    <p>I'm implementing an app that gets your location when you open it. It only gets it when the activity is created, so I don't need a <code>LocationListener</code>. I'm testing it in two real devices.</p> <p>First I try to get the location using <code>GPS_PROVIDER</code>. If the result is NULL, I use <code>NETWORK_PROVIDER</code>. Since I'm testing it inside a building is to be expected that I won't be able to get the location using the GPS provider.</p> <p>In one of the devices the location using <code>GPS_PROVIDER</code> is NULL, and the <code>NETWORK_PROVIDER</code> returns the correct location. But in the other device the location using GPS_PROVIDER is not NULL, but it's wrong (it's in a different city than the one I'm currently am!). This is the code I'm using:</p> <pre><code>private void getPosition() { locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); myloc = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); if(myloc == null) myloc = locManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); if(myloc != null){ Geocoder geoCoder = new Geocoder(getBaseContext(), Locale.getDefault()); try{ List&lt;Address&gt; addresses = geoCoder.getFromLocation(myloc.getLatitude(), myloc.getLongitude(), 1); if(addresses.size()&gt;0){ String add = ""; for(int i=0; i&lt;addresses.get(0).getMaxAddressLineIndex(); i++) add += addresses.get(0).getAddressLine(i)+"\n"; placeEdit.setText(add); } }catch(IOException e){ e.printStackTrace(); } } } </code></pre> <p>How can I know the location returned by the GPS provider is wrong? Should I look the network provider first and if it's null use the gps? This app is supposed to be used outside, so I'd like to use the gps first since it's more accurate.</p> <p>Thanks!</p>

    2. COThanks! Now I choose network or GPS depending on the time of the Location, like that post suggested.

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.
