• Where should I report mistakes in Android documentation?

  - by Nick

  Hi all, This is my first post ever -- I love the Android SDK (been at it for a week), but I did notice a small typo in the official documentation that needs correcting. Not sure if this is where I post it, but on this page: http://developer.android.com/reference/android/os/CountDownTimer.html within the example source code, the source says "CountdownTimer" on line one when it should say "CountDownTimer" (notice the capitalization of the letter "D"). An easy fix for one with programming experience, but the code as written will not compile, which could be confusing for someone using this code for the first time. Is this where documentation bugs are submitted, and if not, where should I go to request the fix? Thanks all!

• Wrapping C/C++ inside Java

  - by Ashwin

  I develop applications/programs in C/C++. I am more versed in these two languages and love being a C++ developer. I am wondering how to create a Java program that contains all my C++ code. I mean, I would like to wrap all my C++ code (that is already developed) inside Java class. But clueless how to do it. Please post your responses or methods/steps on integrating C++ inside Java. (using JNI is the way, but I could not figure it out on www how to use it) FYI, I use Eclipse IDE to develop. How and what packages should I include in my project workspace?

• Question about software that tracks divs better than notepad++

  - by Jeff

  I recently got hired as a web developer, and the project that I am overseeing has a formatting issue on one of the pages because one of the divs is out of whack. It is a fairly complex page with quite a bit of php, and from what I can gather, I am missing a </div> tag somewhere, and accordingly everything is messed up. I am currently using notepad++, which is decent at lining up divs, meaning that if you click on the opening div tag, it will highlight purple and also highlight the closing one. But it seems as though if you have div tags that span several lines (hundreds) it won't work. Has anyone else run into a similar situation? Is there a better editor I could be using that would do a better job of helping me with my div issue? Or do I have to go through and line up the divs 1 by 1? (there are like over 100). Please let me know!! Thanks

• Technologies used in EMBL

  - by Sergej Andrejev

  My fried suggest I try to apply for a job at EMBL. I'm not bioinformatic in any way, but my friend (who by the way is a biologist working at EMBL) insists that I could adapt to the new environment as long as I have a interest in subject and am generally good at learning new things. But here is a catch. For the last 4 years I've been working with .Net and other Microsoft technologies which I enjoy even more lately. Now, from googling I couldn't find whether it will be possible for me to stick with .Net because it was all perl, java, linux and so on. Is there anybody who could prove whether there is at least minor opportunity for a .Net developer to at least partly develop with C#?

• What are the possible tags of "global" tag in Magento "config.xml" file?

  - by Knowledge Craving

  Can someone professional experienced Magento developer tell me how to accomplish the following in Magento? I want to know what are the possible tags that can fit in the "global" tag of the "config.xml" page of every module's etc folder? I have tried searching for this answer at many places in Internet but in vain. Please provide the full details along with it, because I want at least the users accessing this website find it useful enough, instead of scratching their heads. I really want a detailed explanation, because every newbie like me gets totally confused at this point. From what I know till now, is that in this page, you can set routers, rewrites, cron jobs, admin html, front-end html and many more. But without any strong concepts. So please I want that strong fundamental concept with a detailed explanation about it.

• Looking for a good course/book/resource on modern databases

  - by spanky

  This is slightly embarrassing. I'm a professional developer working at one of the big tech companies and I've never used a database. I've got an idea for a website I want to build as a learning experience and possibly as a business, but I don't have the faintest idea what database to use, let alone how to fix/debug the database when I run into problems. I'm looking for a course, a website, a book, etc., that will give me an overview of modern database technology (SQL vs. NOSQL vs. relational vs. non-relational (I only have a vague idea what these even mean)). I'm starting by googling/wikipediaing all of these terms, but if there are better, comprehensive resources available that I should be aware of, I'd love to hear about them.

• WeakHashMap iteration and garbage collection

  - by Shamik

  I am using a WeaekHashMap to implement a Cache. I am wondering if I am iterating over the keys of this map, and at the same time garbage collector is actively removing keys from this map, would I receive a ConcurrentModificationException ? I do not think so, because as far as I understand, concurrentmodificationexception happens because of bugs in the application code where the developer forgot to understand that the same map is shared/used by other threads and in this case, it should not happen. But wondering how would JVM handle this when WeakHashMap is not synchronized ?

