New ActivityResultContracts.RequestPermission() sample

Issue

Android 11

With the new Android 11, we have a change on permissions behaviour, adding:

• One Time Permissions
• Auto-reset permissions from unused apps
• Permission dialog visibility

Luckily, Android already give a method(RequestPermission) that deal with all this cases.

Developer Android Permission Guide

On the permission guide Request App Permission where this project is linked (end of the page) we can see the usage of ActivityResultContracts.RequestPermission() and ActivityResultCaller.registerForActivityResult.

What can make the developer confused because registerForActivityResult still on alpha for appCompat library.

Solution

Based on this, would be beneficial for the community to have a sample code for it. But since the library still not release this should be another sub-project until the appCompat release 1.3 and this code became the default one.

@Canato Yeah, thanks a lot for. Yep, I do the first approach right now and trying to find good solution, how to correct handle it. The second of course is better, but it is required a lot of staff just for small things, and if you have quite simple application it is a big pain 😃

But thanks a lot. 😃

@SuppressLint(“MissingSuperCall”) override fun onRequestPermissionsResult( requestCode: Int, permissions: Array<out String>, grantResults: IntArray ) { if (requestCode == myResquestCode) { if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) { getLastLocation() } else { requestPermission() } } }
