Even though I installed Eclipse through the link that you posted, I get bunch of errors.

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

    // Show the Up button in the action bar.
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    // Show the dummy content as text in a TextView.
    if (mItem != null) {
        ((TextView) rootView.findViewById(R.id.blogpost_detail))
                .setText(mItem.content);
    }

    if (findViewById(R.id.blogpost_detail_container) != null) {
        // The detail container view will be present only in the
        // large-screen layouts (res/values-large and
        // res/values-sw600dp). If this view is present, then the
        // activity should be in two-pane mode.
        mTwoPane = true;

        // In two-pane mode, list items should be given the
        // 'activated' state when touched.
        ((BlogPostListFragment) getSupportFragmentManager()
                .findFragmentById(R.id.blogpost_list))
                .setActivateOnItemClick(true);
    }
