Android 4.0+读取APN发送彩信时出错

Question

java.lang.SecurityException: No permission to write APN settings: Neither user 10099 nor   current process has android.permission.WRITE_APN_SETTINGS.

编译发送彩信代码时出现此错误的原因是什么？为什么我不能在Android 4.0及更高版本中读取APN？

Answer 1

我直接复制了来自CommonsWare的here的答案。

这似乎是故意的改变。 git commit where they added this defense包含以下评论：

 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，您的问题会导致他们考虑添加单独的读取权限，但至少目前这是4.2中的回归。
