Dear Android developer,

our research group is studying factors negatively impacting the success of Android apps (e.g., usefulness of the app, bad usability, etc). Given your experience in Android apps development, we kindly ask you to dedicate 30 mins of your time in answering few short questions on this topic.

You can find the online questionnaire at the URL:

If you choose to participate in our survey, please send us your answers by November, 20th 2013.

Thank you very much for your effort.

Best regards,
Gabriele Bavota