• Using TFS source control - how to remove files

  - by arame3333

  I am a lone developer, and I am now using TFS 2010, having until recently used VSS. I have not found it easy to get any books for beginners to help me use this. So I have now got my project in source control. But when I check in I get references to a number of files that I no longer use. How do I remove files from the TFS Source Control repository? So in the example below you can see lots of files from different projects that I do not want to see.

• Software buttons in the android 4.2 emulator not showing up (tablet)

  - by The_Unknown

  I'm getting crazy right now. I just installed the latest android adt bundle from http://developer.android.com/sdk/index.html. It's version v21.0.0. Now I wanted to test my tablet app (designed for 10.1" xlarge mdpi) in the emulator, but I cannot get any software buttons for home/back/... Here's my device configuration. This config is afterwards assigned to the avd. http://i.stack.imgur.com/Q7xvP.png Hardware-buttons don't work as well (you cannot set hardware buttons in a tablet-like emulator). The target api is level 15 (android 4.0.3). I searched stackoverflow, but didn't find any help concerning the latest version of android. Since time's running away a little, any quick help would be great! Thanks in advance. Bye The_Unknown

• How to read output of android process command

  - by kevdliu

  I am trying to get the output of android shell command 'getprop' with java since getprop() always returns null no matter what. I tried this from developer.android.com: Process process = null; try { process = new ProcessBuilder() .command("/system/bin/getprop", "build.version") .redirectErrorStream(true) .start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } InputStream in = process.getInputStream(); //String prop = in.toString(); System.out.println(in); process.destroy(); However what is printed is not the output but a bunch of characters and numbers (dont have the exact output right now). How can i get the output of the process? Thanks!

• How to open a new screen with additional parameters?

  - by Solo

  I've read through the FAQ of Android Dev Guid (http://developer.android.com/guide/appendix/faq/commontasks.html#opennewscreen) but I'm not sure how can I open a new screen with additional parameters passed into it. Let's say I'm going to open screen2, with a variable indicating the current user name so that I could greet the users. Is it possible? Intent i; i = new Intent(this, screen2.class); //How to pass variable to screen2? startActivity(i);

• iOS app private distribution and MDM

  - by Hippocrates

  We want to develop apps for a variety of separate clients for use on their iPads/iPhones. Right now we have a developer license and and provision UUIDs manually and distribute the app OTA via a web server. This limits us to 100 devices per license and leaves us paying for upkeep of the license. Some of our clients may also be interested in using an MDM software package. What is the best way for us to provision and push apps to many clients and more that 100 devices? Would each client need to pay for their own enterprise license? Any input is appreciated. Thanks.

• How much market shares OpenGL2.0 in iPhone os hardwares(iPhone/iPot Touch)

  - by Eonil

  I'm planning making a game for AppStore, so I'm studying GLES. But, GLES 1.1 and 2.0 APIs are different about handling in some features.(and limitations) I have not enough time to consider both of them, I have to choosing one. 2.0 is clearly better in developer's view, but I'm worry about it's market share. I wish most users moved on newer SGX based hardware, but in fact, I don't know. Does anybody have information about location of those hardware ratio data in iPhone OS supported hardwares? (iPhone/iPod touch, per GPU) Please let me know.

• Secure Webservice?

  - by cam

  I'm trying to create a secure webservice (that provides simple database data) with PHP that can be connected to through my Silverlight application. I don't know enough about PHP to be able to see another way to do this. The webservice should only be accessible through the client, and only with the proper username/password. The only two ways I can imagine to do this would be by passing the username/password hash via URL, or use a "hidden form" and do it via POST_. I'm just trying to get past this point, I'm the sole developer on this project and I'm just trying to get past this PHP webservice part so I can get back to being an application programmer :) Normally, I would learn PHP, but I'm on the clock, so I'm just looking for a point in the right direction on how to achieve this!

• SVN user guidelines

  - by Oliver Moran

  I have been tasked with writing a set of user guidelines for SVN for developers in my company. The guidelines are to be solely from a user perspective (e.g. commit comments, when to commit) and not from an administrative perspective (e.g. when to tag, how to structure). An administrative guideline will be written in a separate document. We are an app development house involved also in embedded development. So our developers range from HTML5 and Flash to Java and C. Some of our coding involves forking very large (millions of files) code bases. Other parts involve us engaging in ground-up development. Are there any best practices for use of SVN from a user (i.e. grunt developer) perspective?

