Exception while inflating Fragment with RadioGroup/Button

Question

I am creating a simple fragment class extending Fragment with just a single line code. My fragmentXML only has textview & RadioGroup/Button. It is damn simple but still not able to know the error. :-(

Fragment Class

package com.example.arslan.fragments;
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class colorFragment1 extends Fragment {

public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedBundleInstance)
{
        return inflater.inflate(R.layout.color_fragment_layout,container,false);
}
}

color_fragment_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Select Color"
/>

<RadioGroup
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal">
<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New RadioButton"
    android:id="@+id/radioButton"
    android:layout_gravity="center_horizontal" />
</RadioGroup>
</LinearLayout>

MainActivity package com.example.arslan.fragments;

import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.graphics.Color;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity{

LinearLayout parent;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    parent = (LinearLayout)findViewById(R.id.parent);
    FragmentManager colorFragmentManager = getFragmentManager();
    FragmentTransaction colorFragmentTransaction = colorFragmentManager.beginTransaction();
    colorFragment1 colorFragmentObject = new colorFragment1();
    colorFragmentTransaction.add(R.id.fragment_container,colorFragmentObject);
    colorFragmentTransaction.commit();
}

activity_main

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:id="@+id/parent"
    tools:context=".MainActivity">
 <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Example Fragment Communication"/>
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:id="@+id/fragment_container"
    android:layout_marginTop="60dp"
    android:layout_marginLeft="20dp">
</RelativeLayout>
</LinearLayout>

Note: If I remove the radiogroup & radiobutton from the xml file. The code works fine. So, please do not suggest anything that involve removing these view elements.
