AndroidX Security State Libraries Offer Deeper Security Insights

Google has released two new libraries called AndroidX Security State and Security State Provider. These tools allow apps to check the security status of individual Android components, rather than relying on the overall security patch level.

This change is significant because it gives a more detailed view of a device's security state. Previously, a phone's security patch level was used as an easy way for apps and businesses to determine if a device was up to date.

However, this method had its limitations. Android can update different parts of the OS separately, so some updates come directly from manufacturers while others are updated through Google Play without requiring a full system update.

The new libraries will allow apps to check which security fixes are already installed, what the latest available fixes are, and whether an update is waiting to be installed on a particular device. This information can be used by apps where security is particularly important, such as banking apps.
