I downloaded new Xcode 11 today and when I am trying to open my project, Xcode will always crash. Does anyone else experience this problem ? I have provided part of crash log. It's IDE related problem, but I would be really glad, someone has a solution to this.

I have deleted caches in library, derivated data, even disabled automatic signing, but none of these work.

UPDATE

Project can be opened, when I logout from developer account, otherwise, this crash always occurs.

My Xamarin application works perfectly on debug mode but crashes on release mod. I get this error: "Unfortunately App has stopped". I connected my phone through USB and when I run the app in release mode I get this error.

Unfortunately I can't debug the app in release mod because I get this message in the Output window: "Android application is running (debug is disabled in android project properties)", although the "Enable developer instrumentation" box is checked. I tried all linking alternative None/SDK/SDK and User but still doesn't work.

Is there a way to see what causes the crash, in a log file or something else ?

This crash is happening only on iOS 13.3.1 & 13.4.0

This crash is happening randomly and is a real deterrent to my customers.

I have update fabric library to lastest version (1.10.2).

I'm working on VB6 project where I need to have keyboard short-cuts for Buttons on Toolbar Control. To accomplish this, I have used Win32 Hooks library from vbAccelerator. Here's my IWindowsHook_HookProc function, that I use to retrieve Key strokes & perform action based on pressed short-cut (Ctrl + N for New, Ctrl + O for Open and Ctrl + S for Save) , but the I don't know what's wrong with the code that crashes my application along with VB6 IDE. The function is currently incomplete as I just tried to identify Ctrl + N key combination to test this feature. Please help me out.... :-|

Private Function IWindowsHook_HookProc(ByVal eType As EHTHookTypeConstants, ByVal nCode As Long, ByVal wParam As Long, ByVal lParam As Long, bConsume As Boolean) As Long
If KeyboardlParam(lParam).KeyDown Then
     Select Case True
           Case Me.ActiveControl = Me
                 If wParam = vbKeyControl + vbKeyN Then
                        frmNewReport.show
                        bConsume = True
                 End If
     End Select
End If

I've been using Android Studio for 3 months now and one of the apps I started on it has become fairly large. The memory usage indicated at the bottom right of the program says my allocated heap is maxed at 494M.

When I start to change the XML files my memory usage quickly reaches that cap and the IDE crashes with an Out Of Memory error like this.

I've tried to increase the heap size using this but so far there has been no effect.

I've looked at dozens of articles and other questions on how to increase the heap size but none of their answers are working. No matter what I do to the VMOPTIONS or the IDE settings the heap size never increases. I believe I am editting the correct file for the VMOPTIONS because if I purposely give it an invalid command Android Studio complains about it and doesn't start.

I'm using windows 7 - 64 bit and have 16GB RAM. Has anyone else had this problem with Android Studio? And were you able to fix it?

I have this old Objective-C project built for iOS 9 that I have to update.

I am testing the project and after doing a lot of updates, it is now crashing.

The crash shows no symbol and it is like this shown on Xcode console:

I have tried to symbolicate that manually but this is not a regular crash file and is not recognized by ´symbolicatecrash` as one.

I have checked build settings and I have

1. debug information format : Dwarf with dSym file turned on for debug.
2. I have strip symbols disabled.

Note: the device has no crash logs. This is iOS.

Any ideas?

I've installed Laravel (Framework version 6.18.1) on my local setup using the Laravel installer. I use Docker with Devilbox and Xdebug enabled. The problem I run into is that everytime a page renders a PHP error, I get a 503 error in my browser (instead of an Xdebug error or Laravel error page). When I run artisan functions that cause a php error, I get memory errors in the console. As soon as I disable Xdebug, I get the usual Laravel errors. I'd like to use Laravel with Xdebug enabled, but I can't figure out why the two won't play nice together. I have searched for solutions but it seems I'm the only one. The strange this is that I've also tried it in another computer with a similar setup (Docker+Devilbox) and I run into the same problem.

