Unable to start activity ComponentInfo{Activity}: android.view.InflateException: Binary XML file line Error inflating class fragment

I am getting the following exception, when I try to start a fragment inside a activity. It seems like this is a common problem, I have all the permissions necessary as suggested in the answers. The trace is not very helpful.

Process: com.eazysystems.transdoc, PID: 11129

And also, the exception happens at the
setContentView(R.layout.activity_view_record);
in this Activity class. I tried to make the application simple as possible but it get the same exception

public class ViewRecordActivity extends AppCompatActivity {

private static String RECORD_ID = "RECORD_ID";

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

/*Bundle extras = getIntent().getExtras();
Integer recordId = extras.getInt(RECORD_ID);*/

ViewRecordFragment viewRecordFragment = ViewRecordFragment.newInstance(1);
//viewRecordFragment.setArguments(getIntent().getExtras());

FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager
.beginTransaction()
.replace(R.id.view_record_fragment, viewRecordFragment
).commit();
}


public static class ViewRecordFragment extends Fragment {

private static String RECORD_ID = "RECORD_ID";

public ViewRecordFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
/*gridview = (GridView) getActivity().findViewById(R.id.image_grid_view);*/

//Integer recordId = getArguments().getInt(RECORD_ID);
//loadImageResourcesAsync(recordId);

return inflater.inflate(R.layout.fragment_view_record, container, false);
}

public static ViewRecordFragment newInstance(Integer recordId) {
ViewRecordFragment fragment = new ViewRecordFragment();
//fragment.loadImageResourcesAsync(recordId);
/*Bundle bundle = new Bundle();
bundle.putInt(RECORD_ID, recordId);
fragment.setArguments(bundle);*/
return fragment;
}

private void loadImageResourcesAsync(Integer recordId) {
new LoadImageResourcesAsync(getActivity()).execute(recordId);
}

}
}


layout for the activity as follows.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<fragment
android:id="@+id/view_record_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />


<!--<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/view_record_fragment"
android:name="com.xxx.xxx.view.ViewRecordActivity$ViewRecordFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="@layout/fragment_view_record" />-->


</LinearLayout>


Any help is greatly appreciated.

Answer

Basic way of adding fragments in layout is like below. You have to mention the class name of the fragment.

 <fragment android:name="com.example.android.fragments.HeadlinesFragment"
          android:id="@+id/headlines_fragment"
          android:layout_weight="1"
          android:layout_width="0dp"
          android:layout_height="match_parent" />
