问题描述

有没有办法在方式Android或Android中NDK知道哪些应用程序读取或在磁盘或存储设备写入数据？

Is there any way in way in Android or in Android NDK to know which application is reading or writing data on disk or device memory?

推荐答案

我不知道是否有这样做，但Linux将允许您列出进程/打开的文件/插座，你可以尝试抓住事物的SDK方式从那里。

I don't know if there is a SDK way of doing it but Linux will allow you to list processes/open files/sockets and you can try grabbing things from there.

先使用ps命令来获得进程的PID，请输入：

First use ps command to get PID of process, enter:

$ ps -aef | grep {process-name}
$ ps -aef | grep httpd

接下来通过这个PID为pfiles将命令

Next pass this PID to pfiles command,

$ pfiles {PID}
$ pfile 3533

这是怎么你列出了Firefox中使用的所有打开的文件...

This is how you'd list all open files used by firefox...

lsof -p `ps -C firefox -o pid=`

您可以使用System.exec（）来执行这些，但你也需要有root权限。这是一件好事，你必须要查看这方面的信息呢，我想...

You can use System.exec() to execute these, but you also need to have root access. Which is something you had to have to view that kind of information anyway I suppose...

这是我从Py2Cmod了

this is what i got from Py2Cmod

INIT.C

/* Generated by py2cmod

#include "Python.h"

static PyObject *ErrorObject;

/* ----------------------------------------------------- */

/* List of methods defined in the module */

static struct PyMethodDef iotop/__init___methods[] = {

{NULL,   (PyCFunction)NULL, 0, NULL}        /* sentinel */
};


/* Initialization function for the module (*must* be called initiotop/__init__) */

static char iotop/__init___module_documentation[] =  "";

void initiotop/__init__()
{
PyObject *m, *d;

/* Create the module and add the functions */
m = Py_InitModule4("iotop/__init__", iotop/__init___methods,
    iotop/__init___module_documentation,
    (PyObject*)NULL,PYTHON_API_VERSION);

/* Add some symbolic constants to the module */
d = PyModule_GetDict(m);
ErrorObject = PyString_FromString("iotop/__init__.error");
PyDict_SetItemString(d, "error", ErrorObject);

/* XXXX Add constants here */
PyDict_SetItemString(d, "__file__", PyString_FromString("iotop/__init__.py"));
PyDict_SetItemString(d, "__name__", PyString_FromString("iotop/__init__"));


/* Check for errors */
if (PyErr_Occurred())
    Py_FatalError("can't initialize module iotop/__init__");
}
