Measuring Android WebView Content Size

Situation: you’re loading content into an Android WebView that’s embedded in another view (i.e. not a fullscreen WebView) and you want to ensure the WebView resizes to the height of the content it contains.

Easy, right? Loaded question: it’s Android so you know the answer is absolutely not. StackOverflow answers provide many ways to potentially do this, but most don’t work. I only found one way – using some Javascript magic – to reliably get the content height.
