Notifications are not received on xiaomi devices. Push notifications on Android and iOS tablets: from A to Z

Every business and application company has its own lists of favorite clients and projects. We love our customers, especially those who, in addition to the finished product at the end, want to independently understand the technologies and rise to the level of a specialist. Any methods are used, but “question torture” is especially popular (any tester rests).

Technical portrait of the application being developed

We were creating a mobile application for a clothing store, whose architecture was built on a basic Activity (fragments are used to display information). The Retrofit library was used to download data from the server, and a built-in dependent SQLite database was used to store it. Loaders were selected to execute requests to the server and to fetch from the database.

To make the application interactive and allow you to exchange messages, we enabled push notifications. In this case, VK and Facebook SDK are used to implement authorization/registration through social networks and it looks like this: when a user sends a message, he sends a request with this message to our server. It generates a request with the message and data about the user to whom the message was addressed, and sends all the information to the Google server. It generates a push notification from this request and sends it to the user’s device. Our application receives this push, parses (processes) it and displays it in the chat - communication is realized.

There is a problem: when does the application start running in the background or why do push notifications only arrive after launch?

A client came to us with this question, because through experience he was faced with the following dilemma: when launched from a second device, the application works well, but how does “autoload” work then?

Let's talk. The application starts working in the background immediately after installation, and subscription to push notifications is carried out after registration in the application.

If the user does not register in it, then push notifications will not work for him.

There are other explanations to consider:

1. Push notifications work through the GCM (Google Cloud Messaging) service, so if the device does not have Google Play Services, their operation is unstable, or the manufacturer has made modifications to their operation, then push notifications will not work completely or there will be interruptions in their operation. If Google Play services are not available on your phone, you won’t even be able to register for push notifications. Of course, this can also be done “forcibly”: if, after registration, the subscription to push notifications on the server is unsuccessful, then you need to continue trying each time you log into the application until the result is successful. The reason for this situation may be problems with the operation of Google Play services - in this case, an attempt to subscribe may end in nothing.
2. The reason for incorrect functioning lies in the non-ideal working environment. We recommend to our clients for testing, and call it an ideal environment, the use of Google Nexus phones (they run “pure” Android without any changes, and the OS and services work on it ideally), stable operation of the server and Internet connection. Under such conditions, requests will be issued correctly, without errors and as quickly as possible. In this case, the application will quickly load new data, display it, and there will be no problems with incorrect display of information. In other phones (with a modified operating system - Chinese brands, Samsung, HTC, etc.) you can expect not only unstable server operation, but also limited capabilities of the application being developed (due to the systemic removal of many method-functions) - yes, push -notifications may not be provided at all.
3. Don't forget the main thing - push notifications only come if there is a stable Internet connection. If this is not the case, then the message will come as soon as the connection is restored.

Summary

• An ideal environment (flawless Internet, “clean” platform) is ideal, so warn clients about all possible errors and limitations of the application’s functionality.
• Don't be afraid of clients' questions - they will carefully look for flaws in your work and find them! Thank you and fix the bugs promptly.
• First of all, create an application for users, focus on their technical capabilities and do not create unnecessary things.

Push notifications are pop-up windows that appear on the screen of a smartphone or tablet. They show incoming information from various sources, which can be instant messengers, applications or the system of the device itself. Push notifications are available on absolutely all modern devices: be it Apple gadgets or Google tablets. That is, there are Push notifications for iOS, Android, as well as .

Setting up push notifications on devices running iOS, Android and Windows Phone operating systems

Recently, the introduction of this function into the computer operating system has become especially popular. The first was Apple with its OS X axis for Macs. This is, of course, due to the high efficiency and convenience of push notifications, which have established themselves as the first source of information arriving on a smartphone or tablet. Indeed, it would be stupid to refute such a convenient method of notification: push notifications save the device’s RAM, since they do not require constant operation of a program or application. Therefore, there will also be Internet traffic.

But besides caring so much about the user and timely notifications, push notifications can be annoying. Why do you need periodic reminders from the Twitter service that a certain user wrote: “I ate an omelette today. Was it delicious? Agree that this message does not carry any useful information load for you. It turns out that not all alerts are very useful. Of course, if you indiscriminately give access to and agree to send you notifications to programs and applications, then you will have millions of them. It’s not entirely pleasant to delete them later, because on some systems you can’t delete everything at once. This makes it necessary to know how to set up and disable push notifications. Therefore, let's figure out the correct installation of this method of presenting information.

