E-mails of users which send comments to android market? How to get them?

Many of users complain about my products, however they do it without any details. For instance they only write, that crash occur on start, however I can reproduce it, because I don't know which device was used by user.

It w开发者_开发技巧ill be great if I could send an e-mail, to specific users and ask about details.

Is there any way to send user private message or something?

Not yet. Roman Nurik told us on Google Developers Day'2010 that it is planned, but they simply lack resources to implement all this features. Just wait.

I can advice you to add some contact info in your application to let users contact you dorectly.

No way to contact users directly. However you could use ACRA to get more info about crashes

This isn't a technical solution, but I have found that users of my apps have responded well to me just adding a note in the app description that I would really like them to e-mail me if they have any problems so that I can attempt to resolve the issue.
