I'm trying to get my game working on Android. I've ported it with the free version of Apportable and it works quite well, but I haven't been able to implement the gyroscope feature.

`CMMotionManager` gets initialized but the motion updates never start (or at least `handleDeviceMotion:` never gets called). The motion manager's `isAccelerometerActive` property is always NO, but `isAccelerometerAvailable` is YES.

Using `[NSOperationQueue mainQueue]` doesn't help either. 

This is how I initialize the motion manager:

```
self.motionManager = [[CMMotionManager alloc] init];
self.motionManager.gyroUpdateInterval = .2;

[self.motionManager startDeviceMotionUpdatesToQueue:[[NSOperationQueue alloc] init]
                                                withHandler:^(CMDeviceMotion *motion, NSError *error) {
                                                    dispatch_async(dispatch_get_main_queue(), ^{
                                                        [self handleDeviceMotion:motion];
                                                    });
                                                }];

```

It produces the following message to logcat:

```
E/Sensors (  507): HAL:ERR open file /sys/bus/iio/devices/iio:device0/dmp_event_int_on to write with error 2
E/Sensors (  507): HAL:ERR can't disable DMP event interrupt

```

I have no idea what this means...
I'm testing the app on Asus Nexus 7.

Is there something special I need to do to use CoreMotion with Apportable?

Edit:
[Here's](https://www.dropbox.com/s/0imnlbwksjrg5rb/CoreMotionTest.zip) a simple test project I created to demonstrate the issue.
