Directory Structure of Android
This file most important file in an Android project. This file contains an index of your application. Information about permissions, Activities, Services etc. have to be listed in this file. For better understanding take an example of a book. Every book has an index page at the start. This index page contains a list of all chapters. Inside chapters list of topics. So if you want to find the specific topic you can refer this index to directly jump to that section. The manifest file is also like an index of application where permissions, Activities, Services etc. are listed. An example of the Manifest file is below.
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
