Help! Looking for Android developers for our research

Hello,
for a research project focused on Android, jointly carried on by the Gran Sasso Science Instutite, the Università degli Studi dell'Aquila and the Vrije Universiteit Amsterdam, we are looking for Android developers willing to fill out a short survey.

Only requirements are:
- Good knowledge of English language.
- To have published (either alone or in a company/group) at least one Android app currently available on the Google Play Store.

The survey can be filled out on-line and can be done at any time. It will require at most 10 minutes.
If interested in partecipating, please follow the link below and register in the Google Form.

After filling in the form, in a few days you will receive the survey, that contains some questions about apps that you developed.

We remain at your disposal should you need clarifications or assistance.

We thank you for your cooperation.
