Android Service組件在新進程中的啟動過程

1、startService

在Android系統匿名共享內存（Anonymous Shared Memory）Java調用接口分析，http://blog.csdn.net/jltxgcy/article/details/31414509一文，Client調用了如下代碼：

public class Client extends Activity implements OnClickListener {  
     public void onCreate(Bundle savedInstanceState) {  
        .....
        startService(new Intent("shy.luo.ashmem.server")); 
        ..... 
     }
..
}

下面我們就分析整個流程，直到執行：

public class Server extends Service {  
    public void onCreate() {  
        Log.i(LOG_TAG, "Create Memory Service...");  
  
        memoryService = new MemoryService();  
  
        try {  
            ServiceManager.addService("AnonymousSharedMemory", memoryService);  
            Log.i(LOG_TAG, "Succeed to add memory service.");  
        } catch (RuntimeException ex) {  
            Log.i(LOG_TAG, "Failed to add Memory Service.");  
            ex.printStackTrace();  
        }  
  
    }
    .....
}

2、整個過程和Android Activity組件的啟動過程http://blog.csdn.net/jltxgcy/article/details/35984557，幾乎一致。只是ActivityRecord換成了ServiceRecord，mActivities換成了mServices，而且少了兩個步驟，見下圖：
