Caused by: android.view.InflateException: Binary XML file line #11: Error inflating class fragment

Question

I'm trying to build an app with fragments, which are at the beginner level and I have no direct solid knowledge or experience in the subject.

I want WebViewFragment be visible when the app starts, before later adding a ListView side.

As it stands now, the app crashes as soon as I start it on the phone. I have paste the errorlog below.

Trying to instantiate a class com.raj.fragment.WebViewFragment that is not a Fragment

The log says it all

Change to

public class WebViewFragment extends Fragment {

Because you have

<fragment android:name="com.raj.fragment.WebViewFragment" // is a fragment

Your Fragment is hosted by the MainActivity.

Also you can have either class="com.raj.fragment.WebViewFragment" or android:name="com.raj.fragment.WebViewFragment". No need to have both.

Also add @Override annotation

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

Edit:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);// missing  
}

Thank You!But when I add the @Override, Eclipse giving me "The method onCreateView(LayoutInflater, ViewGroup, Bundle) of type WebViewFragment must override or implement a supertype method" :/

Raghunandan Over a year ago

@user2734182 its just a annotation to indicate a that its a overriden method. It should work without it though

user2734182 Over a year ago

"Caused by: java.lang.ClassCastException: com.raj.fragment.MainActivity cannot be cast to android.app.Activity"

Raghunandan Over a year ago

@user2734182 post your updated code both activity code and the fragment code along with import statements

user2734182 Over a year ago

Now it works =) Or yes, the app starts but is blank / white: S

The WebViewFragment should not be a FragmentActivity. Since it is a fragment it should inherit Fragment.

public class WebViewFragment extends Fragment
