本文基本Android8.1系统源码

#include <utils/CallStack.h>


    ALOGW("name=liuderu cpp stack111");
    android::CallStack stack;
    stack.update();
    stack.log("InputDispatcher", ANDROID_LOG_DEBUG, "  ");

#include <utils/CallStack.h>

ALOGW("name=liuderu cpp stack111");

android::CallStack stack;

stack.update();

stack.log("InputDispatcher", ANDROID_LOG_DEBUG, " ");

stack.log的第一个参数是LOG_TAG，第二个是固定的ANDROID_LOG_DEBUG
