What's the difference between android and com.android?
<p>What's the difference between android and com.android? </p>

<p>For instance, the file android/nfc/ErrorCodes.java has a different content than com.android/nfc/ErrorCodes.java - both file exist in the Android's source code.</p>

<p>I want to know why there is a package called android, and also one called com.android. Why com.android was not enough so they also made android, with no dots? I want to understand why the content of the files with the same name is different. </p>
