I'm using Timer() due to its accuracy but works in the same was as PostDelayed Handler. It's called only once. Here is the Timer code:
public void setWFT() {
WFT = new Timer();
WFT.schedule(new TimerTask() {
@Override
public void run() {
WFTTimerMethod();
}
}, 60000); // 60 seconds delay
}
private void WFTTimerMethod() {
this.runOnUiThread(Timer_Tick);
}
private Runnable Timer_Tick = new Runnable() {
public void run() {
// My commands here
}
};
This only calls run() once after 60 seconds once the Timer is started. Sometimes, I have to cancel the Timer to Update the delay (replace the "60000" value). To start the Timer again, I simply recreate the Timer by calling WFT() again with the new delay value.
Problem is, when I cancel the timer using:
WFT.cancel();
WFT.purge();
The Timer does not start. the run() doesn't execute when it's supposed to. So my question is do I use cancel() and purge() or just cancel()?
Thanks
From the Java API on purge()
:
Most programs will have no need to call this method. It is designed for use by the rare application that cancels a large number of tasks. Calling this method trades time for space: the runtime of the method may be proportional to n + c log n, where n is the number of tasks in the queue and c is the number of cancelled tasks.
So you only need to call cancel()
from cancel()
documentation :
No more tasks may be scheduled on this Timer.
