ContextCompat.checkSelfPermission vs Compat.checkSelfPermission

Question

My app have next settings

• minSdkVersion 8
• targetSdkVersion 23
• compileSdkVersion 23

And I use simple code to get READ_PHONE_STATE permissions

...
    final List<String> permissions = Arrays.asList(
            Manifest.permission.READ_PHONE_STATE);

    if (!permissions.isEmpty()) {
        ActivityCompat.requestPermissions(activity,
                permissions.toArray(new String[]{}), 1);

    }
...

When I use:

• ContextCompat.checkSelfPermission
• ActivityCompat.requestPermissions

Everything works fine.

But when I use:

• Context.checkSelfPermission
• Activity.requestPermissions

App just didn't show dialogs.

Anyone have explanation why this happens?

I trying to minimize all dependencies and use Context and Activity instead ContextCompat and ActivityCompat
