Answer 1

I've responded to your previous post about the same matter

this time you place the permissions over uses sdk...

check my other answer.

Also check the ouput of LogCat. Does your application force closes?

Answer 2

Make sure you call

  <uses-permission android:name="android.permission.VIBRATE" />

In your manifest

EDIT:

Try putting your permission at the end of the manifest, or after version code.

Answer 3

may be 50 ms is too short to feel vibrate try more than 50ms
