问题描述
我正在尝试使用 asmack-2010.05.07.jar 共享文件，我发送成功但收到带有 ExecutionException 的 0kb 文件.
I'm trying for sharing files using asmack-2010.05.07.jar, I'm sending successfully but receiving 0kb file with ExecutionException.
我的发送和接收代码是:
My sending and receiving code is:
发送文件:
private void sendFile(XMPPConnection connection) {

FileTransferNegotiator.setServiceEnabled(connection, true);

FileTransferManager manager = new FileTransferManager(connection);
// Create the outgoing file transfer
String toName = to + "@" + getResources().getString(R.string.service)
+ "/Smack";
transfer = manager.createOutgoingFileTransfer(toName);
Log.i(TAG, "send-TO: " + toName);
// Send the file
try {
File myFile = new File(PICKUP_LOC);
if (myFile.exists()) {
Toast.makeText(MyChat.this, "File Exist---", 1).show();
transfer.sendFile(myFile, "You won't believe this!");
} else {
Toast.makeText(MyChat.this, "NOt Exist---", 1).show();
}
} catch (XMPPException e) {
e.printStackTrace();

推荐答案
正如我们所讨论的 此处 - Smack 在文件传输实现中存在一些错误:如果发起方提供了 bytestreams 和 ibb 方法，响应方接受两者(这是错误的)) 方法，在下一个行程发起者提供 bytestreams 流主机，响应者选择一个，然后文件传输应该从选定的流主机开始.但是发起者错误地启动了 ibb 方法(原文如此！).您可以尝试在代码中调用 FileTransferNegotiator.IBB_ONLY = true;，但强烈建议向 Smack 开发人员提交错误报告.
As we discussed here - Smack have some bugs in file transfer implementation: in you case initiator offered bytestreams and ibb methods, responder accept both (which is wrong) methods, on the next trip initiator offer bytestreams streamhosts, responder selects one, and there file transfer should start with selected streamhost. But initiator wrongly starts ibb method(sic!). You can try call FileTransferNegotiator.IBB_ONLY = true; in your code, but strongly recommended to submit bug report to Smack developers.
