NOTE: Refer Setup Android Notification. NOTE: To support multiple alarm, use a different requestCode for each alarm. Refer Android AlarmManager: Multiple Alarm With Arguments/Parameters. NOTE: AlarmManager is removed when the app is uninstalled, and it seems the Alarm is cancelled after APK update (not sure if this is true or always true). And in the manifest (under the app permissions it says 'set an alarm'): android:name='com.android.alarm.permission.SETALARM'/ android:name='com.example.checkproducts.AlarmReceiver'/ In my main I call the function checkproducts with the parameters, but whatever I try to do; it doesn't show anything.

This example demonstrate about How to set an Android notification to a specific date in the future.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
Step 3 − Add the following code to src/MainActivity.
Step 4 − Add the following code to src/MyNotificationPublisher.
Step 5 − Add the following code to AndroidManifest.xml
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −

This example is suited for repeating alarm at certain interval (e.g. hourly, daily, etc) but doesn’t gurantee accuracy of repeating time (e.g. 9am daily). Refer to Caveats of Repeating Alarm.
Usage
NOTES:
PendingIntent.FLAG_CANCEL_CURRENT
to make sure only 1 alarm is created/overwritten no matter how many timesstartAlarm
is called- setInexactRepeating: The alarm’s first trigger will not be before the requested time, but it might not occur for almost a full interval after that time. In addition, while the overall period of the repeating alarm will be as requested, the time between any two successive firings of the alarm may vary.
triggerAtMillis
indicate when is the first time it should triggered. If the time has passed, it might trigger immediately.triggerAtMillis
is in GMT/UTC
Caveats of Repeating Alarm
If an alarm is delayed (by system sleep, for example, for non
_WAKEUP
alarm types), a skipped repeat will be delivered as soon as possible. After that, future alarms will be delivered according to the original schedule; they do not drift over time. For example, if you have set a recurring alarm for the top of every hour but the phone was asleep from 7:45 until 8:45, an alarm will be sent as soon as the phone awakens, then the next alarm will be sent at 9:00.As of API 19, all repeating alarms are inexact. Because this method has been available since API 3, your application can safely call it and be assured that it will get similar behavior on both current and older versions of Android.
Your alarm’s first trigger will not be before the requested time, but it might not occur for almost a full interval after that time. In addition, while the overall period of the repeating alarm will be as requested, the time between any two successive firings of the alarm may vary. If your application demands very low jitter, use one-shot alarms with an appropriate window instead; see setWindow(int, long, long, android.app.PendingIntent) and setExact(int, long, android.app.PendingIntent).
It seems as of
API 19 (Android 4.4 - KitKat)
, calling setRepeating
is same as setInexactRepeating
. It is suitable for job that repeats within a certain interval (hourly, daily, etc.), but doesn’t need to execute at the exact time (e.g. 9am every day). I believe the repeating alarm will drift (as setRepeating
behaviour is inexact as of API 19), as in the following sequence might occur- Day 1: 9am
- Day 2: 9.05am
- Day 3: 9.30am
- Day 4: 10am
- Day 5: 10am
- Day 6: 11.30am

Android Alarm Manager Example
If you need to repeat at specific time daily (e.g. 9am every day), use setExact or setWindow (allow slight delay as per the window specified, but more energy efficient). If you need extreme accuracy (e.g. Alarm Clock) and execute even though the system is in low-power idle modes, use setExactAndAllowWhileIdle.
You have to program the repetition part yourself, set the next alarm again after the current alarm is triggered at
onReceive
.Refer to Daily Repeating Alarm/Reminder at Specific Time With AlarmManager.
