Xpra: Ticket #743: [Android Client] - "failed to negotiate a packet encoder" while trying to connect issue

Hi, When i try to connect to an Xpra Server with Android Client it displays a black screen during half a second then stops with an OK button dial "Xpra Client s'est arrĂȘtĂ©" (="Xpra Client has stopped").

On ~/.xpra/:13.log :

2014-11-21 14:55:09,229 xpra is ready.
[...]
2014-11-21 14:56:35,318 New connection received: SocketConnection(('SERVER-IP', 14444) - ('CLIENT-IP', 60897))

It is quite possible that the Android client needs updating to run against newer servers, I haven't tried it in many many months. The Android client is almost abandoned at this point unfortunately, I just don't have the time for everything.

Thanks for your feedback.

I'll try using an older Xpra server when i have time.

no matching packet encoder found!


Would normally mean that we miss bencode, but I see it in your xpra info...

I've uploaded an updated build (all but identical to the previous build, except for the version bump): http://xpra.org/beta/Android Does that work for you? (works as good as before for me on 2 android devices)

Not heard back, I assume this works OK, moving it to replace the "old" one (it's labelled 0.15, but that doesn't really matter).

Feel free to re-open if you still have issues.