Volume buttons do much more than just increase or decrease the volume of your device's audio. Completely new options and features have been added to this menu, which will undoubtedly be useful to any user. They allow you to switch between alert modes:

1. “Do not disturb” - all incoming reminders and messages will arrive silently;
2. “Important” - you will receive only important messages from the program list, which can be adjusted. When you turn it on, you will see a settings tab. Here you can change the operating time of the mode. Moreover, there is a special tab that allows you to configure this mode more flexibly;
3. “Everything” is the standard operation of the device.

It is worth noting that push notifications configured in this way will be much more useful. Especially convenient is the “Important” mode, where you can easily manage the list of applications to access notifications.

To fine-tune the information windows, just go to the section specially designated for this. It is located in the Settings menu of your device. In it you can, for example, remove notifications on the lock screen, open the notification option for individual programs, and change the list of blocked applications. Another very interesting feature is that in the individual application menu you can optionally select:

1. Do not show from this application, thereby completely getting rid of the program's news;
2. Or show them at the top of the list, including when only important notifications are allowed.

You can enable or disable push notifications on iOS using the Settings menu located on the Home screen. You won’t have to search for the required submenu for a long time, because in the operating system it is called “Notifications”. After you go to it, on the right you will see a list of installed programs on the device. Above some there will be the inscription “turn on”, and above others it will be written “do not turn on”. This means that in the first case, alerts and push notifications are allowed, but in the second, accordingly, they are not. Let's look at a detailed configuration example.

So, it’s on our first list. Click there and go to the alert settings page for this program:

1. The very first thing we have is the permission for notifications with the corresponding slider. If you move it, you will turn them off. Accordingly, Skype will not notify you about anything;
2. Our next item is “In the notification center”. It allows you to control the number of recent events displayed in the notification bar (that is, in the notification center);
3. Sounds. With this slider you adjust the presence of sound for notifications;
4. Badge sticker. Here you can adjust the presence of a sticker with the number of incoming events on the application icon located on the main screen;
5. The penultimate setting in this menu is on the locked screen. It is responsible for displaying an alert when the screen of a tablet or smartphone is locked;
6. Well, the last thing is the warning style on the unlocked screen. The first one with such a categorical word “No” removes all visual notifications. Banners are a line at the top of the screen. Well, and “Warnings”, which are displayed in a rectangle in the center of the screen with answer options. In fact, they are all clearly shown on the notification settings page.

Users may also have a question: why don’t push notifications arrive? In fact, there may be several reasons:

1. As in the iOS example, the program may simply not be included in the allowed list. Then you will just need to go to the same menu and, scrolling down, select the desired program from the “Do not include” category. On its page, just move the slider next to “Allow notifications”. On Android the situation is similar;
2. The second reason could be that the application requires an Internet connection for notifications to work.

Now you’ve figured out why push notifications don’t arrive on Android or iOS, and how to enable, configure, or even disable them. Now you will only receive really important messages, and annoying game notifications will no longer bother you!

Notification problem is one of the common iOS problems that you may encounter on your iPhone or iPad. You have found that notification sounds and vibrations are not working on your iPhone. You need to fix this issue so that you can know about the latest messages or news from your apps.

Don't worry if you are facing this issue while updating to iOS 10 or new iOS 11/11.1. You can try our tips below to fix this problem. Applicable to iPhone 7/6s/6/5s/4s and new iPhone X/iPhone 8.

1. Simply restart your iPhone

There is no better way to fix iOS problems than simply restarting your device. I do not believe? Give it a try.

To fix the problem of not receiving notifications on your iPhone, press the power on/off button for 2-3 seconds. When the slider appears at the top of the screen, release the Power On/Off button and slide it to the right to turn off your iPhone.

Turning off your iPhone stops all activities running in the background. Many of them are initiated by the software itself and can cause your device to malfunction.

When you turn off your iPhone and turn it on or when you reset your iPhone, it boots normally and starts again.

2. Check if your iPhone is in Quiet Mode

If your iPhone is in Silent mode, this is most likely why notifications are not coming to your iPhone. Toggle the "Mute" button on the sidebar of your iPhone and see if the orange bar appears as shown below.

If the orange bar is visible, it means your iPhone is in Silent mode, which prevents notifications from working. Simply switch the button the other way to put your iPhone in General mode and you'll get all push notifications again.

