    <p>I'm a begginer with Android and currently stuck with the lession: <a href="http://developer.android.com/training/basics/firstapp/starting-activity.html">http://developer.android.com/training/basics/firstapp/starting-activity.html</a></p> <p>In the part <strong>Create the Second Activity</strong>, when I try to use the code:</p> <pre><code>public class DisplayMessageActivity extends Activity { @SuppressLint("NewApi") @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_display_message); // Make sure we're running on Honeycomb or higher to use ActionBar APIs if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB) { // Show the Up button in the action bar. getActionBar().setDisplayHomeAsUpEnabled(true); } } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: NavUtils.navigateUpFromSameTask(this); return true; } return super.onOptionsItemSelected(item); } } </code></pre> <p>I get the error below:</p> <p><strong>@SuppressLint("NewApi")</strong> -> The attribute value is undefined for the annotation type SuppressLint.</p> <p>if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.<strong>HONEYCOMB</strong>) -> HONEYCOMB cannot be resolved or is not a field.</p> <p><strong>getActionBar</strong>().setDisplayHomeAsUpEnabled(true); -> The method getActionBar() is undefined for the type DisplayMessageActivity.</p> <p><strong>NavUtils</strong>.navigateUpFromSameTask(this); -> NavUtils cannot be resolved</p> <p>Someone let me know how to solve? Here is what I imported:</p> <pre><code>import android.app.Activity; import android.os.Build; import android.os.Bundle; import android.view.MenuItem; </code></pre> <p>Many thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
