android.view.InflateException - cannot find reason

Question

This is my fragment inputtext_fragment.xml:

<?xml version="1.0" encoding="utf-8"?>
<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/inputtextfragm"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <LinearLayout
        android:id="@+id/inputtext_layout"
        android:visibility="invisible"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        ...>

        ...

    </LinearLayout>
</fragment>

inputText fragment in java:

package de.company.android.inputtext;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class InputTextFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        // Inflate the layout for this fragment
        try {
            return inflater.inflate(R.layout.inputtext_fragment, container, false);
        }
        catch (Throwable t) {
            t.printStackTrace();
            return null;
        }
    }
}

This is the activity layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layout"
    tools:context="de.company.android.testview.MainActivity"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000">

    ...

    <fragment
        android:id="@+id/console"
        android:name="de.company.android.inputtext.InputTextFragment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</RelativeLayout>

I get the following error on launch, when the content view of the activity is set onCreate():

I cannot find out what is wrong. The activity and the fragment are in different modules, but everything is configured right so that the de.company.android.inputtext utils are correctly referenced.

You're trying to inflate the fragment into itself. The layout of a fragment does not have fragment as root. Use a regular view group such as FrameLayout or LinearLayout. — Eugen Pechanec

Your input_text_fragment.xml should not be inside of a Fragment tag. It should be inside the appropriate type of Layout. The fragment tag goes only in main_activity.xml where you want the fragment to appear.
