Android Fragments Get Issue With getFragmentManager()

I want to add a fragment into relative layout and here's my MainActivity.java :

import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

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

        FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

        FragmentOne f1 = new FragmentOne();
        fragmentTransaction.add(R.id.fragment_container, f1);
        fragmentTransaction.commit();

    }
}

when I run that code, I got this error :

Error:(15, 61) error: incompatible types: android.app.FragmentManager cannot be converted to android.support.v4.app.FragmentManager

how to add fragment into relative layout? I tried to change getFragmentManager(); into getSupportFragmentManager();

also didn't work. any idea what's wrong with this?

UPDATE : here's what I got when I change getFragmentManager(); into getSupportFragmentManager();

enter image description here

Check your imports. You're importing android.support.v4.app.FragmentManager, so the variable FragmentManager fragmentManager is of type android.support.v4.app.FragmentManager but getFragmentManager returns the platform version of fragment manager android.app.FragmentManager, so these are incompatible types.

Since you are using AppCompatActivity, you should be using getSupportFragmentManager.

You say

I tried to change getFragmentManager(); into getSupportFragmentManager(); also didn't work.

What does "also didn't work" mean? That should work.
