How to check function for runtime in Android?

Question

I am stuck when one of my functions takes some time to complete. I have a hierarchy of objects in an object using object models and ArrayList (s). I just want to know the methods by which I can debug the code to check which code instruction takes time to execute.

Answer 1

Two solutions:

• Show yourself the elapsed time (fairly simple and extremely powerful imho): How do I execute a method in Java?
• Get more details with Traceview: http://developer.android.com/tools/debugging/systrace.html

Answer 2

Just use it.

long startTime = System.nanoTime(); YourMethode(); long endTime = System.nanoTime(); long MethodeDuration = (endTime - startTime);