• Hashing and salting values

  - by Avanst

  I am developing a small web app that internally authenticates users. Once the user is authenticated my web app then passes some information such as userID and Person's name to a third party web application. The third party developer is suggesting that we hash and salt the values. Forgive my ignorance, but what exactly does that mean? I am writing the app in Java. So what I am planning on doing is hashing the userID, Person's name, and some Math.random() value as the salt with Apache Commons Digest Utils SHA512 and passing that hashed string along with the userID and person's name. Is that the standard practice? I should be passing the third party the salt as well correct?

• SVN always getting errors when I commit (Subclipse)

  - by jax

  I have setup svn on my server and Subclipse at home. I am the only developer and am mainly using it for the backup and versioning features. Everytime I commit my changes I get eighter: Out Of date errors or Tree conflicts Sometimes I even delete files and they don't delete on svn, in a directory hierarchy only the very last item will delete so I have to delete each folder one at a time. How do I avoid these errors in the future? Update: Another problem I am having is that sometimes eclipse seems to sync with the server so that when I refactor a filename it goes off to the server and does something and makes me wait, which is annoying. And for clarity, this is a typical operation: I might change a filename, move a file to a different folder then change the contents of a file. I select the 'Team menu' and click 'commit'. Then I get all these errors above.

• How is the implicit segment register of a near pointer determined?

  - by Daniel Trebbien

  In section 4.3 of Intel 64® and IA-32 Architectures Software Developer's Manual. Volume 1: Basic Architecture, it says: A near pointer is a 32-bit offset ... within a segment. Near pointers are used for all memory references in a flat memory model or for references in a segmented model where the identity of the segment being accessed is implied. This leads me to wondering: how is the implied segment register determined? I know that (%eip) and displaced (%eip) (e.g. -4(%eip)) addresses use %cs by default, and that (%esp) and displaced (%esp) addresses use %ss, but what about (%eax), (%edx), (%edi), (%ebp) etc., and can the implicit segment register depend also on the instruction that the memory address operand appears in?

• C++ LoadLibrary() from the current path

  - by gillyb

  Hey, I'm a .net developer mostly, doing something small in C++ so im having a little trouble. I'm loading another C++ dll using hInst = LoadLibrary(TEXT("mydll.dll")); and I came to realize that this looks for the dll I'm trying to load in 'C:\' or in 'system32'. Can someone show me how to load the dll from the current directory (without knowing what the current directory is ahead of time) ?? I know I should be using something like GetFullPathName but I'm having a little trouble getting it to work on my own...

• how does selenium webdriver upload files to the browser?

  - by justspamjustin

  I am a javascript/java developer and I have been trying to figure out how the selenium webdriver automation framework uploads files from the file system. It is impossible to set a file input via javascript because it is a security violation. Yet somehow webdriver is able to do this with the following command: driver.setFileDetector(new LocalFileDetector()); WebElement upload = driver.findElement(By.id("myfile")); upload.sendKeys("/Users/sso/the/local/path/to/darkbulb.jpg"); driver.findElement(By.id("submit")).click(); So they are setting the value by sending keys to it? I don't get it. I have looked through the source code found here: http://code.google.com/p/selenium/source/checkout I am still not able to find where they do this. Edit: My question is not how to do this with selenium, but how did the selenium developers make this possible? How did they get around the security restrictions in javascript? How are they uploading the file?

• Problem with CFNetRegister

  - by xtrahotsauce

  I'm trying to work with CFNetServices by trying to start up and publish a service asynchronously. I'm trying to use the example code from here: http://developer.apple.com/mac/library/documentation/Networking/Conceptual/NSNetServiceProgGuide/Articles/CFNetServices.html#//apple_ref/doc/uid/30001276-SW3, but CFNetRegisterWithOptions always fails. (CFNetRegister is deprecated now). When I print out the error struct, it looks like this: (gdb) p error $1 = { domain = 10, error = -72004 } Which doesn't seem correct to me. Does anyone know what might be wrong? Thanks!

• Developing for Windows 6.5

  - by j-t-s

  Hi All I have just got a new company mobile and would like to begin developing apps for the HTC HD2 Mobile Phone. However, when I downloaded Microsoft Windows Phone Developer Tools, it pretty much said right at the end of installation that "Setup could not install correctly", and I clicked on "more", and it said "Silverlight 4.0 could not install correctly". So, the fact that Windows Phone Dev Tools couldn't install completely was because of this Silverlight 4 that couldn't install! Has anyone had the same problems, if so, how did you resolve this issue (if you did)? And... Is there another way to develop applications for mobile phones running the Windows Operating System other than XNA and Windows Dev Tools? Even better... Could it be done simply using the current Visual Studio Express Edition I already have? Thanks All
