Summary:
The Android SDK installation on Linux is really dumb. The emulator binary
is dynamically linked and ships with some `.so`s that need to be either in `LD_LIBRARY_PATH` or `$CWD`.
For some reason, there's no script, so you have to manually `cd` into the directory in order to
run it. ¯\_(ツ)_/¯
