Error handling pitfalls in Scala

There are multiple strategies for error handling in Scala.

Errors can be represented as [exceptions][], which is a common way of dealing with errors in languages such as Java. However, exceptions are invisible to the type system, which can make them challenging to deal with. It's easy to leave out the necessary error handling, which can result in unfortunate runtime errors.

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

• XCode is installed (via the App Store)
• XCode command line tools are installed (xcode-select --install will prompt up a dialog)
• Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

diff=$(cargo fmt -- --check)
result=$?

if [[ ${result} -ne 0 ]] ; then
    cat <<\EOF
There are some code style issues, run `cargo fmt` first.
EOF
    exit 1
