问题 I have created a small program that will load particular website in webview. I want to keep watch on URL and if URL contains 'xxx' word then it should navigate to another page. for example if I set www.example.com. and I can now navigate to any page of www.example.com. If my Url contains word like 'xxx' then I want to exit that url and navigate to another url. Is is possible? and how? Thanks. //Here is my code. public class MainActivity extends Activity { private WebView Browser; @Override

.net runtime 2.0 instead of the newest version?

二次信任 提交于 2020-01-04 09:16:08
问题 On my computer I have installed .NET Framework 2.0 then later .NET Fratmeworkt 3.0. However recently i get an exception from one program saying "Event 1000, .NET Runtime 2.0 Error Reporting". I'm wondering, why this program is still using .NET Runtime 2.0 instead the new version. How could I check which version of .NET Runtime a specific program uses? Is possible to change it? 回答1: The ".NET runtime" actually means the "Common Language Runtime" (CLR), which has been version 2.0 for the .NET

Java Runtime exec() not working

问题 I try to execute a shell command via java like this if (Program.isPlatformLinux()) { exec = "/bin/bash -c xdg-open \"" + file.getAbsolutePath() + "\""; exec2 = "xdg-open \"" + file.getAbsolutePath() + "\""; System.out.println(exec); } else { //other code } Runtime.getRuntime().exec(exec); Runtime.getRuntime().exec(exec2); but nothing happens at all. When I execute this code it prints /bin/bash -c xdg-open "/home/user/Desktop/file.txt" in the console, but does not open the file. I have also

Get Current NT Header Data of running Process with C/C++

我是研究僧i 提交于 2020-01-04 07:47:05
问题 this is my first post and I am stuck here. I am currently working on my project and I have a problem, I am getting the baseaddress of my own module and read the process memory to get the IMAGE_DOS_HEADER in runtime then I continue adding e_lanew from the IMAGE_DOS_HEADER struct on the BaseAddress to get the IMAGE_NT_HEADER . Finally, I check the NT Signature if it's valid, and it seems to be. So reading the PE of my own process worked I guess ... I am trying to read TimeDateStamp and this

问题 This question already has answers here : How to get a list of current open windows/process with Java? (13 answers) Closed 4 months ago . I have the ID (pid) of this process. Now i want to find out when the process with this id has started. Note1: The process is not a java thread. Note2: JNA Solutions would also be welcome From my java context i want to get this information. How can it be done? UPDATE: see Note2. 回答1: On linux (I am running Ubuntu 14) public class SO { public static void main

android ART hook

喜欢而已 提交于 2020-01-04 05:36:12
0x00 前言 之前一直都是在Dalvik 虚拟机上在折腾,从Android 4.4开始开始引入ART,到5.0已经成为默认选择。而且最近看到阿里开源的 Dexposed 框架,已经提供了对于android art 模式下的 hook 支持,所以对照着android art 部分的源码和之前 liang 大牛放出了hook代码研究了一下ART模式下的hook原理,做个简单的整理。关于android ART 更详尽的部分 可以阅读csdn的博客专栏《老罗的android之旅》。 Android运行时ART执行类方法的过程分析 Android运行时ART加载类和方法的过程分析 Android运行时ART加载OAT文件的过程分析 0x01 ART ART是Android平台上的新一代运行时,用来代替dalvik。它主要采用了AOT(Ahead Of Time)的方法,在apk安装的时候将dalvikbytecode一次性编译成arm本地指令(但是这种AOT与c语言等还是有本质不同的,还是需要虚拟机的环境支持),这样在运行的时候就无需进行任何解释或编译便可直接执行。因为Dalvik执行的是Dex字节码,通过解释器执行。虽然Dalvik也会对频繁执行的代码进行jIT生成本地机器指令来执行,但毕竟在应用程序运行过程中将Dex字节码翻译成本地机器指令也会影响到应用程序本身的执行

第八章 Go并发 Go语言区别于其他语言的一大特点就是出色的并发性能,最重要的一个特性那就是 go 关键字。 并发场景: UI小姐姐一边开着PS软件,一边微信疯狂的和产品经理打字交流,后台还听着网易云音乐。。 双11当天。。大伙疯狂的访问淘宝网站 CPU从单核向多核发展,计算机程序不该是串行的,浪费资源 串行程序由于IO操作被阻塞,整个程序处于停滞状态,其他IO无关的任务无法执行 并发必要性: 充分利用CPU核心的优势,提高程序执行效率 实现并发的模型: 多进程,多进程是在操作系统层面并发的基本模式,进程间互不影响,但是开销最大,进程由内核管理。 多线程,属于系统层面的并发模式,也是用的最多的有效模式,大多数软件使用多线程,开销小于多进程。 基于回调的非阻塞/异步IO。此架构处于多线程模式的危机,高并发服务器下,多线程会消耗殆尽服务器的内存和CPU资源。而通过事件驱动的方式使用异步IO,尽可能少用线程,降低开销,Node.js就是如此实践,但是此模式编程复杂度较高。 协程,Coroutine是一种用户态线程,寄存于线程中,系统开销极小,可以有效提高线程任务并发性,使用方式简单,结构清晰,避免多线程的缺点。需要编程语言的支持,如不支持,需要用户自行实现调度器。 共享内存系统 是比较常用的并发模式,线程之间通信采用共享内存的方式,程序员需要加锁等操作避免死锁、资源竞争等问题。

Need an algorithm for a special array (linear field)

余生长醉 提交于 2020-01-04 05:16:14
问题 I have an Array (linear field) with pre sorted numbers [1, 2, 3, 4, 5, 6], but these arra y is shift to the right (k times), now its [5,6,1,2,3,4], k = 2 But I don´t know k. Only the array A. Now I need an Algorithm to find the max in A (with runtime O(logn)) I think its something with binary search, can anyone help me?? 回答1: The question can be re-stated in terms of finding the "point of discontinuity", i.e the index of the 6, 1 spot in the array. You can do it iteratively using an approach
