I have a few questions: What is the package that I can use to access the number of notifications that came from my phone (like SMSs, Facebook, etc)? I'm using 3.2.0+

I have a few questions:

1. What is the package that I can use to access the number of notifications that came from my phone (like SMSs, Facebook, etc)? I'm using 3.2.0+

2. Also, where can I find the minimum APIs available for each watch. For example, I have a Venu 2... what is the lowest version that the watch is shipped with?

3. Does the simulator always have a heartbeat of 80, except during an activity?

Any help would  be appreciated, Thanks.
