maybe call this "Android APKs", so in the future we can drop here other APKs we
might need?

I don't think we want this in build/android/. I think it belongs somewhere in
third_party and should only be DEPSed in for android checkouts, similar to how
we handle the android SDK in third_party/android_tools.

So for android_tools we've created and maintain a separate git repo that is then
DEPsed. I'm fine putting this in another directory, but I'm reluctant to create
a new repo for a single apk.

One idea is checking it into the android_tools repo, as it is used as a testing
tool on Android. WDYT?

was this something we built ourselves? we should probably add how to get this
info on the upgrade instructions.

To save us a few clicks, maybe also add here the full command, e.g.:

$ repo init -u https://android.googlesource.com/platform/manifest -b tradefed

+  - Extract WifiUtil.apk from prebuilt tradefed.jar:
+    jar xf prebuilts/misc/common/tradefed/tradefed-prebuilt.jar \
+        apks/wifiutil/WifiUtil.apk
+  - overwrite WifiUtil.apk with the file extracted from the jar
