Permission exception even though permission is set in manifest [duplicate]

问题

In my manifest I have:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

However, when I run my app and press the button that needs this permission I get the following exception:

Geofence usage requires ACCESS_FINE_LOCATION permission

How can I fix this?

I have the permission right under <manifest>

I am using Android 6.

This is my code:

   public void addGeofencesButtonHandler(View view) {
        if (!mGoogleApiClient.isConnected()) {
            Toast.makeText(this, getString(R.string.not_connected), Toast.LENGTH_SHORT).show();
            return;
        }

        try {
            LocationServices.GeofencingApi.addGeofences(
                    mGoogleApiClient,
                    // The GeofenceRequest object.
                    getGeofencingRequest(),
                    // A pending intent that that is reused when calling removeGeofences(). This
                    // pending intent is used to generate an intent when a matched geofence
                    // transition is observed.
                    getGeofencePendingIntent()
            ).setResultCallback(this); // Result processed in onResult().
        } catch (SecurityException securityException) {
            // Catch exception generated if the app does not use ACCESS_FINE_LOCATION permission.
            logSecurityException(securityException);
        }
    }
