fragment side by side

[piggybank1974]

what I'm trying to do is in portrait mode display a fragment, in landscape mode display two fragments side by side.

 

it all seems to work fine until I rotate the emulator from landscape to portrait then the app crashes with this:

 

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.fragmentapp/com.fragmentapp.MainActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x7f030002

 

it all works fine if I put the fragments in the XML but I'm trying to call them programically with this:

 

 

@Override

protected void onCreate(Bundle savedInstanceState)

{

FragmentTransaction mft = getFragmentManager().beginTransaction();

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

 

FragmentOne mFragmentOne = new FragmentOne();

//getFragmentManager().beginTransaction().add(R.id.container, mFragmentOne).commit();

mft.add(R.id.leftfragment, mFragmentOne);

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)

{

FragmentTwo mFragmentTwo = new FragmentTwo();

mft.add(R.id.rightfragment, mFragmentTwo);

//getFragmentManager().beginTransaction().add(R.id.container, mFragmentTwo).commit();

}

else

{

FrameLayout FragmentContainer = (FrameLayout) findViewById(R.id.rightfragment);

if (FragmentContainer != null)

{

getFragmentManager().beginTransaction().remove(new FragmentTwo()).commit();

}

 

}

mft.addToBackStack(null);

mft.commit();

}

 

I do have fragmentone.xml in layout folder where I have fragmetone.xml/fragmenttwo.xml in layout-land folder if this helps??

 

any body got any ideas!
