android系统堆栈打印

一. java层

Java 堆栈打印：Log.d(TAG,Log.getStackTraceString(new Throwable()));

二.C++层堆栈打印
 #include <utils/CallStack.h>
 android::CallStack stack(LOG_TAG);
加入库 libutilscallstack.so

三.C层

四.kernel层

  dump_stack();

五.实例

以下为从java层调用到C++层打开音频设备的完整流程：
函数传递的参数中包含了打开音频设备的卡号，和设备号。

//C++打开音频设备的函数调用， 从C到binder。
