  • Android App crashing on one device only

    - by Daniel1402
    I am working on a new game that works perfectly on my test devices, 7-inch tablets and smartphones. But it crashes on my Galaxy Tab2 10-inch tablet with an Out of memory error. It always crashes when I start to play a second game! I have spent a full week checking the codes and I cannot figure out what is wrong. When I play from the menu screen, everything works fine. When I want to replay a game level from the level screen, the game will crash on the second launch. The level screen is made of 3 fragments, each with 32 buttons (4kB in size). I tried to keep only one fragment in memory with viewPager.setOffscreenPageLimit(1); but it does not solve the problem. Could someone stir me in some direction as to where to look for the potential problem? Why is the 10-inch tablet the only one to crash? Thanks.

  • How to deal with multiple screensizes + dynamic controls in Android?

    - by chobo2
    Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

  • iPad: How can I implement a scrolling timeline using a static image?

    - by BeachRunnerJoe
    I'm diving into iOS development and I'm building a simple timeline app using a static timeline image that I already have. The timeline image won't fit on the screen. The width of the image is about five times the width of the iPad screen, so I have to allow the user to scroll the image horizontally. Here's a mockup... For each item on the timeline, the user can tap it to receive a description at the bottom of the screen. My questions are... I was planning to use a UIScrollView with a PageControl at the bottom. Can a UIScrollView hold a single view that holds the entire timeline image or do I have to break the the timeline image up into multiple views? Are there any performance issues I need to consider when implementing this with a UIScrolLView, using a static image? Are there other approaches to implementing this scrollable timeline that I should consider other than using a UIScrollView? Thanks so much in advance for your wisdom!

  • Manipulate DOM before it is shown to the user?

    - by user246114
    Hi, I'm not too familiar with javascript, is there a way to manipulate the DOM before the page is displayed to the user? I'm using GWT which makes you create the page elements via javascript. This is kind of convenient, but it appears that all the javascript code is executed after the page is first shown to the user. This has the effect of showing the page as a blank white screen, then all the UI elements popping onto screen. The effect is really apparent when switching between pages. If I were using php or jsp, it looks like the page ui elements are already prerendered and the browser won't show a blank white screen before display. So is there any hook in javascript where we can manipulate the DOM before the browser clears out the contents of the last page shown? Thanks

  • How to get into android phone without having to press any buttons

    - by user2961092
    I'm not a programmer, so I'm not sure what I'd needed to answer my question. I'm wondering if it's possible to program a way to half wake your cell phone screen without having to press any buttons or using the sensors. Like I've found you can do on the blackberry z10, you have an option to wake the screen by swiping up from a locked screen. I love android and will use it regardless, but I had to use a z10 for work for a while and stumbled upon that feature. It would be fantastic to have that feature with Android as hitting a power button can get annoying. Thanks in advance

  • php exec and shell_exec not working

    - by chris
    I want to run an exe file on my server and return the output to the browser screen. The exe file takes a input file and then returns data on the screen. Why is this code not working? $output = shell_exec('myprogram < INP.DAT'); echo "<pre>" . var_export($output, TRUE) ."</pre>\\n"; It displays "NULL" on the browser screen. I have also tried exec(). There it returns "Array()".

  • How can I add a character and enemies to a game that uses Parallax Scrolling? [on hold]

    - by Homer_Simpson
    I use the following code to create Parallax Scrolling: http://www.david-gouveia.com/portfolio/2d-camera-with-parallax-scrolling-in-xna/ Parallax Scrolling is working but I don't know how to add the player and the enemies. I tried to add a player class to the existing code, but if the player moves, then the camera isn't pointing at the player. The player leaves the camera viewport after a few seconds. I use the following code(as described in the tutorial), but it's not working: // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); What can I do so that the player is always the center of the camera? How should I add the character and the enemies to the game? Should I create a layer for the character and the enemies? For example: new Layer(_camera) { Parallax = new Vector2(0.9f, 1.0f) } At the moment, I don't use a layer for the player and I don't have implemented the enemies because I don't know how to do that. My player class: public class Player { Texture2D Playertex; public Vector2 Playerposition = new Vector2(400, 240); private Game1 game1; public Player(Game1 game) { game1 = game; } public void Load(ContentManager content) { Playertex = content.Load<Texture2D>("8bitmario"); TouchPanel.EnabledGestures = GestureType.HorizontalDrag; } public void Update(GameTime gameTime) { while (TouchPanel.IsGestureAvailable) { GestureSample gs = TouchPanel.ReadGesture(); switch (gs.GestureType) { case GestureType.HorizontalDrag: Playerposition.X += 3f; break; } } } public void Render(SpriteBatch batch) { batch.Draw(Playertex, new Vector2(Playerposition.X - Playertex.Width / 2, Playerposition.Y - Playertex.Height / 2), Color.White); } } In Game1, I update the player and camera class: protected override void Update(GameTime gameTime) { // Updates my character's position player.Update(gameTime); // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); foreach (Layer layer in _layers) layer.Draw(spriteBatch); spriteBatch.Begin(SpriteSortMode.Deferred, null, null, null, null, null, _camera.GetViewMatrix(new Vector2(0.0f, 0.0f))); player.Render(spriteBatch); spriteBatch.End(); base.Draw(gameTime); }

  • Java: Using multiple Threads to paint simultaniously on a JPanel

    - by user347217
    I have a JPanel on which I wish to have several threads painting "animations" on. An "animation" consists of a JLabel with an ImageIcon on it, which is being moved from one area of the screen to another area. Now, problem is - I want several such animations to be portrayed on screen by those threads mentioned. Problem is - the JPanel's "paint()" method can only be trigged by one thread at a time - causing the animations to execute serially, instead of in a parallel way. Any idea how to have several such animations on screen at the same time?

