我在这里使用了以下代码
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)
【问题讨论】：
您使用的是哪个版本的 smack？ asmack15 我从 5 天开始尝试，但仍然无法通过 smack 传输文件。如果您对此有任何想法，请提供帮助 @Hussain 我用过这个版本的 smack :-asmack-android-7-beem.jar @Akash：试试这个解决方案community.igniterealtime.org/thread/30695 @Hussain 我试过这个链接。但我的问题没有解决...... 【参考方案1】：我通过执行以下步骤解决了同样的问题。
我在 Eclipse 中为 android-2.2 使用 asmack-2010.05.07-source。
转到 asmack 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");
在这之后你需要做一个补丁。在创建之前添加以下函数
new XMPPConnection。您可以通过
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
pm.addIQProvider("query","jabber:iq:time", Class.forName("org.jivesoftware.smackx.packet.Time"));
catch (ClassNotFoundException e)

我已经尝试过了。但我的问题仍然存在。这不能解决。 如何为我的 android 项目包含 asmack 库。我遇到了很多错误【参考方案2】：谢谢， 但我解决了我的问题.. 问题是对方用户没有登录。所以我刚刚安装了sparkx clinet表单http://www.igniterealtime.org/downloads/download-landing.jsp?file=spark/spark_2_6_3.exe并使用其他用户登录，就是这样。
以下是完整的工作代码。 你需要在 General.java 中设置你的服务器和端口 我也有固定用户在活动，所以你需要根据你的配置来改变它。
