I'm trying to use the new Android camera2 api. I started with source from this tutorial : <http://jylee-world.blogspot.com/2014/12/a-tutorial-of-androidhardwarecamera2.html> . When I try to usb-debug-deploy it to any phone, I get a SecurityException from `CameraManager.openCamera(...)`.

My AndroidManifest looks like this:

```
<uses-feature android:name="com.android.hardware.camera2.full"/>
<uses-permission android:name="android.permission.CAMERA"/>

```

This seems to be what every tutorial I've been able to find does. I'm able to get permission for other actions; for example, I can make the camera vibrate just fine. I'm also able to enumerate cameras with `CameraManager.getCameraIdLists()` just fine, but I'm not sure if that actually requires permission. But I can't `openCamera`.

Are there some additional permissions I need? Am I doing something wrong?

Thanks for the help!

This is my full stack trace:
