Notifications Not Shown - Mobile Button

Mutual reasons why Mobile Push button notifications are not showing on your device.

"Delivered" notifications in OneSignal means we have successfully sent the notification to the button servers (FCM/APNS/WNS etc..). These button servers then distribute the notifications to your subscribers. The "Confirmed" stat means our SDK received the notification which should have been shown on the device. See Confirmed Deliveries for more details.

The following are reasons why notifications may show as "Delivered" on the OneSignal dashboard or API, only are non visible on your device.

Devices must exist online to receive push notifications. If your device is turned off, in airplane way, has unstable or no internet connectedness, the push volition not show until a proper connexion is fabricated. You can set the timeframe Google and Apple tree Servers will await for a connection with the Time To Live (TTL) Parameter (the default is 3 days).

Cheque the network / WiFi you lot're connected as it may have closed your connection to Apple tree or Google servers'. Attempt disabling and re-enabling your internet connectedness. Also try without wifi using cellular data.

If yous are restricting traffic to or from the Internet, you need to configure information technology to allow connectivity with FCM which requires open ports to: 5228, 5229, and 5230. More than details: https://firebase.google.com/docs/cloud-messaging/concept-options

APNS devices must connect to: TCP port 5223 & TCP port 443 or 2197. More than details: https://support.apple.com/en-usa/HT203609

If you bank check the logs from the app, yous may also see:

              ERROR: Encountered error during push registration with OneSignal:  Mistake Domain=OneSignalError Lawmaking=0 "(null)" UserInfo={error=Error Domain=NSURLErrorDomain Code=-1004  "Could not connect to the server."  UserInfo={NSUnderlyingError=0x2834051a0 {Mistake Domain=kCFErrorDomainCFNetwork Code=-1004 "(cypher)"  UserInfo={_kCFStreamErrorCodeKey=61, _kCFStreamErrorDomainKey=1}}, NSErrorFailingURLStringKey=https://api.onesignal.com/players, NSErrorFailingURLKey=https://api.onesignal.com/players, _kCFStreamErrorDomainKey=one, _kCFStreamErrorCodeKey=61,  NSLocalizedDescription=Could not connect to the server.}}

  1. Cheque the segment you lot sent the push to and make certain it is setup correctly. This is under Segments. Sometimes an incorrect filter is added to the segment removing sure devices.

  2. Check the Thespian ID record in the Audience > All Users department of the dashboard. Nether the "Segments" column, you will see if that user is in the segment targeted for push button.

Android,iOS: In your Device Settings > Notifications > Your App, y'all tin can turn on and off push notifications.

Make sure push button permissions are enabled for your device:

Android Settings App > Notifications > Your App you should see "Prove notifications" enable and all categories underneath enabled. If yous have a category disabled, you will not get notifications from that category.

In this example, the "Abandoned Cart - Urgent" Category is turned off. If I set this category in the notification, the device volition not get this notification.

If no category is set, OneSignal uses a default "Miscellaneous" category. Make sure that is enabled if not setting categories. See Android Notification Categories for more than details.

Keep the app running, but put information technology in the groundwork/out of focus when testing.

If your app is open while sending, you lot may be hiding the notification using the Foreground Notification Received Event if on our updated Major release SDK or In-Focus Displaying is fix to None or 0 if on an older version of OneSignal SDK.

Some devices have a specific battery optimization that volition stop or subtract rate of notifications showing.

Android: In Settings, search for:

  • Power Saving Way or Energy Saving - If "Ability Saving Fashion" and/or "Limit apps and Dwelling house Screen" is enabled, this will limit all background activity (push notifications) from being received.
  • Adaptive power saving mode - If enabled, device will automatically plow on/off "Power Saving Mode" based on your usage patterns.
  • or Bombardment Optimization or Background usage limits - Bombardment optimized apps will have background functions (like push button notifications) restricted. Brand certain your app is Non Optimized.

iOS: If the device has Low Ability Mode enabled and has low power, it volition reduce the rate at which notifications tin be received. Bank check if enabled in Settings > Battery > Depression Power Mode.

If Exercise Not Disturb is enabled, this prevents the notifications from "popping up" on the screen just still shows in the "Notification Middle".

iOS: Disable within in Settings > Do Not Disturb.

Android: Disable within in Settings > Notifications > Do Not Disturb. Or search for "Do non Disturb" in Settings and disable.

When an app is in a Force Stopped / Force Killed country well-nigh events including FCM messages for push notifications will not be received. An app can exist placed in this state in the following ways.

  • From Settings > Apps, "Force End" is pressed.
  • Long pressing the back push button on some devices.
  • Using a third political party task killer like Greenify.
  • Swiping away your app while remote debugging it. (Not the same as viewing the logcat merely launching your app as a remote debug process.)
  • Automatically on some devices due to custom Android tweaks washed past manufactures. This is a known result affecting all button providers (not merely OneSignal). Nosotros have written a blog post about this and provide more details and word in this Github Result.

Based on your device manufacturer, yous tin follow these steps to enable push for your device. For your app users, if you desire to help educate them on this issue, you can send these specific devices In-App Messaging to enable proper settings.

More information on problematic devices can exist found in our blog post: Notifications are highly reliable, except when device manufacturers interfere

1. Run the following to bank check the electric current land of your app.
Supplant "com.company.appname" with your package name. 

              adb vanquish dumpsys parcel com.company.appname | grep stopped

If yous encounter stopped=false if everything is fine, otherwise you lot will see stopped=true then your app was force killed in some way.

ii. Another mode is to send a few notifications and cheque for the following GCM logcat entry.

              Westward/GCM-DMM: broadcast intent callback: effect=CANCELLED forIntent {    deed=com.google.android.c2dm.intent.RECEIVE pkg=com.onesignal.example (has extras) }

If yous seen this cancelled intent higher up then your app could not exist started to process the notification.

Some device manufactures will white listing apps from going into the force airtight state. Case such equally Gmail and Whatsapp.

FCM provides a REST API to query the terminal time a device has been connected to FCM. See the post-obit Google documentation on how to go this.
https://developers.google.com/instance-id/reference/server#get_information_about_app_instances

The almost common reason is an outdated version of the OneSignal SDK in the app. Brand sure you updated to the latest version of the OneSignal SDK in your app. You should have minimum version ii.10.i.

If you are using Xcode 11, make sure you are using the latest version of the OneSignal SDK (minimum version 2.10.i). You tin open your All Users folio and cheque the SDK VERSION column to see what version you are on. Xcode 11 made a breaking alter that affects push token registration.
