感谢您关注过的问题...
我正在与ejabbered和asmack_4.1库的帮助下XMPP聊天应用。
我已经安装了PSI的Windows客户端，以与Android设备进行聊天。 我能够在设备之间进行文本聊天。 我也能够从设备发送文件，PSI客户端和PSI客户端Android设备。 但问题是将文件发送设备到设备。
我使用下面的代码来发送和接收文件：
发送文件：
public void fileTransfer(String filenameWithPath, Bitmap thumbnail, String userId) {
// FileTransferManager manager = new FileTransferManager(connection);
FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
// OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("usre2@myHost/Smack");
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(userId + "/Admin"); // "/Good" depends on server
// OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(userId + "/Directors-iMac");
File file = new File(filenameWithPath);
try {
transfer.sendFile(file, "test_file");
} catch (SmackException e) {
e.printStackTrace();
}
while (!transfer.isDone()) {
if (transfer.getStatus().equals(FileTransfer.Status.error)) {
System.out.println("ERROR!!! " + transfer.getError());
} else if (transfer.getStatus().equals(FileTransfer.Status.cancelled)
|| transfer.getStatus().equals(FileTransfer.Status.refused)) {
System.out.println("Cancelled!!! " + transfer.getError());
}
try {
Thread.sleep(1000L);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if (transfer.getStatus().equals(FileTransfer.Status.refused) || transfer.getStatus().equals(FileTransfer.Status.error)
|| transfer.getStatus().equals(FileTransfer.Status.cancelled)) {
System.out.println("refused cancelled error " + transfer.getError());
} else {
System.out.println("Success");
}
}
文件接收：
public void fileReciever(AbstractXMPPConnection connection) {
//**************************************
// Create the file transfer manager
final FileTransferManager managerListner = FileTransferManager.getInstanceFor(connection);
// FileTransferNegotiator.setServiceEnabled(connection, true);
FileTransferNegotiator negotiator = FileTransferNegotiator.getInstanceFor(connection);
Log.i("File transfere manager", "created");
// Create the listener
managerListner
.addFileTransferListener(new FileTransferListener() {
@Override
public void fileTransferRequest(FileTransferRequest request) {
Log.i("Recieve File", "new file transfere request new file transfere request new file transfere request");
Log.i("file request", "from" + request.getRequestor());
IncomingFileTransfer transfer = request.accept();
Log.i(RECIEVE_FILE_ALERT_DIALOG, "accepted");
try {
transfer.recieveFile(new File("/sdcard/" + request.getFileName()));
while (!transfer.isDone() || (transfer.getProgress() < 1)) {
Log.i(RECIEVE_FILE_ALERT_DIALOG, "still receiving : " + (transfer.getProgress()) + " status " + transfer.getStatus());
if (transfer.getStatus().equals(FileTransfer.Status.error)) {
// Log.i("Error file",
// transfer.getError().getMessage());
Log.i("Recieve File",
"cancelling still receiving : "
+ (transfer.getProgress())
+ " status "
+ transfer.getStatus());
transfer.cancel();
break;
}
}
} /*catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/ catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
//**************************************
}
注意：在文件传输（）方法中，我使用下面一行：
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(userId + "/Admin"); // "/Good" depends on server
我能够从Android设备将文件发送到PSI的桌面应用程序，反之亦然，但我不能Android设备之间传输文件。