Many times, users put their iPhone in silent mode and forget about it. For all the new iPhone users, this tip will be useful, check before moving on to other solutions.

Do Not Disturb, better known as DND, is a great feature offered by iOS. With this feature, you can turn off notifications and calls if you want, except for receiving calls from selected (favorite) contacts.

However, if this feature was enabled unknowingly or by mistake, it may cause the iPhone to not receive notifications. When you see the moon icon at the top of the home screen, it means the feature is enabled.

You can turn off Do Not Disturb mode by visiting Settings > Do Not Disturb > Turn Off

Once you disable DND, push notifications will start working on your iPhone.

Also make sure that Do Not Disturb is not turned on for any specific contacts. To check this, launch the Messages app where you can see your messages. Does every message have a Moon sign? If yes, it means you have enabled do not disturb for this contact:

Turn off that, the Details tab, and turn off Do Not Disturb. Many users are not aware of this great feature. If you are one of them, you can now use it.

4. Check app notifications

Another simple but effective tip is to check your app notifications. Sometimes notifications for some applications are disabled, due to which notifications do not arrive on the iPhone. You can check if notifications are enabled in apps by going to Settings > Select Notifications as shown in the screenshot below.

You will now see all the apps that regularly send notifications on your iPhone. Click on the app that is not receiving notifications on your iPhone and turn on “Allow notifications” as shown below.

Isn't it that simple? Just follow these steps and enable notifications in all important apps like Mail, Calendar, Message, etc. to allow push notifications.

5. Connect to a stable network

You need a stable internet connection to support all your apps and their push notifications. Unless your iPhone is connected to a strong Wi-Fi network or cellular data, you won't receive notifications instantly.

To connect to Wi-Fi, visit Settings > tap on Wi-Fi > Turn it on and finally select your preferred network and connect to it by entering its password.

To turn on your cellular data (if you have an active data plan), tap Settings > tap Cellular Data > turn it on.

Note. If you find that the Internet connection is not strong enough due to a network problem while traveling, be patient until you get a good network and then try to connect again.

6. Re-login to your Apple ID account

Your Apple ID is the email address you use to sign in to the App Store and other Apple services. If everything works as expected, you enter your Apple ID early on (most likely during initial setup).

You need to re-sign into your Apple ID account. This is one of the frequently used methods when there is a problem with notifications on an iPhone. To sign out of your Apple ID, go to Settings > Apple ID, iCloud, iTunes Store, and App Store.

7. Sign out of iCloud and then sign in again

iCloud is a great way to sync your devices, from photos to files to web history. But when you encounter some problems, sometimes you need to log out of iCloud. Follow this guide to learn how to do this on iPhone.

Signing out of iCloud in iOS 10.3 is a little different than in the past and includes a new Apple ID banner.

Open Settings, then tap the Apple ID banner at the top of the screen (Apple ID, iCloud, iTunes, App Store). Scroll down and click " Go out" > « Sign out of iCloud".

The second method is for iOS versions 10.2.1 and lower. Open Settings on your iPhone, tap " iCloud">Scroll down and tap " Go out" > « Go out" > « Deletefrom iPhone».

Now go back in. That's all, notifications should work, if this doesn't help you, see the tips below!

8. Update iOS on iPhone

We all know that Apple releases iOS updates to introduce new and improved features to your devices and fix bugs that may be causing issues where notifications are not received on your phone.

9. Restore iPhone

Restore your iPhone to fix the error that prevents notifications from coming to your iPhone, this fix should be your last option. This method resets your iPhone, making it as fast as if you had just bought it.

You will eventually lose all your saved data and settings and thus, it is important to save them before trying this method. Follow the steps below to restore iPhone via iTunes.

1. Connect your iPhone to your computer. Click Browse > Create a copy now as shown in the screenshot below.

2. Then “Click Restore iPhone”, iTunes will pop up a confirmation message. Finally click "Restore" and wait for the process to complete.

3. Once this is done, restart your iPhone and set it up again to check if push notifications work on it.

Important note. Although this is a tedious way to fix notifications not working on iPhone, this method is known to solve the problem 9 out of 10 times. Once again, we advise you to choose this method only if none of the other solutions will work.

Apple is responsible for the correct operation of Push notifications in iOS. Any third-party application that wants to send notifications to the user must use Apple servers for this. The scheme looks like this: the developer will set up his own server, which accesses Apple's Push Notification Service (APNS), which in turn sends notifications to users on their devices.

