So I will start off by saying that I have seen several other people post with the exact same error. However, I am at the stage where I have tried all ten different solutions and am still getting the exact same stack trace and ANR. I am using the standard Tabs + Swipe template and have not changed a single thing on it with the exception of setting the first page to return the ListView fragment I will show below.
Below is the code for my fragment. CacheFrament is simply a super class that extends android.support.v4.app.Fragment. In this case, I have tried both returning the listview only, and its parent, both to no avail.
public class RoutesFragment extends CacheFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.list_view_layout, container);
listView.setAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, new String[]{"No Routes Available"}));
return view;
}
}
This is the layout I'm using for the fragment, I originally had the ListView as the parent, which also didn't work
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/main_list_view"/>
</LinearLayout>
Finally, this is the stack trace I keep getting. Note that this is the exact same error I have gotten every single time.

Any help is greatly appreciated. This bug is basically stalling everything.
