Misleading file extension in android-29

[microdog]

The android.jar uploaded to Google Drive under android-29 is actually a RAR archive instead of a JAR archive.

This is very misleading and if someone wasn't aware of it, the project will not be able to be synced. (#76, #70 (comment))

$ file android.jar
android.jar: RAR archive data, v5
$ unrar l android.jar
