The app is obviously quite popular and has a good rating:
23 downloads is quite popular?
Google was supposed to start testing all of the apps in the Play Store when it was discovered that some were not malicious until they were actually installed. The file is clean but once it is installed it "calls home" to download the malware.
This is the first time we have seen such an extensive feature set in one mobile application.
But as I mentioned, not the first of it's kind.
