  • Android Phonegap - TIMEOUT ERROR when trying to set a WebViewClient

    - by Spike777
    I'm working with Android and Phonegap, and at the moment I'm having trouble with one simple thing. I need to setup a webViewClient to the PhoneGap webView in order to capture the URL of a page finished and to work with that. This is the code: public class PhoneGapTest extends DroidGap { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); super.setBooleanProperty("loadInWebView", true); super.clearCache(); super.keepRunning = false; super.loadUrl("file:///android_asset/www/index.html"); super.appView.setWebViewClient(new WebViewClient(){ @Override public void onPageStarted(WebView view, String url, Bitmap bitmap) { Log.i("TEST", "onPageStarted: " + url); } @Override public void onPageFinished(WebView view, String url) { Log.i("TEST", "onPageFinished: " + url); } }); } That code doesn't seems to work, the page never loads and I get a TIMEOUT ERROR, but if I remove the "setWebViewClient" part the page loads perfectly. I saw that there is a class CordovaWebViewClient, do I have to use that instead of WebViewClient? I found this way on the web: this.appView.setWebViewClient(new CordovaWebViewClient(this){ @Override public boolean shouldOverrideUrlLoading(final WebView view, String url) { Log.i("BugTest", "shouldOverrideUrlLoading: " + url); return true; } @Override public void onPageStarted(WebView view, String url, Bitmap bitmap) { Log.i("TEST", "onPageStarted: " + url); } @Override public void onPageFinished(WebView view, String url) { Log.i("TEST", "onPageFinished: " + url); } @Override public void doUpdateVisitedHistory(WebView view, String url, boolean isReload){ } }); But that code isn't working either, I still got a TIMEOUT ERROR. I also saw that there is already a webVieClient member, but I don't if I have to use it and how. I'm working with Phonegap version 1.9.0 Thanks for reading Answer to Simon: This doesn't work either, I still receive a TIMEOUT ERROR, there is something wrong? public class MainActivity extends DroidGap { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); super.init(); super.appView.clearCache(true); super.appView.clearHistory(); this.appView.setWebViewClient(new CustomCordovaWebViewClient(this)); super.loadUrl("file:///android_asset/www/index.html"); } public class CustomCordovaWebViewClient extends CordovaWebViewClient { public CustomCordovaWebViewClient(DroidGap ctx) { super(ctx); } @Override public void onPageStarted(WebView view, String url, Bitmap bitmap) { Log.i("TEST", "onPageStarted: " + url); } @Override public void onPageFinished(WebView view, String url) { Log.i("TEST", "onPageFinished: " + url); } @Override public void doUpdateVisitedHistory(WebView view, String url, boolean isReload){ } @Override public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { } } }

  • C builder RAD 2010 RTL/VCL Application->Terminate() Function NOT TERMINATING THE APPLICATION

    - by ergey
    Hello, I have problem descriebed also here: http://www.delphigroups.info/3/9/106748.html I have tryed almost all forms of placing Application-Terminate() func everywhere in the code, following and not 'return 0', 'ExitProcess(0)', 'ExitThread(0)', exit(0). None working variant closes the app. Instead the code after Application-Terminate() statement is running. I have two or more threads in the app. I tryed calling terminate func in created after execution threads and in main thread. Also this is not related (as i can imagine) with CodeGuard / madExcept (i have turned it off and on, no effect). CodeGuard turning also did not do success. What i should do to terminate all the threads in c builder 2010 application and then terminate the process? Thank you.

  • Is writing to a socket an arbitrary limitation of the sendfile() syscall?

    - by Sufian
    Prelude sendfile() is an extremely useful syscall for two reasons: First, it's less code than a read()/write() (or recv()/send() if you prefer that jive) loop. Second, it's faster (less syscalls, implementation may copy between devices without buffer, etc...) than the aforementioned methods. Less code. More efficient. Awesome. In UNIX, everything is (mostly) a file. This is the ugly territory from the collision of platonic theory and real-world practice. I understand that sockets are fundamentally different than files residing on some device. I haven't dug through the sources of Linux/*BSD/Darwin/whatever OS implements sendfile() to know why this specific syscall is restricted to writing to sockets (specifically, streaming sockets). I just want to know... Question What is limiting sendfile() from allowing the destination file descriptor to be something besides a socket (like a disk file, or a pipe)?

  • Custom tool error: Command.proto:11:18: "Message2" is not defined.

