Android AlarmManager fails to work -


according knowledge, should see log "alarm" in logcat after 20 seconds starting application, not happening. missing?

public class mainactivity extends activity { private pendingintent pendingintent; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); intent intent = new intent(mainactivity.this, mainactivity.class); pendingintent = pendingintent.getservice(mainactivity.this, 1, intent, 1); alarmmanager manager = (alarmmanager) getsystemservice(context.alarm_service); manager.set(alarmmanager.rtc_wakeup, system.currenttimemillis() + 20000, pendingintent); log.d("alarm", "alarm"); } }

seems should use

getactivity (context context, int requestcode, intent intent, int flags)

as intent specifies activity class, not service. next, last parameter (flags) can have values constants in pendingintent class. , mentioned, second paramter should 0 not used currently. please refer this question sample usage.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