  • How can I get my app ready for the iPhone 5

    - by RazorSharp
    Apple just announced the iPhone 5 with a 4 inch screen and a 16:9 aspect ratio. Of course, they only give developers two weeks to scramble to update their apps without being able to test. I'd like to update my app for the iPhone 5's new big screen, but there's nothing on Apple's developer site about the iPhone 5 or making your apps ready for a larger screen. It would be a pain to have to write my own logic for testing whether the device is an iPhone 5 and then displaying a custom storyboard file for it. Does anyone know how the new sizing works or if there are any hidden Xcode for this?

  • Immediately starting a new activity from an activity

    - by HowsItStack
    When I was originally learning about Android a few months ago I swear I read something about a way to immediately launch an activity when starting a task. I am curious about this now because I need to display an intro screen on launch but I don't want the intro screen to be the root activity. Does anyone know if there is something like this and if not what is the best way to handle an intro screen? I tried googling for a few hours to find it but can't for the life of me. Thanks for the help.

  • What options I have to show a sentence parts with different color?

    - by Pentium10
    I have a longer sentence 200 characters. I need to show on the screen having parts of them in different color, like highlighting search results, each with different color. The text should auto wrap with screen width, and have no break sections between parts. I meant with this that I can put sections on a new line. They will have to continue the previous section, only wrap when the screen is off. The best would be an EditText, as I need to allow editing also, but I am wondering I am able to change the color of various sentence parts, or just as a whole. What do you think, with what UI elements can I achieve this view?

  • How to run multiple instances of Tor?

    - by Ed
    I'm trying to set up a special proxy server (running Windows). It will have several instances of Privoxy and Tor running and my app will choose which Privoxy instance to send HTTP requests to depending on the load. Privoxy will then forward them to Tor. I'm using srvany.exe to create the services. At the moment I'm running 3 Privoxy and 3 Tor services (I copied the binaries to different folders). Each Privoxy service is listening to its own port (8118, 8119, 8120). I can see them listening in a port scanner. This is the application path (for srvany in registry) for the 1st service: C:\Anonymiser\Privoxy 01\privoxy.exe --service I've also configured the Tor services to listen to different ports (9050, 9052, 9054). This is the application path for the 1st service: C:\Anonymiser\Tor 01\tor.exe -f "C:\Anonymiser\Tor 01\torrc" The problem is, when I start the Tor services, only the first service I start is listening to its port. The others aren't listening. They listen if I run them separately. Any ideas what could be wrong? How can I make all 3 services listen on their assigned ports? This is one of my Privoxy configs: confdir . logdir . logfile privoxy.log debug 1 # show each GET/POST/CONNECT request debug 4096 # Startup banner and warnings debug 8192 # Errors - we highly recommended enabling this listen-address localhost:8118 toggle 0 enable-remote-toggle 0 enable-remote-http-toggle 0 enable-edit-actions 1 buffer-limit 4096 forwarded-connect-retries 0 forward-socks4a / localhost:9050 . This is one of my Tor configs: ControlPort 9051 Log notice stdout SocksListenAddress localhost SocksPort 9050 EDIT: Found a workaround. The Tor binary wants a lock on a file in the AppData folder. Because all of them want a lock on the same file, only the first one I start will be working. The workaround is to run each Tor instance under a different account. Not the best solution, but it works.

  • How to restrict file system when logged into terminal services

    - by pghcpa
    What I need to accomplish: With one login, when user is physically in the building I need them to see everything. When they are using terminal services with same login they should not be able to see the file system on the network. I can lock down the PC running terminal services as that is its only use. Details: Windows/2003 Server with terminal services. One login for a user (e.g., johndoe). When johndoe logs into the network at his desk in the office, he can see the network files according to group policy. When johndoe logs into terminal services from outside the building, we do not want to allow him see the network. Using 2x to do a published app, but that app has a "feature" that allows user to see network. Published application on termina services (only) is a document management system that is tied to windows login, so I can't give them two logins. With one login, when they are in the building I need them to see everything. When they are using terminal services they should not be able to see the network. I can lock down the PC running terminal services as that is its only use.

  • WebDAV through Apache2 permissions/missing files

    - by Strifariz
    I have a WebDAV setup on Apache2 on a server running Debian 5.0 (Lenny), which I am accessing through a mapped network drive under Windows 7. The setup appears to run fine, I receive no permission errors when copying a file to the share the first time, but the file never shows up in the directory (it's invisible, doing a ls -lha on the directory as root on the server also shows no files. When attempting to copy the file once more I am informed that the file already exists though, and I am asked if I wish to overwrite the file, when selecting "Yes" to this, I receive a permission error saying I'm not able to write to the folder. My logs aren't reporting any access violations of any kind, what could be the problem?

