[android-developers] Re: Is runOnUiThread() ever 'safe' to call? If not why is it not deprecated?

[Doug]

There's a difference between "promoting" and "showing a simple, terse 
example".  This I think is the latter.  I'm pretty sure if you ask any of 
the on-staff developer advocates if you should be writing 
production-quality code like this, they will probably say no, using a 
better mechanism.  But this is short and to the point.  The best 
production-worthy example would, unfortunately, take at least twice as many 
lines of code.

Also, this particular BT API is deprecated.

[android-developers] Control Android Wear Vibrations

[Saurav]

Hey All,

It has been wrong and I have made a point to work everyday for a small
amount of time on something I love, Android.

Could someone please point me to APIs or materials that would help me
CONTROL the vibration on my Android Wear.

Thanks in advance!

Regards,
Saurav Mukherjee
