開啟程式的入口有很多個：

 

shell 命令列運行；

Launcher待機介面執行；

狀態通知欄運行；

案頭捷徑運行；

軟體中調用運行；

 

安裝軟體後執行“OPEN”運行！

 

前面幾項，調用程式的代碼如下（參考：com.android.Launcher/.Launcher.java）：

 

Intent intent = new Intent(this, TestActivity.class);<br />intent.setAction(Intent.ACTION_MAIN);<br />intent.addCategory(Intent.CATEGORY_LAUNCHER);<br />intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);<br />intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);<br />this.startActivity(intent); 

 

而安裝軟體後，點擊“Open”調用的代碼如下（參考：com.android.packageinstaller/.InstallAppDone.java）：

 

Intent intent = new Intent(this, TestActivity.class);<br />this.startActivity(intent); 

 

如果使用者安裝軟體後立刻執行“Open”，運行程式後，按HOME鍵返回到後台，然後再通過別的幾種方法運行程式，則會再起一個MAIN程式。這是因為Intent的處理機制是，先比較Activity，再比較Action、Flag、bnds。。。，前後兩張方式的Action不一樣，一個有LAUNCHER ACTION，一個沒有，所以會認為是啟動兩個不同的INTENT。

 

目前只想到一個簡單的處理方式：

 

程式入口MAIN程式：SplashActivity.java

程式原入口程式：LoginActivity.java

 

啟動程式後，在狀態通知欄上添加快捷通知，代碼如下：

測試流程：

 

a、軟體本地安裝；

b、安裝後執行“Open”；

c、運行軟體會從SplashActivity添加NOTICIFICATION TestActivity；

d、跳轉至SplashActivity（附帶LAUNCHER ACTION）；

e、再跳轉至TestActivity；

f、點擊BUTTON，跳轉至Test2Activity；

g、下拉狀態通知欄，點擊程式通知，可以正常運行程式。

 

TODO: 安裝軟體後執行OPEN後，從待機介面運行程式，還是會啟動兩個一樣的ACTIVITY，這個問題沒有解決！：（
