• AsyncTask never finishes when other tasks are running

  - by rebeccamaher

  In my app, I show a menu screen immediately to the user and then use an AsyncTask to load some data from disk. Loading takes about 3 seconds if that's all the app had to do. When the user hits a menu option and the data hasn't loaded yet, a "Please wait, loading" screen appears. I have two problems: I recently added ads to my app and have found this is making my app hang sometimes because the AsyncTask never finishes loading. What seems to be happening is that the ad banner (I'm using admob and this happens when adsense ads are shown which admob do occasionally) is using resources by playing a simple animation and the AsyncTask never gets a chance to finish. I want to play a simple looping animation (e.g. making a view rotate) on my menu screen and this makes the AsyncTask take about 5 times longer to finish which renders the background loading pointless. How can I avoid situations where my background data never finishes loading or has such a low priority it takes a long time? I can't seem to find a way to increase the priority of an AsyncTask.

• How to draw a part of a window into a memory device context?

  - by Nell

  I'm using simple statements to keep it, er, simple: The screen goes from 0, 0 to 1000, 1000 (screen coordinates). A window goes from 100, 100 to 900, 900 (screen coordinates). I have a memory device context that goes from 0, 0 to 200, 200 (logical coordinates). I need to send a WM_PRINT message to the window. I can pass the device context to the window via WM_PRINT, but I cannot pass which part of its window it should draw into the device context. Is there some way to alter the device context that will result in the window drawing a specific part of itself into the device context (say, its bottom right portion from 700, 700 to 900, 900)? (This is all under plain old GDI and in C or C++. Any solution must be too.) Please note: This problem is part of a larger solution in which the device context size is fixed and speed is crucial, so I cannot draw the window in full into a separate device context and blit the part I want from the resultant full bitmap into my device context.

• Android lifecycle: Fill in data in activity in onStart() or onResume()?

  - by pjv

  Should you get data via a cursor and fill in the data on the screen, such as setting the window title, in onStart() or onResume()? onStart() would seem the logical place because after onStart() the Activity can already be displayed, albeit in the background. Notably I was having a problem with a managed dialog that made me rethink this. If the user rotates the screen while the dialog is still open, onCreateDialog() and onPrepareDialog() are called between onStart() and onResume(). If the dialog needs to be based on the data you need to have the data before onResume(). If I'm correct about onStart() then why does the Notepad example give a bad example by doing it in onResume()? See http://developer.android.com/resources/samples/NotePad/src/com/example/android/notepad/NoteEditor.html NoteEditor.java line 176 (title = mCursor.getString...). Also, what if my Activity launches another Actvity/Dialog that changes the data my cursor is tracking. Even in the simplest case, does that mean that I have to manually update my previous screen (a listener for a dialog in the main activity), or alternatively that I have to register a ContentObserver, since I'm no longer updating the data in onResume() (though I could update it twice of course)? I know it's a basic question but the dialog only recently, to my surprise, made me realize this.

• How to determine if the camera button is half pressed

  - by Matthew

  I am creating a small test camera application, and I would like to be able to implement a feature that allows focus text bars to be present on the screen while the hardware camera button is pressed half way down. I created a camera_ButtonHalfPress event to perform the focus action, but I am unsure of how to toggle the text bars I would like to show on the screen accordingly. Essentially, my goal would be to show the text bars while the camera button is pressed half way down, and then remove them if the button is pressed all the way or the button is released before being pressed all the way down. The button being released is the part I am having trouble with. What I have is as follows: MainPage.xaml.cs private void camera_ButtonHalfPress(object sender, EventArgs e) { //camera.Focus(); // Show the focus brackets. focusBrackets.Visibility = Visibility.Visible; } } private void camera_ButtonFullPress(object sender, EventArgs e) { // Hide the focus brackets. focusBrackets.Visibility = Visibility.Collapsed; camera.CaptureImage(); } } Currently, if the the user decides to release the camera button before it is pressed all the way, the focus brackets persist on the screen. How might I fix this issue?

