There is some delay in general progress these days because I'm busy with other projects. But I still plan to create at least basic testing support and make it available soon. If everything goes well I'll be able to create a new update in a week or two. Stay tuned.
In the meantime I did some experiments and worked with nbandroid as a user. The result is couple of bugs discovered and a few ideas what to do next. And example is a fix for launch action that asked for target device even if the build failed. This is integrated now and more small fixes like this one can follow.
