  • Showing a Toast using "setUncaughtExceptionHandler"

    - by VitalyB
    Hi everyone, I'm trying to do a simple global exception handler in my Android app and I am having troubles: public class TicTacToe extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Thread.currentThread().setUncaughtExceptionHandler(new UncaughtExceptionHandler() { @Override public void uncaughtException(Thread thread, Throwable ex) { Toast.makeText(this, "TOAST", Toast.LENGTH_LONG); } }); setContentView(R.layout.main); } } I'm a rather new with both Android AND java but in .NET that would work. Can't I access local variable from anonymous methods in java? If so, how should I rewrite it? Thanks, Vitaly

  • Is it possible to change where things are in Chrome's Developer Tools Script panel?

    - by T.J. Crowder
    When debugging browser-based apps using Google Chrome's Developer Tools, is there a way to change the locations of the various panes? Specifically in the Scripts panel (though I suppose it's a general question). E.g., the Watch Expressions, the Call Stack, the code pane, etc.? The defaults are okay (console at bottom, code pane upper left, a column of Watch Expressions, Call Stack, Scope Vars, etc. in the upper right), but I'd rather swap things around a bit if it's possible. There doesn't seem to be anything to grab (other than for sizing) and I haven't found a way in my searching so far, but there are (still) some things about Chrome's options that aren't ... well-advertised in the UI, shall we say :-), especially around developer tools.

  • Need help understanding _set_security_error_handler()

    - by Emil D
    So , I've been reading this article: http://msdn.microsoft.com/en-us/library/aa290051%28VS.71%29.aspx And I would like to define my custom handler.However, I'm not sure I understand the mechanics well.What happens after a call is made to the user-defined function ( e.g. the argument of _set_security_error_handler() ) ? Does the program still terminate afterward ? If that is the case, is it possible to terminate only the current thread(assuming that it is not the main thread of the application).AFAIK, each thread has its own stack , so if the stack of a thread gets corrupted, the rest of the application shouldn't be affected. Finally, if it is indeed possible to only terminate the current thread of execution, what potential problems could such an action cause? I'm trying to do all this inside an unmanaged C++ dll that I would like to use in my C# code.

  • Android ignoring my setWidth() and setHeight()

    - by popoffka
    So, why does this code: package org.popoffka.apicross; import android.app.Activity; import android.os.Bundle; import android.widget.Button; public class Game extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Button testButton = new Button(this); testButton.setBackgroundResource(R.drawable.cell); testButton.setWidth(20); testButton.setHeight(20); setContentView(testButton); } } ...produce this thing: http://i42.tinypic.com/2hgdzme.png even though there's a setWidth(20) and setHeight(20) in the code? (R.drawable.cell is actually a 20x20 PNG image containing a white cell with a silver border)

  • is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified

    - by user355859
    is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified manifest.xml?? I know there are tools such as baksmali / smali to disassemble / re-assemble given classes.dex from .apk, but not sure limitation what could be modified from there on? I'm trying to add additional activity, to modify starting launcher activity (may be from androidmanifest.xml) from original apk, then re-pack and sign to make complete single .apk... all need to be done out of build time, no raw source or build structure visible, only .apk as input... ANY IDEA?

  • C# StringBuilder related question

    - by Sef
    Hello, I have written a program for a stack. For this i needed a StringBuilder to be able to show me what was in the stack else i would get the class name instead of the actual values inside. My question is there any other way except for a StringBuilder for such kind of problem? Also in what other kind of cases does this kind of problem happen? Also the way i have written the StringBuilder felt very awkward when i needed several things on 1 line. public override string ToString() { StringBuilder builder = new StringBuilder(); foreach (int value in tabel) { builder.Append(value); builder.Append(" "); } if (tabel.Length == tabel.Length) // this is a bit messy, since I couldn't append after the rest above { builder.Append("(top:"); builder.Append(top); builder.Append(")"); } return builder.ToString(); }/*ToString*/ Regards.

