Xamarin Android: create folder on PublicDirectory for my app

I have a funny but tricky problem with Android. In my Xamarin Forms project I want to create a folder where I store all files generated from my app so I can access to them easily via a FileManager.

Until this morning in Android I used

Environmentstring path = Android.OS.Environment.
                         GetExternalStoragePublicDirectory(
                             Android.OS.Environment.DirectoryDocuments).ToString();
Environmentpath += "/MyApp";
EnvironmentDirectory.CreateDirectory(path);

I added some new components to my solutions and now everything is denied.

System.UnauthorizedAccessException: Access to the path "/storage/emulated/0/Documents/MyApp" is denied.

I changed then the AndroidManifest.xml like

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="23" />
        <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
    <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.WRITE_GSERVICES" />
</manifest>

But now I can't create anything in this folder. Just for example, I'm using the same code in other my application and the result is

FileManager example

Any suggestions? Thanks

As user1230268 stated try to go to your app manager on your device and enable the permissions. For me it was

Settings > Device > Apps > YourAppName > Permissions > Storage

Enable it and you should be good to go.