• How to re-enable the idle timer in ios once it has been disabled (to allow the display to sleep again)?

  - by lindon fox

  I have figured out how to stop an iOS device from going to sleep (see below), but I am having troubles undoing that setting. According to the Apple Documentation, it should just be changing the value of the idleTimerDisabled property. But when I test this, it does not work. This is how I am initially stopping the device from going to sleep: //need to switch off and on for it to work initially [UIApplication sharedApplication].idleTimerDisabled = NO; [UIApplication sharedApplication].idleTimerDisabled = YES; I would have thought that the following would do the trick: [UIApplication sharedApplication].idleTimerDisabled = NO; From the Apple Documentation: The default value of this property is NO. When most applications have no touches as user input for a short period, the system puts the device into a "sleep” state where the screen dims. This is done for the purposes of conserving power. However, applications that don't have user input except for the accelerometer—games, for instance—can, by setting this property to YES, disable the “idle timer” to avert system sleep. Important: You should set this property only if necessary and should be sure to reset it to NO when the need no longer exists. Most applications should let the system turn off the screen when the idle timer elapses. This includes audio applications. With appropriate use of Audio Session Services, playback and recording proceed uninterrupted when the screen turns off. The only applications that should disable the idle timer are mapping applications, games, or similar programs with sporadic user interaction. Has anyone come across this problem? I am testing on iOS6 and iOS5. Thanks in advance.

• how can I store the current status of the game in cocos2d ?

  - by srikanth rongali

  I am writing a shooting game in cocos2d. And each enemy enters the screen after the current one is dead. I have stores the enemies and their properties in plist. I need to save the current state of the game. If any phone call comes the game should be started from the current state. So, I usedNsUserDefaults in this way, - (void) applicationDidFinishLaunching:(UIApplication*)application { ... NSUserDefaults *myDefaultOptions = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; //tempCount4 is the current Enemy number. It was declared in another class. I am using extern and using the value here. tempCount4 = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; } - (void)applicationWillTerminate:(UIApplication *)application { [[CCDirector sharedDirector] end]; [myDefaultOptions setObject:tempCount4 forKey:@"enemyNumber"]; } The control is not entering in to the (void)applicationWillTerminate:(UIApplication *)application when I pressed the Home button. And when I touched the game icon on the screen the game is running from first screen and in log (terminal )it is not showing any values. And what should I store to resume my game from stored state. Can you explain where I was wrong ? Thank You.

• jQueryUI dialog width

  - by user35295

  Fiddle Full Screen Example I use jQuery dialog to open tables. Some of them have a large amount of text and they tend to be too long and go way off the screen. How can I make the dialog wider if the table is too long like the first one in the fiddle? I've tried width:'auto' but it seems to just occupy the entire screen. HTML: <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> Javascript: $(document).ready(function(){ $('.label').each(function() { var dialogopen = $(this).next(".dialog"); dialogopen.dialog({width:'auto',autoOpen: false,modal: true, open: function(){ jQuery('.ui-widget-overlay').bind('click',function(){ dialogopen.dialog('close'); }) } }); $(this).click(function(){ dialogopen.dialog('open'); return false; } ); }); });

• On android how would I go about creating a prompt for an app that requires a user to enter a username before fully launching the app?

  - by racl101

  I'll preface this with I'm really new to working on Android. So I have to work on an existing app and create a screen that prompts the user for a username if one isn't entered then it won't launch the currently existing main activity (i.e. it won't fully launch the app. Instead it will just sit on that screen until a username is entered.) I suppose that it's tantamount to a web app login page in that it will not let a user past that page if the user is not authenticated and authorized. However, there's no authentication nor authorization in this app. Instead, on first run a user must simply register with a username and that username gets saved to the database and for any subsequent runs the app's main activity will just start because a user has registered to that phone. In fact, the app will not prompt the user for their name again unless the app gets deleted with all its data and reinstalled again. This implicitly means that I have to save the user's name in the database or some other kind of storage. So I was wondering what would be the best way of doing this in an app with an existing main activity? Should I try to accomplish this on that existing main activity or create a new activity to display this prompt screen and, in effect, block the main activity from running until the user enters their name? Any tutorials or links would be helpful and thank you in advance for any help.

