May 2021 update: For those having trouble with location permissions on API 30 or higher, here is a solution. Within requestPermissions(), on the third if() statement regarding background permissions, change the code to: if(!hasLocationBackgroundPermission() && hasLocationForegroundPermission()) In this case, the button must be clicked twice to request background location permissions. (I'm sure there's a more correct way to implement this, but this is an easy way to correct the problem in this case). To learn more why this works, look up "Request location permissions" in the Android Developer documentation. There is a statement that says requesting foreground and background permissions at the same time will be ignored. Furthermore, background permissions will not be granted unless foreground permissions were previously granted.
Hello There is one more way to done it using single click only just add this code again in onRequestPermissionsResult permissionToRequest.clear() if (hasForegroundPermission() && !hasBackgroundPermission()) { permissionToRequest.add(Manifest.permission.ACCESS_BACKGROUND_LOCATION) } if (permissionToRequest.isNotEmpty()) { ActivityCompat.requestPermissions(this, permissionToRequest.toTypedArray(), 0) }
Hey Philipp, I love your videos. I just wanted to point out that this workflow is (sorta?) deprecated according to the documentation. I'd love to see an updated video covering the new paradigm. I've been trying to wrap my head around it, and was kind of disappointed you don't have a more recent video on this, since you're who I turn to to clarify stuff like this! In any case, keep up the great work. Loving the newer Compose content.
Hey , why is it sorta deprecated? Are you referring to the fact that he is not using shouldShowRequestPermissionRatinonale()? Is the rest of his code good for use?
@@isown8131 It's more that there are more modern APIs to manage permissions. For the most part, it's still a great video. I don't remember the specific thing I had problems with.
I would also love this. I just ran into the message `getSerializedExtra` is deprecated and the alternative (passing the class as a param) is also not working.
Hi, Philipp, thanks again for your awesome content! Can I ask why at 11:10 you specified that in this case "Make sure you use ActivityContext instead of ApplicationContext"? Still confused about when to use ActivityContext or ApplicationContext
Hi Philipp, Great video once again. Could you please create one more video showing how to use new Activity Contract API for requesting permissions and handling denying and rejections. Thanks in advance,
I want to say a big thanks Philipp. Your videos have a very easy-to-grasp logic and have been a big help with my studies. I would like to request if you could make an update on the permissions video. When I follow the session after launching the app, it does not show the request to accept permissions.
Hi phillip i could really understand about every video you've put into work. But there's one that still confused me. Why we use hasWriteExternalStorage with "function (private fun)" instead of "variable (var/val)" Please help if someone could give an explanation. Thankyou
I think it might be because a function definitively gets called when you invoke it (and only then assigns a value to the expression you mentioned) whereas a variable gets assigned wherever in the code you write it. You can't "call" a variable to recheck whether the value of that expression has changed, you'd just have to rewrite the variable or expression all over again any time you'd want to recheck if it has changed. That's my understanding of it anyway. I could be totally off the mark.
what is the difference between dexter permissions and android default permissions is dexter more powerfull then the default android permissions and will this code run with android 11 as well?

Hi Phillip, thanks a lot for your tutorials, they are great. I am having problem with this part though, I've done everything you did but Im not getting the Permission prompt after clicking a button, nothing happens. I am using API 30 (Pixel 2) - could that be a problem? Thanks a lot
It is not working on A11 like the pop up for asking for permission is not showing up at all on clicking button, the log says button was clicked but nothing regarding the permission while the app works properly on A10 or below
@@betaaccount7450 you are right! thanks! also tried A C's suggestion, it works too: if(!hasLocationBackgroundPermission() && hasLocationForegroundPermission())
hey, the = is there because 'hasWriteExternalStoragePermission' returns a single Int value and because of that, it can be written like this. This is how single expression functions are described in documentation: Single-expression functions When a function returns a single expression, the curly braces can be omitted and the body is specified after a = symbol: example: fun double(x: Int): Int = x * 2
@8:02 Bro how come you can compare Manifest.permission to PackageManager.PERMISSION_GRANTED?? is PackageManager an abstract class and so does it need to be implemented or inherited first?
Hey, I hope you already have the answer. If not, PackageManager is an abstract class (as you had surmised) but what we are comparing isn't PackageManager itself but a public static property within PackageManager itself. The property is an integer type and I suppose the checkSelfPermission method returns an integer, which makes both the PackageManager.PERMISSION_GRANTED and the checkSelfPermission comparable to each other. If you have never done Java, think of a static property like a companion object which you can use without actually creating an object of a particular class in Kotlin.
Very nice explanation , dear sir I have two questions 1. In my mobile this code only asks for COARSE_LOCATION and EXTERNAL_STORAGE but not for BACKGROUND_LOCATION I don't know why ??? 2.

If your app targets Android 10 (API level 29) or higher, remove the ACCESS_BACKGROUND_LOCATION permission from your app's manifest. When you remove this permission, all-the-time access to location isn't an option for the app on devices that run Android 10.
Nice video as always!!! I have a question with this line: if(permissionsToRequest.isNotEmpty()) { ActivityCompat.requestPermissions(this,permissionsToRequest.toTypedArray(),0) } I dont understand well why you use ActivityCompat.requestPermissions(this,permissionsToRequest.toTypedArray(),0) Thanks a lot for such amazing videos
The Internet permission is not considered as a dangerous permission by Android. As such, you only need to declare it within your manifest file (it does not need user acceptance since it does not compromise your privacy).
Same here, but I believe that is due to API change. I understand the concepts, just need to practice what the documentation states. So I plan on recreating this after I finish the complete playlist.
If the API your phone or emulator uses is past 29 this tutorial is slightly outdated. I think when it comes to requesting location you can still use almost the exact same format the video uses but you can't request background location and foreground (course or fine) location at the same time like he does. You need to first request foreground location and once that has been accepted you can seperately request background location. Try commenting out the request for background location alltogether and this video should still work and will get you a permission prompt asking if you'll accept the app using foreground location.
OK but this doesn't explain at all when you should request the permissions, what to do once you've gotten them, when yo might need to request them again or anything about how permissions work in the context of a full Android application
Android studio 2023 SUCKS big time.

Hello
There is one more way to done it using single click only
just add this code again in onRequestPermissionsResult
permissionToRequest.clear()
if (hasForegroundPermission() && !hasBackgroundPermission()) {
permissionToRequest.add(Manifest.permission.ACCESS_BACKGROUND_LOCATION)
}
if (permissionToRequest.isNotEmpty()) {
ActivityCompat.requestPermissions(this, permissionToRequest.toTypedArray(), 0)
}
