我不认为有一个简单的方法来做到这一点。呼叫获取preferredActivities（）在 PackageManager ，并通过筛选的名单，其中，IntentFilter的＆GT ; 你回来，试图找到一个匹配的意图可能工作

Can we know that user has set default application for particular action? i. e. android.intent.action.CALL_PRIVILEGED

Suppose I my application also provide called on action of Call_privilaged. but user has set inbuilt dialer as default launcher for Call_privilaged action.

My question is can I know pro grammatically that user has set dialer as default launcher for Call_privalged action.

I do not think that there is an easy way to do this. Calling getPreferredActivities() on PackageManager, and sifting through the List<IntentFilter> you get back to try to find a match for your Intent might work.
