I used Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec("C:\\Android\\android-sdk-windows\\platform-tools\\adb.exe forward tcp:7777 tcp:7777"); for port forwarding in adb using android program. But it shows Exception :: java.io.IOException: Error running exec(). Commands: [C:\Android\android-sdk-windows\platform-tools\adb.exe, forward, tcp:7777, tcp:7777] Working Directory: null Environment: null what is the problem about the code?? Anyone can help me please.......... 来源: https://stackoverflow.com/questions/5789190/run-adb-command-using-android-program

问题 I'm trying to test my Android app on a new phone I've just purchased with Android 4.2. It runs every other app I test, and this particular app also works on other devices. When I try to run the code it's giving me the following errors: > 02-23 12:15:08.532: E/AndroidRuntime(5431): FATAL EXCEPTION: main 02-23 12:15:08.532: E/AndroidRuntime(5431): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.antiquity/com.example.antiquity.MainActivity}: java.lang

how to compile objective-c source code with clang in mingw64-x86 via apple libobjc.dll?

问题 i have a problem when compile objective-c source code on windows platform. of course compile objective-c source code on windows platform , we usually using gnustep environment(gcc objecitve-c compiler . gnustep libojc dynamic library . gnustep foundation framework ... and so on). but i want a clean environment try compiler objective-c , and use a different libobjc library. since mac os x 10.6 . apple move macosx system to x86 platform(no ppc support any more) , AND REWRITE system application

OSGi Declarative services filter references at runtime

时光总嘲笑我的痴心妄想 提交于 2019-12-07 21:42:59
问题 I've been trying some examples with OSGi Declarative Services (among other things, such as Blueprint) on Karaf. The problem I am trying to solve now, is how to get references to certain services at runtime (so annotations and/or XML are not really an option here) I will explain my use case: I am trying to design (so far only in my head, that's why I am still only experimenting with OSGi :) ) a system to control certain automation processes in industry. To communicate with devices, a special

Prove 3-Way Quicksort Big-O Bound

ε祈祈猫儿з 提交于 2019-12-07 19:39:27
For 3-way Quicksort (dual-pivot quicksort), how would I go about finding the Big-O bound? Could anyone show me how to derive it? There's a subtle difference between finding the complexity of an algorithm and proving it. To find the complexity of this algorithm, you can do as amit said in the other answer: you know that in average , you split your problem of size n into three smaller problems of size n/3 , so you will get, in è log_3(n)` steps in average, to problems of size 1. With experience, you will start getting the feeling of this approach and be able to deduce the complexity of

Swift Objective-C runtime class naming

巧了我就是萌 提交于 2019-12-07 18:28:27
问题 I've noticed that a Swift Class is renamed in objective-c runtime. So if I had a class in swift named ViewController and the name of my app was TestRuntime when I perform object_getClass(self) , self being ViewController , I would get this: _TtC11TestRuntime14ViewController . I've noticed this pattern or format: _TtC$$AppName$$ClassName , $ being a random number. I can't figure out where these numbers are coming from. If someone could shed some light on how swift names its classes in the

Need to crop+resize ~300000 files. Runtime = 4+ days. How can I speed up my bash script?

问题 I am working on creating a video timelapse. All the photos I took are .jpg images shot at 4:3 aspect ratio. 2592x1944 resolution. I want them all to be 16:9 at 1920x1080. I have written a little script to do this, but the process is not very fast. It took about 17 minutes for me to crop and resize 750 images. I have a total of about 300,000 to deal with, and will probably be doing then in batches of about 50,000. That is 18 hours 45 minutes per batch, and over 4.5 days of computing total. So

Can't run multiple-class program from command line using packages

问题 This is my first time posting -- I found similar issues but not anything concerning this issue directly. This sounds very simple but I'm not quite sure why this is occurring. My program runs beautifully in Eclipse but not from the command line. I have a few classes within a simpletree package. Here's BinaryTree.java : package simpletree; import java.io.*; public class BinaryTree implements Serializable { // Automatically generated UID private static final long serialVersionUID =

Template instantiation and function selection at runtime

心不动则不痛 提交于 2019-12-07 16:50:07
问题 I'm quite new to c++ and I'm trying to achieve something a bit tricky, for which I can't seem to find a satisfiable solution. Let's say I have these two functions: template <class T1, class T2> void foo(T1 param1, T2 param2){...}; template <class T1, class T2> void bar(T1 param1, T2 param2){...}; And at runtime, I want to select on of these two functions, and instantiate it with some template types obtained from a user input, say a char c . So I could do something like: double d; float f;
