How To Detect Android Memory Leaks

One of the most horrible security lapses in Android is memory leak. They are malicious because one piece of code may crash the applications or may create issues. Memory leaks may occur because of creating storage in heap and fail to delete it. It is a serious issue for applications and it is caused by a pointer that does not get returned in the loop.

Memory errors can be divided into two types, out of memory and memory leakage. Out of memory is that trying to assign more memory that the application's heap has. The leakage is difficult to find. You can identify the leakage in the app while receiving the crash report. In addition, application crashes may occur due to several issues. Hence, finding out the leak is the toughest part in the development. The leakage occurs due to holding an object for a long period even after its purpose has been finished. Usually the garbage collector collects all the dead or unused objects, which does not have any links to them. If the programs hold the objects, then the garbage collector will not be able to clean it up.

Many tools are available for testing the leaks, eclipse memory analyzer, Mat plugin, tool traceview of android SDK and Valgrind. Android SDK offers two important ways to sketch the memory usage of the app. Allocation tracker and heap dumps are two main ways. Allocation tracker is helpful for the developers to find out the memory usage of the app in a given period. Nevertheless, it does not provide the overall status of the application's heap.

Heap dumps are the impressive tool for cache analysis and it is like the image of app's heap. Every developer faces a challenge in analyzing and understanding the usage of RAM in the app and optimizing it. After releasing the unused objects from the application, the application may retain more storage spaces than required.

Eclipse Memory analyzer (MAT) is the best tool to analyze the storage usage of applications. This tool is useful for tracking leakage in memory and if offers an opportunity to analyze the application at a regular interval. MAT offers a snapshot of the memory usage for a certain period. Remember, MAT does not give the reason for the creation of object or it cannot show the objects that the garbage collector has collected. However, you can find out the leakage immediately and find ways to stop it.

DDMS tool is used to detect storage allocation and this will be available in Android SDK directory. This tool will also display the leakage in Android application. Besides, it displays the information about the objects, which are not garbage collected and about the data storage occupied by the objects. If you place a reference link in the context, will lead to leak lot of storage and it is called as context related memory leak. This can be avoided in two ways. First solution for this is to avoid releasing the context outside of app's limit. Using of application context is another solution, by this, the context will retain as long as the application lives.

Every Android phone comes with pre-installed APKs, which enables them to effortlessly install and utilize apps, making your life a whole lot easier.

The software has been added with features, which are designed with keeping in mind the Android application development process. It will greatly simplify and optimize the entire process of software designing and development for the OS.

This IDE will also come with templates that can be used to build applications with standard Android look and feel. It has Lint, which is a tool to address version compatibility issues and other potential bugs. It also has ProGuard, which obfuscates code to hinder reverse engineering. The software also has Gardle, which is used as an automated tool in the process of Android mobile software development.

A blog of Android Developers Blog with title "Android Studio: An IDE built for Android" explains that the Studio IDE just not offers extensible build tools that fit you project requirements but also extends further to larger development environment. The blog further explains that the software has a powerful code editor to support features like advanced code refactoring, deep static code analysis and smart editing. The blog also mentions that the Studio IDE will soon include great drag-and-drop UI features and lets developers harness the power Google services.

An article of Android Developers, the official site for Android developers, titles "Getting Started with Android Studio". It explains how developers can download the Early Access Preview of Android Studio v0.1 for Windows. The article explains the entire installing process too. It also explains how Mac OS X and Linux users can download the software in their desktops. Information on Starting a Project is also available in this article.

Mobile software development community is praising the efforts of Google to facilitate Android developers.
