Android Memory Leak

Android Memory leak is terrible security lapse for Android application developers. It may come up as a disaster for any android application if the storage is present in mass and is not deleted.
Memory leak can create multiple issues in proper functionality of any android application.

Generally, we have two types of known memory errors:

A) Out of Memory Leakage

In this type of memory leakage the memory error tries to allocate memory that the pile of application has. It’s quite difficult to find the leakage but it can be identified once our application starts receiving crash report but this also not a good process to adapt as all the crashes are not due to memory leakages.

B) Memory Leakage for holding object without purpose

This type of memory leakage occurs if the object is held for a long period of time even after its task has been finished then also a memory leakage can occur. Though, we have garbage collector which keeps on collecting data objects but the garbage collector is also useless if any application hold these objects.

To outline the memory usage of an application Android SDK offers two ways one of which includes heap dumps and other being tracker.

Here are 3 Android Memory Leak Tools you must check out if not done yet:

Eclipse Memory Analyzer (MAT)

It gives analysis of how much storage is used by applications. It’s quite helpful in terms of tracking memory leakage. MAT can also provide the usage of memory for a particular time period.

Valgrind

Valgrind tools are very dynamic and can automatically detect android memory leak and threading bugs, and profile your programs in detail. Valgrind is an instrumentation framework for building dynamic analysis tools, so developers can build their own customized analysis tools.

DDMS

DDMS (Dalvik Debug Monitor Server) can directly sense storage allocation and help developers to work on memory leakage in android applications as it displays memory leakage in apps.
Android SDK has directly this tool in it.

The developers need to really need to keep focus on memory leakage aspect of an application and choosing the right Android memory leak tools act as an effective measure to make your app a success.
