啓動已安裝的應用程序的某些應用程序的詳細信息導致強制關閉

Question

我正在處理其清除瀏覽器歷史記錄的應用程序。作爲該過程的一部分，我將用戶發送到瀏覽器的APPLICATIONS_DETAILS_SETTINGS屏幕，以便他們可以按下「強制停止」按鈕，該按鈕將關閉當前在瀏覽器中打開的任何窗口。這是我用來打開瀏覽器包的應用程序詳細信息活動的代碼。

killBrowserIntent = new Intent(); 
    killBrowserIntent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS"); // I have tried "android.intentaction.VIEW" here as well. 
    killBrowserIntent.setData(Uri.parse("package:com.android.browser")); 
    ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.applications.InstalledAppDetails"); 
    killBrowserIntent.setComponent(cn); 

這對很多設備都很有用。但是我對這個測試的設備之一，導致強制關閉與以下日誌：在設備上手動

要挖它遠一點我走進設置 - >管理應用程序 - >瀏覽器和注意到當我這樣做時被解僱的Intent已經捆綁了Extras。

這是從日誌的原意時，這一活動是手動啓動：

09-23 08:23:59.470: INFO/ActivityManager(231): Starting: Intent { act=android.settings.APPLICATION_DETAILS_SETTINGS dat=package:com.android.browser cmp=com.android.settings/.applications.InstalledAppDetails (has extras) } from pid 3540 

這是當它從我的應用程序推出的原意：

09-23 08:21:26.231: INFO/ActivityManager(231): Starting: Intent { act=android.settings.APPLICATION_DETAILS_SETTINGS dat=package:com.android.browser cmp=com.android.settings/.applications.InstalledAppDetails } from pid 3497 

有沒有人跨越這樣的事情呢？對我來說，找出需要捆綁並添加到Intent以便在設備上正確啓動的最佳方式是什麼？

我找到了InstalledAppDetails活動的源代碼，it can be found here但我的例外中引用的行是1：onCreate和2：blank之外。

有沒有一種方法可以偵聽在手動打開此活動時觸發的Intent，並從中解開其他附加組件，以便我知道它們是什麼，從而我需要將其添加到我的意圖中？

我想刪除setComponent()電話。不應該需要它（假設文檔是正確的），並且調用setComponent()來獲取不屬於你的組件並不是一個好主意。操作字符串應該將其路由到適當的活動。
