Memory profilingIvan Kocijan

If you are an Android developer you probably hate this error:

java.lang.OutOfMemoryError

This error occurs due to various reasons but luckily there are tools for detecting and reducing memory leaks.

1. DDMS 2. Memory Analyzer (MAT) - http://www.eclipse.org/

mat/

TOOLS

DDMS

MAT

• MAT analyzes java heap dumps • DDMS creates an Android heap dump • To convert Android heap dump to Java we can use a tool called hprof. It comes with Android SDK and it’s used like this:

hprof-conv android.hprof java.hprof

With DDMS and MAT we can easily detect and stop memory leaks. By reducing memory leaks we can make our application work a lot better and faster but think before you do this. It takes time and at the end you might not get the desired result.
