Android package names

In an Android application, I notice that the package name of a class does not have to match the name that was generated when I created the new project. In other areas, Java is insistent that everything matches. I would like to understand why this is not the case for package names, and what the implications are.

Example: I create a new project named TextToSpeech, using my own reverse domain name. This gives a package name of com.lexogram.texttospeech; the path to the MainActivity.java class file is TextToSpeech/app/src/man/java/com.lexogram.texttospeech/.

I now go to a TextToSpeech tutorial and copy-and-paste the code into my project. This code uses com.example.texttospeech as the package name, both in the MainActivity class and in the AndroidManifest.xml. I run the project, and everything works fine.

Does this mean that each activity can use a different package name, so long as the name is used consistently across all files in the activity?

What it means is that your project can have multiple packages inside of it.

Java documentation explains them nicely:

To make types easier to find and use, to avoid naming conflicts, and to control access, programmers bundle groups of related types into packages.
