After reading this post I started wondering what is required nowadays to build an app. Let's take an Android app as an example. I've heard of porters like PhoneGap, that convert your HTML/Javascript to Java (Android for as far as I know), but are there easier ways nowadays? I know very little about Java - my main focus is PHP. I do know a good bit of Javascript, though, so does anyone have experience with creating apps without knowing the main language in which those apps are usually written? Or better yet: what can you do in regard to creating an app when you have only knowledge of PHP and Javascript?
Edit: Hm, maybe this question would be better placed in the Software Development category huh?
