You don’t need to create Timestamps. You can do it with your Calendar. Calendar calendar = Calendar.getInstance(); calendar.set(Calendar.HOUR_OF_DAY, hourOfDay); calendar.set(Calendar.MINUTE, minute); if(calendar.before(Calendar.getInstance())) { calendar.add(Calendar.DATE, 1); } alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingDinnerIntent); I would also mention that as of KitKat, if your targetSdkVersion is 19 or above, the AlarmManager#set() method is not exact.

Here is a snippet showing the setup of AlarmManager: AlarmManager mgr=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent i=new Intent(context, OnAlarmReceiver.class); PendingIntent pi=PendingIntent.getBroadcast(context, 0, i, 0); mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), PERIOD, pi); In this example, I am using setRepeating(). If you want a one-shot alarm, you would just use set(). Be … Read more
This is working code. It wakes CPU every 10 minutes until the phone turns off. Add to Manifest.xml: … <uses-permission android:name=”android.permission.WAKE_LOCK”></uses-permission> … <receiver android:process=”:remote” android:name=”.Alarm”></receiver> … Code in your class: package yourPackage; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.PowerManager; import android.widget.Toast; public class Alarm extends BroadcastReceiver { @Override public void … Read more
