alarmmanager

In my application i am trying to set reminder and alarm on that reminder but i am not able to do so. As i don't have complete and proper knowledge of how to set reminder, edit it and delete it. As i searched on google and what i got is not easy to understand for me. I tried a code as: Main.java Calendar cal = Calendar.getInstance(); java.util.Calendar; // add minutes to the calendar object cal.set(Calendar.MONTH, 4); cal.set(Calendar.YEAR, 2011); cal.set(Calendar.DAY_OF_MONTH, 5); cal.set(Calendar.HOUR_OF_DAY, 21); cal.set(Calendar.MINUTE, 43); Intent alarmintent = new Intent

I'm a C++ developer and developing my first Android application. My application is an special kind of Reminder. I'm looking for the best way to do it. I have tried this approaches: Use a Service Use an AlarmManager My question is that can I use AlarmManager singly? Is it a CPU time consuming task considering that my AlarmManager should be fired every 1 second ? (It seems that every time an AlarmManager is executed a new process except main process is created and immediately is killed). If I use a service then my application should always stay in memory and also what happens if is killed by

I have set an alarm at specific time. If the phone is turn off the alarm is lost? I have turn off the phone, start it again but the alarm did not trigger at the specified time. PendingIntent pendingIntent = PendingIntent.getBroadcast( Global.a.getApplicationContext(), (int) cd.e.alarmTime, intent, 0); AlarmManager alarmManager = (AlarmManager) Global.a.getSystemService(Activity.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC, cd.e.alarmTime, pendingIntent); First you need to create a BroadcastReceiver to trigger on BOOT_COMPLETE public class BootReceiver extends BroadcastReceiver { @Override

I've set up a Preference Screen in which i have a list preference which allows user to select time interval to notify them. They can choose whether to notify them after every 2,4,8,10 or 12 hours. Here's my list preference: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" > <ListPreference android:title="Notification Timer" android:summary="Select when to Notify" android:dialogTitle="Show Notification after every:" android:positiveButtonText="OK" android:negativeButtonText="Cancel" android:entries="@array/entries" android

I'm trying to create an alarm based application. I'm using AlarmManager . The thing is that it's not reliable at all. In some devices it works.. in other devices it works somethimes.. and in other devices it doesn't work at all. When I say that it doesn't work is that simply, alarms won't fire. For example, in my Xiaomi Mi4, if you turn off the screen, no alarm will fire. I have a testing Moto G and in that phone alarms use to work fine, but in OnePlus, alarms won't fire too. They simply are never called. Am I missing something? Does anybody know what am I doing wrong?? Thanks a lot for your

I'm using alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME, 0, DURATION, broadcast); To schedule an repeating task that should only be executed if the device is not asleep. As I understand the API on the AlarmManager the intent will be called once the device wakes up from sleep. Now when is an Android device asleep? For testing I set the duration to two minutes and connected the device to my machine. Now I'm watching logcat and every two minutes it will spit out my debug message. I always thought that an deactivated screen means that the devices starts sleeping. Or is my looking
