I am developing a Huawei custom Theme. I was trying to change some Google apps (Documents, Sheets and Slides) icons. So I used as address their package name e.g. com.google.android.apps.docs.editors.slides
Since it didn't work, I tried with some activities, found in the manifest file, but no one worked yet. (for example com.google.android.apps.editors.homescreen.HomescreenActivity, which is the first one that appears when I open Slides);
So the question is: is there a way to identify which is the main activity, nay, which is the activity who defines app icon?
