Error inflating class android.support.v4.app.fragment When running on Android 2.2

Question

I want to add support for my app to the Android Foryo.

But I cannot seem to figure the problem out. I have done many research using Google and in StackOverflow. The only thing I got is that I have to use <android.support.v4.app.fragment instead of <fragment using the support library, but that is also doesn't work!

Whenever I try to run the application it crushes and I get this error in the LogCat.

android.view.InflateException: Binary XML file line #40: Error inflating class android.support.v4.app.fragment

Java

/**

 */
package com.example;

import android.app.TabActivity;
import android.os.Bundle;

/**
 * @author

 */

public class MainActivity extends TabActivity {

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

SettingsFragment.java It's just...

package com.example;

import android.os.Bundle;

import com.nozzha.support.v4.preference.PreferenceFragment;

public class SettingsFragment extends PreferenceFragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preference_settings);
    }

}

I have edited the question and added the code of SettingsFragment.java — , Nov 22 '13 at 12:28
Did you include the compatibility package in the exported tab? As [discussed here](http://stackoverflow.com/questions/17273218/android-unable-to-instantiate-activity-didnt-find-class-on-path/17273328#17273328) — gunar, Nov 22 '13 at 12:35
Have you check out the support library's demo code? As i found out in samples the declaration is something like — saiful103a, Nov 22 '13 at 13:01

That is because your Activity does not extend the base Activity FragmentActivity. If you use Support Based Fragment, then your Activity must extend the FragmentActivity.

please try adding the constructor. public void SettingsFragment(){}. Activity needs it to properly initialize the fragment.
