I have a listview and onItemSelected, will call an Activity to get user location (his current lat and lng), this activity has no layout, then this activity automatically calls another activity which gets lat and lng of the item selected from the listview and marks both the user location and item location on the map.
This worked fine when I was testing on Emulator and Samsung Galaxy Ace, But it crashes when I’m testing on Micromax A50 and Sony Xperia.
Sad thing is that I can’t install drivers of the later 2 devices, so I cant get logcat.
Can any 1 guess what might have gone wrong??
My code for finding user location is:
public class MyLocationActivity extends Activity implements LocationListener {
private LocationManager mgr;
private String best;
public static double myLocationLatitude;
public static double myLocationLongitude;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mgr = (LocationManager) getSystemService(LOCATION_SERVICE);
dumpProviders();
Criteria criteria = new Criteria();
best = mgr.getBestProvider(criteria, true);
Log.d("best provider", best);
Location location = mgr.getLastKnownLocation(best);
dumpLocation(location);
/*Intent intent = new Intent(MyLocationActivity.this, ShowMapActivity.class);
startActivity(intent);*/
Intent intent = new Intent(MyLocationActivity.this, MapMarkerActivity.class);
startActivity(intent);
finish();
}
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
dumpLocation(location);
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
protected void onPause() {
super.onPause();
mgr.removeUpdates(this);
}
@Override
protected void onResume() {
super.onResume();
mgr.requestLocationUpdates(best, 15000, 1, this);
}
private void dumpLocation(Location l) {
if (l == null) {
myLocationLatitude = 0.0;
myLocationLongitude = 0.0;
} else {
myLocationLatitude = l.getLatitude();
myLocationLongitude = l.getLongitude();
}
}
private void dumpProviders() {
List<String> providers = mgr.getAllProviders();
for (String p : providers) {
dumpProviders(p);
}
}
private void dumpProviders(String s) {
LocationProvider info = mgr.getProvider(s);
StringBuilder builder = new StringBuilder();
builder.append("name: ").append(info.getName());
}
}
and item location is:

private MapView map = null;
