Understanding activity lifecycle

I am just starting my experience with Android development (I am watching tutorials right now). I looked at the activity lifecycle on the Android developers page, and I realized that the activity always goes through the onResume() method before it's visible to the user. Assuming I will be using no fragments in the activity, does that mean that most of the code logic should be within the onResume() method, and I should just inflate the layout once inside the onCreate() at the beginning?

Please Refer the site for the better understanding of the activity lifecycle https://developer.android.com/guide/components/activities/activity-lifecycle and also this for brief understanding https://www.javatpoint.com/android-life-cycle-of-activity

Now answering your question onCreate() is not just for inflating the layout. The main part of the core logic is written here and onResume() is called when you minimize the or open the app once again it is called again and again but onCreate() is called once untill and unless the control is not forwarded to another activity

Like in Java the start running from public static void main(String[] args){ }

In Android(Activity) the first line will be executed will be from onCreate() and not from the onResume()

if you will practice the same and will habitual of this process again and again then you better understand what i m trying to tell nothing can be more useful than you practice and your understanding try to print the toast or Log on each and every state of the activity lifecycle and you better understand this without the help of anyone

Cheers Happy Coding!
