When I call mCamera = Camera.open() it returns null, what could be causing this? My device is the Nexus 7.
I already have the permissions set in my AndroidManifest.xml:
<uses-permission android:name="android.permission.CAMERA" />
Figured it out,
You need to call
Camera.open(0).THIS IS ONLY VALID AND WORKING ON THE NEXUS 7 device, as it only has one camera, so is only useful if targeting that device only.
