I am creating an app using Fragments for tablet.I have so far created some buttons on the left side and the fragments appear on clicking the buttons.

But i am experiencing error in my MainActivity.java file "Type mismatch error:cannot convert fromandroid.app.FragmentManager to android.support.v4.app.FragmentManager" And that is the main reason that i cannot implement it.I have already importedandroid.support.v4.app.FragmentManager.

How can i resolve my problem?

My code for MainActivity.java

      import android.app.Activity;import android.os.Bundle;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentTransaction;import android.view.View;import android.widget.Button;public class MainActivity extends Activity {    Fragment fragment;    Button btn1,btn2,btn3,btn4,btn5,btn6;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btn1=(Button)findViewById(R.id.btn1);        btn2=(Button)findViewById(R.id.btn2);        btn3=(Button)findViewById(R.id.btn3);        btn4=(Button)findViewById(R.id.btn4);        btn5=(Button)findViewById(R.id.btn5);        btn6=(Button)findViewById(R.id.btn6);        FragmentManager fm=getFragmentManager();        FragmentTransaction ft=fm.beginTransaction();        StartFragment myfragment=new StartFragment();        ft.add(R.id.myfragment,myfragment);        ft.commit();        btn4.setOnClickListener(btnOnClickListener);        btn5.setOnClickListener(btnOnClickListener);        btn6.setOnClickListener(btnOnClickListener);    }        Button.OnClickListener btnOnClickListener=new Button.OnClickListener(){            @Override            public void onClick(View v)            {                Fragment newfragment;                if(v==btn1)                {                    newfragment=new Fragment1();                }                else if(v==btn2)                {                    newfragment=new Fragment2();                }                else if(v==btn3)                {                    newfragment=new Fragment3();                }                else if(v==btn4)                {                    newfragment=new Fragment4();                }                else if(v==btn5)                {                    newfragment=new Fragment5();                }                else if(v==btn6)                {                    newfragment=new Fragment6();                }                else                 {                    newfragment=new StartFragment();                }                FragmentTransaction transaction=getFragmentManager.beginTransaction();                transaction.replace(R.id.myfragment,newfragment);                transaction.addToBackStack(null);                transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);                transaction.commit();            }        };        }

You need to use getSupportFragmentManager() in your code, not getFragmentManager() - see here for more details: http://developer.android.com/reference/android/support/v4/app/FragmentActivity.html#getSupportFragmentManager()

You also need to extend your class from android.support.v4.app.FragmentActivity, not just from standardandroid.Activity to get this method.
