Android Memory Management

Android has a unique memory management model. Below, are the notes taken while we try to understand it thoroughly.

Activity Manager

Overview

The ActivityManager, among other things, is responsible for making sure that apps that are most important to the user and/or essential remain active. It does this by dynamically assigning values that roughly indicate the app's importance. When memory gets low these values are used to find the apps that need to be "trimmed." The memory from these "trimmed" apps is freed, making more available for the more important apps.
