启动已安装的应用程序的某些应用程序的详细信息导致强制关闭

Question

我正在处理其清除浏览器历史记录的应用程序。作为该过程的一部分，我将用户发送到浏览器的APPLICATIONS_DETAILS_SETTINGS屏幕，以便他们可以按下“强制停止”按钮，该按钮将关闭当前在浏览器中打开的任何窗口。这是我用来打开浏览器包的应用程序详细信息活动的代码。

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); 

这对很多设备都很有用。但是我对这个测试的设备之一，导致强制关闭与以下日志：在设备上手动

要挖它远一点我走进设置 - >管理应用程序 - >浏览器和注意到当我这样做时被解雇的Intent已经捆绑了Extras。

这是从日志的原意时，这一活动是手动启动：

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 

这是当它从我的应用程序推出的原意：

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 

有没有人跨越这样的事情呢？对我来说，找出需要捆绑并添加到Intent以便在设备上正确启动的最佳方式是什么？

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

有没有一种方法可以侦听在手动打开此活动时触发的Intent，并从中解开其他附加组件，以便我知道它们是什么，从而我需要将其添加到我的意图中？

我想删除setComponent()电话。不应该需要它（假设文档是正确的），并且调用setComponent()来获取不属于你的组件并不是一个好主意。操作字符串应该将其路由到适当的活动。
