If you are looking for Activities which has launcher, then you can use this Java code and convert to C#, https://stackoverflow.com/questions/6175821/get-a-list-of-every-launcher-in-android — Raviprakash, Mar 14 '18 at 05:35

Finally found the reason. here is the complete code.

string appName = PackageManager.GetApplicationLabel(PackageManager.GetApplicationInfo("com.google.android.gm", PackageInfoFlags.MetaData));

this returns "Gmail"
