The URL of my app can be something like www.example.com/#/c/2/v/1
Yet the slashes and numbers after # are causing my GatsbyJS generated pages to crash.
The error message is: Uncaught DOMException: Failed to execute 'querySelector' on 'Document': '#/c/2/v/1' is not a valid selector.
The parameters after hash are not to scroll, put to provide parameters to the app.
I've been struggling with this for two days.Please Help.
I hope someone is able to help me out here. For a weeks I am seeing this exception in my app:

Because _UIButtonBarStackView is mentioned I assume that it has something to do with a UINavigationBarUIBarButtons. It seems to happen when I dismiss a modally presented UINavigationController, but I am not sure.It also looks like it started to happen with iOS 13.4.1, because I can't find any crash report with any older version.
Anyone might know what's going on here?
I developed my R code on my local computer. In my code, I mainly use swmmr package to run SWMM (stormwater management model) and further analysis related to the model outputs. To do that, I have used multiple packages (dplyr, shiny, leaflet, xts, zoo, ...). Everything is fine when I use my local computer and I can run my code from first to last and it works properly.
Now, I decided to move all my codes to AWS (amazon web services) EC2 cloud. Because I need to run my code every one hour. I had some difficulties with this transformation, but I could solve most of them.However, somewhere in my code, when I use the read_out() function from swmmr package, I get some warnings about masking some functions from other packages (attached figure), and my studio in AWS server crash.
Any idea about how I can fix this problem is appreciated. Why does Rstudio in AWS crash when I use this function? I really need to fix this problem ASAP.
You can see the warnings here:
I don't have access to server and work with a laptop with Intel Core i3-2350M processor, 2.30GHz CPU, 8 gigabyte RAM. I need to process large bioinformatics datasets using R. How can I do it or what I need to purchase to stop system crash? I can't buy a faster laptop.
Any idea is much appreciated.
SOLVED
Rewrote pickImageFromGallery as below. Don't know why it works though.
Intent galleryIntent = new Intent(); galleryIntent.setType("image*/"); galleryIntent.setAction(Intent.ACTION_PICK); startActivityForResult(Intent.createChooser(galleryIntent, "Select picture"), IMAGE_GALLERY_CODE); }I'm currently making an app and want to open the gallery to pick out an image (I've also written code for taking a photo but that part works just fine). After giving permission to do so the app will crash and i can't figure out why. I've tried using different verions of android and phone types as emulator but with no different outcome. I've read in a few places that it could be due to some nullpointer when attempting to get.Data(), but since i'm checking for it i can't see why that would be a problem here. Any suggestion on what could be causing this would be very appreciated :) (I get no error message when it crashes)

It first happened when I update Flutter version to 1.10.x I could not remember which version did I use, properly. It should be 1.7.8, it was stable. To fix it I downgrade the flutter to 1.7.8+4 and also downgrade firebase related pub packages. But error still here.

So I've been trying to create a discriminated union for my project. Coming from C, I thought it would be trivial... ;)
The structure is named Message. It has a MessageType and an inner union which holds either a MessageGet or a MessageSet.
enum MessageType { MESSAGE_GET, MESSAGE_SET};struct MessageGet { std::string store_name; std::vector<uint8_t> key;};struct MessageSet { std::string store_name; std::vector<uint8_t> key; std::vector<uint8_t> value;};struct Message { MessageType type; uint64_t sender_id; union U { U() : get() {} U(const U& other) { get = other.get; set = other.set; } ~U() {} U& operator=(const U& other) { set = other.set; get = other.get; return *this; } MessageGet get; MessageSet set; } as; Message() {} ~Message() { switch (type) { case MESSAGE_GET: { as.get.~MessageGet(); break; } case MESSAGE_SET: { as.set.~MessageSet(); break; } } } Message(MessageGet get, uint64_t sender_id) { type = MESSAGE_GET; as.get = get; sender_id = sender_id; } Message(MessageSet set, uint64_t sender_id) { type = MESSAGE_SET; as.set = set; sender_id = sender_id; } Message(const Message& other) { type = other.type; as = other.as; sender_id = other.sender_id; } Message& operator=(const Message& other) { type = other.type; as = other.as; sender_id = other.sender_id; return *this; }};The program crashes elsewhere in the code where I do something like this:
Message message(MessageGet {std::move(store_name), std::move(key)}, sender);messages.push_back(message); // messages is a local std::vector<Message>It doesn't crash with an exception - simply a crash.
I've managed to narrow it down to inside the Message copy constructor. After that, have no clue what causes this. Ideas would be appreciated.
when i gave my friends to test my app, one of them experienced crash on start up. I don't find any issues in code part of my project but i don't get it why few devices crash. I have my whole project on git hub https://github.com/hsr121/agile.git .
I tried compressing background jpeg image from 9.5 MB to 2 MB. Cannot figure out the problem, the amazon app store rejects to upload my app dues to same crashing reason.
I have been developing a Xamarin Forms app for 9 months now, however lately I've discovered a problem. It successfully deploys my application to the device, and I can use it normally, but after closing it and try to open it again it keeps crashing.
I have tried in other devices and have the same problem, also I cannot debug where the problem is because it only happens if I try to open the app when it has been previously closed so the debugger is no longer running.
As I said before, I just have had this problem recently, it was working perfectly fine.

