Just a real quick and simple question: The original class when making an android

  • 0

Just a real quick and simple question:

The original class when making an android app is called “MainActivity”. Will I have any issues if I rename it “Main”?

(In my research, I see that it can be renamed, but I am unsure if this will create complications to give it the name “Main”. I wanted to ask before messing up my program and digging myself into a hole. Thanks!

    No, no problem. There are a few things to keep in mind, though:

    • All references to MainActivity must reroute to Main.
    • All references in the manifest for the main activity (the one to launch) must be changed to Main. (Pay most attention to <activity android:name="..." .../>.)
    • Anyone currently using your app will lose the shortcut in their launcher if you change the main activity class name.
    • MainActivity is more descriptive–I’d honestly keep it like that.

    I would recommend you read this Google developer blog about “What You Can’t Change”.
