I've set a small icon to my notificaton builder using

NotificationCompat.Builder builder = new NotificationCompat.Builder(mContext)
.setSmallIcon(R.drawable.location_off_24dp);

location_off_24dp is actually a SVG file in my project.

Issue is that I get crash with this code on pre-lollipop devices.

Crash report:

  android.app.RemoteServiceException: Bad notification posted from package com.com.example.app: Couldn't create icon: StatusBarIcon(pkg=com.example.app.clientuser=0 id=0x7f02010e level=0 visible=true num=0 )

I know we can use app:srcCompat="@drawable/vector_file" in the layouts. But when we pass the SVG drawable resource ID to PendingIntent, will the system use something of srcCompat kind of version so it could apply to pre-lollipop too or it expects drawable to be a direct image ?

How do I use SVG as small Icon in Notification for pre-lollipop devices?

I want to click an image and send it to the server. the code works well if we are using gallery function but fails to work when it is swap by camera function.

I am able to open the camera, click the image and after this select if correct or wrong.

after this step the app crash. Next to this step, image needs to be sent to the cropping screen.

here is the code:

Future getImage() async {
    // var image = await ImagePicker.pickImage(source: ImageSource.gallery);
      var _image = await ImagePicker.pickImage(source: ImageSource.camera);
      croppedFile = await ImageCropper.cropImage(
      sourcePath: _image.path,
      aspectRatioPresets: [
        CropAspectRatioPreset.square,
        CropAspectRatioPreset.ratio3x2,
        CropAspectRatioPreset.original,
        CropAspectRatioPreset.ratio4x3,
        CropAspectRatioPreset.ratio16x9
      ],
      androidUiSettings: AndroidUiSettings(
          toolbarTitle: 'Cropper',
          toolbarColor: Colors.deepOrange,
          toolbarWidgetColor: Colors.white,
          initAspectRatio: CropAspectRatioPreset.square,
          lockAspectRatio: false),
      iosUiSettings: IOSUiSettings(
        minimumAspectRatio: 1.0,
      )
    );
    if (_pickInProgress) {
        return;
    }
      _pickInProgress = true;
      if (_image != null) {
        setState(() {
          _newAvatar = croppedFile;
        });
      }
      _pickInProgress = false;
  }

in Android Studio I have the bellow log when filter is used with keyword flutter:

Ubuntu crash output

Both on Ubuntu and windows, my computer will come to a grinding hault and throw errors. It happens randomly. Ram is good and hard drive checks don't show immediate problems. Happens plugged in and unplugged (laptop)... Any ideas?

During work in Pycharm i have monitors issue. When I launch them, laptop crush and monitors turning off. Do you know what's going on? Any ideas?

My app got crashed with Terminated due to signal 13 error while i am running it.

App is getting crashed during this method execution.

@objc func handlePipeNotification(notification: Notification)
{
    inputPipe.fileHandleForReading.readInBackgroundAndNotify()
    if let data = notification.userInfo![NSFileHandleNotificationDataItem] as? Data,
        let str = String(data: data, encoding: String.Encoding.ascii) {
        outputPipe.fileHandleForWriting.write(data)
    }
}

Above method calls every time when something print on debug window.

If I remove this line than there is no issue.

outputPipe.fileHandleForWriting.write(data)

This line is writing back data to debug window.

Help me to solve this error.

I have tried writing a program which idetifies Euler's indicator for numbers lower than a variable DIM. It keeps crashing. I think one of the arrays is the problem. I have tried to tweak my code in numerous ways, but to no avail. Here is my code:

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
    ifstream fin("tramvaie.in");
    ofstream fout("tramvaie.out");
    int t,i,j,n=2,y,DIM=0;
    int x;
    bool ok;
    fin>>t;
    int q[t+1];
    for(i=1; i<=t; i++)
    {
        fin>>x;
        q[i]=x;
        if(x>DIM)
            DIM=x;
    }
    DIM=1000007;
    int F[DIM + 1];
    for(int i =1 ; i <= DIM ; i ++)
        F[i] = i;
    for(int i = 2;  i <= DIM ; i ++)
    {
        if(F[i] == i)
        {
            F[i] --;
            for(int j =2 ; j * i <= DIM ; j ++)
                F[j * i]= F[j * i] / i * (i - 1);
        }
    }
    for(i=1;i<=t;i++)
    {
        fout<<F[q[i]]<<"";
    }
    return 0;
}

I'm trying to create a modular architecture in my project but I came across a very strange error.