  • How to break on unhandled exceptions in Silverlight

    - by Bruno Martinez
    In console .Net applications, the debugger breaks at the point of the throw (before stack unwinding) for exceptions with no matching catch block. It seems that Silverlight runs all user code inside a try catch, so the debugger never breaks. Instead, Application.UnhandledException is raised, but after catching the exception and unwinding the stack. To break when unhandled exceptions are thrown and not catched, I have to enable first chance exception breaks, which also stops the program for handled exceptions. Is there a way to remove the Silverlight try block, so that exceptions get directly to the debugger?

  • most popular j2ee based websites

    - by krishna
    J2EE as I understand is used to build Enterprise applications. My question is :What are the most popular public facing(internet) sites using j2ee stack. The one's that I know of are : linkedIn.com ,evite.com and sun ibm and oracle (obviously) Eclipse.org uses php, I wonder why? If you have worked on/know any other sites, can your share your experience and also the technologies used(if that's not an issue)? EDIT:It doesn't have to use the full stack. EDIT : There are quite a few ecommerce websites like bestbuy.com. I know this bcos I worked with the ATG(atg.com) ecommerce suite and their website lists their clients. Iam looking for those kind of examples and also your experience working on them. Please limit to only internet sites

  • memory alignment issues with union

    - by confucius
    Hi all, Is there guarantee, that memory for this object will be properly aligned if we create this object of this type in stack? union my_union { int value; char bytes[4]; }; If we create char bytes[4] in stack and then try to cast it to integer there might be alignment problem. We can avoid that problem by creating it in heap, however, is there such guarantee for union objects? Logically there should be, but I would like to confirm. Thanks.

  • Dynamics AX 2009 - Modify insert into smmActivities from ProjTableWizard?

    - by core
    I am an AX newbie, and I need to make a modification to the ProjTableWizard form code and have not been able to locate where I need to make the change. Essentially what I need to do is modify the part of the Wizard process when creating a sub-project. I need to figure out how a line is inserted into the smmActivities table, so that I can modify the “Activity Purpose” field (prefix it with the Activity Purpose of its parent Project from the ProjTable Form) following the “Finish” button click on the ProjTableWizard form. So far I have been unable to figure out how the ProjTableWizard form is triggering this insert into smmActivities (and how the Purpose field is being populated from the Wizard). Any help would be greatly appreciated! Thanks

  • Are there plans to make a non-programming general version of StackOverFlow like Yahoo Answer! [close

    - by RoboShop
    Firstly, I would like to say I think StackOverflow is a really great website, not just from a content perspective, but from a design perspective. The UI is designed in a way that makes it easy to use and the points are great incentives to be a productive part of the community. I was wondering, is there a part of the site, or maybe is there plans to make a new site, which is not programming driven. Like a general knowledge site but with StackOverflow as the engine. I use sites like Yahoo Answer! and they can be useful. But I think the main difference between Stack Overflow and Yahoo Answer is that Yahoo Answer encourages content indiscriminately, whereas Stack Overflow is disciplined enough that it only encourages content that are helpful or useful. I find it great that I can load up a question and the best answer pops up immediately, and the bad answers are voted down. Thanks

  • Core dump utility for .NET

    - by Dave
    In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

  • Does MATLAB perform tail call optimization?

    - by Shea Levy
    I've recently learned Haskell, and am trying to carry the pure functional style over to my other code when possible. An important aspect of this is treating all variables as immutable, i.e. constants. In order to do so, many computations that would be implemented using loops in an imperative style have to be performed using recursion, which typically incurs a memory penalty due to the allocation a new stack frame for each function call. In the special case of a tail call (where the return value of a called function is immediately returned to the callee's caller), however, this penalty can be bypassed by a process called tail call optimization (in one method, this can be done by essentially replacing a call with a jmp after setting up the stack properly). Does MATLAB perform TCO by default, or is there a way to tell it to?

  • How can I set a ringtone for an individual contact on Android ?

