I’ve been trying to bring file transfer capabilities into my mobile client and have been running into major issues. I’ve pretty much followed the code example herehttp://harryjoy.com/2012/08/18/file-transfer-in-android-with-asmack-and-openfire /

For Sending a file, I’m getting this

E/AndroidRuntime( 3756): FATAL EXCEPTION: File Transfer jsi_20634193635998184

E/AndroidRuntime( 3756): java.lang.ClassCastException: org.jivesoftware.smack.ut

il.PacketParserUtils$UnparsedResultIQ cannot be cast to org.jivesoftware.smackx.

and for recieving, I’m getting this

E/AndroidRuntime( 3377): java.lang.NullPointerException

Any ideas or advice?

Which aSmack version are you using?

Besides I can only recommend reading https://github.com/Flowdalic/asmack/wiki/aSmack-XMPP-File-Transfer

I’m using verision .8, the same that comes in the latest version of Yaxim. I managed to get it to send a file by putting

SmackAndroid.init(mService); as the first line of my sendFile Method, however, I still get an error with recieving a file. transfer.recieveFile() and transfer.recieveFile(file) both do not work and cause a null point exception in my code.

Put some small amount of code for better understadning …
