幫助help..huu致命異常：＃的AsyncTask 1

林有一個問題here..seems當我運行它...然後點擊按鈕來查看地圖由路由出現在codes..but沒有錯誤地圖......它似乎突然間關閉了。那是爲什麼？請幫我啦..

即時通訊開發一個應用程序讀取我的當前位置，並創建路由向A位置..

這裏是代碼：

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; 
       }

爲了您的信息，我已經把許可權在我的清單..

u能發現什麼導致錯誤？在code..but沒有錯誤時沒有審查我的路線圖.. :(感謝網友

E/AndroidRuntime（5368）：由：java.lang.SecurityException異常： ConnectivityService：無論用戶10228也不當前進程 android.permission.ACCESS_NETWOR K_STATE。

確保你已經添加android.permission.ACCESS_NETWORK_STATE許可，不得以AndroidManifest.xml文件

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

編輯：

從AndroidManifest.xml刪除

<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" 
/>

這個代碼，並把它的任何XML佈局內您項目中的res/layout文件夾

根據你的日誌，你沒有這個權限

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

此權限允許您訪問狀態您的 設備的網絡設備（WIFI，3G，藍牙，等等。）的

不是100％肯定，但似乎你是因爲你嘗試檢查網絡可用性從做背景。你可以嘗試在onxreexecute中檢查它嗎？

是Droider，它是..我應該改變它嗎？ –

是的，我通常會在「新BackgroundTask（this，loc，destination）.execute（）;」之前的主線程中檢查網絡可用性。我認爲這應該工作，如果你把支票在那裏 – Calvin

檢查？如何做@Droider –
