The AndroidManifest.xml file contains information about your package, including applications such as activities, services, broadcast receivers, content providers, etc.

It performs some other tasks also:

  • It is responsible to protect the application to access any protected parts by providing the permissions.
  • It also declares the android api that the application is going to use.
  • It lists the instrumentation classes. The instrumentation classes provides profiling and other informations. These informations are removed just before the application is published etc.

This is the required XML file for all Android applications and is located inside the root directory.

A simple AndroidManifest.xml file looks like this:


<manifest xmlns:android="http://schemas.android.com/apk/res/android"  
    package="com.javatpoint.hello"  
    android:versionCode="1"  
    android:versionName="1.0" >  
    <uses-sdk  
        android:minSdkVersion="8"  
        android:targetSdkVersion="15" />  
    <application  
        android:icon="@drawable/ic_launcher"  
        android:label="@string/app_name"  
        android:theme="@style/AppTheme" >  
        <activity  
            android:name=".MainActivity"  
            android:label="@string/title_activity_main" >  
            <intent-filter>  
                <action android:name="android.intent.action.MAIN" />  
                <category android:name="android.intent.category.LAUNCHER" />  
            intent-filter>
