如何在清单文件中注册应用程序类？

Question

How to register my application class in my android manifest? I have looked at many tutorials online and still can not get it right. My application class is called Monitor.java . How do I register it in the Manifest file code below?

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.project"
    android:versionCode="1"
    android:versionName="1.0" >

<application
    android:allowBackup="true"
    android:debuggable="true"
    android:icon="@drawable/ic_launcher"
    android:label="xyz"
    android:screenOrientation="landscape"
    android:theme="@style/AppTheme" >

    <service
        android:name=".AudioService"
        android:icon="@drawable/ic_launcher"
        android:label="audioservice" >
    </service>

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

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

    <activity
        android:name=".Editor"
        android:screenOrientation="landscape"
        android:windowSoftInputMode="stateHidden" >
        <intent-filter>
            <action android:name="com.example.project.EDITOR" />

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

</application>

<application
        android:name="package.YourApplicationClass"  <--------
        android:allowBackup="true"
        android:debuggable="true"
        android:icon="@drawable/ic_launcher"
        android:label="xyz"
        android:screenOrientation="landscape"
        android:theme="@style/AppTheme">

Answer 2

Try this:

 <application android:icon="@drawable/icon" 
       android:label="@string/app_name" 
       android:name="Monitor">

Thanks.

Answer 3

Simple, put android:name attribute with your application class name in <application /> tag of Application's Manifest.xml

<application
 android:name=".Monitor"
   .... >

Update:

Application Class:

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's tag, which will cause that class to be instantiated for you when the process for your application/package is created.

More info look at http://developer.android.com/reference/android/app/Application.html

Answer 4

Well, you already have application class inside - starting with <application . If you have a custom class (that extends Application ) in your code and want it to start - put

android:name=".Monitor" (or full path like com.something.app.Monitor)

after <application tag (the same process as you would add an activity).

Answer 5

Just add an android:name=".Monitor" attribute to the application tag (I presume that the Monitor.java class is located in the root of the application package). Hope this helps.

Answer 6

what confused me is 'android:name' shows up multiple times in the manifest file. before creating an application class file, i had

android:name=".MainActivity"

after the 'activity' tag.

after creating the application file, everything in manifest file stays the same, except after 'application' tag, i add

android:name=".myApplicationClass"

my complete manifest file:

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

Answer 7

use this one

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testing"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="16" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Monitor"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>
