联系人有android.permission.CALL_PRIVILEGED权限为什么还会报这个错？？

Question

android4.0.4的contacts有android.permission.CALL_PRIVILEGED这个权限，为什么还会报：

    java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.CALL_PRIVILEGED dat=tel:xxx flg=0x10000000 cmp=com.android.phone/.PrivilegedOutgoingCallBroadcaster (has extras) } from ProcessRecord{41878ad0 3991:com.android.contacts/10000} (pid=3991, uid=10000) requires android.permission.CALL_PRIVILEGED？

哪些大侠知道？

你是修改了Contacts么？如何操作的？是要自制rom？

修改了Contacts以后，要使用本身系统的签名，既然是自制rom，如何签名你应该知道。

签名完成后，要push进system/app然后重启，如果有必要，需要wipe data。原因在于你如果权限更改了，system/app里面的应用有的系统是不会更改权限的，需要重新建立权限列表，所以需要wipe data。
