Does anyone have a suggestion of any jewish Android Apps such as a calendar (halachic times and dates), siddur, sefarim, kashrut/ ask a rabbi, learn Hebrew/Yiddish/ladino etc..., and jewish music apps?
OnYourWay (Uvelechtecha Baderech) contains a large number of Torah texts for free. It was originally made for the iPhone, but is now available on Android also (though its interface is a bit more difficult to use).

There's an app called JStream that let's you stream Jewish music from various stations. JStream
Or for that matter, just search for Jewish on the market...
Orayta Jewish Books has what seems to be a phenomenal set of Jewish books in its app. I don't have it myself, but I'm very tempted to not only download it, but to donate to the developers as well.
If I may toot my own horn, I have an app, "Real Clear Daf," which is packed with features to facilitate your Gemara learning (e.g. dictionary, blog, note-taking, audio shiur, etc.).
It's available for both Android and Apple and it's absolutely FREE!
