分享强制关闭错误日志 –

我没有在模拟器中得到任何错误，它在模拟器中工作正常，但是当我在移动设备上运行它时，它正在获取强制关闭。 –

plz帮助我arpit –

我也有同样的问题。在manifest.xml中试试这个代码。它为我工作。

MainActivity：

public class WhereIActivity extends MapActivity { 


     // MapController mc; 
     MapView myMapView; 
     MapController mapController; 
     GeoPoint point; 
     MyPositionOverlay positionOverlay; 



    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_where_i); 

     MapView myMapView=(MapView)findViewById(R.id.myMapView); 

     mapController=myMapView.getController(); 


     myMapView.displayZoomControls(false); 

     mapController.setZoom(17);

你会PLZ给我的代码我的邮箱ID：[email protected]谢谢提前 –

请投我的答案，它用于别人 – Ram

我试图但它的显示投票需要15个声望.plz帮助我KARTHI.plz –

此行

addresses = gc.getFromLocation(location.getLatitude(),location.getLongitude(), 1);

可以给你一个空指针异常，因为其如果块之外，这是未处理的，因为你是只在该特定的尝试块中捕获IOException。这可能不是解决您遇到的问题的方法，但我想我会指出它。

这也是一个明显的建议，但不能以编程方式打开GPS，必须手动执行此操作。您是否已验证手机中的GPS已打开？
