Hello, I finished watching 254's presentation recently and have begun working on a similar android app where it would find the target and send the data back to the roborio. I have opencv running on my phone and can run opencv functions fine.
What i am having trouble with is setting the exposure / iso values from within the code. I am trying to use CaptureRequest.set() and the app instantly crashes saying:
Code:
AndroidRuntime: FATAL EXCEPTION: Thread-3171
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.hardware.camera2.CaptureRequest$Builder.set(android.hardware.camera2.CaptureRequest$Key, java.lang.Object)' on a null object reference
My code is here:

Any help is appreciated,