Does anybody know why Xdebug and Laravel won't co-exist on my system and how I can fix it?

I'm trying to figure out what the problem with my StreamBuilder/Stream is:

Stream<Page> pageStream;

@override
void initState() {
  super.initState();
  final firestoreService = Provider.of<FirestoreService>(context, listen: false);
  final book = Provider.of<Book>(context, listen: false);
  final pageNumber = Provider.of<int>(context, listen: false);
  pageStream = firestoreService.getStreamOfPage(bookId: book.bookId, pageNumber: pageNumber);
}

@override
Widget build(BuildContext context) {
  return StreamBuilder(
          stream: pageStream,
          builder: (context, snapshot) {
            if (snapshot.connectionState == ConnectionState.waiting ||
                snapshot.connectionState == ConnectionState.none) {
              return CupertinoActivityIndicator();
            }

            if (snapshot.hasError) {
              return Text('the error is = ${snapshot.error.toString()}');
            }

            Page page = snapshot.data;

            return Container(
              color: Colors.purple,
              height: 30,
              width: 30,
            );
          }

  );
}

So in the initstate method I get the stream which is stored in the state and then assigned to the StreamBuilder.

The method that gets the Stream is:

Stream<Page> getStreamOfPage(
    {@required String bookId, @required int pageNumber}) {
  try {
    Stream<Page> pageStream = _fireStore
        .document('books/$bookId/$pageNumber')
        .snapshots()
        .map((docSnapshot) => Page.fromMap(map: docSnapshot.data));
    return pageStream;
  } catch (e) {
    print(
        'Could not get stream of page with bookId = $bookId and pageNumber = $pageNumber');
    print(e);
    return null;
  }
}

The print statements I wrote inside the constructor Page.fromMap() (including one at the end of the constructor) were executed so I assume the error is not there. Print statements I added inside the map method (from .snapshots().map(...)) were not executed, which makes no sense to me because the ones in the Page constructor are executed (with the right values from the firebase document).

i just keep getting an error "app has stopped" while running the app in android studio, the logcat does point out the problem but i am a starter at this and have no clue how to get it done. Plz advise. Thanks! enter image description here

I am trying to write a program that can convert HTTP URLs to torrents. This project is working basically working for download links contain small files. Like a file of 1-500Mb. My problem is if the file size is more than that the app is crashing or getting a timeout. So I want to know how to fix this. Below is my code and link to Github.

I am developing an application, and everytime I run it, I get the message:

Unfortunately, MyApp has stopped.

What can I do to solve this?

About this question - obviously inspired by What is a stack trace, and how can I use it to debug my application errors?, there are lots of questions stating that their application has crashed, without any further detail. This question aims to instruct novice Android programmers on how to try and fix their problems themselves, or ask the right questions.

I have an app which has UITabbarController as the initial window(after logging-in i set it as rootViewController)

This tabbarController has 4 different tabs in it which are all UIViewControllers embedded in a UINavigationController.

In my tabbarController when i am making the initial configurations i set tabs like below:

• First I create the viewControllers:

  let tableViewController1 = tableViewController1(nibName: "tableViewController1", bundle: nil)
  let tableViewController2 = tableViewController2(nibName: "tableViewController2", bundle: nil)
  let tableViewController3 = tableViewController3(nibName: "tableViewController3", bundle: nil)
  let profileViewController = ProfileViewController(nibName: "ProfileViewController", bundle: nil)
  

• Then I embed them inside navigationControllers:

  let navController1 = UINavigationController(rootViewController: tableViewController1)
  let navController2 = UINavigationController(rootViewController: tableViewController2)
  let navController3 = UINavigationController(rootViewController: tableViewController3)
  let navController4 = UINavigationController(rootViewController: profileViewController)
  

• Finally, add the navigationControllers as tabbarController's viewControllers

  viewControllers = [navController1,navController2,navController3,navController4]