    - by cornerback84
    I am using the latest version of protobuf-net with VS2008 integration. I have created 2 messages (Message1 and Message2), 1 message in 1 proto file. When I try to reference Message2 in Message1 the code generator tool gives me error "Message2" is not defined and won't generate the code file. The package for both messages is same. It look like that because of the integration of the tool with VS2008 it expects all the messages in same .proto file to compile. Currently I have to paste an empty message with same name in Message1.proto file, like this: message Message1 { optional Message2 message2 = 1; } message Message2 { } And then later on remove the declaration of class Message2 from Message1.cs. Are there any settings that I need to do so to avoid this error, or is providing an empty declaration the only way?

  • Creating a simple templated control. Having issues...

    - by Jimock
    Hi, I'm trying to create a really simple templated control. I've never done it before, but I know a lot of my controls I have created in the past would have greatly benefited if I included templating ability - so I'm learning now. The problem I have is that my template is outputted on the page but my property value is not. So all I get is the static text which I include in my template. I must be doing something correctly because the control doesn't cause any errors, so it knows my public property exists. (e.g. if I try to use Container.ThisDoesntExist it throws an exception). I'd appreciate some help on this. I may be just being a complete muppet and missing something. Online tutorials on simple templated server controls seem few and far between, so if you know of one I'd like to know about it. A cut down version of my code is below. Many Thanks, James Here is my code for the control: [ParseChildren(true)] public class TemplatedControl : Control, INamingContainer { private TemplatedControlContainer theContainer; [TemplateContainer(typeof(TemplatedControlContainer)), PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate ItemTemplate { get; set; } protected override void CreateChildControls() { Controls.Clear(); theContainer = new TemplatedControlContainer("Hello World"); this.ItemTemplate.InstantiateIn(theContainer); Controls.Add(theContainer); } } Here is my code for the container: [ToolboxItem(false)] public class TemplatedControlContainer : Control, INamingContainer { private string myString; public string MyString { get { return myString; } } internal TemplatedControlContainer(string mystr) { this.myString = mystr; } } Here is my mark up: <my:TemplatedControl runat="server"> <ItemTemplate> <div style="background-color: Black; color: White;"> Text Here: <%# Container.MyString %> </div> </ItemTemplate> </my:TemplatedControl>

  • Animating a font size change in a UITableView

    - by nickthedude
    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

  • decompress .gz file in batch

    - by kapildalwani
    I have 100 of .gz files which I need to de-compress. I have couple of questions a) I am using the code given at http://www.roseindia.net/java/beginners/JavaUncompress.shtml to decompress the .gz file. Its working fine. Quest:- is there a way to get the file name of the zipped file. I know that Zip class of Java gives of enumeration of entery file to work upon. This can give me the filename, size etc stored in .zip file. But, do we have the same for .gz files or does the file name is same as filename.gz with .gz removed. b) is there another elegant way to decompress .gz file by calling the utility function in the java code. Like calling 7-zip application from your java class. Then, I don't have to worry about input/output stream. Thanks in advance. Kapil

  • Help with iphone dev - beyond bounds error

    - by dusk
    I'm just learning iphone development, so please forgive me for what is probably a beginner error. I've searched around and haven't found anything specific to my problem, so hopefully it is an easy fix. The book has examples of building a table from data hard coded via an array. Unfortunately it never really tells you how to get data from a URL, so I've had to look that up and that is where my problems show up. When I debug in xcode, it seems like the count is correct, so I don't understand why it is going out of bounds? This is the error message: 2010-05-03 12:50:42.705 Simple Table[3310:20b] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)' My URL returns the following string: first,second,third,fourth And here is the iphone code with the book's working example commented out #import "Simple_TableViewController.h" @implementation Simple_TableViewController @synthesize listData; - (void)viewDidLoad { /* //working code from book NSArray *array = [[NSArray alloc] initWithObjects:@"Sleepy", @"Sneezy", @"Bashful", @"Bashful", @"Happy", @"Doc", @"Grumpy", @"Thorin", @"Dorin", @"Norin", @"Ori", @"Balin", @"Dwalin", @"Fili", @"Kili", @"Oin", @"Gloin", @"Bifur", @"Bofur", @"Bombur", nil]; self.listData = array; [array release]; */ //code from interwebz that crashes NSString *urlstr = [[NSString alloc] initWithFormat:@"http://www.mysite.com/folder/iphone-test.php"]; NSURL *url = [[NSURL alloc] initWithString:urlstr]; NSString *ans = [NSString stringWithContentsOfURL:url]; NSArray *listItems = [ans componentsSeparatedByString:@","]; self.listData = listItems; [urlstr release]; [url release]; [ans release]; [listItems release]; [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.

