    <p>I'm trying to implement returning from an Activity without needing to refresh the screen. As far as I see, there are 4 possible states to handle:</p> <ol> <li>Both "Use wireless networks" and "Use GPS satellites" are disabled (user is directed to My Location preferences and not allowed to continue if either are are disabled)</li> <li>One of these two are enabled (1 of 2 possibilities) 3, Both are enabled</li> </ol> <p>My problem is that after returning from other Activities in my app, setupWebView() is called every time causing a screen refresh delay.</p> <p>The refresh is somewhat necessary returning from the preferences (e.g. GPS after enabling gets a fix), but certainly not after returning from an Activity as the time delay in re-painting the screen is distracting and slows down the workflow of my app.</p> <p>Could someone please advise how to handle this within my onResume() so to avoid all the setupWebview calls.</p> <p>Here is the code from my onResume() within my main Activity:</p> <pre><code> @Override protected void onResume() { if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) &amp;&amp; !locationManager .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) createMyLocationDisabledAlert(); if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 500, 0, this); mostRecentLocation = locationManager .getLastKnownLocation(LocationManager.GPS_PROVIDER); if (mostRecentLocation != null) setupWebView(); else { mostRecentLocation = locationManager .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); setupWebView(); } } else if (locationManager .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 500, 0, this); mostRecentLocation = locationManager .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); if (mostRecentLocation != null) setupWebView(); else { mostRecentLocation = locationManager .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); setupWebView(); } } // locationManager.requestLocationUpdates(provider, 500, 0, this); // mostRecentLocation = locationManager.getLastKnownLocation(provider); // } else // mostRecentLocation = locationManager // .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); super.onResume(); } </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.
