Android map Version 2 with supporte library

Question

I’m using the Android maps v2 api.

I have in my Activity the following statement

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp" android:layout_weight="1"/>

And the following code to retrieve the Map:

 GoogleMap mMap = ((MapFragment) getSupportFragmentManager().findFragmentById(
                R.id.map)).getMap();

This code shows the following error:

 Error:(150, 79) java: inconvertible types
  required: com.google.android.gms.maps.MapFragment
  found:    android.support.v4.app.Fragment

How do I use version 2 of the android maps when using the compatibility API?

Answer 1

To use the compatibility api you need to make two changes to your code.

In xml, add the compatibility api map class:

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp" android:layout_weight="1"
        class="com.google.android.gms.maps.SupportMapFragment"/>

And on your Activity:

    GoogleMap mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(
                R.id.map)).getMap();

This will correct your mistake.
