Runtime-Permissions | A simplified integration of android 's runtime permissions

i tried to set request 5 permissions check in my code

Of course I added all five to the manifest. and i also tried to deleted the app and reinstalled it.

but it doesnt ask permissions at all

this is my root class

I'm trying to implement a Xamarin.Forms application using Xamarin.Forms.Maps, however I always fall into the exception:

Java.Lang.SecurityException: my location requires permission ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION

I have already tried following the steps in this tutorial https://blog.xamarin.com/requesting-runtime-permissions-in-android-marshmallow/ but did not get results.

Would anyone have something more consistent to help me?

What I'm intending is to use an application very close to Uber and I can not progress if I can not get the location permissions.

My MainPage looks like this in my PCL:

I am developing a Xamarin.Forms app using the microphone. My app uses Android 7.1 (Nougat) on a Huawei P9-Phone. My android manifest includes:

I'm starting with Xamarin to be able to create an app that runs both on iOS and Android. The first thing I wanted to do is to click a button -> Open Gallery -> Select image -> Display selected image on a Image label

The current content of MainPage.xaml is:

I have followed the android guidelines for asking for permissions for Android Devices running VERSION.M and above namely (runtime-permissions), but the permission request dialogue is not shown, instead, the permission is automatically denied.

I am requesting users for READ/WRITE CONTACTS permission as well as other permissions as indicated by my manifest below.

The app requests for other permissions, such as access files, phone, SMS but does not request for read contacts permission.

Here is my manifest file

I have an app with a register activity. When the user registers he is asked for these two permissions:

• READ_PHONE_STATE
• READ_CONTACTS

User should be able to accept or decline both, or accept one and decline the other. Depending on that I would want to have 4 different results:

1. If the user allows READ_PHONE_STATE and declines READ_CONTACTS the result should be:register(name, email, password, getMyPhoneNumber(), false);
2. If the user declines READ_PHONE_STATE and allows READ_CONTACTS the result should be: register(name, email, password, "", true);
3. If the user declines both the result should be: register(name, email, password, "", false);
4. If the user allows both the result should be: register(name, email, password, getMyPhoneNumber(), true);

I have been trying to find a solution that would allow for these combinations for a while now, trying this, this, this, this, this and much more, but I couldn't find a working solution.

This is my original RegisterActivity:

On fresh install, when I click the button it will skip everything until
