queryIntentActivities抛出的DeadObjectException

Question

我很少从DeadObjectException获得queryIntentActivities。

这就是我在这个问题上找到的所有内容：http://comments.gmane.org/gmane.comp.handhelds.android.acra/184所以我尝试调整我的代码，如下所示（此代码中的注释来自上面提到的帖子）。

我正在尝试跟随：

旧代码

List<ResolveInfo> ril = pm.queryIntentActivities(mainIntent, 0);

新代码

List<ResolveInfo> ril = null;
try
{
    ril = pm.queryIntentActivities(mainIntent, 0);
    // process data...
}
catch (DeadObjectException e)
{
    // possibly happens because this process is still running but app is currently being updated by the android system
    // if this is really true, we can ignore the exception as the complete progress will be stopped anyways...
    L.e(e);
}

问题

我无法捕获异常，因为根据定义它永远不会被queryIntentActivities抛出。我现在可以做些什么来避免这次崩溃？我不想在这里捕捉所有例外情况。

此外，我不确定此异常是否真的发生，我的应用在尝试拨打queryIntentActivities时已更新，这只是基于上述帖子的假设。谁能证实这一点？
