Memory keeps rising without getting memory leak notification from leakcanary

I am new to android Profiler and still a noob at memory management. At first, I am having a notifications from LeakCanary so I fix them and successfully removed the leakage so the LeakCanary stops sending me notifications. But when I use the android Profiler I just noticed that the memory usage was rising bit by bit when I open a certain activity and then destroy it using finish(); method. Below are the sample screenshots of my Profiler when I open and close the OrdersActivity.

Here is the SS of total memory used before opening and closing the OrdersActivity

And here is the SS of total memory used after opening and closing the OrdersActivity

Also here is the stacktrace of the LeakCanary

I want to know if this occurrence of rising memory is normal? If not, is there a way to stop this? I am willing to show my codes If you need them in order to help me. I just didn't include it because it was too long.
