Обнаруживать, когда система запускает загрузку

Question

Есть ли способ определить, когда система запускает загрузку и получает информацию об этом и вынуждает ее загружать в определенное место? Я googled и результаты там, где не очень полезно

Answer 1

Запустите этот класс сервиса, а затем запустите загрузку, он распечатает результат для статуса загрузки.

общественного класса MyService расширяет службы {

private Timer timer; 
private TimerTask timerTask; 
private static final int SAMPLING_RATE = 1000; 

public MyService() { 
} 

@Override 
public IBinder onBind(Intent intent) { 
    return null; 
} 

@Override 
@Deprecated 
public void onStart(Intent intent, int startId) { 
    Log.e("Download", "onstart"); 
} 

@Override 
public void onCreate() { 
    timer = new Timer(); 
    timerTask = new TimerTask() { 

     @Override 
     public void run() { 
      // Log.d(MyService.class.toString(), 
      // "tic ... "+System.currentTimeMillis()); 
      getDownloadData(); 
     } 
    }; 
    if (timer != null && timerTask != null) { 
     timer.schedule(timerTask, 0, SAMPLING_RATE); 
    } 
} 

@TargetApi(Build.VERSION_CODES.GINGERBREAD) 
@SuppressLint("NewApi") 
public void getDownloadData() { 
    DownloadManager downloadMgr = (DownloadManager) getSystemService(DOWNLOAD_SERVICE); 
    DownloadManager.Query query = new DownloadManager.Query(); 
    query.setFilterByStatus(DownloadManager.STATUS_FAILED 
      | DownloadManager.STATUS_PENDING 
      | DownloadManager.STATUS_RUNNING 
      | DownloadManager.STATUS_SUCCESSFUL); 
    Cursor c = downloadMgr.query(query); 

    if (c == null) { 
     System.out.println("--------------------------"); 
    } else { 
     if (c.moveToFirst()) { 
      System.out.println("------------End--------------"); 
      while (c.isAfterLast() == false) { 
       getStatus(c); 
       c.moveToNext(); 
      } 
     } 
    }

public void getStatus(Cursor c) { 

    int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
