I would have probably seen that if the "operation" indicated by the
"pendingintent" is used as a key.
But I am saying an explicit "removal" of the alarm containing the
"operation" (pending intent).
See the code (little) below.
Moreover what one is doing is
alarms.put("at 11pm", foo)
alarms.put("at 12 pm", foo)
Conceptually I would have understood if I did
pendingintent.gooff("at 11");
pendingintent.gooff("at 12");
*** AlarmManagerService.java extract
160 public void setRepeating(int type, long triggerAtTime, long interval,
161 PendingIntent operation) {
162 if (operation == null) {
163 Slog.w(TAG, "set/setRepeating ignored because there
is no intent");
164 return;
165 }
166 synchronized (mLock) {
167 Alarm alarm = new Alarm();
168 alarm.type = type;
169 alarm.when = triggerAtTime;
170 alarm.repeatInterval = interval;
171 alarm.operation = operation;
172
173 // Remove this alarm if already scheduled.
174 removeLocked(operation);
175
176 if (localLOGV) Slog.v(TAG, "set: " + alarm);
177
178 int index = addAlarmLocked(alarm);
179 if (index == 0) {
180 setLocked(alarm);
181 }
182 }
183 }
AlarmManagerService doest maintain separate 'alarm' objects with every
"set" even with the same equivalent intent. It then physically removes
one of the alarm objects that were scheduled earlier.
Is this to avoid a later confusion between two alarms with the same intent??
Anyway thanks for chiming in
