java.lang.NullPointerException Exception on Some Devices

[itt80]

It's working perfectly. But I get these exceptions on some devices

Fotoapparat
                .with(this)
                //.cameraProvider(CameraProviders.v2(this)) // change this to v2 to test Camera2 API
                .into(cameraView)
                .previewScaleType(ScaleType.CENTER_CROP)
                .photoSize(wideRatio(smallestSize()))
                .lensPosition(lensPosition(position))
                .focusMode(firstAvailable(
                        continuousFocus(),
                        autoFocus(),
                        fixed()
                ))
                .previewFpsRange(rangeWithHighestFps())
                .sensorSensitivity(highestSensorSensitivity())
                .frameProcessor(new SampleFrameProcessor())
                .logger(loggers(
                        logcat(),
                        fileLogger(this)
                ))
                .cameraErrorCallback(new CameraErrorCallback() {
                    @Override
                    public void onError(CameraException e) {
                        Toast.makeText(FotoApparatActivity.this, e.toString(), Toast.LENGTH_LONG).show();
                    }
                })
                .build();

It's occured this exception messages;

Why are the device models working stable? Are they unsupported?

You only select a wide ratio ( wideRatio(smallestSize()) ) so I assume these devices cannot generate a aspect ratio. Therefore the exception. use firstAvailable() selector or catch the error on these devices
