A user can download the android app from any where - Google play, Amazon app store, Opera app store, Samsung app store..

Some of the android apps can also be ported into other OS providing access to android apps, like Kindle Fire OS, Blackberry OS, Nokia X.

Do install numbers seen in Google play developer statistics include installs from other app stores like amazon, opera, Samsung etc.,?

How about android apps that can be installed non-android devices as stated above?

This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "Questions about writing and publishing Android apps, writing custom ROMs, and other topics that are primarily of concern to developers are off-topic. Consider taking advantage of other resources that may be appropriate for your question." – Chahk, onik
If this question can be reworded to fit the rules in the help center, please edit the question.

  • You will have to ask Google how they compute the statistics. Overall, this question is off-topic here because it is about publishing of apps. – Chahk Mar 13 '14 at 13:10

The app stores you mention are different from each other. So, they maintain separate / different statistics.
