Cant log supportedPreviewSizes() in Java

Question

Hi I have a Javascript background and am learning Java... trying to simply output what the supportedPreviewSizes are but I only get a format like this:

android.hardware.Camera$Size@27eefd0

I need to get the width and height. I had tried this:

List<Camera.Size> previewSizes = cParams.getSupportedPreviewSizes();

for (int i = 0; i < previewSizes.size(); i++)
{
    // if the size is suitable for you, use it and exit the loop.
    Log.d("previewSize", previewSizes.get(0).toString());
    break;
}

I don't know why this is so damn hard in Java it doesn't seem intuitive at all. Javascript is way more intuitive console.log(your Object) wow so easy!

The Camera.Size class doesn't override toString(), so you get the default implementation, which, as you've seen, isn't very useful. You'll have to manually log the height and the width:

for (int i = 0; i < previewSizes.size(); i++)
{
    Camera.Size ps = previewSizes.get(i);
    Log.d("previewSize", "height: " + ps.height + ", width: " + ps.width);
}

Thank you! It's quite difficult to do the basics when just starting out. – Michael Paccione May 18 '21 at 23:45
previewSizes(i) should be previewSizes.get(i) for any readers... – Michael Paccione May 19 '21 at 03:33
@MichaelPaccione indeed - sloppy typing on my behalf, sorry about that. Edited and fixed. – Mureinik May 19 '21 at 05:34
