Android 基础(一)、androidmanifest.xml

androidmanifest.xml讲解

很多activity，service，broadcast的各种信息需要被打包起来用于安卓程序的执行，这种任务的机制就是androidmanifest

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

• action android:name="android.intent.action.MAIN" indicates that this is an entry point to the application
• category android:name="android.intent.category.LAUNCHER" places this Activity in the launcher(发射台) window

<application android:icon="@drawable/icon">
    <activity android:name=".chapter1" android:label="@string/app_name">  
         ......
    </activity>
</application>

• android:icon="@drawable/icon" indicates that this application uses icon as icon
• android:label="@string/app_name": app’s name
