PreviewView

[blockjke]

Hello, help me please. I need to screen cameraview, but screenshot saves everything (buttons etc.) besides previewview

    previewView = findViewById(R.id.view_finder);
    
            imageButtonCapture = findViewById(R.id.camera_capture_button);
    imageButtonCapture.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyyMMddHHmmss", Locale.US);
            File photofile = new File(getBatchDirectoryName(), mDateFormat.format(new Date())+ ".jpeg");
            Falcon.takeScreenshot(MainActivity.this, photofile);

        }
    });
    
    Thanks!

Hey, I somehow missed notifications for this, sorry.

I think the answer is very similar to this issue also the one with Google Maps or with Lottie

Looking at the PreviewView docs:

This class manages the preview Surface's lifecycle. It internally uses either a TextureView or SurfaceView to display the camera feed...

Such cases are unfortunately not supported and if the onDraw(Canvas) draws nothing, there is not much Falcon can do about this and I would seek a different way for taking screenshot for PreviewView.
