Copy on steroids is a JetBrains plugin that can be used to copy code from Android Studio (or any other flavor of IntelliJ) and paste it into a blog post.
I found it much easier to use, and better much better highlighting for cutting and pasting Android code from Android Studio to a blog post. Example:
The default causes long lines to wrap. If you want a scrollbar to appear instead, as above, you have to pop into HTML and add "overflow-x: auto" to the first <div> of the pasted code, and add "display: inline-block" to the first <pre>.
There is source in Github; all it needs is an open source license, and adding a setting that lets you choose scrollbars over line wrapping would be very easy.
