[Android] 在 Service 中啟動 Activity
[Reference] http://www.myandroid.tw/bbs-topic-66.sea

!!很重要!!
Server要啟動Activity一定要加上 Intent.FLAG_ACTIVITY_NEW_TASK的Flag

Intent i = new Intent();
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);

[Android] 用 bind 啟動 Service

[Reference] http://www.ozzysun.com/2010/11/android-service_02.html

Service 裏要有如下的程式，在 onBind 傳回 mBinder, Activity 裏的 onServiceConnected() 才能收到 bind 完成的訊號, 預設傳回 null 沒用。

public class LocalBinder extends Binder {
     MusicService getService() {
        return  MusicService.this;
    }
}
private final IBinder mBinder = new LocalBinder();
@Override
public IBinder onBind(Intent intent) {    
    return mBinder; 
}
