    <p>It seems that when you touch Back dispatchKeyEvent() receive twice the KeyEvent KEYCODE_BACK, so I suggest you do it this way :</p> <pre><code>public class FileList extends ListActivity { private File file; private List&lt;String&gt; myList; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); myList = new ArrayList&lt;String&gt;(); String root_sd = Environment.getExternalStorageDirectory().toString(); file = new File( root_sd + "/external_sd" ) ; File list[] = file.listFiles(); for( int i=0; i&lt; list.length; i++) { myList.add( list[i].getName() ); } setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, myList )); } protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); File temp_file = new File( file, myList.get( position ) ); if( !temp_file.isFile()) { file = new File( file, myList.get( position )); File list[] = file.listFiles(); myList.clear(); for( int i=0; i&lt; list.length; i++) { myList.add( list[i].getName() ); } Toast.makeText(getApplicationContext(), file.toString(), Toast.LENGTH_LONG).show(); setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, myList )); } } @Override public void onBackPressed() { String parent = file.getParent().toString(); file = new File( parent ) ; File list[] = file.listFiles(); myList.clear(); for( int i=0; i&lt; list.length; i++) { myList.add( list[i].getName() ); } Toast.makeText(getApplicationContext(), parent, Toast.LENGTH_LONG).show(); setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, myList )); } </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