  • Android question. Is there a link to a simple example of changing the screen brightness for an activ

    - by John
    There are apparently at least three different techniques for changing screen brightness in the Android OS. Two of them no longer work post-cupcake and the third accepted technique evidently has a bug. I would like to increase screen brightness at the start of a one-view activity then turn the brightness back to the user setting at the end of the activity. No buttons, no second view or second activity. Just a maxed brightness at start and a return to original brightness setting at the end of the activity. The examples of the current technique using WindowManager.LayoutParams that I have located range from 2 lines of code WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.screenBrightness = 100 / 100.0f; getWindow().setAttributes(lp); to several pages of source code and numerous activities. Is there a simple example of maxing the screen brightness at start that someone can provide a link to? Thank you for reading my question.

Sometimes the packets that are received are not echoed back. For this I have introduced a delay after receiving and the no. of failures reduced but the problem still exists. Can someone suggest something? Later on I would like to run two server applications simultaneously on two different ports. Regards, Satinder Singh

  • Ruby: Is there a better way to iterate over multiple (big) files?

    - by zxcvbnm
    Here's what I'm doing (sorry for the variable names, I'm not using those in my code): File.open("out_file_1.txt", "w") do |out_1| File.open("out_file_2.txt", "w") do |out_2| File.open_and_process("in_file_1.txt", "r") do |in_1| File.open_and_process("in_file_2.txt", "r") do |in_2| while line_1 = in_1.gets do line_2 = in_2.gets #input files have the same number of lines #process data and output to files end end end end end The open_and_process method is just to open the file and close it once it's done. It's taken from the pickaxe book. Anyway, the main problem is that the code is nested too deeply. I can't load all the files' contents into memory, so I have to iterate line by line. Is there a better way to do this? Or at least prettify it?

  • Android draw using SurfaceView and Thread

    - by Morten Høgseth
    I am trying to draw a ball to my screen using 3 classes. I have read a little about this and I found a code snippet that works using the 3 classes on one page, Playing with graphics in Android I altered the code so that I have a ball that is moving and shifts direction when hitting the wall like the picture below (this is using the code in the link). Now I like to separate the classes into 3 different pages for not making everything so crowded, everything is set up the same way. Here are the 3 classes I have. BallActivity.java Ball.java BallThread.java package com.brick.breaker; import android.app.Activity; import android.os.Bundle; import android.view.Window; import android.view.WindowManager; public class BallActivity extends Activity { private Ball ball; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); ball = new Ball(this); setContentView(ball); } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); setContentView(null); ball = null; finish(); } } package com.brick.breaker; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android.view.SurfaceHolder; import android.view.SurfaceView; public class Ball extends SurfaceView implements SurfaceHolder.Callback { private BallThread ballThread = null; private Bitmap bitmap; private float x, y; private float vx, vy; public Ball(Context context) { super(context); // TODO Auto-generated constructor stub bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ball); x = 50.0f; y = 50.0f; vx = 10.0f; vy = 10.0f; getHolder().addCallback(this); ballThread = new BallThread(getHolder(), this); } protected void onDraw(Canvas canvas) { update(canvas); canvas.drawBitmap(bitmap, x, y, null); } public void update(Canvas canvas) { checkCollisions(canvas); x += vx; y += vy; } public void checkCollisions(Canvas canvas) { if(x - vx < 0) { vx = Math.abs(vx); } else if(x + vx > canvas.getWidth() - getBitmapWidth()) { vx = -Math.abs(vx); } if(y - vy < 0) { vy = Math.abs(vy); } else if(y + vy > canvas.getHeight() - getBitmapHeight()) { vy = -Math.abs(vy); } } public int getBitmapWidth() { if(bitmap != null) { return bitmap.getWidth(); } else { return 0; } } public int getBitmapHeight() { if(bitmap != null) { return bitmap.getHeight(); } else { return 0; } } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { // TODO Auto-generated method stub } public void surfaceCreated(SurfaceHolder holder) { // TODO Auto-generated method stub ballThread.setRunnable(true); ballThread.start(); } public void surfaceDestroyed(SurfaceHolder holder) { // TODO Auto-generated method stub boolean retry = true; ballThread.setRunnable(false); while(retry) { try { ballThread.join(); retry = false; } catch(InterruptedException ie) { //Try again and again and again } break; } ballThread = null; } } package com.brick.breaker; import android.graphics.Canvas; import android.view.SurfaceHolder; public class BallThread extends Thread { private SurfaceHolder sh; private Ball ball; private Canvas canvas; private boolean run = false; public BallThread(SurfaceHolder _holder,Ball _ball) { sh = _holder; ball = _ball; } public void setRunnable(boolean _run) { run = _run; } public void run() { while(run) { canvas = null; try { canvas = sh.lockCanvas(null); synchronized(sh) { ball.onDraw(canvas); } } finally { if(canvas != null) { sh.unlockCanvasAndPost(canvas); } } } } public Canvas getCanvas() { if(canvas != null) { return canvas; } else { return null; } } } Here is a picture that shows the outcome of these classes. I've tried to figure this out but since I am pretty new to Android development I thought I could ask for help. Does any one know what is causing the ball to be draw like that? The code is pretty much the same as the one in the link and I have tried to experiment to find a solution but no luck. Thx in advance for any help=)

