Android Manifest File - androidmanifest xml - DataFlair

Android Manifest File

The manifest file in Android is generally created automatically as soon as the app is built in Android Studio.

Structure of a Manifest file in Android is:

<manifest>
   <application>
<activity android:name="com.example.applicationname.MainActivity" >
      </activity>
   </application>
</manifest>

The information that is stored in the Manifest file is as follows:

  • The name of the application’s package, it is generally the code’s namespace. This information is used to determine the location of the code while building the project.
  • Another component is the one, that includes all the activities, services, receivers, and content providers.
  • The permissions that are required by the application to access the protected parts of the system and other apps.
  • The features required by the app, that affect which devices can install the app from Google Play. These features include both hardware and software features.
  • It also specifies the application metadata, which includes the icon, version number, themes, etc.

The android manifest.xml file generally looks like the following:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.myfirstapplication">
   <application
       android:allowBackup="true"
       android:icon="@mipmap/ic_launcher"
       android:label="@string/app_name"
       android:roundIcon="@mipmap/ic_launcher_round"
       android:supportsRtl="true"
       android:theme="@style/AppTheme">
       <activity android:name=".MainActivity">
           <intent-filter>
               <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
       <meta-data
           android:name="preloaded_fonts"
           android:resource="@array/preloaded_fonts" />
   </application>
</manifest>

Element Tags of Manifest File

1.

It is the root element of this element. It consists of a package attribute package that tells the activity’s package name.

2.

It is the subelement of the manifest file that includes the declaration of the namespace. It contains certain attributes. These attributes declare the application components, and these attributes include:

  • icon
  • allowBackup
  • label
  • theme

3.

Activity is a subelement of application. It has the declaration of the activity that must be there in the manifest file. It also has certain attributes like name, label, theme, etc.

4.

It is an element in the activity, it describes the type of intent in which the Android components can respond.

5.

This element provides an action for the intent filter. Each intent filter must have at least one action element in it.

6.

This element adds the category name in an intent-filter.

7.

This element contains the operations that are provided by libraries or APIs.
