啓動InCallScreen活動

我做這利用了Android的呼入電話屏幕與後續的代碼的應用程序：啓動InCallScreen活動

Intent inCallIntent = new Intent(); 
inCallIntent.setClassName("com.android.phone", "com.android.phone.InCallScreen"); 
startActivity(inCallIntent);

但我收到了如下錯誤：

我知道，來自某處的許可被錯過了。但是，可能是什麼？

更新：權限是既不 android.permission.CALL_PHONE 也不 android.permission.CALL_PRIVILEGED

一下添加到AndroidManifest.xml中

android.permission.CALL_PHONE

或

android.permission.CALL_PRIVILEGED

而且你是不是錯過了撥號的電話號碼，通常你在意向數據中設置了這個號碼。如果你想撥打電話或使用其他Intent actions

Intent intent = new Intent(Intent.ACTION_CALL); 
intent.setData(Uri.parse("tel:+15554441212")); 
startActivity(intent);

感謝您的回答，但所需的權限不是您提到的任何人。我仍然有同樣的權限問題。 – jiahao

Caused by: java.lang.SecurityException: Permission Denial: starting Intent { cmp=com.android.phone/.InCallScreen } from ProcessRecord{449ae8e0 1495:....callmesoon/10099} (pid=1495, uid=10099) requires null

這是根本原因，你需要設置你的意圖就是這樣，它在應用程序manifest資源配置文件應用程序組件的雙項的產生是由於。您可能已在清單文件中多次聲明瞭InCallScreen活動。只需再檢查一次。
