Comment envoyer un fichier à l'aide de bluetooth sur android par programmation?

De l'essayer.
Je peux envoyer un fichier à l'aide de ce code.

ContentValues values = new ContentValues();
values.put(BluetoothShare.URI, "file:///sdcard/refresh.txt");
values.put(BluetoothShare.DESTINATION, deviceAddress);
values.put(BluetoothShare.DIRECTION, BluetoothShare.DIRECTION_OUTBOUND);
Long ts = System.currentTimeMillis();
values.put(BluetoothShare.TIMESTAMP, ts);
getContentResolver().insert(BluetoothShare.CONTENT_URI, values);

Vous pouvez utiliser l'obex de la bibliothèque. Il semble qu'android n'a pas à fournir de l'obex de la bibliothèque, mais j'ai résolu le problème et la solution est affiché ici.

De plus amples Explications (s'il vous plaît commencer la lecture à partir de ici si vous êtes occupé)

1. J'ai essayé de créer un téléphone android à distance de contrôleur (et quelque chose de similaire pour le serveur telnet) qui permet de contrôler le téléphone à distance avec mon ancien téléphone.

Contenu principal :Bluetooth client FTP

1. Ma première idée était de rendre l'application, vérifiez la liste des fichiers de mon téléphone du répertoire.

2. Mais je ne sais pas comment le connecter à mon téléphone fonctionnalité du serveur ftp.

3. J'ai googlé beaucoup de choses sur la façon de se connecter à un serveur ftp via le bluetooth, mais je n'ai pu trouver que Bluetoorh serveur FTP utilisé le OBEX Protocol.

4. J'ai trouvé une matière utile (fichier PDF) dans un fil et étudié à propos OBEX demandes de connexion, les mettre et de lancer des opérations.

5. Donc j'ai finalement écrit quelques codes qui tente de se connecter à la Bluetooth FTP serveur. Je tiens à vous les montrer, mais je l'ai perdu 🙁 Les codes ont été comme vient directement d'écrire les séquences d'octets pour le flux de sortie.

6. J'ai aussi eu de la difficulté à trouver ce que l'UUID de fait l'application se connecter en tant que client FTP. Mais j'ai essayé tous les Uuid récupérées à l'aide du code ci-dessous.

   String parcels="";
   ParcelUuid[] uuids=mBtDevice.getUuids();
   int i=0;
   for (ParcelUuid p:uuids)
   {
   parcels += "UUID UUID" + new Integer(i).toString() + "=UUID.fromString((\"" + p.getUuid().toString() + "\"));\n\n";
   ++i;
   }

7. Rien ne semblait m'apporter la réponse que je voulais. J'ai donc cherché sur google plus et a découvert que non seulement je dois-je utiliser l'UUID de la 00001106-0000-1000-8000-00805f9b34fb pour se connecter à OBEX FTP server, mais aussi shold je transmettre cible de l'en-tête ** avec l'UUID **F9EC7BC4-953C-11D2-984E-525400DC9E09 lors de l'envoi de OBEX connect demande.
   Le code ci-dessous montre comment se connecter à un périphérique bluetooth serveur FTP en tant que client.

   try
   {
   mBtSocket = mBtDevice.createInsecureRfcommSocketToServiceRecord(UUID.fromString(" 00001106-0000-1000-8000-00805f9b34fb"));
   }
   catch (Exception e)
   {
   //e.printStackTrace();
   }
   Thread thread=new Thread(new Runnable() {
   public void run()
   {
   UUID uuid=UUID.fromString("F9EC7BC4-953C-11D2-984E-525400DC9E09");
   ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
   bb.putLong(uuid.getMostSignificantBits());
   bb.putLong(uuid.getLeastSignificantBits());
   byte [] bytes=bb.array();
   Operation putOperation=null;
   Operation getOperation=null;
   try
   {
   //connect the socket
   mBtSocket.connect();
   //I will explain below
   mSession = new ClientSession((ObexTransport)(mTransport = new BluetoothObexTransport(mBtSocket)));
   HeaderSet headerset = new HeaderSet();
   headerset.setHeader(HeaderSet.TARGET, bytes);
   headerset = mSession.connect(headerset);
   if (headerset.getResponseCode() == ResponseCodes.OBEX_HTTP_OK)
   {
   mConnected = true;
   }
   else
   {
   mSession.disconnect(headerset);
   }
   ...

Alors, vous êtes maintenant connecté en tant que client FTP et prêt à l'utilisation OBEX opérations d'envoi de fichiers, la demande pour les fichiers, liste de répertoires, etc.

