android的camera2 API的所有自动参数是什么

Question

I'm developing a camera app using the Android camera2 API, And I need the camera to have always the same configuration, like focus, white balance, exposure, etc.

I already disabled AF, AE and AWB, but it still seems to automatically set the white balance. I was wondering if is there some other automatic configuration I should disable.

I didn't find anything like it on Google.

i just ran into the same issue... In my case it turned out, that there was a function in the template i was using, which reset the control mode to automatic.

protected void updatePreview() {
    if(null == cameraDevice) {
        Log.e(TAG, "updatePreview error, return");
    }
    captureRequestBuilder.set(CaptureRequest.CONTROL_MODE, CameraMetadata.CONTROL_MODE_AUTO);
    try {
        cameraCaptureSessions.setRepeatingRequest(captureRequestBuilder.build(), null, mBackgroundHandler);
    } catch (CameraAccessException e) {
        e.printStackTrace();
    }
}