• Trouble getting QMainWindow to scroll

  - by random

  A minimal example: class MainWindow(QtGui.QMainWindow): def __init__(self, parent = None): QtGui.QMainWindow.__init__(self, parent) winWidth = 683 winHeight = 784 screen = QtGui.QDesktopWidget().availableGeometry() screenCenterX = (screen.width() - winWidth) / 2 screenCenterY = (screen.height() - winHeight) / 2 self.setGeometry(screenCenterX, screenCenterY, winWidth, winHeight) layout = QtGui.QVBoxLayout() layout.addWidget(FormA()) mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) FormA is a QFrame with a VBoxLayout that can expand to an arbitrary number of entries. In the code posted above, if the entries in the forms can't fit in the window then the window itself grows. I'd prefer for the window to become scrollable. I've also tried the following... replacing mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) with mainWidget = QtGui.QScrollArea() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) results in the forms and entries shrinking if they can't fit in the window. Replacing it with mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) scrollWidget = QtGui.QScrollArea() scrollWidget.setWidget(mainWidget) self.setCentralWidget(scrollWidget) results in the mainwidget (composed of the forms) being scrunched in the top left corner of the window, leaving large blank areas on the right and bottom of it, and still isn't scrollable. I can't set a limit on the size of the window because I wish for it to be resizable. How can I make this window scrollable?

• Disable home button in android toddler app?

  - by cmerrell

  I've developed and app that is a slide show of pictures which each play a sound when you tap them. It's like a picture book for ages 2-4. The problem is, since android won't let you capture a home button press and essentially disable it, when parents give the phone to their child to play with unattended (brave parent), the child can inadvertenly exit the app and then make calls or otherwise tweak the phone. There are two other apps that currently have a psuedo fix for this issue. The apps are Toddler Lock and ToddlePhone. I've tried contacting the developers of these apps for some guidance but they haven't been willing to disclose anything, which if fine, but does anyone here have any suggestions? It looks like both of those other apps are acting like a home screen replacement app. When you enable the "childproof mode" on those apps the user is prompted to chose and app for the action and the choices are "Launcher, LauncherPro, etc." plus the toddler app. You then have to make the toddler app the default and voila, the phone is "locked" and can only be "unlocked" using a key combination or touching the four corners of the screen, etc. when you "unlock" the phone. your normal home screen app default restored. You don't even have to make the toddler app the default the next time you enable the "childproof mode". I have read that these two apps have problems with Samsung phones and they can cause an an infinite crash-and-restart-loop that requires a factory reset to fix. Obviously this is not the ideal solution to the problem but it looks like the only one availiable at this point. Does anyone have any ideas on how to implement a "childproof mode"?

