If you are using Unity 5.1, make sure to set the right Graphics API settings in the Player Settings for Android and iOS:

disable the "Automatic Graphics API" checkbox in the Graphics APIs list, make sure that only OpenGL ES 2.0 is included: Android: remove OpenGL ES 3.0 iOS: remove OpenGL ES 3.0 and METAL

Important : 1. In your Unity project:

Select the QCARWrapper.bundle in the Unity Project view (located under Assets > Plugins ), so that its settings are shown in the Unity Inspector Change the settings of QCARWrapper.bundle in the Unity inspector from "Any Platform" to "Standalone + Editor".

Rebuild

​OR:

2. In the Xcode project generated by Unity:

Go to Build Phases > Copy Bundle Resources Remove the QCARWrapper.bundle file from the list Rebuild

My unity3d version is 5 and 64bit ,Os is Windows7 64 bit.

my Problems solved .

Edit :

Unity editor couldn't show laptop camera ,But Rebuild Project , camera work . for example rebuild Android platform , and install .apk on device => application Ok .
