LocalNotification with AlarmManager and BroadcastReceiver not firing up in Android O (oreo)
Solution 1:
Android O are pretty new to-date. Hence, I try to digest and provide as accurate possible information.
From https://developer.android.com/about/versions/oreo/background.html#broadcasts
- Apps that target Android 8.0 or higher can no longer register broadcast receivers for implicit broadcasts in their manifest.
- Apps can use
Context.registerReceiver()at runtime to register a receiver for any broadcast, whether implicit or explicit.
- Apps can use
- Apps can continue to register explicit broadcasts in their manifest.
Also, in https://developer.android.com/training/scheduling/alarms.html , the examples are using explicit broadcast, and doesn't mention anything special regarding Android O.
May I suggest you try out explicit broadcast as follow?
public static void startAlarmBroadcastReceiver(Context context, long delay) {
Intent _intent = new Intent(context, AlarmBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, _intent, 0);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
// Remove any previous pending intent.
alarmManager.cancel(pendingIntent);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + delay, pendingIntent);
}
AlarmBroadcastReceiver
public class AlarmBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
}
}
In AndroidManifest, just define the class as
<receiver android:name="org.yccheok.AlarmBroadcastReceiver" >
</receiver>
Solution 2:
Today i had the same problem and my notification was not working. I thought Alarm manager is not working in Oreo but the issue was with Notification. In Oreo we need to add Channel id. Please have a look into my new code:
int notifyID = 1;
String CHANNEL_ID = "your_name";// The id of the channel.
CharSequence name = getString(R.string.channel_name);// The user-visible name of the channel.
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);
// Create a notification and set the notification channel.
Notification notification = new Notification.Builder(HomeActivity.this)
.setContentTitle("Your title")
.setContentText("Your message")
.setSmallIcon(R.drawable.notification)
.setChannelId(CHANNEL_ID)
.build();
Check this solution. It worked like charm.

I am showing my method:
public static void pendingListNotification(Context context, String totalCount) {
String CHANNEL_ID = "your_name";// The id of the channel.
CharSequence name = context.getResources().getString(R.string.app_name);// The user-visible name of the channel.
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationCompat.Builder mBuilder;
Intent notificationIntent = new Intent(context, HomeActivity.class);
Bundle bundle = new Bundle();
bundle.putString(AppConstant.PENDING_NOTIFICATION, AppConstant.TRUE);//PENDING_NOTIFICATION TRUE
notificationIntent.putExtras(bundle);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= 26) {
NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);
mNotificationManager.createNotificationChannel(mChannel);
mBuilder = new NotificationCompat.Builder(context)
// .setContentText("4")
.setSmallIcon(R.mipmap.logo)
.setPriority(Notification.PRIORITY_HIGH)
.setLights(Color.RED, 300, 300)
.setChannelId(CHANNEL_ID)
.setContentTitle(context.getResources().getString(R.string.yankee));
} else {
mBuilder = new NotificationCompat.Builder(context)
// .setContentText("4")
.setSmallIcon(R.mipmap.logo)
.setPriority(Notification.PRIORITY_HIGH)
.setLights(Color.RED, 300, 300)
.setContentTitle(context.getResources().getString(R.string.yankee));
}
mBuilder.setContentIntent(contentIntent);
int defaults = 0;
defaults = defaults | Notification.DEFAULT_LIGHTS;
defaults = defaults | Notification.DEFAULT_VIBRATE;
defaults = defaults | Notification.DEFAULT_SOUND;
mBuilder.setDefaults(defaults);
mBuilder.setContentText(context.getResources().getString(R.string.you_have) + " " + totalCount + " " + context.getResources().getString(R.string.new_pending_delivery));//You have new pending delivery.
mBuilder.setAutoCancel(true);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
Solution 3:
Create the AlarmManager by defining an explicit intent (explicitly define the class name of the broadcast receiver):
private static PendingIntent getReminderReceiverIntent(Context context) {
Intent intent = new Intent("your_package_name.ReminderReceiver");
// create an explicit intent by defining a class
intent.setClass(context, ReminderReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
return pendingIntent;
}
Also do not forget to create a notification channel for Android Oreo (API 26) when creating the actual notification:
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (VERSION.SDK_INT >= VERSION_CODES.O) {
notificationManager.createNotificationChannel(NotificationFactory.createNotificationChannel(context));
} else {
notificationManager.notify(NotificationsHelper.NOTIFICATION_ID_REMINDER, notificationBuilder.build());
}
Solution 4:
try this code for android O 8.1
Intent nIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
nIntent.addCategory("android.intent.category.DEFAULT");
nIntent.putExtra("message", "test");
nIntent.setClass(this, AlarmReceiver.class);
PendingIntent broadcast = PendingIntent.getBroadcast(getAppContext(), 100, nIntent, PendingIntent.FLAG_UPDATE_CURRENT);
