Asmack我正在尝试通过asmack发送文件。
我的连接变量是：
SELECT YEAR(started_at) as 'Year',
MONTH(started_at) as 'Month',
COUNT(user_id) as 'Users'
FROM subs
GROUP BY YEAR(started_at),MONTH(started_at);
这是我的sendFile方法：
File mf = Environment.getExternalStorageDirectory();
String filenameWithPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + ThisDemoActivity.this.getApplicationName()+ "/test.txt" ;
private XMPPConnection connection;
sendFile(filenameWithPath, "username@ipaddress");
我能够连接到用户并发送文本，但我无法发送此文件。
输出结果为：
/* Not very reliable: Sometimes the photos reach to the receiver and sometimes not. It is not at all reliable
* http://stackoverflow.com/questions/14601198/sending-pictures-like-whatsapp
*/
public void sendFile(final String path, final String receiver) {
Thread thread = new Thread() {
public void run() {
ServiceDiscoveryManager sdm = ServiceDiscoveryManager
.getInstanceFor(connection);
if (sdm == null)
sdm = new ServiceDiscoveryManager(connection);
sdm.addFeature("http://jabber.org/protocol/disco#info");
sdm.addFeature("jabber:iq:privacy");
// Create the file transfer manager
FileTransferManager manager = new FileTransferManager(
connection);
FileTransferNegotiator.setServiceEnabled(connection, true);
// Create the outgoing file transfer
OutgoingFileTransfer transfer = manager
.createOutgoingFileTransfer(receiver + "/Adium"); //+ "/Smack"
System.out.println("Receiver of the file is "+receiver+"/Adium");
Log.i("transfere file", "outgoingfiletransfer is created");
try {
OutgoingFileTransfer.setResponseTimeout(30000);
transfer.sendFile(new File(path), "Description");
Log.i("transfere file", "sending file");
while (!transfer.isDone()) {
try {
Thread.sleep(1000);
Log.i("transfere file", "sending file status "
+ transfer.getStatus() + "progress: "
+ transfer.getProgress());
if (transfer.getStatus() == Status.error) {
Log.i("transfere file", "Errorrr isss: "
+ transfer.getException());
transfer.cancel();
break;
}
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
} catch (XMPPException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.i("transfere file", "sending file done");
}
};
thread.start();
}
为什么当我在用户中将ipaddress指定为用户名@ ipaddress / Adium时，没有找到远程服务器？
我也试过这个方法： 方法2：
使用