Therefore, if a specific application does not send you notifications, then the problem lies in the crooked hands of the developer, who cannot properly configure the interaction of his server with APNS. If you stop receiving absolutely all notifications, then try the following instructions.

Sign out of your Apple ID account

Apple uses your Apple ID to identify your devices. This is how the company understands where to send notifications. The first thing to do if you have problems receiving Push Notifications is to sign out and sign in again to your Apple ID. You can do this in Settings > iTunes Store & App Store.

Reconnect your device to iCloud

A similar step should be repeated with the iCloud cloud service, which is responsible for synchronizing data between devices and with Apple servers. You can do this in Settings > iCloud.

iOS doesn't have many tools for solving problems, reboot being the main one. Let us remind you that a reboot is different from a regular power off/on. You can restart your device by long pressing the power button and the Home key on older devices and long pressing the power and volume down button on the iPhone 7 and iPhone 7 Plus.

Check Do Not Disturb Mode

If the system is set to Do Not Disturb mode, you will not hear notifications at the specified time. Make sure you don't turn it on permanently. This is understandable if there is a crescent icon in the device’s status bar.

Check your application settings

iOS has a very flexible notification system that allows you to customize each application the way you want. It can send Push notifications, it can show notifications only on the application icon, with banners at the top of the screen, it can show or not show notifications on a closed screen. In short, there are many options, all of them can be viewed in “Settings” > “Notifications”. If, when you first launched the application, you accidentally blocked it from sending notifications, you can always change this setting in this menu.

Check the mute button

Absurd, but, as practice shows, extremely useful advice. A small switch on the side of the iPhone has no effect on how Push notifications work, but it does mute system notification sounds. Thus, if you accidentally switch it, you may not hear important notifications.

Fans of the VKontakte social network often encounter the problem of lack of push notifications. Windows with quick dialogues do not pop up, which causes some inconvenience. Problems can be different, we will try to talk about them and understand the methods of solution.

Problematic issues with notifications in VK

In fact, dealing with each problem is not difficult. Among them are the following:

1. Social network site updates, server overload and other technical issues. You can often encounter something like this when global changes occur in a social network. Many features are unavailable, including push notifications;
2. Global account settings failed. Perhaps you yourself or your relatives could accidentally or intentionally change some parameters in VK. The solution to the problem involves checking individual parameters and returning the required values ​​to their original position;
3. Changing settings in private conversations with multiple people. The appearance of messages is often annoying and intrusive, so some users turn off certain elements and complain about the lack of pop-up windows;
4. The browser does not support java scripts. Of course, this is rare today, but problematic issues do arise. Only one remedy will help here! What exactly, read further in the article.

Technical points: waiting and updating

In this section we will try to solve problems with points No. 1 and 4. As for the first, everything is quite simple here. Updates and system overloads are temporary and you will need to be patient and wait. How long will this inconvenience last? It all depends on the specific situation:

1. If a major revision of individual elements of the site is carried out, the process will take up to 8 hours. During this time, individual modules will be rebooted, connections will be established, and functionality will be checked. To keep track of updates, we recommend subscribing to the official development group on VK;
2. Server overload can also be a problem when working with notifications. Now the developers have reduced the load on the site, but sometimes it is possible to encounter the phenomenon, especially in the summer. There is only one solution, wait and hope to correct the situation on your own. If red errors occur, we recommend clearing your browser cache.

Applications for working in the web environment are a different story. Some programs do not support java scripts or are simply blocked in global settings. Use different software, reset everything to its original values, or reinstall the latest version of the software. We've sorted this out, now let's move on to the parameters for VKontakte.

Incorrect or broken settings

Often the problem appears due to incorrect or broken parameters. The issue can be resolved through the following steps:

1. You need to go to the appropriate section. This is done by clicking on the name icon in the upper right corner;
2. In the new “Settings” window, you will need to find the “Notifications” section, after which sliders will appear on the central screen. They must be in the right position. If it's wrong, correct it;
3. In the case of mass dialogs, you need to check whether the corresponding function is enabled directly in the dialog. To do this, go to the desired chat, find the three dots at the top, and select “Disable/enable notifications.”

The problem is solved, in some cases you will need to log out and log in and clear the cache. We hope the tips helped and you eliminated the inconvenience. You also need to pay attention that VK uses notifications by email and SMS, we will talk about this in future articles.
