API 23 Manifest.permission.READ_SMS is always denied

I'm having a little trouble with Android 6 dangerous permissions feature, where the user has to explicitly grant some permissions. In my case, I request for an array of permissions with the following code:

public class SplashScreenActivity extends BaseActivity implements
    RefreshClientOptionsTask.IRefreshClientOptionsListener {

        private static final String [] DANGEROUS_PERMISSIONS = {permission.READ_PHONE_STATE,
            permission.READ_SMS,
            permission.ACCESS_FINE_LOCATION,
            permission.CALL_PHONE,
            permission.WRITE_EXTERNAL_STORAGE,
            permission.READ_EXTERNAL_STORAGE,
            permission.CAMERA
        };

        private void initPermissions() {
            List<String> missingPermissions = new ArrayList<String>();
            for(String permission : DANGEROUS_PERMISSIONS) {
                if(ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
                    missingPermissions.add(permission);
                }
            }

            if (missingPermissions.size() > 0) {
                String [] permissions = new String[missingPermissions.size()];
                ActivityCompat.requestPermissions(
                        this,
                        missingPermissions.toArray(permissions),
                        1);
            } else {
                // we have all permissions, move on
            }
        }

        @Override
        public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);

            for(int grantResult : grantResults) {
                // handle denied permissions
            }
        }
}

When this code executes I'm presented with four permission request dialogs. After I press 'allow' in every dialog onRequestPermissionsResult is executed and grantResults argument contains all zeroes (PERMISSION_GRANTED) except for READ_SMS permission - it's equal to -1 (PERMISSION_DENIED). What's happening and how should I handle this situation?

I'm testing on a physical device running Android 6.0.

When dealing with Marshmallow's new permissions model, any required permission must be listed in the manifest, in addition to requesting the dangerous permissions at runtime.

In this case, it seems that you effectively did not have the READ_SMS permission in the manifest, which is why it was denied at runtime.
