    <p>I recently ran into this problem as well. I have an application with many activities all needing to access global objects (db connections, lists of data, etc) and so I overrode the Application class. To that end, I realized all I needed was a reference to the latest instance of the progress dialog in my runnable that I was using to dismiss the dialog. This is what I came up with and it gracefully survives phone reorientations:</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); mHandler = new Handler(); mApplication = (MyApplication)getApplication(); mFileStorage = (CheckBoxPreference)getPreferenceScreen().findPreference("fileStorage"); mProgressDialog = new ProgressDialog(this); mProgressDialog.setTitle("Location Update"); mProgressDialog.setMessage("Moving databases to new storage location."); mProgressDialog.setIndeterminate(true); mProgressDialog.setCancelable(false); mProgressDialog.setCanceledOnTouchOutside(false); mApplication.setProgressDialog(mProgressDialog); } @Override protected void onResume() { super.onResume(); mPreferences = PreferenceManager.getDefaultSharedPreferences(this); mPreferences.registerOnSharedPreferenceChangeListener(this); if (sUpdateThread != null &amp;&amp; sUpdateThread.isAlive()) { mProgressDialog.show(); } } @Override protected void onPause() { super.onPause(); mPreferences.unregisterOnSharedPreferenceChangeListener(this); if (sUpdateThread != null &amp;&amp; sUpdateThread.isAlive()) { mProgressDialog.hide(); mApplication.setProgressDialog(null); } } </code></pre> <p>....random stuff here....</p> <pre><code>private Runnable showProgressRunnable = new Runnable() { public void run() { mProgressDialog.show(); } }; private Runnable hideProgressRunnable = new Runnable() { public void run() { if (mApplication.getProgressDialog() != null) { mApplication.getProgressDialog().dismiss(); } } }; </code></pre> <p>My thread does an mHandler.post(showProgressRunnable) when the task starts and then does an mHandler.post(hideProgressRunnable) when the task finishes. Since the reference to the latest ProgressDialog is now stored in the Application class, I can close it out reliably since I am no longer holding on to an old object reference.</p> <p>Link for posterity: <a href="http://developer.android.com/reference/android/app/Application.html" rel="nofollow noreferrer">http://developer.android.com/reference/android/app/Application.html</a></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.
