RuntimeException: Error inflating class fragment

Question

I am getting a runtimeException with the following code, does anyone know why?

public class FragsApplicationActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

SuggestionFrags class

public class SuggestionFrags extends Fragment{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        return super.onCreateView(inflater, container, savedInstanceState);
    }

}

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <fragment
        android:id="@+id/fragment1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        class="com.samplefragsapplication.SuggestionFrags" />

</LinearLayout>

I am getting this exception:

Could you post the entire stacktrace from LogCat instead of just one line? — kaspermoerch, Nov 23 '11 at 12:40

If you are going to use Fragments you need to extend FragmentActivity not Activity.

To fix this issue you have to extends from FragmentActivity instead of Activity in the FragsApplicationActivity.

The proper form will be

<fragment
    android:id="@+id/fragment1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:name="com.samplefragsapplication.SuggestionFrags" />

UPD: judging by the logcat output, you don't have fragments available. If you're running a pre-Honeycomb android (but >= 1.6), you can use the compatibility library. Fragments were introduced in 3.0.

I am using compatibility library. I set my minSdkVersion="7". But that still doesn't resolve the issue. – IgorGanapolsky May 10 '12 at 02:22

The exception android.view.InflateException: Binary XML file line: #... Error inflating class fragment might happen if you manipulate with getActivity() inside your fragment before onActivityCreated() get called. In such case you receive a wrong activity reference and can't rely on that.

For instance the next pattern is wrong:

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

    Button button = getActivity().findViewById(R.id...);
    button.setOnClickListener(...); - another problem: button is null

    return view;
}

I just had the same issue, and what I found was that in my main.xml I was incorrectly referencing the fragment class.

Instead of:

<fragment android:id="@+id/frag_capt"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.company.test.applicationname.fragmentname" />

try:

<fragment android:id="@+id/frag_capt"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.company.test.DetailFrag" />

This fixed the issue for me. Good luck.

Try this

<fragment
        android:id="@+id/fragment1"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true" />

Make sure android:name="className" is the first parameter in the list

ex

<fragment
    android:name="com.name.first"
    android:id="@+id/"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />

I had the same issue, to summarise:

Extend from FragmentActivity

Follow this structure in your layout

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