hookshy Well-Known Member Licensed User Longtime User Sep 9, 2013 #1 I am using a timer to show every 300 ms a diferent bitmap image inside of a imageview depending on some values that read from a file . What happens if the time to process the code inside timer_click sub requires more than 300 ms ?(searching big array of data, in my case I use exccesive substring2 function). I noticed that my battery got low very fast though i was downloaded the source text every 15 seconds with http.util . When using timers do you have to wory about the time the timer ticks in order to let the processor handle the code inside?

Click to expand... No. The next tick event will only fire x milliseconds after the previous event was completed (x = Timer.Interval). Upvote 0