    - by PHP_Jedi
    How can I set a ringtone for an individual contact on Android ? I have found a way to set the default ringtone that applies to all contacts without an individual ringtone. But that is not what i'm trying to accomplish. I want the application to have a button "Apply ringtone to contact". When i click, I start an activityForResult displaying a list of all contacts on the phone. When a contact is selected, the contact activity closes and returns with a uri to the contact. Now all the app needs to do is to apply the selected ringtone to that spesific contact. The code for displaying and selecting contacts by an activity is already implemented and seems to work on with the app. Its only the last part left, and I have no clue about how to solve this. Any help would be usefull.

  • pushScene and popScene or replaceScene . which should we use and when ?

    - by srikanth rongali
    I am using push scene to get the next scene. But, I read that for each PushScene the scene is stored in stack. The memory usage is more. So, I am using the replaceScene in place of pushScene. But, with replace scene I am getting the memory-bad-access message in debugger. So, I want to popScene after using it, so that the retain count is zero. But, I am confused in using popScene. If I have a Scene1 and Scene2. I used the following to go in to Scene2. Now I need to remove Scene1 from stack. [[CCDirector sharedDirector] pushScene:Scene2]; Where should I write the popScene to popScene1. How to get the previous scene in current running scene ? Thank you/

  • Can't resolve CalledFromWrongThreadException with Handler

    - by michel
    I will try to keep it simple: In my main activity I make a handler: public class ARViewer extends ARDisplayActivity { public final MHandler mHandler = new MHandler(this); public void onCreate(Bundle savedInstanceState) { ...

    I'm reorganzing a legacy mixed (managed and unmanaged DLLs) application so that the main application segment is unmanaged MFC and that will call a C++ DLL compiled with /clr flag that will bridge the communication between the managed (C# DLLs) and unmanaged code. Unfortuantely, my changed have resulted in an Access violation that occurs before the application InitInstance() is called. This makes it very difficult to debug. The only information I get is the following stack trace. > 64006108() ntdll.dll!_ZwCreateMutant@16() + 0xc bytes kernel32.dll!_CreateMutexW@12() + 0x7a bytes So, here are some sceanrios I've tried. - Turned on Exceptions-Win32 Exceptions-c0000005 Access Violation to break when Thrown. Still the most detail I get is from the above stack trace. I've tried the application with F10, but it fails before any breakpoints are hit and fails with the above stack trace. - I've stubbed out the bridge DLL so that it only has one method that returns a bool and that method is coded to just return false (no C# code called). bool DllPassthrough::IsFailed() { return false; } If the stubbed out DLL is compiled with the /clr flag, the application fails. If it is compiled without the /clr flag, the application runs. - I've created a stub MFC application using the Visual Studio wizard for multidocument applications and call DllPassthrough::IsFailed(). This succeeds even with the /clr flag used to compile the DLL. - I've tried doing a manual LoadLibrary on winmm.lib as outlined in the following note Access violation when using c++/cli. The application still fails. So, my questions are how to solve the problem? Any hints, strategies, or previous incidents. And, failing that, how can I get more information on what code segment or library is causing the access exception? If I try more involved workarounds like doing LoadLibrary calls, I'd like to narrow it to the failing libraries. Thanks. BTW, we are using Visual Studio 2008 and the project is being built against the .NET 2.0 framework for the managed sections.

  • Android: roatating images in a loop.

    - by user573736
    Hello, I am trying with no success to modify the code example from: http://www.inter-fuser.com/2009/08/android-animations-3d-flip.html so it will rotate the images in a loop, when clicking on the image once. (second click should pause). I tried using Handler and threading but cannot update the view since only the main thread can update UI. Exception I get from the code below: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. [in 'image1.startAnimation(rotation);' ('applyRotation(0, 90);' from the main thread)] package com.example.flip3d; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.animation.AccelerateInterpolator; import android.widget.ImageView; public class Flip3d extends Activity { private ImageView image1; private ImageView image2; private boolean isFirstImage = true; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); image1 = (ImageView) findViewById(R.id.image01); image2 = (ImageView) findViewById(R.id.image02); image2.setVisibility(View.GONE); image1.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { if (isFirstImage) { applyRotation(0, 90); isFirstImage = !isFirstImage; } else { applyRotation(0, -90); isFirstImage = !isFirstImage; } } }); } private void applyRotation(float start, float end) { // Find the center of image final float centerX = image1.getWidth() / 2.0f; final float centerY = image1.getHeight() / 2.0f; // Create a new 3D rotation with the supplied parameter // The animation listener is used to trigger the next animation final Flip3dAnimation rotation = new Flip3dAnimation(start, end, centerX, centerY); rotation.setDuration(500); rotation.setFillAfter(true); rotation.setInterpolator(new AccelerateInterpolator()); rotation.setAnimationListener(new DisplayNextView(isFirstImage, image1, image2)); if (isFirstImage) { image1.startAnimation(rotation); } else { image2.startAnimation(rotation); } } } How can I manage to update the UI and control the rotation within onClick listener? Thank you, Oakist

