Note that your application uses the Camera Java API, this indev uses the Camera2 NDK API.

I think this cannot be compared directly. Could you test it in your specific case, whether the camera is somehow available through the NDK? Please note that the Camera2 NDK API only works on devices with API Level 24+ (Android 7.0).

As far as I have seen the camera in your device must also specifically support the Camera2 API. Cameras that are designed for the old API are only available in the Java version of the Camera2 API. 

You can check this in Java with: https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#INFO_SUPPORTED_HARDWARE_LEVEL

The NDK version only supports cameras that are on the hardware level LIMITED or above.
