Yes, this includes a binary file, but it is only for the tests, and it is
free software since I wrote it. The source is here:

Previously, `fdroid update -c` would only create the new metadata, but
would not add the new apps/apks to the repo. That required a second run of
`fdroid update`. This has been fixes, so this test makes sure it stays
fixed, in a very generic way.
Make sure that fdroid can find aapt in the current config, otherwise exit
with an error. Some users don't have build_tools set, and their SDK does
not include the build-tools in the default versioned dir, so this should
warn them of what is wrong.
This allows the user to set the path to their Android SDK from the command
line. This option is named after the standard env var ANDROID_HOME, as used
in the build.xml generated by `android update project`. --android-home
takes precendence over the ANDROID_HOME env var if it is set.
