Android cancel Toast when exiting the app and when toast is being shown

Question

I have read about this kind of problem here but the answers don\'t seem to be working.

I show a Toast when user clicks a button. When the user continous

Answer 1

Try keeping the timestamp of the last toast, and don't allow any new toasts until a timeout period has elapsed.

Something like:

private static final long TOAST_TIMEOUT_MS = 2000; // tweak this constant

private static long lastToastTime = 0;

public void onButtonClicked() {
  long now = System.currentTimeMillis();
  if (lastToastTime + TOAST_TIMEOUT_MS < now) {
    Toast.makeText(...).show();
    lastToastTime = now;
  }
}

I wouldn't worry about a single toast sticking around for a second after the user exits the app -- this is a pretty standard behavior.
