Editing the Manifest File Manually

The Android manifest file is a specially formatted XML file.You can edit the XML manually by clicking on the AndroidManifest.xml tab.

Android manifest files generally include a single <manifest> tag with a single <application> tag.The following is a sample AndroidManifest.xml file for an application called Multimedia:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.androidbook.multimedia" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">

<activity android:name=".MultimediaMenuActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action. MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>

<activity android:name="AudioActivity"></activity> <activity android:name="StillImageActivity"></activity> <activity android:name="VideoPlayActivity"></activity> <activity android:name="VideoRecordActivity"></activity> </application> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.SET_WALLPAPER" /> <uses-permission android:name="android.permission.CAMERA"></uses-permission> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="8"> </uses-sdk> <uses-feature android:name="android.hardware.camera" /> </manifest>

Here's a summary of what this file tells us about the Multimedia application:

■ The application uses the package name com.androidbook.multimedia.

■ The application version name is 1.0.

■ The application version code is 1.

■ The application name and label are stored in the resource string called @string/app_name within the /res/values/strings.xml resource file.

■ The application is debuggable on an Android device.

■ The application icon is the graphic file called icon (could be a PNG, JPG, or GIF) stored within the /res/drawable directory (there are actually multiple versions for different pixel densities).

■ The application has five activities (MultimediaMenuActivity, AudioActivity, StillImageActivity, VideoPlayActivity, and VideoRecordActivity).

■ MultimediaMenuActivity is the primary entry point for the application.This is the activity that starts when the application icon is pressed in the application drawer.

■ The application requires the following permissions to run: the ability to record audio, the ability to set the wallpaper on the device, the ability to access the built-in camera, and the ability to write settings.

■ The application works from any API level from 3 to 8; in other words,Android SDK 1.5 is the lowest supported, and the application was written to target Android 2.2.

■ Finally, the application requires a camera to work properly.

Now let's talk about some of these important configurations in detail.
