Profiling Applications

The profiler keeps track of every method in your application. For a particular emulation session, it figures out how much time was spent in each method and how many times each method was called.

The SDK supports offline profiling. Data is collected during the emulation session. After you close the emulator a profiler data snapshot is written to a .prof you can load and view in the SDK. As you view the snapshot you can investigate particular methods or classes and save a customized snapshot (a .nps file).

Note - This feature might slow the execution of your application.
