I need to save a screenshot capture in the user gallery but the authorization is not automatically asked. I allowed permission in the Android manifest (WRITE_EXTERNAL_STORAGE) but it doesn't ask it for, I have to set it in the emulator settings. Does someone know how to ask authorization, as the location?
You could use the plugin PermissionsPlugin from nuget .
try
{
var status = await CrossPermissions.Current.CheckPermissionStatusAsync<LocationPermission>();
if (status != PermissionStatus.Granted)
{
if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Location))
{
await DisplayAlert("Need location", "Gunna need that location", "OK");
}
status = await CrossPermissions.Current.RequestPermissionAsync<LocationPermission>();
}
if (status == PermissionStatus.Granted)
{
//Query permission
}
else if (status != PermissionStatus.Unknown)
{
//location denied
}
}
catch (Exception ex)
{
//Something went wrong
}