I have a project called Application and another called Core.

In "Application" I have a storyboard that has a HomeViewController which imports Core.

In the ViewDidLoad of HomeViewController I have a custom button called btnLater of type RGButton which is declared inside of the Core project.

Xcode's Autocomplete recognizes the public methods when I type "self.btnLater." or "RGButton."

RGButton class on Core proejct:

public class RGButton: UIButton {

// corner radius
public func borderRadius(radius : CGFloat) {
    self.layer.cornerRadius = radius
}
...

HomeViewController ViewDidLoad() on Application project

...
self.btnLater.layer.cornerRadius = 4
self.btnLater.borderRadius(radius: 4.0)
...

So when I run the project... on the line

self.btnLater.layer.cornerRadius = 4

there is no crash... But on the line

self.btnLater.borderRadius(radius: 4.0)

it crashes with the following error:

Thread 1: EXC_BAD_ACCESS (code=257, address=0x1a258656e61)

I fear that some project configuration may be causing this.. but I need some light to help me figure out what the aliens are doing to my project...

Thanks in advance!

A couple of days ago launching both Google Maps and Apple Maps perfectly fine. I updated Flutter to its newest Version while on master channel to 1.13.1. I assume after updating it stopped working. So I changed channels to beta and tried, but still not working. When trying to launch Google Maps or Apple Maps the IOS app crashes and I neither understand the error nor did I find something on the internet.

Any help is much appreciated.

My UI code:

ListTile(
                 title: Text("Launch Google Maps", textAlign: TextAlign.center),
                  onTap: () async {
                    final String clubName =
                        clubs[index].name.toString().replaceAll("", "+");
                    print("Name: $clubName"); // 'Flawless+Club'
                    final String clubCity = clubs[index].stadt;
                    print("Name: $clubCity"); // 'London'
                    final String newGoogleUrl =
                        "https://www.google.com/maps/dir/?api=1&destination=$clubName+$clubCity";

                    if (await canLaunch(newGoogleUrl)) {
                      await launch(newGoogleUrl);
                    } else {
                      throw 'Could not launch $newGoogleUrl';
                    }
                  },
                ),

However, when I try to click on those setting, it always crashed. screenshot

or is there anyway to set those configurations without click those buttons ? Thanks.

I am using android build flavours in react-native application. The app crashes immediately after launch. Below is the build.gradle file 

    flavorDimensions "default"
    productFlavors {
        prod {           
            buildConfigField "String", "BASE_URL", "abc.com"
        }
        dev {
            buildConfigField "String", "BASE_URL", "abc-dev.com"

I try to use a fragment to network call on a Button Click Listener, however, when I click the button to begin network, it will work But When I Double Click Button (Fastly) the program unexpectedly terminates and it shows the error like this:

This piece of code is crashing on iOS 12 with unrecognised selector exception:

[AVPlayerItem externalMetadata]: unrecognized selector sent to instance

However, this code is not crashing on iOS 13.

Apple documentation states that AVPlayerItem has externalMetadata getter and setter since iOS 12.

    let item = AVPlayerItem(url: videoURL)

    let mutableMetadataItem = AVMutableMetadataItem()
    mutableMetadataItem.identifier = AVMetadataIdentifier.commonIdentifierDescription
    mutableMetadataItem.value = 1
    item.externalMetadata.append(mutableMetadataItem)

Could you please help me to understand why is that happening?

In Objective-C, the NSSetUncaughtExceptionHandler can register some functionality to do some last minute logging about the exception.

This doesn't catch something crashing from Swift.

Is it possible to do something like this at a global level in Swift? E.g. do some logging if a crash happens in Swift code, like forced unwrapping a nil optional.

Specifically, I'm doing a utility to log network traffic in the app, and I would like to flush my in-memory data to disk if a crash happens.

I am trying to run search Function in app and it crashes immediately without giving any information

my mvvm code

var userSearch = _apiServices.SearchEmailansPasswordUserAsync(Email , Password,accesstoken);

my Data Services

            var userInformation = await restClient.SearchEmailandPasswordUser(email, pasword, accessToken);
            return userInformation;

        }

my rest Client code

The code below is intended to update a specific link (the B2 ref) for all Excel files in a given folder (the B1 ref). There's an additional condition that it will only save the file down if the number of errors is the same before and afterwards.

