Android各层打印栈的方法

1.Java层打印调用栈方法

RuntimeException here = new RuntimeestException("exception");

here.fillInStackTrace();

Log.w(TAG,"XXXXXX: " + this, here);

A. Thread.dumpStack()

B. Log.d(String tag,String msg, Throwable tr)

C. new Throwable().printStackTrace()

2. cpp层打出栈的backtrace

#include <utils/CallStack.h>

CallStack stack;

stack.update();

stack.log("XXXXXX",ANDROID_LOG_ERROR);

其中“XXXXXX”指的是TAG

3. c函数打调用栈

参考CallStack.cpp的实现，通过调用_Unwind_Backtrace完成

4. kernel打调用栈

dump_stack()
