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 from android.app.FragmentManager to android.support.v4.app.FragmentManager" And that is the main reason that i cannot implement it.I have already imported android.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(); } }; } java android android-listview android-fragments share | improve this question edited May 22 '13 at 11:26 asked May 22 '13 at 11:16 sakshi 78 1 6

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 standard android.Activity to get this method.