However, when I run this it crashes Excel without any indication of why:

    Dim locWS, locWB As String
    Dim wb, ThisWB As Workbook
    Dim oFSO, oFolder, oFiles, oFile As Object
    Dim noErrors, i, j As Integer
    Dim Links As Variant

    'Access the file location with VBA objects
    locWS = Worksheets("Sheet").Range("B1").Value
    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(locWS)
    Set oFiles = oFolder.Files
    i = 0
    Set ThisWB = ThisWorkbook

    'For each file in the path ...
    For Each oFile In oFiles
        'Set the pathname
        locWB = locWS & oFile.Name
        Set wb = Workbooks.Open(locWB)

        'Counts the number of errors in the workbook before updates
        noErrors = ErrorCount(wb)

Any ideas are appreciated. Thanks in advance.

My app got crash with error Terminated due to signal 13.

I am creating input pipe and on that line app got crash with above reason.

 public func openConsolePipe() {

        inputPipe = Pipe()

        outputPipe = Pipe()
        let pipeReadHandle = inputPipe.fileHandleForReading

        dup2(STDOUT_FILENO, outputPipe.fileHandleForWriting.fileDescriptor)
        dup2(STDERR_FILENO, outputPipe.fileHandleForWriting.fileDescriptor)

        dup2(inputPipe.fileHandleForWriting.fileDescriptor, STDOUT_FILENO)
        dup2(inputPipe.fileHandleForWriting.fileDescriptor, STDERR_FILENO)

        NotificationCenter.default.addObserver(self, selector: #selector(self.handlePipeNotification), name: FileHandle.readCompletionNotification, object: pipeReadHandle)

        pipeReadHandle.readInBackgroundAndNotify()
}

I am following This Link for implement this.

Now above tutorial working fine in regular project.

But I am creating framework of this demo and use it another app code.

At that time app got crash on Line.

dup2(inputPipe.fileHandleForWriting.fileDescriptor, STDERR_FILENO)

This is below method in that I am getting all logs from pipe.

@objc func handlePipeNotification(notification: Notification)
{
        inputPipe.fileHandleForReading.readInBackgroundAndNotify()

        if let data = notification.userInfo![NSFileHandleNotificationDataItem] as? Data,
        let str = String(data: data, encoding: String.Encoding.ascii) {

            outputPipe.fileHandleForWriting.write(data)
        }
}

I have a working project with GoogleMaps in it that works fine. I made a copy of that project to make the project modular and now I get an EXC_BAD_ACCESS error when I try to open the map.

here is my pod configuration:

def shared_pods
    ...
end

def application_pods
    ...
    pod 'GoogleMaps'#, :modular_headers => true
    pod 'GooglePlaces', :modular_headers => true
end


def core_application_pods
...
    pod 'GooglePlaces', :modular_headers => true
end


target 'Application' do

  project 'Application/Application.xcodeproj'

  # Pods for Application

  shared_pods
  application_pods

  target 'ApplicationTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'ApplicationUITests' do
    # Pods for testing
  end
end

target 'Core' do

    project 'Core/Core.xcodeproj'

    # Pods for Core

    shared_pods
    core_application_pods

    target 'CoreTests' do
      inherit! :search_paths
      # Pods for testing
    end
end

I even tried putting both pods in shared_pods, enable/disable modular_headers and there is no difference in the outcome.

Here is some of the code which creates the UIGMapsView object. The object is created successfully and Maps delegates are fired before the crash..

final fileprivate func setupMapViewConstraints() {
        if self.mapView == nil {
            let mapView = UIGMapsView(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
            mapView.gmapDelegate = self
            mapView.translatesAutoresizingMaskIntoConstraints = false
            mapView.settings.myLocationButton = false
            self.mapView = mapView
        }

        if let mapView = self.mapView {

            self.view.addSubview(mapView)
                self.view.sendSubviewToBack(mapView)

            let views : [String: UIView] = ["mapView": mapView]
            let vertical = NSLayoutConstraint.constraints(withVisualFormat: "V:|[mapView]|", options: [], metrics: nil, views: views)
            let horizontal = NSLayoutConstraint.constraints(withVisualFormat: "H:|[mapView]|", options: [], metrics: nil, views: views)

            NSLayoutConstraint.activate(vertical + horizontal)

            autoreleasepool {
                mapView.startMonitoringLocation()
                mapView.backToMyPosition()
            }
        }
    }

The screen opens up and about 1 second in that screen the crash appears. (I can even see the blue dot in the middle of the map but the map is all grey...)

I even tried enabling Zombie to try to catch whats is causing this but not much of help there too... here is the screenshot:

Does anyone know what might be causing this crash?

Thanks in advance!
