在 Android 应用程序中使用 smack 进行文件传输。

这个错误出现在日志中。

我在这里使用以下代码

    ServiceDiscoveryManager sdm = ServiceDiscoveryManager.getInstanceFor(Main.connection);
    if (sdm == null)
        sdm = new ServiceDiscoveryManager(Main.connection);
    sdm.addFeature("http://jabber.org/protocol/disco#info");
    sdm.addFeature("jabber:iq:privacy");

   FileTransferNegotiator.setServiceEnabled(Main.connection, true);
   FileTransferManager manager = new FileTransferManager(Main.connection);
  OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(id
           + "/Smack");

   Log.i("transfere file", "outgoingfiletransfere is created");
    try{
        //OutgoingFileTransfer.setResponseTimeout(60000);
        transfer.sendFile(new File(txt_file.getText().toString()), "You won't believe this!");

        if (transfer.getStatus().equals(Status.cancelled)
                || transfer.getStatus().equals(Status.refused)) {
                Log.d("Cancel", ""+transfer.getError());
                System.out.println("Cancelled!!! " + transfer.getError());
            }

        Log.i("transfere file", "sending file");
        Log.d("FTTRY", "m in ft TRY");
        btn_transfer.setText("Browse");
        txt_file.setText("click on browse n Select File");
        send_flag = true;
    }catch (Exception e) {
        Log.d("FTCATCH", "m in ft catch");
        btn_transfer.setText("BrowseC");
        send_flag = true;
    }

    while(!transfer.isDone()) {
        try{
           Thread.sleep(1000);
        }catch (Exception e) {
        }
          Log.i("transfere file", "sending file status "
                      + transfer.getStatus() + "progress: "
                      + transfer.getProgress());
       if(transfer.getStatus().equals(Status.error)) {
             System.out.println("ERROR!!! " + transfer.getError());
       } else {
             System.out.println(transfer.getStatus());
             System.out.println(transfer.getProgress());
             Log.d("PROG", "m in ft progress");
       }
      try{
       Thread.sleep(1000);
      }catch (Exception e) {
    }
 }

我通过执行以下过程解决了同样的问题。

我在用asmack-2010.05.07-源在 android-2.2 的 eclipse 中。

寻找 asmack.conf 中的 ProviderManager 类。替换以下代码

Enumeration providerEnum = classLoader.getResources(
                        "/META-INF/smack.providers");

有了这个

Enumeration providerEnum = classLoader.getResources(
                        "/data/smack.providers");

之后你需要打补丁。在创建之前添加以下函数new XMPPConnection。您可以通过以下方式调用此函数

 configure(ProviderManager.getInstance());

这就是方法。

public void configure(ProviderManager pm) {

    //  Private Data Storage
    pm.addIQProvider("query","jabber:iq:private", new PrivateDataManager.PrivateDataIQProvider());


    //  Time
    try {

        Log.w("TestClient", "Can't load class for org.jivesoftware.smackx.packet.Time");
