title: Android app package name
body: <p>When creating an Android application using Java, you place your classes into packages such as <code>com.example.appName</code></p>
  
  <p>However, in the Android XML manifest file, you also specify the package there.</p>
  
  <p>It is my understanding that the Google Play Store, where Android apps are uploaded, uses the package name as a unique identifier for your app.</p>
  
  <p>So, which package name actually identifies your app/APK file? And can the package names in your code be different to the package name in the manifest?</p>
