Android runtime service optimization for execution inside LXC

The immense popularity of Android applications has created the demand to make these applications available on various devices we use on a daily basis. Consequently, with the emergence of autonomous driving solutions, Android has become the operating system of choice for different infotainment applications. The execution of the Android operating system inside LXC (Linux container) provides an environment that is suitable for car infotainment systems. When executing Android in the containerized environment within the embedded system, optimizations are essential for decreasing the memory usage. In this paper, we propose a solution for effectively reducing resource consumption and improving application performance. By analyzing the permissions needed by Android applications, we can determine which Android services are not required in certain scenarios, and disable them. We show that by using the proposed optimization, a significant decrease in memory consumption is achieved for a set of applications typically available in car infotainment systems.
