android.view.ViewGroup$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams

[wiseman]

Using [lein-droid "0.2.0-preview4"], I can compile the app, but when I run it on my Galaxy Nexus with Android 4.2.2 I get the following:

A solution that worked for me was to change the dependency from [neko/neko "3.0.0-preview3"] to [neko/neko "3.0.0"].

[krisc]

I'm hesitant to merge your pull request at the moment because the latest stable of neko (and lein-droid) causes problems for some people (myself included). In my tutorial, I encourage people to use preview4 for both. From what I gather from alex (the maintainer of lein-droid) these previews are pretty close to the stable versions. Does preview4 work for you?

If anything, the dependency should at least be 3.0.0-preview4 until we figure out why 3.0.0 is causing trouble. If preview4 in fact does work for you, I'll change the dep from preview3 to preview4 because that seems to work for most people.

[wiseman]

Yes, 3.0.0-preview4 works for me. What sorts of problems did you see with 3.0.0? (I want to know what to look out for.)

[krisc]

I don't have time to recreate the problem I was having right now, but it wouldn't compile. If I remember correctly, it was an error similar to yours.

Great that preview4 works for you. I'll close this for now and change the dep to preview4 when I get around to it.
