Java 无法使用带有GoogleAppClient的GPS获取当前位置

我正在尝试在我的应用程序中使用一个按钮，当用户单击该按钮时，该按钮将收集设备的纬度和经度。按钮工作正常，但它没有从我的GPSHelper类调用class方法。在此方面的任何帮助都将不胜感激。我正在我的实际设备上进行测试和尝试，如果有帮助的话，我不会使用模拟器。谢谢你的帮助

这是我的GPSHelper类，在这里我放置了GPS使用的所有权限检查和代码

这就是我获得位置更新的方式

    }
});

MyLocation mLocation = new MyLocation(this);
mLocation.getLocation(this, new MyLocation.LocationResult() {

    @Override
    public void gotLocation(Location location) {
        //Your Logic
    }
});
