我有一个问题的读书的APN 在Android的4.2版的（是读，不写APNS），它抛出一个安全异常：

I have a problem reading APNs in Android v4.2 (Yes reading, not writing APNS), it is throwing a security exception:

没有写权限APN设置：无论是用户10068也不电流   过程中有android.permission.WRITE_APN_SETTINGS。

No permission to write APN settings: Neither user 10068 nor current process has android.permission.WRITE_APN_SETTINGS.

用于在所有的previous平台相同code，没有人知道任何工作围绕这个？

Same code used to work on all previous platforms, does anyone know of any work around to this?

谢谢！

推荐答案

这似乎是故意的改变。该git提交他们加入这一防御包括以下意见：

This appears to be an intentional change. The git commit where they added this defense includes the following comment:

由于数据库可能包含CORP密码，我们应该保护它。使用相同的权限为写入到数据库的读取是潜在的破坏性作为写。

Since the DB may contain corp passwords, we should secure it. Using the same permission as writing to the DB as the read is potentially as damaging as a write.

可以想象的是，您的问题将导致他们考虑增加一个独立的读取权限，但至少从目前来看，这是4.2的回归。

It is conceivable that your issue will cause them to consider adding a separate read permission, but at least for the time being, this is a regression in 4.2.
