Answer 1

Xamarin.Forms (Android solution)

MainActivity.cs

• For apps that target Android 5.1(API level 22) or lower, there is nothing more that needs to be done.
• Apps that will run on Android 6.0(API 23 level 23) or higher should ask Run time permission checks.

protected override void OnCreate(Bundle bundle)
{
    if (Build.VERSION.SdkInt >= BuildVersionCodes.M)
    {
        if (!(CheckPermissionGranted(Manifest.Permission.ReadExternalStorage) && !CheckPermissionGranted(Manifest.Permission.WriteExternalStorage)))
        {
            RequestPermission();
        }
    }
    LoadApplication(new App());
}

private void RequestPermission()
{
    ActivityCompat.RequestPermissions(this, new string[] { Manifest.Permission.ReadExternalStorage, Manifest.Permission.WriteExternalStorage }, 0);
}

public bool CheckPermissionGranted(string Permissions)
{
    // Check if the permission is already available.
    if (ActivityCompat.CheckSelfPermission(this, Permissions) != Permission.Granted)
    {
        return false;
    }
    else
    {
        return true;
    }
}