1. Cependant, je n'ai pas envie d'attendre une heure pour envoyer ma commande pour mon téléphone android. (Et il serait inefficace si j'augmente la fréquence d'interrogation, comme tous les modes de scrutin.)

Commencer à lire à partir d'ici, si vous êtes occupé
Contenu principal: OPP OBEX

Pour la raison que j'ai mentionné ci-dessus, je greedly cherché à manipuler l'OPP qui j'ai découvert de l'OBEX de la documentation.

Vous pouvez transférer des fichiers via bluetooth normalement (sans définir votre protocole et de la construction d'une nouvelle application de bureau juste pour lui) à votre ordinateur, à droite? Puis de l'envoyer à l'OBEX OPP, boîte de réception service qui s'exécute en mode natif sur votre bureau windows de l'ordinateur est la meilleure solution. Alors, comment pouvons-nous nous connecter à l'OPP (Obex Object Push) de la boîte de réception service?

1. Installation OBEX bibliothèque
   Ajouter import javax.obex; à votre code source.
   Si votre compilateur ne supporte pas OBEX bibliothèque, télécharger les sources et les ajouter à votre projet de ici.
2. Mettre en œuvre ObexTransport
   Vous devez fournir une classe qui implémente ObexTransport à la bibliothèque lorsque vous l'utilisez. Il définit la façon dont la bibliothèque doit envoyer des données (comme par RFCOMM, TCP,...). Un exemple de mise en œuvre est ici. Cela peut entraîner certains d'exécution ou des erreurs de compilation comme there's no method. Mais vous pouvez partiellement corriger ceux en remplaçant les appels de méthode à des constantes comme return 4096 au lieu de return mSocket.getMaxTransmitPacketSize();, outcommenting la if déclarations de public int getMaxTransmitPacketSize(). Ou vous pouvez essayer d'utiliser réflexion pour obtenir ces méthodes d'exécution.
3. Obtenir BluetoothSocket
   Obtenez un bluetooth socket en utilisant mBtDevice.createInsecureRfcommSocketToServiceRecord(UUID.fromString(" 00001105-0000-1000-8000-00805f9b34fb" )); Et appel connect().
4. Créer ClientSession
   Créer une instance de votre ObexTransport mise en œuvre, et de créer un nouveau ClientSession comme mSession = new ClientSession((ObexTransport)(mTransport = new BluetoothObexTransport(mBtSocket)));.

5. Envoyer OBEX demande de connexion à votre ordinateur à l'OPP, boîte de réception de service.

   HeaderSet headerset = new HeaderSet();
   //   headerset.setHeader(HeaderSet.COUNT,n);
   headerset = mSession.connect(null);
   if (headerset.getResponseCode() == ResponseCodes.OBEX_HTTP_OK)
   {
   mConnected = true;
   }

6. Envoyer OBEX mettre requêtes à l'aide du ClientSession.

   protected boolean Put(ClientSession session, byte[] bytes, String as, String type)
   {
   //TODO: Implement this method
   //byte [] bytes;
   String filename=as;
   boolean retry=true;
   int times=0;
   while (retry && times < 4)
   {        
   Operation putOperation=null;
   OutputStream mOutput = null;
   //ClientSession mSession = null;
   //ArrayUtils.reverse(bytes);
   try
   {    
   //Send a file with meta data to the server
   final HeaderSet hs = new HeaderSet();
   hs.setHeader(HeaderSet.NAME, filename);
   hs.setHeader(HeaderSet.TYPE, type);
   hs.setHeader(HeaderSet.LENGTH, new Long((long)bytes.length));
   Log.v(TAG,filename);
   //Log.v(TAG,type);
   Log.v(TAG,bytes.toString());
   putOperation = session.put(hs);
   mOutput = putOperation.openOutputStream();
   mOutput.write(bytes);
   mOutput.close();
   putOperation.close();
   }
   catch (Exception e)
   {
   Log.e(TAG, "put failed", e);
   retry = true;
   times++;
   continue;
   //e.printStackTrace();
   }
   finally
   {
   try
   {
   if(mOutput!=null)
   mOutput.close();
   if(putOperation!=null)
   putOperation.close();
   }
   catch (Exception e)
   {
   Log.e(TAG, "put finally" , e);
   retry = true;
   times++;
   continue;
   }
   //updateStatus("[CLIENT] Connection Closed");
   }
   retry = false;
   return true;
   }
   return false;
   }

7. Enfin, déconnectez.

   private void FinishBatch(ClientSession mSession) throws IOException
   {
   mSession.disconnect(null);
   try
   {
   Thread.sleep((long)500);
   }
   catch (InterruptedException e)
   {}
   mBtSocket.close();
   }

8. Puis ici, c'est une classe wrapper.