• Trying to create a group of button sprites

  - by user1449653

  Good day, I have like 15 images I need to be buttons. I have buttons working with a Box() (Box - looks like this) class Box(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.Surface((35, 30)) self.image = self.image.convert() self.image.fill((255, 0, 0)) self.rect = self.image.get_rect() self.rect.centerx = 25 self.rect.centery = 505 self.dx = 10 self.dy = 10 I am trying to make the buttons work with image sprites. So I attempted to copy the class style of the box and do the same for my Icons.. code looks like this... class Icons(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/airbrushIC.gif").convert() self.rect = self.image.get_rect() self.rect.x = 25 self.rect.y = 550 the code in the main() rect = image.get_rect() rect.x = 25 rect.y = 550 ic1 = Icons((screen.get_rect().x, screen.get_rect().y)) screen.blit(ic1.image, ic1.rect) pygame.display.update() This code produces a positional (accepts 1 argument but 2 are there) error or an image is not referenced error (inside the Icon class). I'm unsure if this is the right way to go about this anyways.. I know for sure that I need to load all the images (as sprites)... store them in an array... and then have my mouse check if it is clicking one of the items in the array using a for loop. Thanks. EDIT QUESTION 2: class Icons(pygame.sprite.Sprite): def init(self, *args): pygame.sprite.Sprite.init(self, *args) self.image = pygame.image.load("images/airbrushIC.gif").convert() self.rect = self.image.get_rect() ic1 = self.image self.rect.x = 10 self.rect.y = 490 self.image = pygame.image.load("images/fillIC.gif").convert() self.rect = self.image.get_rect() ic2 = self.image self.rect.x = 10 self.rect.y = 540 Thanks to your help I got the Icons class loading ONE image. Its not loading both. Obviously because its being overwritten by the second one. It seems that "class" for this purpose isn't what I need. Which begs the question how I make sprites outside of a class.. If there is a way to make the class work please let me know.

• Tips on refactoring an Android prototype

  - by Brad

  I have an Android project I've inherited from another developer. The original code was hacked together using a single View and a single Activity. The view class has a State variable that is switched on during input and rendering. Each "screen" is a single bitmap rendered directly onto the screen. There are no layouts used at all. To make things even worse each variable in both the View and Activity classes were all declared public static and would access each other frequently. I've reworked the code so it is now somewhat manageable, but it's still in those original two classes. This is my first decently sized Android app so I'm not completely sure where to go next. From the looks of things, each "screen" should have its own View and Activity. Is this the general practice? If so I need some way to share data between the separate Activities. I've read suggestions to use a Singleton class that holds generic data. Is there any other ways that are more built into the Android framework? Thanks in advance.

• Converting a view to Bitmap without displaying it in Android?

  - by sunil

  Hi, I will try to explain what exactly I need to do. I have 3 separate screens say A,B,C. There is another screen called say HomeScreen where all the 3 screens bitmap should be displayed in Gallery view and the user can select in which view does he wants to go. I have been able to get the Bitmaps of all the 3 screens and display it in Gallery view by placing all the code in HomeScreen Activity only. Now, this has complicated the code a lot and I will like to simplify it. So, can I call another Activity from HomeScreen and do not display it and just get the Bitmap of that screen. For example, say I just call HomeScreen and it calls Activity A,B,C and none of the Activities from A,B,C are displayed. It just gives the Bitmap of that screen by getDrawingCache(). And then we can display those bitmaps in Gallery view in HomeScreen. I hope I have explained the problem very clearly. Please let me know if this is actually possible. Regards Sunil

• More than one JPanel in a Frame / having a brackground Image and another Layer with Components on the top

  I've got a JFrame with a JPanel in which there is a JLabel with an ImageIcon().

• State in OpenGL

  - by newprogrammer

  This is some simple code that draws to the screen. GLuint vbo; glGenBuffers(1, &vbo); glUseProgram(myProgram); glBindBuffer(GL_ARRAY_BUFFER, vbo); glEnableVertexAttribArray(0); glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0); //Fill up my VBO with vertex data glBufferData(GL_ARRAY_BUFFER, sizeof(vertexes), &vertexes, GL_STATIC_DRAW); /*Draw to the screen*/ This works fine. However, I tried changing the order of some GL calls like so: GLuint vbo; glGenBuffers(1, &vbo); glUseProgram(myProgram); glEnableVertexAttribArray(0); glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0); //Now comes after the setting of the vertex attributes. glBindBuffer(GL_ARRAY_BUFFER, vbo); //Fill up my VBO with vertex data glBufferData(GL_ARRAY_BUFFER, sizeof(vertexes), &vertexes, GL_STATIC_DRAW); /*Draw to the screen*/ This crashes my program. Why does there need to be a VBO bound to GL_ARRAY_BUFFER while I'm just setting up vertex attributes? To me, what glVertexAttribPointer does is just set up the format of vertexes that OpenGL will eventually use to draw things. It is not specific to any VBO. Thus, if multiple VBOs wanted to use the same vertex format, you would not need to format the vertexes in the VBO again.

