android: request permission at runtime

Question

I want to provide a functionality in my App for which I need the permission INTERNET.

However, not all user may want to use this functionality and since this is a very strong permission I don't want to force everyone to give it to the App if they want to use it, only if they want to use this functionality.

So I have to ask for that permission at run-time. the minimum sdk for the App is 15 and I don't want to set it higher.

The method requestPermissions(String[],int), which I can call in my Activity is only available with API 23, but I can callActivityCompat.requestPermissions(this,new String[]{Manifest.permission.INTERNET},0);, but it doesn't no dialog is shown.

And yes, I have checked if the permission is already granted:

if(ContextCompat.checkSelfPermission(this,Manifest.permission.INTERNET)!= 
PackageManager.PERMISSION_GRANTED)
    ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.INTERNET},0);

What am I doing wrong?
