接收器下載 - Android

我正在研究哦如何觸發我的應用程序，如果任何下載發生在任何應用程序。我有使用DownloadManager的代碼片段，只有當我的應用程序執行任何下載時，纔會通知我，但我從來沒有找到任何解決方案，在我的移動設備上發生任何下載，必須通知我的應用程序。 Pl建議我，如果這將是可能的。謝謝接收器下載 - Android

您可以使用BroadCastReceiver的。 –

你可以給我簡要的解釋。欣賞，如果你有任何參考。 – RAAAAM

這可能有助於http://stackoverflow.com/questions/22950893/how-to-detect-if-a-specific-app-is-being-downloaded-installed-by-the-google-play –

1-您必須製作Service才能下載後臺中的任何文件。

public class DownloadService extends Service { 

    private static final String TAG = "DownloadService"; 
    public static final int UPDATE_PROGRESS = 8344; 

    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 

     if (intent == null) { 
     } else { 

      final String urlToDownload = intent.getStringExtra("url"); 
      final ResultReceiver receiver = (ResultReceiver) intent 
        .getParcelableExtra("receiver"); 

      new Thread(new Runnable() { 

       @Override 
       public void run() { 
        try { 
         URL url = new URL(urlToDownload); 
         URLConnection connection = url.openConnection(); 
         connection.connect(); 

         int fileLength = connection.getContentLength(); 

         // download the file 
         InputStream input = new BufferedInputStream(url 
           .openStream()); 
         String localPath = Environment 
           .getExternalStorageDirectory() 
           .getAbsoluteFile() 
           + File.separator 
           + Constant.ROOT_FOLDER_NAME 
           + File.separator 
           + Constant.FOLDER_IMAGE 
           + File.separator 
           + urlToDownload.substring(urlToDownload 
             .lastIndexOf('/') + 1); 

         AppLog.Log(TAG, "Path :: " + localPath); 

         OutputStream output = new FileOutputStream(localPath); 

         byte data[] = new byte[1024]; 
         long total = 0; 
         int count; 
         while ((count = input.read(data)) != -1) { 
          total += count; 
          // publishing the progress.... 
          Bundle resultData = new Bundle(); 
          resultData.putInt("progress", 
            (int) (total * 100/fileLength)); 
          receiver.send(UPDATE_PROGRESS, resultData); 
          output.write(data, 0, count); 
         } 

         output.flush(); 
         output.close(); 
         input.close(); 
        } catch (IOException e) { 
         AppLog.Log(TAG, "********* EXCEPTION *****"); 
         e.printStackTrace(); 
        } 

        Bundle resultData = new Bundle(); 
        resultData.putInt("progress", 100); 
        receiver.send(UPDATE_PROGRESS, resultData); 
        stopSelf(); 
       } 
      }).start(); 
     } 

     return START_STICKY; 
    } 

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

2 - 那麼你必須做出ResultReceiver得到通知，而下載完成。

private class DownloadReceiver extends ResultReceiver { 

    public DownloadReceiver(Handler handler) { 
     super(handler); 
    } 

    @Override 
    protected void onReceiveResult(int resultCode, Bundle resultData) { 
     super.onReceiveResult(resultCode, resultData); 
     if (resultCode == DownloadService.UPDATE_PROGRESS) { 
      int progress = resultData.getInt("progress"); 

      if (progress == 100) { 
       // Download Complete 
      } 
     } 
    } 
}

3-呼叫下載服務

Intent intent = new Intent(context, DownloadService.class); 
intent.putExtra("url", "url to download"); 
intent.putExtra("receiver", new DownloadReceiver(new Handler())); 
startService(intent);

變化清單文件應用標籤裏面的Manifest.xml

添加標籤：

<application > 
------ 
------ 

<service android:name="PACKAGENAME.DownloadService" /> 

------ 
------ 
</application>
