🏷️ This repository contains demonstrations on how to use notifications in android.
🏷️ Notifications are used to display a message outside the UI of the application. Each notification contains an option to add a action for it, which can be used to navigate into the application.

Notifications before Oreo

• User could disable notifications per application basis and this was not useful for the user. If he ends up doing this, we would not be able to show any notifications at all.
• Based on the channel we can make the user categorize the notifications.

Notification channel on Oreo and Higher

• From Oreo which is API-26 displaying a notification became a little complex
• Now we define a notification channel, purpose of using the notification channel is to give the user more control on notifications displayed and have access to the noise they make

What happens what the code of Notification channels are invoked prior to Oreo devices

• There wont be any effect since the notification channels only work on oreo and higher versions.
• There will not appear any crash as such.

Support for android-13

𝙱𝚊𝚌𝚔𝚐𝚛𝚘𝚞𝚗𝚍

• There is a new change that android is bringing for android-13 which is also called Tiramisu and API-33 where there is a runtime permission, user has to approve before the notification has to be posted from a app in device.
• This is different that the already existing permissions where user can turn on/off on per each notification channel.
• Its protection level is marked dangerous ☣️

When the app is built with compile-SDK and target-SDK is API-31 which is android-12 also known as snow-clone	🏷️ When you run this on android-Pie which is API-28 device, no notification permission is displayed. 🏷️ We don't need to handle the runtime permission, instead just create the notification channels
When the app is built with compile-SDK and target-SDK is API-31 which is android-12 also known as snow-clone	🏷️ When you run this on android-13 which is API-33 device, even though we have not asked the app to display runtime permission, android device forcefully displays it if the code executes any lines that involve creation of channels. 🏷️ If the user approves it, application can post the notification. 🏷️ If the user denies it, this is dangerous since not only user will not be able to post notification also this dialog will never again unless you reinstall the app.
When the app is built with compile-SDK and target-SDK is API-33 which is android-13 also known as Tiramisu. After adding manifest permission and handeling the runtime permission	🏷️ Notifications appear only when the user approves the permission 🏷️ If the user dosen't approve it, the notifications will not appear.
