android - Having an issue with GoogleMap v2 crashing app on orientation change

Question

I've been dealing with this problem for a while now. I used this question as a reference: Using ActionBarSherlock With the New SupportMapFragment

I'm currently using ActionBarSherlock and I'm using Vipul Shah's rather simple implementation of a map. It works brilliantly, does exactly what I need it to. However, on Orientation change, the entire app crashes. Here is my log:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.meetball_1/com.meetball_1.HomeActivity}: android.view.InflateException: Binary XML file line #17: Error inflating class fragment

I realize that for whatever reason a view is not being created and that the error comes from the app failing to inflate my class fragment. How do I fix this without making things too complicated because I feel that implementing the map was simple so should be my solution. here is my xml snippet:

<fragment android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="230dp"
    android:layout_weight="1"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_gravity="center_horizontal|top" />

Here is my relevant code snippet:

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

 SupportMapFragment fragment = SupportMapFragment.newInstance();
        getSupportFragmentManager().beginTransaction()
                .add(R.id.map, fragment).commit();
}

Thank you all in advance!

I've tried everything at this point. Is this a bug with Googlemap? How do I fix it?

Answer 1

I had the same problem and to solve it, I had to use FrameLayout instead of fragment:

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

And then:

SupportMapFragment mMapFragment = (SupportMapFragment) getActivity()
            .getSupportFragmentManager().findFragmentById(R.id.mapview);

    if (mMapFragment == null) {
        mMapFragment = SupportMapFragment.newInstance();
        fm.beginTransaction().replace(R.id.mapview, mMapFragment).commit();
    }
