0.2.9 includes a bug which causes MissingPluginException in iOS. It is reported in #94 and fixed in 0.2.10. Can you please use 0.2.10?

Btw, your application works on my test environment.

But I can't reproduce this error with your test app. I tested it myself and it worked for me. Posted the logs in my previous message. Can you try cloning your application into another directory and testing it from there?

By the way, there are other reasons that cause MissingPluginException. Can you google about them and try suggestions listed there?