  • Show only one validation error-message using replaceWith

    - by timkl
    I am currently working with the jQuery validation plugin, and I want to show only one error-message before the form itself. Right now the validation shows all the error-messages on top of each others as they stack up, as you can see in my live example: http://timkjaerlange.com/foobar/stack-stuff/validate-test.html This is my jQuery: $(document).ready(function() { $("form").validate({ rules: { // bunch of rules here, left out to keep it simple }, messages: { // messages goes here }, errorElement: 'div', errorClass: 'error', errorPlacement: function(error, element) { error.insertBefore('form'); // this is what I've got $('div').replaceWith(error); // trying to replace the prev error } }); }); Anybody know how to this? Is this the best way to show only one error-message? Any help is highly appreciated.

    I seem to be having trouble with the linkify I am using in my Custom Adapter. For some reason I recieve the following stack track when I click on one of the links: 06-07 20:49:34.696: ERROR/AndroidRuntime(813): Uncaught handler: thread main exiting due to uncaught exception 06-07 20:49:34.745: ERROR/AndroidRuntime(813): android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag.

Does anyone have any ideas? Thanks in advance for your help!

  • Performance of SHA-1 Checksum from Android 2.2 to 2.3 and Higher

    - by sbrichards
    In testing the performance of: package com.srichards.sha; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; import java.io.IOException; import java.io.InputStream; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; import java.util.zip.ZipEntry; import java.util.zip.ZipFile; import com.srichards.sha.R; public class SHAHashActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView tv = new TextView(this); String shaVal = this.getString(R.string.sha); long systimeBefore = System.currentTimeMillis(); String result = shaCheck(shaVal); long systimeResult = System.currentTimeMillis() - systimeBefore; tv.setText("\nRunTime: " + systimeResult + "\nHas been modified? | Hash Value: " + result); setContentView(tv); } public String shaCheck(String shaVal){ try{ String resultant = "null"; MessageDigest digest = MessageDigest.getInstance("SHA1"); ZipFile zf = null; try { zf = new ZipFile("/data/app/com.blah.android-1.apk"); // /data/app/com.blah.android-2.apk } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } ZipEntry ze = zf.getEntry("classes.dex"); InputStream file = zf.getInputStream(ze); byte[] dataBytes = new byte[32768]; //65536 32768 int nread = 0; while ((nread = file.read(dataBytes)) != -1) { digest.update(dataBytes, 0, nread); } byte [] rbytes = digest.digest(); StringBuffer sb = new StringBuffer(""); for (int i = 0; i< rbytes.length; i++) { sb.append(Integer.toString((rbytes[i] & 0xff) + 0x100, 16).substring(1)); } if (shaVal.equals(sb.toString())) { resultant = ("\nFalse : " + "\nFound:\n" + sb.toString() + "|" + "\nHave:\n" + shaVal); } else { resultant = ("\nTrue : " + "\nFound:\n" + sb.toString() + "|" + "\nHave:\n" + shaVal); } return resultant; } catch (IOException e) { e.printStackTrace(); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } return null; } } On a 2.2 Device I get average runtime of ~350ms, while on newer devices I get runtimes of 26-50ms which is substantially lower. I'm keeping in mind these devices are newer and have better hardware but am also wondering if the platform and the implementation affect performance much and if there is anything that could reduce runtimes on 2.2 devices. Note, the classes.dex of the .apk being accessed is roughly 4MB. Thanks!
