    <p>I'm trying to create and draw the route from the current device position to a defined destination. When i test the app on a Tablet, it works well. But when i test it on smartphone, it crashes. Here's the code that i wrote:</p> <pre><code> public class RoutePath extends MapActivity { /** Called when the activity is first created. */ MapView mapView; private RoutePath _activity; GeoPoint srcGeoPoint,destGeoPoint;

mapView.setClickable(true); setContentView(mapView); _activity = this; LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);//work with network longitude = location.getLongitude(); latitude = location.getLatitude(); double src_lat = latitude; double src_long = longitude; double dest_lat = 38.1267303; double dest_long = 13.3466097; String n = String.valueOf(src_long); Log.d("asd",n);

} } </code></pre> <p>I guess that the problem could be the high RAM's use, because im' trying to create a route between two places away over 1200 km, and so the tablet RAM can bear this process, but not the smartphone. The Android version that i'm using to test is 4.0.3, both on the tablet than on smartphone. Any suggestions?</p>

    3. COYou can get logs later using `adb logcat -d <filename>`. Also, depending on the way your app functions, you could potentially use an emulator and spoof GPS coordinates using the Emulator Control part of Android Device Monitor (also it's in the DDMS perspective in Eclipse).

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).
