I'm not 100% sure on how the `@TargetApi` and `VerifyError` work together. However it is something along the lines of: * Class loader needs `CleanCacheService`. * At this point, it loads the bytecode for that class and verifies that it all makes sense. * The bytecode within the method targeted at API 21 is not understood by earlier APIs, because the entire `Os` class was introduced in 21. * By putting it into a different class, that class is only loaded at runtime on devices with API of 21 or higher. Previously, `@TargetApi` + the relevant guard condition to check the build version at runtime suffices to prevent this. However it seems that if the entire class does not even exist on earlier APIs, then it is no longer good enough.

FAQ
- Why does F-Droid require "Unknown Sources" to install apps by default?
Because a regular Android app cannot act as a package manager on its own. To do so, it would require system privileges (see below), similar to what Google Play does.
- Can I avoid enabling "Unknown Sources" by installing F-Droid as a privileged system app?
This used to be the case, but no longer is. Now the Privileged Extension is the one that should be placed in the system. It can be bundled with a ROM or installed via a zip, or alternatively F-Droid can install it as a system app using root.
