Now, let's come to the implementation of LED Service Entity that is resided in Framework layer. For legacy architecture, the LED Service Entity is quite straightforward. The LED Service Entity code is resided in frameworks/base/service/java/com/mokoid/server/LedService.java.

Application Test Code

The test code is resided in apps/LedClient/src/com/mokoid/LedClient/LedClient.java as following:

1. package com.mokoid.LedClient;  
2. import com.mokoid.server.LedService;  // Import LedService in FrameWork layer
   
3. import android.app.Activity;  
4. import android.os.Bundle;  
5. import android.widget.TextView;  
6.   
7. public class LedClient extends Activity {  
8.     @Override  
9.     public void onCreate(Bundle savedInstanceState) {  
10.         super.onCreate(savedInstanceState);  
11.         // Call an API on the library.  
12.     LedService ls = new LedService();  // Instantiate LedService  
13.     ls.setOn(1);                       // via public methods to control low level hardware 
    
14.     ls.setOff(2);  
15.           
16.         TextView tv = new TextView(this);  
17.         tv.setText("LED 1 is on. LED 2 is off.");  
18.         setContentView(tv);  
19.     }  
20. }
