Step #5: Update the Manifest

Now, we can add our widget to the manifest file. Edit AndroidManifest.xml

to look like the following:

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="apt.tutorial"

android:versionCode="1"

android:versionName="1.0">

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

<activity android:name=".LunchList"

android:label="@string/app_name">

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

<intent-filter>

<action android:name="android.intent.action.SEARCH" />

<category android:name="android.intent.category.DEFAULT" />

</intent-filter>

<meta-data android:name="android.app.searchable"

android:resource="@xml/searchable" />

<meta-data android:name="android.app.default_searchable"

android:value=".LunchList" />

</activity>

<activity android:name=".DetailForm">

</activity>

<activity android:name=".EditPreferences">

</activity>

<receiver android:name=".AppWidget"

android:label="@string/app_name"

android:icon="@drawable/icon">

<intent-filter>

<action

android:name="android.appwidget.action.APPWIDGET_UPDATE" />

</intent-filter>

<meta-data

android:name="android.appwidget.provider"

android:resource="@xml/widget_provider" />

</receiver>

</application>

</manifest>

In particular, note the element towards the bottom – that is

where we are teaching Android where our code and metadata resides for

this app widget. The intent filter for APPWIDGET_UPDATE means that we will

get control when Android wants us to update the app widget's contents,

such as when the app widget is first added to the home screen.
