下載apk文件。在AVD上工作正常，但在真實的手機上達不到

你好，我試圖從網絡服務器下載apk文件到我的Android應用程序（/下載）目錄。問題是：在AVD上工作正常，但在我的真實手機S2不下載這個apk文件。請HELLP :)下載apk文件。在AVD上工作正常，但在真實的手機上達不到

代碼：`

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

    BroadcastReceiver receiver = new BroadcastReceiver() { 
     @SuppressLint("NewApi") 
     @Override 
     public void onReceive(Context context, Intent intent) { 
      String action = intent.getAction(); 
      if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) { 

       // openFile(); 

      } 
     } 
    }; 

    registerReceiver(receiver, new IntentFilter(
      DownloadManager.ACTION_DOWNLOAD_COMPLETE)); 


    /* 
    //del old file 
    File fileUpdate = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/"+fileName); 
    if(fileUpdate != null){ 
     fileUpdate.delete(); 
    }*/ 

    startDownload(); 
} 

@SuppressLint("NewApi") 
public void startDownload() { 
    try{ 
     dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE); 
     Request request = new Request(
       Uri.parse("http://10.10.10.10/andr_test/download_new_version/appUpdate.apk")); 
     enqueue = dm.enqueue(request); 
    } catch (Exception e) { 
     Log.e("Can't download file", "Can't download file-" + e.getMessage()); 
    } 
}`
