I cannot change app icon when "motion-flow" is added to the Rakefile (android app)

[ulversson]

Without require "motion-flow" in the Rakefile my android project seems to be compiling fine.
After adding require "motion-flow".I'm getting an error like the one below. I'm specifying

app.icon in the Rakefile it compiles ok with this icon (located in drawable directory).
With require "motion-flow" crashes with the following message:

`build/android/Development-22/AndroidManifest.xml:4: error: Error: No resource found that matches the given name (at 'icon' with value '@drawable/icon').

I just ran in to this same problem in a non-flow app because I added flow for its JSON module. The suggested work around in #64 fixed the problem for me. This is likely to trip up many new apps and would be really good to address. 2c
