I am working on alarmmanager. Alarmmanager fires on time which i set.But the problem is when system or user destroy the application, alarmmanager fires again. It fires only if user once set-up the alarmmanager.I mean after reboot if user open application and close without set alarm, it doesnt fire on destroy.
But after set up, it fires on all destroys.
Here is my code:
Manifest
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity

android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity

android:label="@string/title_activity_time_picker" >

MyAlarmreceiver

//Bu receiver MainActivity de tanımladığımız alarm manager broadcast yaptığında bu sinyali yakalayıp MyAlarmService servisini
//çalıştırır.MyAlarmService manifestte servis olarak tanımlanmıştır.
//Myreciever de manifesto da reciever olarak tanımlanmıştır.

MyAlarmService (it fires notification)
public class MyAlarmService extends Service {
//private NotificationManager mManager;
public IBinder onBind(Intent arg0){
return null;
}
public void onCreate(){

}
public void onStart(Intent intent, int startId){
super.onStart(intent, startId);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
long[] pattern = {500,500,500,500,500,500,500,500,500};
NotificationManager nm = (NotificationManager) getApplicationContext().getSystemService(NOTIFICATION_SERVICE);
//Yeni bir pendingIntent açıyoruz ve içerisine de yeni bir intent oluşturuyoruz
PendingIntent pi = PendingIntent.getActivity(MyAlarmService.this, 0, new Intent(MyAlarmService.this, MainActivity.class), 0);
//Ardından notification adında bir notification yani bildirim oluşturuyoruz ve bilgilerini giriyoruz.
Notification notification =new Notification.Builder(MyAlarmService.this)
.setContentIntent(pi) // bildirime tıklayınca açılacak olan pendingintent
.setContentTitle("Bildirim Ornegi")
.setContentText("Bildirimin içindeki text")
.setSmallIcon(R.mipmap.ic_launcher)
.setAutoCancel(true) // Bildirime tıklayınca bildirim yok olsun.
.setSound(alarmSound)
.setVibrate(pattern)
.setLights(Color.BLUE,500,500)
.addAction(R.mipmap.ic_launcher, "bildirimin en alt mesajı", pi) // bildirimi açınca altta bişeyler daha çıkarıyor.
.build(); //Butun yukarda girilen özellikleri combine edip yeni notification objesi oluştur.
nm.notify(1, notification);
Can anyone help ?
