INTRODUCTION
This Blog is all about memory management in Android. It provides information about how you can analyze & reduce memory usage while developing an Android app.
Memory management is a complex field of computer science and there are many techniques being
developed to make it more efficient. This guide is designed to introduce you to some of the basic
memory management issues that programmers face.
Memory Management in Android
Android is a Linux based operating system. It uses native open source C libraries which power Linux
machines. All the basic operating system operations like I/O, memory management and so on are
handled by the Linux kernel. Like Java and .NET, Android uses its own run time and virtual machine to
manage application memory. Unlike either of these frameworks, the Android run time also manages the
lifetime processes.
Each Android application runs in a separate process within its own Dalvik instance, relinquishing all
responsibility for memory and process management to the Android run time, which stops and kills
processes, necessary to manage resources. Dalvik is an open source, register-based virtual machine
(VM) that is part of the Android Operating System. The Dalvik VM executes files in the Dalvik
Executable (.dex) format. Resources are simple files in xml format.
Dalvik and the Android run time sit on top of a Linux kernel that handles low-level hardware
interaction including drivers and memory management, while a set of APIs provide access to all the
under-lying services, features and hardware.
A systematic examination and evaluation of data or information is very important so that we can
manage the available memory in an effective way. For this we have DDMS in Android Studio IDE,
using which we can analyze the memory being utilized. (IDE is Integrated Development Environment
which provides the platform for developing an app in Android)
DDMS
Let us understand DDMS now. Android studio includes a debugging tool called the Dalvik Debug
Monitor Service (DDMS). DDMS provides services like screen capture on the device, threading, heap
information on the device, logcat, processes, incoming calls, SMS checking, location, data spoofing,
and many other things related to testing your Android application.
