Move byline notification

hey guys ando welcome back to new video in this video you will learn about local notifications in android i do have one very old video about that in my android fundamentals playlist but that is quite outdated and i think i can explain that quite better nowadays and with more details i will show you how to update notifications so what we'll basically build is um a basic app you can click on a button and then a notification will show which is simply an increment counter here we can drag this down and then there is an increment button if we click that then we basically just update that notification so just something very basic you need and very many apps you will learn how to do that and i also show you here and there how you could customize this notification so how you could change it how you could maybe add an image here and things like that but right at the beginning i want to make clear that this is about local notifications and not about push notifications because especially beginners often confuse these two push notifications are those that the server sends to a device and that requires some more setup that usually requires some kind of um either third-party sdk that supports that or you use something like firebase fcm but there is a lot more setup involved if you actually want to show push notifications in your app and also if the app is actually um completely closed here you will actually see how you can yeah kind of just show a notification locally from within your app by for example clicking a button or by yeah just some other kind of event that fires could also be that you use something like alarm manager to show a notification for example if you have some kind of calendar app that a notification is shown as at a spec at a specific time but it's just not the case that the server decides when to show this notification so before we actually jump into coding i want to talk about a concept that is um yeah very relevant for notifications and that is called notification channels so whenever we actually want to send notifications or use notifications in android apps we need to create something called a notification channel at least for starting from some kind of android version and i think it's quite an abstract concept so um i actually want to quickly talk about that here what a notification channel is it's basically something that summarizes related kinds of anime and not animations notifications of course and we can see these notification channels in the app settings so if we actually minimize the app here and we hold on it go to app info then click on notifications you will see we have a counter notification so for our yeah basically whoops this notification here or that's not the notification that...