  • Flash plugin locks up Firefox, Chrome and Safari behind a corporate proxy, IE6 works fine

    - by Shevek
    At work I am forced by corporate policy to use IE6. Obviously this is not so good so I use FF for most of my browsing. However there is a problem once I have installed the Flash plug-in - FF locks up when trying to load Flash media. Looking at the status bar at the time of the lock up it appears this happens when the browser tries to get cross domain data. The Flash Active X plug-in in IE does not suffer this issue. I have tried it in a brand new profile in FF with Flash as the only plug in and it locks up. We have 2 different proxy servers and both exhibit the same problem. I have also tried Chrome and Safari and both lock up with the plug-in installed. So, has anyone else had this problem and solved it? Or, is there any way to disable cross domain data access in the flash plug-in? Or, is there any way to disable the "This site needs an additional plug-in" ribbon which appears when the plug-in is not installed. Many thanks!

  • Setting a time limit for a transaction in MySQL/InnoDB

    - by Trevor Burnham
    This sprang from this related question, where I wanted to know how to force two transactions to occur sequentially in a trivial case (where both are operating on only a single row). I got an answer—use SELECT ... FOR UPDATE as the first line of both transactions—but this leads to a problem: If the first transaction is never committed or rolled back, then the second transaction will be blocked indefinitely. The innodb_lock_wait_timeout variable sets the number of seconds after which the client trying to make the second transaction would be told "Sorry, try again"... but as far as I can tell, they'd be trying again until the next server reboot. So: Surely there must be a way to force a ROLLBACK if a transaction is taking forever? Must I resort to using a daemon to kill such transactions, and if so, what would such a daemon look like? If a connection is killed by wait_timeout or interactive_timeout mid-transaction, is the transaction rolled back? Is there a way to test this from the console? Clarification: innodb_lock_wait_timeout sets the number of seconds that a transaction will wait for a lock to be released before giving up; what I want is a way of forcing a lock to be released. Update: Here's a simple example that demonstrates why innodb_lock_wait_timeout is not sufficient to ensure that the second transaction is not blocked by the first: START TRANSACTION; SELECT SLEEP(55); COMMIT; With the default setting of innodb_lock_wait_timeout = 50, this transaction completes without errors after 55 seconds. And if you add an UPDATE before the SLEEP line, then initiate a second transaction from another client that tries to SELECT ... FOR UPDATE the same row, it's the second transaction that times out, not the one that fell asleep. What I'm looking for is a way to force an end to this transaction's restful slumber.

  • Weird .#filename files on remote ssh-connected systems after mcedit

    - by etranger
    I'm using MacFusion sshfs in combination with Midnight Commander, and when I edit remote text files with mcedit, weird symlinks are created on the remote system. $ ls -l .* lrwxr-xr-x 1 user group 34 Jun 27 01:54 .#filename.txt -> [email protected] where etranger is my local login name, and mbp is a hostname of my notebook running MacOS. symlinks can be removed by running remote rm command, but cannot be deleted on the mac-fuse mounted volume and thus pollutes the filesystem. I cannot figure what part of software is responsible for this, and how I could fix this, any help is appreciated. EDIT: This appears to be mcedit behavior as documented here: https://dev.openwrt.org/ticket/8245 Apparently, sshfs fails to remove symlink to the lock file for some reason (".#" in filename, perhaps), and it pollutes the filesystem. A quick workaround is possible, using another bug of Midnight Commander: editing (F4) the broken symlink effectively converts it to a missing lock file it was supposed to point to, and removes the symlink itself. The newly created file may then be deleted normally. EDIT 2: Unchecking "Follow symlink" in MacFusion apparently allows sshfs to remove dead symlinks, so the problem disappears completely.

  • How can I restore my original IME Romaji input settings?

    - by JOhn K
    the this one, Japanese IME on Windows: switch back to romaji input method (3) did not help. The problem seems the same. My Vista home premium version PC, I had been using Microsoft IME to use English and Japanese input using romaji henkan for a long time. One day, all of a sudden, first when I started up the PC, it has cap lock indicator ON. So, I press SHIFT key, CAP lock indicator is off!(This I have to do every morning.) Now when I want to type romaji input to change to Japanese, I switch EN English (United States) to "JP Japanese (Japan) and select input to hiragana input. It worked until that day. But now when I set to input romaji for hiragana as I used to do and start typing, then it shows Japanese hiragana directly on the display just as keyboard setting as Japanese ???109???????? as shown in Wikipedia JIS keyboard. And I cannot show hiragana as I wanted ( I can convert to Kanji OK) etc. by hitting space key. But its key board arrangement is what I never learned. Other thing I found is when I hit "`" key, it switches between hiragana and alphabet. When I see Control panel setting it is the same setting as I have seen. Please suggest me a solution to get the original setting for IME input mode as I used to do. John K.
