载入地图崩溃

Question

我有一个listview和onItemSelected，将调用Activity得到用户位置（他目前的LAT和LNG），这个活动有没有布局，那么这个活动会自动调用另一个活动lat和lng从listview中选择的项目，并在地图上标记用户位置和项目位置。

这工作得很好当我在模拟器和三星Galaxy王牌测试，但它崩溃当我Micromax的A50和索尼XPERIA测试上。

可悲的是，我不能安装后面的2个设备的驱动程序，所以我不能得到logcat。
任何1猜猜可能会出错吗？

我查找用户位置的代码是：

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()); 
    } 

}
