• Update request permission.
• Cách dùng:
• Tạo biến xử lý call back sau khi được cấp quyền.

private val permissionsLauncher by requestPermissionLauncher { status ->
                when(status) {
                    PermissionStatus.Granted -> {
                        Timber.i(this@MainFragment::class.simpleName,"Permission status: Granted")
                    }
                    PermissionStatus.Denied -> {
                        Timber.i(this@MainFragment::class.simpleName,"Permission status: Denied")
                        requestRuntimePermissions(PermissionStatus.Denied)
                    }
                    PermissionStatus.ShowRationale -> {
                        Timber.i(this@MainFragment::class.simpleName,"Permission status: ShowRationale")
                        requestRuntimePermissions(PermissionStatus.ShowRationale)
                    }
                }
            }

• Các quyền khi yêu cầu cấp quyền:

override fun getPermissionsArray(): Array<String> {
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            arrayOf(Manifest.permission.ACCESS_FINE_LOCATION)
        } else {
            arrayOf()
        }
    }

• Handle các action khi show cấp quyền:

override fun requestRuntimePermissions(permissionStatus: PermissionStatus?) {
        when(permissionStatus)
        {
            /*
            * To help find situations where the user might need an explanation,
            * Android provides a utility method, shouldShowRequestPermissionRationale().
            * This method returns true if the app has requested this permission previously and the user denied the request.
            * */
            null ->{
                var shouldProvideRationale = false
                for (permission in getPermissionsArray()) {
                    if(ActivityCompat.shouldShowRequestPermissionRationale(requireActivity(), permission))
                        shouldProvideRationale = true
                }
                if (shouldProvideRationale)
                    PermissionStatus.ShowRationale
                permissionsLauncher.launch(getPermissionsArray())
            }

            PermissionStatus.ShowRationale -> {
                // Permission Rationale
            }
            PermissionStatus.Denied ->{
                // Permission Denied
            }
            PermissionStatus.Granted ->{
                // Permission Granted
            }
        }
    }

• Gọi requestRuntimePermissions() để xin cấp quyền
• Gọi super().permissionApproved() để kiểm tra các quyền đã được cấp chưa.
• Có thể xử lý callback cấp quyền bằng hàm có sẵn (đã deprecated):

 /**
     * Handles the callback from the OAuth sign in flow, executing the post sign in function
     * TODO replace this function to result launcher
     */
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        when(resultCode){
            AppCompatActivity.RESULT_OK -> Timber.i(this::class.simpleName, "Permission: RESULT_OK")
        }
    }
