當用戶在Android設備上啓動新應用程序時檢測

Question

我一直在嘗試檢測用戶何時在他/她的設備上啓動應用程序。

所以我發現了這個解決方案：

我加入一個線程內的代碼。因此，我的應用程序每3毫秒獲取一次日誌，但是我無法找到日誌之間的差異，所以我無法檢測到用戶應用程序啓動的代碼。

這是我得到的日誌的一個例子，當我加入這一行：

String w = log.toString(); 
Log.i("LockService","w ="+w);

使用此代碼，我怎麼能檢測到用戶啓動的應用程序？

Answer 1

讀取日誌是一個可怕的想法，也破壞了系統的各個版本。實際上，您可以註冊here：ACTION_PACKAGE_FIRST_LAUNCH，但請注意，這僅適用於API級別12+的廣播意圖。

Answer 2

您可以在日誌中檢測標記爲ActivityManager的應用程序啓動。

在日誌中您可以找到有用的數據。您可以檢測運行包。

例如：

06-06 16:09:06.007: I/ActivityManager(1663): Starting: Intent { act=android.intent.action.MAIN flg=0x10840000 cmp=com.android.phone/.InCallScreen } from pid -1 

它是com.android.phone包和InCallScreen開始第一頁。

您可以檢查包名稱並檢測目標應用程序何時啓動。
