Is there a way to evaluate Android apps in a browser (like Pieceable for Android)? I have seen Pieceable which is a Website where you can upload iOS apps and then try them out directly in the browser. Is something like this also available for Android?

To upload an APK File, embed some code into a website and be able to try out the app before buying it?
Thanks for introducing Pieceable. After reading your question I learnt about it and when going beyond, I found Amazon's Test Drive seems to have a similar ability.  Thanks to @jcisio, I found this answer here.  Currently the Amazon Test drive is available in US only. Hence, I could not test and verify it.
