引言

  此时的我吃着火锅唱着歌，进行着Android P(此P非彼P，Android 9)的适配工作。我真的只能说每次Android版本的迭代更新，都是对我们的一次炼狱般的摧残啊，各种适配啊，我真的想说fuck the coding。但是吐槽归吐槽，为了我热爱的coding事业，让我们愉快的适配起来。这不问题又来了，当我们修改liblog源码时提示error: VNDK library: liblog’s ABI has EXTENDING CHANGES，木得办法兵来将挡水来土掩，只能上了。

注意：本文演示的代码是Android P高通msm8953平台。

一.问题现象

当我们尝试对Android源码下面的system/core/liblog源码目录下面的文件添加一些接口时，适配问题出现了，编译一直报错，如下所示：
