Question

So I have indeed searched thoroughly for an answer to my question; normally I can find answers pretty easily to pretty much anything.

Anyway, basically I have an alarm manager set up which eventually sets a broadcast receiver. Inside the receiver, it decides which intent has been received, removes a shared preference, and then sets a notification that starts the activity. The problem is that on my phones with 4.0 the shared preference item is not successfully deleted, but on any previous phones I’ve tried (2.2, 2.3) it works perfectly.

I did end up finding the documentation of Android 3.1 and the FLAG_INCLUDE_STOPPED_PACKAGES implementation. I tried throwing that onto the intent, just in case, but it still wasn’t working. Either way, it’s not the launching of the activity that is the problem, but the simple deletion of a shared preference.

I hope that’s clear enough! I’ll put in some of the code below.

This is where the intent is started:

Calendar cal = Calendar.getInstance();
int seconds = 5 * 60; // 1 * 24 * 60 * 60;
cal.add(Calendar.SECOND, seconds);

Intent intent = new Intent(SetAlertActivity.this, ReminderReceiver.class);
intent.putExtra("id", "FAlert");
//intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), FRAUD_ALERT_CODE, intent, 0);

AlarmManager alertManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alertManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

settingsEditor = alertSettings.edit();
settingsEditor.putLong("AlertTime1", cal.getTimeInMillis());
settingsEditor.commit();

And then the broadcast receiver onReceive():

    nContext = context;
    alertSettings = nContext.getSharedPreferences(MainActivity.PREFERENCE_FILENAME, 0);
    if (intent.getStringExtra("id").equals("FAlert"))
    {

        settingsEditor = alertSettings.edit();
        settingsEditor.remove("AlertTime1");
        settingsEditor.commit();

        String ns = Context.NOTIFICATION_SERVICE;
        int icon = R.drawable.ar_icon;
        CharSequence tickerText = nContext.getString(R.string.notification_ticker);
        CharSequence contentTitle = nContext.getString(R.string.notification_title);
        CharSequence contentText = nContext.getString(R.string.notification_text);
        long when = System.currentTimeMillis();

        NotificationManager mNotificationManager = (NotificationManager) nContext.getSystemService(ns);
        Notification notification = new Notification(icon, tickerText, when);

        Intent notificationIntent = new Intent(nContext, SetAlertActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(nContext, 135, notificationIntent, 0);

        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_LIGHTS;
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.setLatestEventInfo(nContext, contentTitle, contentText, contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, notification);
    }

So, as I mentioned before, on my devices on 4.0 (I don’t have any 3.X devices) the

settingsEditor = alertSettings.edit();
settingsEditor.remove("AlertTime1");
settingsEditor.commit();

part isn’t working. The activity will open correctly, but the “AlertTime1” is still there. On the 2.2 and 2.3 devices, the “AlertTime1” is successfully deleted.

sigh 😀

Thanks for any help!!

Oh, and in case it’s needed, here is my manifest for the receiver:

<receiver
    android:name="ReminderReceiver"
    android:process=":remote" >
</receiver>

This is where the difference shows:

    alertSettings = getSharedPreferences(AlertRenewActivity.PREFERENCE_FILENAME, 0);
    settingsEditor = alertSettings.edit();
    if (alertSettings.contains("AlertTime1"))
    {
        alertTime = alertSettings.getLong("AlertTime1", 0);
        timeLeft = (int) ((alertTime - System.currentTimeMillis()) / (1000L));
        daysLeft = timeLeft / (60 * 60 * 24);
        daysLeftView.setText(Integer.toString(daysLeft));
        setAlert.setEnabled(false);
        setAlert.setTextColor(R.color.dark_text);
    }
    else
    {
        daysLeftView.setText(R.string.no_alert_set);
    }

On my older phones, it correctly resets to saying “No Alert Set” but on the 4.0 phones it still shows “0” days left (which is what it says since I’m only setting the alert to 5 minutes or so for testing). Basically, the user can’t set a new alert because it hasn’t reset correctly, and again, only on the 4.0 phones I’m trying 😛

Answer 1

What I ended up doing was just having a check in the activity itself that says “if the alarm time is less than 0, delete the alarm time.” It was a work around; I didn’t receive any other answer that worked unfortunately.
