Do you really use your reverse domain for package naming in java?
I am a beginner in Android programming. I made a few Android projects using Eclipse. while I was catching up with some Android tutorials I could see everyone using "com" as a starting word of package name. I want to know why, as far as I have known it’s just package name but why does everyone start with "com"? Do I have to follow? or is there any specific reason programmatically?
Because the people creating those projects happen to own domain names ending in
.com.No, but you need to ensure that your app’s package is unique across the entire Google Play Store (assuming that is how you plan to distribute the app). The easiest way to do that is to create your Java package based upon a domain name that you own and plan to use for marketing the app. Whether that domain name ends in
.comor.netor.bizor whatever is up to you.
