帮助帮助..huu

我在这里遇到问题..似乎代码中没有错误..但是当我运行它时...并单击按钮查看地图包括路由地图..它突然关闭了..这是为什么？请朋友帮帮我..

我正在开发一个应用程序来读取我当前的位置并创建到 A 位置的路线..

以下是代码：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);

    onNewIntent(getIntent());

    Drawable marker = getResources().getDrawable(R.drawable.marker);
    Drawable marked_places = getResources().getDrawable(R.drawable.feringgi_map);

    mymap = (MapView)findViewById(R.id.mymap);
    controller = mymap.getController();
    // extract MapView from layout
    mymap.getController().setZoom(15);
    mymap.setBuiltInZoomControls(true);
    mymap.setSatellite(false);

    // create an overlay that shows our current location
    myLocationOverlay = new MyLocationOverlay(this, mymap);

    // add this overlay to the MapView and refresh it
    mymap.getOverlays().add(myLocationOverlay); 
    mymap.postInvalidate();

    myLocationOverlay.runOnFirstFix(new Runnable() {

        @Override
        public void run() {
            controller.setZoom(10);
            controller.animateTo(myLocationOverlay.getMyLocation());                
        }
    });

    zoomToMyLocation();

   switch(selecteditem)
   {
   case 0:        switch(selectedsubitem){
            case 0://Place A       
                    locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
                  locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
                  Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                      if (location !=null) {
                      loc=location;
                  }
                  GeoPoint destination = getPoint(3.144341, 101.69541800000002);
                  new BackgroundTask(this, loc, destination).execute();
                break;              
}
}

 class BackgroundTask extends AsyncTask<Void, Void, Void> {

        private Location location;
        private GeoPoint dest;
        private Route route;
        private Activity activity;
        private ProgressDialog dialog;
        private RouteOverlay routeOverlay;

        public BackgroundTask(Activity activity, Location loc, GeoPoint dest) {
            location=loc; 
            this.dest=dest;
            this.activity=activity;
            dialog = new ProgressDialog(activity);
        }

        @Override
        protected void onPreExecute() {
            dialog.setCancelable(false);
            dialog.setTitle("Loading...");
            dialog.setMessage("Calculating Route...");
            dialog.setButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(final DialogInterface dialog, final int id) {
                  cancel(true);
                  MyMap.this.finish();
                }});
            dialog.show();
        }

protected Void doInBackground(Void... params) {
                if(isNetworkAvailable())
                {
                    if(haveInternet())
                    {   try{
                            route = directions(new GeoPoint((int)(location.getLatitude()*1.0E6),(int)(location.getLongitude()*1.0E6)), dest); 
                        }
                        catch (NullPointerException e){ }
                    }
                    else
                    {   return null;
                    }
                }
                else
                {   return null; }

                return null;
                }

这是日志猫（更新）..：

        </application>

    </manifest>

供您参考，我已经将 ACCESS_NETWORK_STATE 放入我的清单中。

你能找出导致错误的原因吗？代码没有错误..但它未能查看我的路线图..:( 感谢朋友

根据您的日志，您没有此权限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

此权限允许您访问设备的网络设备状态（Wifi、3G、蓝牙等）

E/AndroidRuntime(5368)：原因：java.lang.SecurityException：ConnectivityService：用户 10228 和当前进程都没有 android.permission.ACCESS_NETWORK_STATE。

确保您已在文件中添加android.permission.ACCESS_NETWORK_STATE权限为AndroidManifest.xml

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>

编辑 ：

消除

<com.google.android.maps.MapView
android:id="@+id/mymap"
android:clickable="true"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="XXXX"
/>

此代码来自AndroidManifest.xml并将其放在项目中 res/layout 文件夹中的任何 xml 布局中

不是 100% 肯定，但似乎你得到了这个，因为你试图在后台检查网络可用性。您可以尝试在onpreexecute中检查它吗？
