ionic3

I have developed an app using Ionic 3 framework. I would like to measure the CPU and memory usage of my app. What is the best practice to do so? You must not use AndroidStudio and XCode to measure the memory usage of the Ionic app . Why? Here is the comment from Ionic team member Unfortunately we have not been able to reproduce this issue on our end.

This leads to adding ContactPage and HelloPage to declarations and entryComponents arrays within @ngModule , which would not be lazy-loaded. So, this leads to the question, can you substitute strings, doing away with the imports and double array declaration, and have this?
