既然logcat说的都是你想要的，为什么你不尝试添加权限呢

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission> 

---

你似乎有打电话的意图，但任何应用打电话都需要获得许可

要在应用程序标记之前将其添加到清单中，请添加以下内容

<uses-permission android:name = "android.permission.CALL_PHONE"/>

---

您必须在AppManifest.xml中添加此权限：

<uses-permission android:name="android.permission.CALL_PHONE" />

出现错误是因为您没有添加它。
