundle)
• onResume()
• onPause()
• onDestroy()
• onSaveInstanceState(Bundle)
• onLowMemory()

as described here.

Btw. you shouldn't be using MapFragment, only SupportMapFragment and support library.

Edit:

If you switch to support library, you can use code from comment #1 here: http://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1
