How to test function for execution timing in android?

Question

I have got stucked where one of my function is taking some time to execute. I have a hierarchy of objects in object using object models and ArrayList(s). I just want to know the techniques by which I can debug the code to check which statement of code is taking time in execution.

Answer 1

Two solutions :

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

Answer 2

Simply use this.

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

long MethodeDuration = (endTime - startTime);