  • How convince other developers not to ignore Exceptions?

    - by Mnementh
    Recently I encountered a bug in an application I took over from another developer. I debugged for the reason and over an hour later I realized, that the problem wasn't the code producing the exception, but some code executed before this returning wrong data. If I dived into this, I encountered the following: try { ... } catch (XYException e){} If the Exception would have been propagated (a change I did), I would have found the reason for the bugs in a few minutes, as the stacktrace had pointed me to the problem. So how can I convince other developers to never catch and ignore exceptions in this way?

    I have been having great trouble getting my sprite to jump. So far I have a section of code which with a single tap of "W" will send the sprite in a constant velocity upwards. I need to be able to make my sprite come back down to the ground a certain time or height after begining the jump. There is also a constant pull of velocity 2 on the sprite to simulate some kind of gravity. // Walking = true when there is collision detected between the sprite and ground if (Walking == true) if (keystate.IsKeyDown(Keys.W)) { Jumping = true; } if (Jumping == true) { spritePosition.Y -= 10; } Any ideas and help would be appreciated but I'd prefer a modified version of my code posted if at all possible.

  • How do I add a combo box to a DataGrid?

    - by FigBug
    I want to add a ComboBox to a DataGrid. So far, the only way I've found to do it is like this: <mx:DataGridColumn headerText="Header" dataField="src" > <mx:itemRenderer> <mx:Component> <mx:ComboBox dataProvider="{data.srcChoices}" /> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> The problem is the initial value of the ComboBox isn't set correctly. If I hard code the choices, then the initial value is set correctly. I can't hard code the choices. Any idea what I should do?

  • ApplicationCommand.Paste happens twice

    - by Carlo
    Hi, well this is driving me crazy. We have a command like so: <CommandBinding Command="ApplicationCommands.Paste" CanExecute="HasClipboardData" Executed="OnPasteExecuted"/> And the code for OnPasteExecuted is this: private void OnPasteExecuted(object sender, ExecutedRoutedEventArgs e) { CurrentView.Paste(); e.Handled = true; } That code gets executed twice, and I have no idea why, we also have the other commands: Cut, Copy, Undo, Redo, those work just fine, the problem is only with Paste. Let me know if you have any idea of what could be going on. Thanks!

  • CSS : overflow : auto will not work under FireFox 3.6.2

    - by Michael Mao
    Hello everyone: This is a CSS related question, I got one good answer from my previous question, which suggested to use some CSS code like overflow:auto together with a fixed height container. And here is my actual implementation : on uni server Please follow the instructions on screen and buy more than 4 kinds of tickets. If you are using IE8, Opera, Safari, Chrome, you would notice that the lower right corner of the page now has a vertical scroll bar, which scrolls the content inside it and prevent it from overflowing. That's what I want to have in this section. Now the problem is, this would not do in FireFox 3.6.2. Am I doing something not compliant to the CSS standard or FireFox has its own way of overflow control? You can inspect the elements on screen, and all controlling functions are done in one javascript using jQuery. All CSS code are kept in a separated file as well. According to the professor, FireFox would be the target browser, although the version was set to 2.0...
