Capital characters in Android Project Packagename

Question

I want to use capital letters in android project package name. So can we use capital letters in package name?

Answer 1

In my opinion, you should not use capital letters in package name.

You will not be able to build the application with package name having capital letters in MAC and Windows.

So always use small letters for package name.

Answer 2

You can, but trust me you don't want to. Not only does it break convention, it can cause real problems. For example in android, android studio won't support it. This means if you switch IDEs, your code might not compile.

Best practice is to just stick to lower case and convention.
