Persistent Alarm

I am trying to setup an alarm that will remain on because I want it to go off 3 days from now and I know Android will kill my app before that.

In my Activity

private void setAlarm() {
    //ContactAlarmReceiver contactAlarmReceiver = new ContactAlarmReceiver();
    //contactAlarmReceiver.setAlarm(getApplicationContext(), dateInMillis, phonenumberET.getText().toString(), firstnameET.getText().toString());
    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent alarmIntent = new Intent(MyConstants.BROADCAST_ACTION_CONTACT_ALARM);
    alarmIntent.putExtra("phone", phonenumberET.getText().toString());
    alarmIntent.putExtra("name", firstnameET.getText().toString());

    PendingIntent pi = PendingIntent.getBroadcast(this, 0, alarmIntent, 0);
    //am.setAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, timeInMills, pi);
    if (Build.VERSION.SDK_INT >= 23) {
        am.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, dateInMillis, pi);
    } else if (Build.VERSION.SDK_INT >= 19) {
        am.setExact(AlarmManager.RTC_WAKEUP, dateInMillis, pi);
    } else {
        am.set(AlarmManager.RTC_WAKEUP, dateInMillis, pi);
    }
    ComponentName component = new ComponentName(this, ContactAlarmReceiver.class);
    getPackageManager()
        .setComponentEnabledSetting(component,
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);
}

Manifest:

<receiver
    android:name=".ContactAlarmReceiver"
    android:enabled="false">
    <intent-filter>
        <action android:name="com.example.johnbravado.CONTACTALARM" />
        <action android:name="com.example.johnbravado.NOTIFLTBTN" />
        <action android:name="com.example.johnbravado.NOTIFRTBTN" />
    </intent-filter>
</receiver>

ContactAlarmReceiver:

@Override
@Override
public void onReceive(Context context, Intent intent) {
    PowerManager powerManager = (PowerManager) context.getSystemService(POWER_SERVICE);
    PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
            "com.example.johnbravado.zionwork");
    wakeLock.acquire();

    final NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    Bundle extras = intent.getExtras();
    ComponentName receiver = new ComponentName(context, ContactAlarmReceiver.class);
    PackageManager pm = context.getPackageManager();

    if (intent.getAction().equals(MyConstants.BROADCAST_ACTION_CONTACT_ALARM)) {
        int count = extras.size();
        String num = extras.getString("phone");
        String name = extras.getString("name");
        sendContactNotification(context, MyConstants.BIG_NOTIFICATION_ID, num, name);
    }

    if (intent.getAction().equals(MyConstants.BROADCAST_ACTION_NOTIF_LTBTN)) {
        sendSMS(context, extras.getString("phone"), extras.getString("msg"));
        mNotificationManager.cancel(MyConstants.BIG_NOTIFICATION_ID);
        pm.setComponentEnabledSetting(receiver,
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                PackageManager.DONT_KILL_APP);
    }

    if (intent.getAction().equals(MyConstants.BROADCAST_ACTION_NOTIF_RTBTN)) {
        initiatePhone(context, intent.getExtras().getString("phone"));
        mNotificationManager.cancel(MyConstants.BIG_NOTIFICATION_ID);
        pm.setComponentEnabledSetting(receiver,
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                PackageManager.DONT_KILL_APP);
    }
    wakeLock.release();
}

I never receive the notification after long periods of time. For example, I set the alarm at 11pm for 3am, so when i wake up i should see the notification. But there is no notification displayed.

I would like to suggest You that, first of all create a class like:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if(intent.getAction().equals("startalarm")){
        intent = new Intent(context, Your_service.class);
        context.startService(intent);

}

    }
}

Note: If your alarm has to perform network task, then start a download service inside onRecieve() method of your alarm broadcast. Then,set AlarmReceiverclass in Intent.

Intent alarmIntent = new Intent(MyActivity.this, AlarmReceiver.class);

perhaps you will get out from your problem.
