I think this is not related to Android only. There is a problem when the PGP is not properly send to the coordinator, it can happen with any API request.

Does it always happen to you? even with a new robot?

I noticed this for the first time while reusing the robot. However when I used the same robot on the webinterface it worked fine again.
I have not tried with a new robot on android, but the last few trades worked fine on android. All with the same coordinator (Temple).
Now that this bug occurred on android I couldn't continue in any way, I tried restarting the app etc but it wouldn't let me continue, like if some trade related state got corrupted?

Did you try removing the robot and recovering?

Just tried, that seems to get the app out of this stuck state again. Now it recognized that the trade already ended instead of being stuck at the error message.