I looked it up online and this way of using it seems correct. Ex: https://medium.com/@ITZDERR/uinavigationcontroller-and-uitabbarcontroller-programmatically-swift-3-d85a885a5fd0. However i'm receiving crash logs from my live app as below

Crash, child view controller:<UINavigationController: 0x160b3400>
should have parent view controller:<ProfileViewController: 0x16098800>
but actual parent is:<MyApp.MainTabBarController: 0x16064c00>

The problem in here is that the crash says profileViewController should be the parent of the navigationController however i embedded profileViewController inside the navigationController and added as tabbarController's viewControllers, so in my opinion the order is correct.

I searched for this crash and it seems like i'm skipping a step of either using addChildViewController or removing a parent somewhere, but couldn't figured out.

I have find related link to this but non-of them helped me to solve this issue.

Example links:

• http://www.iriphon.com/2012/03/31/uncaught-exception-uiviewcontrollerhierarchyinconsistency-reason-child-view-controller-should-have-parent-view-controller-but-actual-parent-is-or-apples-new-uiviewcontroller-hierarc/

It is crashing in this method func carbonTabSwipeNavigation(_ carbonTabSwipeNavigation: CarbonTabSwipeNavigation, viewControllerAt index: UInt) -> UIViewController { let sb = UIStoryboard.init(name: storybordname, bundle: nil) var viewcontroller:UIViewController! viewcontroller = sb.instantiateViewController(withIdentifier: controllername) return viewcontroller } When i Checked after putting breakpoint its crashing on the first line super.viewDidLoad()

I developed a media app using ionic 4 And it have video uploading option in my app, after choosing that video from library i want to check the video it works fine 20 days after i upload to the playstore

this.streamingMedia.playVideo('https://path/to/video/stream', options);

crash the app.

import UIKit
import AVFoundation


class ViewController: UIViewController {

    var audioPlayer: AVAudioPlayer!


    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func playButtonPressed(_ sender: UIButton) {
    }


             // Set the sound file name & extension
        let alertSound = URL(fileURLWithPath: Bundle.main.path(forResource: "lets communicate", ofType: "mp3")!)

So this is my code. I keep getting an error and my program crashes. I am trying to make a simple app for my grandson who was diagnosed with autism. So it's just a simple button and sound app. I am having a hard time with the sound button part...

I had around 2600 tabs on OneTab, and they were available till yesterday, but suddenly Chrome browser was not responding so I forcibly closed it and re-opened it, after saving my new tabs I found that OneTab was empty, and there're only those new tabs, the previous 2600 tabs were gone!

Is there any way I can get these tabs back? I thought maybe there's a temporary backup folder in any place inside the computer, knowing that the computer didn't crash but it's only chrome , and that NOW OneTab already saved 112 new tabs.

I found this answer about finding 2 files and copying them, Restore OneTab list of tabs after computer crash but it didn't help because:

1. I found only one of these files.
2. My case is different as I'm not restoring OneTab from Computer to another, it's on the same computer, so I don't have a backup.

How to find the old files?

Loading different size of images into ImageView using Glide Library. But not sure why glide fails to handle the memory consumption, recycle and reuse it.

Gradle:

api 'com.github.bumptech.glide:glide:4.3.0'

Usage:

@BindingAdapter({"imageUrl"})
public static void imageUrl(ImageView view, String imageUrl) {
    try {
        if (imageUrl!=null) {
            Glide.with(view.getContext()).load(imageUrl).into(view);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Recently I have lots of problems with eclipse, it keeps on crashing, closing abruptly, don't work well at all.

It happens too much, like in every 10 -15 minutes.

The CPU and RAM are 50% free when this happens.

This is the eclipse.ini file:

    -startup
    plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize

    --launcher.defaultAction
    openFile
    -vmargs
    -Xms40m
    -Xmx512m

What is the problem ? It's really bothering!
