Phone Vibrations do not occur when interacting with UI

Hey all, trying to make phone vibrate on a certain condition and it works fine, however, if I am currently interacting with the phone, typing, or changing apps or screens, the vibrations do not occur. If it is a three pulse vibration, then if after one pulse i stop using UI, then two pulses occur. I guess they both need eventThread and UI takes precedence? How could I get it to still vibrate even if using UI. If necessary I can make screen freeze while vibrating as the vibration is the most important but I know you can still vibrate and type when you get a text, etc.


My code for the vibrations is: 


if (repeat != false) {
							new Runnable() {
								public void run() {
									for (int x = 0; x < savedList.size(); x++) {
										if (devicesListAddress
														.elementAt(x)) == false
												&& watchList
																.elementAt(x)) == false) {
											for (int b = 0; b < vibratelength; b++) {
												try {
													if (b != vibratelength)
												} catch (InterruptedException e) {


 That is all that is relevant, it is not closed properly, that occurs later on. I use a new Runnable which is invokedLater, is this the proper way to trigger this event? Is there an alternative that could fix this? 


Thanks as always guys!

Re: Phone Vibrations do not occur when interacting with UI

format your code properly please.

do not use thread.sleep on the ui thread, it blocks it.
you can use a separate thread or a timertask.
