This isolation prevents potentially harmful code within the Android container from interacting with code outside the Android containers.Īndroid is instrumented using part of the core Play Services called VerifyApps to recognize potentially harmful app behaviors and in certain situations to shut down and remove a harmful app. The Android framework runs in a container that isolates it from other containers and OS modules using Linux functionality called "namespaces." Android is granted only specific privileges to view and interact with Chrome OS hardware resources, such as keyboards, cameras and communications. Security extends beyond container sandboxing with SELinux, the secure version of Linux implemented in Android 4.3 in 2013 and Chrome OS since 2012 or earlier. App developers often optimize app performance by compiling critical modules into ARM object code because almost all Android mobile devices have ARM instruction set compatible processors. Over 90 percent of the top 100 Android apps include native ARM object code.

The full Android framework is implemented in a Linux container that isolates Android from the rest of the Chrome OS and apps in a sandbox.Ī hardware abstraction layer (HAL) has been built between Android and the Chrome OS that runs native ARM code on Chromebooks using processors with the ARM instruction set and emulates it on Chromebooks using Intel processors. The Chrome OS has taken advantage of recent work by Docker and other cloud containers to give Chromebooks Android-app compatibility. The Chrome OS is a subset-stripped of everything other than what is needed to manage the underlying hardware and services, such as security, authentication and communications needed by a secure browser. Merging the Chrome OS and Android teams last October, as well as sharing common operating system elements, should in this case prove successful.Īndroid is a superset of Linux with additional mobile features and many platform-specific APIs. Running apps created for one platform on a different platform naturally draws suspicion because many attempts have failed due to instruction set compatibility, security or poor emulation performance. + More on Network World: Google I/O 2016: Every Android app – really – is coming to Chrome +
