Android Alarm Manager with broadcast receiver registered in code rather than manifest

Question

I want to use an alarm to run some code at a certain time. I have successfully implemented an alarm with the broadcast receiver registered in the manifest but the way i unde

Answer 1

How about this?

Intent startIntent = new Intent("WhatEverYouWant");
PendingIntent startPIntent = PendingIntent.getBroadcast(context, 0, startIntent, 0);
AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, triggerTime, startPIntent);

And then in your Manifest.xml file:

<receiver android:name="com.package.YourOnReceiver">
   <intent-filter>
       <action android:name="WhatEverYouWant" />
   </intent-filter>
</receiver>

So as far as I know you still have to declare the receiver in the Manifest. I'm not sure if you can set it to a private instance inside of your activity. You could declare an onReceive inside of your activity and call that (if the BroadcastReceiver has an interface. I don't know if it does.)

Start a alarm intent from where you want to start alarm. write below code from where you want to start to listen the alarm

Intent myIntent = new Intent(getBaseContext(), **AlarmReceiver**.class);
                PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), 0, myIntent, 0);
                AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
                Calendar calendar = Calendar.getInstance();
                calendar.setTimeInMillis(System.currentTimeMillis());
                calendar.add(Calendar.MINUTE, shpref.getInt("timeoutint", 30));
                alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

And in broadcast receiver write the code you want to receive. And in menifest write below

<receiver android:name=".AlarmReceiver" android:process=":remote"/>

You can also put repetitive alarm also. Hope it help!
