What role does the AndroidManifest.xml file play in the structure of an Android application?

The AndroidManifest.xml file is the main configuration file of an Android application. It describes the structure and components of the app, as well as its system requirements.

Main functions of AndroidManifest.xml:

• Declaring all application components: Activity, Service, BroadcastReceiver, ContentProvider.
• Defining permissions needed by the app (e.g., internet access).
• Specifying the minimum and target SDK versions.
• Configuring themes, icons, intent filters, and other parameters.

Example from AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.app">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name">

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
</manifest>
