Change the code,

if ((findViewById(R.id.fragment_container) != null)
            && (findViewById(R.id.detail_fragment_container) != null)) {
        mTwoPane = true;
    } else {
        mTwoPane = false;
    }

by

if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
    //Do some stuff
mTwoPane = true;
} else{
 mTwoPane = false;
}

hope it will help you
