    <p>In my onCreate, the following code executes:</p> <pre><code>dialog = new ProgressDialog(this); dialog.setCancelable(false); dialog.setCanceledOnTouchOutside(false); dialog.setMessage("Welcome! Initializing database... This will take just a minute"); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMax(100); dialog.setProgress(0); dialog.show(); </code></pre> <p>The dialog should only go away once an AsyncTask completes. If I click home and then return to the application the ProgressDialog should still be there, and in fact, that's what happens in the emulator. On my HTC Evo, however, the dialog does not show if I click home and return to the app.</p> <p>I also have:</p> <pre><code>@Override protected void onRestart() { super.onRestart(); try { dialog.show(); } catch(Exception e) {} } </code></pre> <p>Any ideas as to what could be causing this?</p> <p><strong>Updated (most relevant code):</strong></p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mContext = this; RecipeDbAdapter rdAdapter; int recipesInDb = 0; // Binds automatically to "@android:id/list" setContentView(R.layout.country_list); setListAdapter(new EfficientAdapter(this)); handler = new Handler() { public void handleMessage(Message msg) { Bundle b = msg.getData(); String type = b.getString("type"); String data = b.getString("data"); // If message received to advance dialog (called during initial db load) try { if (type.equals("dialog")) { dialog.incrementProgressBy(Integer.parseInt(data)); if (dialog.getProgress() &gt;= dialog.getMax()) { dialog.setProgress(dialog.getMax()); currentlyLoadingFromDb = false; dialog.dismiss(); dialog = null; } } else if (type.equals("update")) { updateLastRecipeUpdateDate(); } } catch (Exception e) { } } }; try { rdAdapter = new RecipeDbAdapter(Countries.this); rdAdapter.open(); recipesInDb = rdAdapter.fetchAllRecipesCount(); rdAdapter.close(); // Initialize database of recipes if (recipesInDb == 0) { currentlyLoadingFromDb = true; dialog = new ProgressDialog(this); dialog.setCancelable(false); dialog.setCanceledOnTouchOutside(false); dialog.setMessage("Welcome! Initializing database of recipes... This will take just a minute"); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMax(100); dialog.setProgress(0); dialog.show(); updateLastRecipeUpdateDate(); loadAT = new LoadDatabaseTask().execute(""); } rdAdapter.close(); } catch (Exception e) { } } @Override protected void onPause() { try { dialog.dismiss(); } catch(Exception e) {} super.onPause(); } @Override protected void onResume() { super.onResume(); if (dialog!=null) try { dialog.show(); } catch(Exception e) {} } @Override protected void onDestroy() { super.onDestroy(); } </code></pre> <p>} `</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.

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