• Hide annoying VMware hint "To release input, press Ctrl+Alt"

  - by EMP

  I'm running VMWare Workstation 7 on Windows 7 x64. In the guest OS (also Windows 7 x64) I have VMWare Tools installed, but the VMWare Tools service is disabled. I run the VM in full screen mode and the VMWare toolbar at the top often displays this tooltip: To release input, press Ctrl+Alt This tooltip obscures a part of the VM (often the menu of a program I'm using) and it's annoying as hell. Going out of full screen mode and into it again gets rid of it, but only until I mouse over that toolbar and then it reappears! How do I get rid of it, once and for all? I tried adding hints.hideAll = "TRUE" to the .vmx file for the VM and to preferences.ini and neither of those helped.

• Implementing Scrolling Background in LibGDX game

  - by Vishal Kumar

  I am making a game in LibGDX. After working for whole a day..I could not come out with a solution on Scrolling background. My Screen width n height is 960 x 540. I have a png image of 1024 x 540. I want to scroll the background in such a way that it contuosly goes back with camera x-- as per camera I tried many alternatives... drawing the image twice ..did a lot of calculations and many others.... but finally end up with this dirty code if(bg_x2 >= - Assets.bg.getRegionWidth()) { //calculated it to position bg .. camera was initially at 15 bg_x2 = (16 -4*camera.position.x); bg_x1=bg_x2+Assets.bg.getRegionWidth(); } else{ bg_x1 = (16 -4*camera.position.x)%224; // this 16 is not proper //I think there can be other ways bg_x2=bg_x1+Assets.bg.getRegionWidth(); } //drawing twice batch.draw(Assets.bg, bg_x2, bg_y); batch.draw(Assets.bg, bg_x1, bg_y); The Simple idea is SCROLLING BACKGROUND WITH SIZE SOMEWHAT MORE THAN SCREEN SIZE SO THAT IT LOOK SMOOTH.

• pygame double buffering

  I am trying to use double buffering in pygame. What I'm trying to do is display a red then green screen, and switch from one to the other. Unfortunately, all I have is a black screen. I looked through many sites, but have been unable to find a solution. Any help would be appreciated. import pygame, sys from pygame.locals import * RED = (255, 0, 0) GREEN = ( 0, 255, 0) bob = 1 pygame.init() #DISPLAYSURF = pygame.display.set_mode((500, 400), 0, 32) DISPLAYSURF = pygame.display.set_mode((1920, 1080), pygame.OPENGL | pygame.DOUBLEBUF | pygame.HWSURFACE | pygame.FULLSCREEN) glClear(GL_COLOR_BUFFER_BIT) glMatrixMode(GL_MODELVIEW) glLoadIdentity() running = True while running: if bob==1: #pygame.draw.rect(DISPLAYSURF, RED, (0, 0, 1920, 1080)) #pygame.display.flip() glBegin(GL_QUADS) glColor3f(1.0, 0.0, 0.0) glVertex2f(-1.0, 1.0) glVertex2f(-1.0, -1.0) glVertex2f(1.0, -1.0) glVertex2f(1.0, 1.0) glEnd() pygame.dis bob = 0 else: #pygame.draw.rect(DISPLAYSURF, GREEN, (0, 0, 1920, 1080)) #pygame.display.flip() glBegin(GL_QUADS) glColor3f(0.0, 1.0, 0.0) glVertex2f(-1.0, 1.0) glVertex2f(-1.0, -1.0) glVertex2f(1.0, -1.0) glVertex2f(1.0, 1.0) glEnd() pygame.dis bob = 1 for event in pygame.event.get(): if event.type == pygame.QUIT: running = False elif event.type == KEYDOWN: if event.key == K_ESCAPE: running = False pygame.quit() sys.exit() I'm using Python 2.7 and my code need to be os independent. Thanks for your help.