After checking for memory leaks, I run this app on my Amazon Fire Stick for an extended period of time, but regardless after around 8-9 hours it crashes without exception on the console. How did I check for memory leaks:
LeakCanary did not detect any leaks.Watching the memory profiler over time I see that the total memory used always consistently averages 400MB, even at the 8 hour mark.Comparing to the old version of the program which was worse (it had a lot of unrelated code and was an older project), LeakCanary DID detect leaks on the exact same code, and the profiler did slowly increase the total memory used. This led me to believe that isolating all the necessary code and moving it to a new project solved part of the problem.Now, the really weird thing is that even though the ALLOCATED memory in the profiler fluctuates, it's DECREASING. In fact to negative numbers. By the 8 hour mark I was seeing it average around -40000. Why's the allocated number negative?
Finally, here's a recurring and suspicious console log I saw right before the crash, hinting it is indeed a memory related crash
I/Kernel: [126985.795618].(0)[3041:RenderThread]lowmemorykiller: Killing 'VMetricsProcess' (29681), adj 1, score_adj 58, [126985.795618] to free 20124kB on behalf of 'RenderThread' (3041) because [126985.795618] cache 40244kB is below limit 40960kB for oom_score_adj 58 [126985.795618] Free memory is 0kB above reservedAny help would be greatly appreciated as I've been struggling with this bug for so long.

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'm new to Django.Since in a development environment it happens that an error occurs after a request (often because it is badly handled) and Django crashes, I thought about creating a script (in production) to detect if Django is running and if not run it again (something like this). And of course after adding block try except everywhere.
But since Django is well done it wouldn't surprise me if this concern is already taken in consideration, hence my question.
Thank you.
it is a very simple QT+CEF windows application, see https://github.com/GreatTux/CefMinGWQt
when I close the main window CEF trigger the breakpoint:I guess I failed here:

OK, so since I last successfully built, all I have done is tried adding Google Play Services to my game, from here.
I imported the unity package, and setup the google play games for android in the relevant setup window.
I tried building at this point, however I was unable to, recieved that strange error whilst building dex files signifying there being a conflict between aar files. I narrowed it down to being caused by both assets/plugins/android/play-services-base-9.0.2 and assets/plugins/android/play-services-basement-9.0.2.
I unchecked both of these being built to android to have the conversion to dex error stuff go away. I assumed this would be OK.
I then pushed the app onto Google Play, (alpha environment) along with a small controller script for Google Play to login on start():
void Awake(){ // recommended for debugging: PlayGamesPlatform.DebugLogEnabled = true; // Activate the Google Play Games platform PlayGamesPlatform.Activate();}void Start(){ Login();}void Login(){ Social.localUser.Authenticate((bool success) => { LoggedIn = success; });}However Unity appears to be crashing before opening the first scene. It is crashing right away, upon startup. The logcat stuff can be seen here.
The problem appears to occur around line 842:

::Additional Info::
So I have rolled back to a point where I have the unity package imported into Unity, but I haven't configured it yet, giving it my xml containing the resources. It is giving a nullreferenceexception in the editor at this point:
NullReferenceException: Object reference not set to an instance of an objectGooglePlayServices.PlayServicesResolver.OnPostprocessAllAssets (System.String[] importedAssets, System.String[] deletedAssets, System.String[] movedAssets, System.String[] movedFromAssetPaths) (at Assets/PlayServicesResolver/Editor/PlayServicesResolver.cs:104)System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:222)Rethrow as TargetInvocationException: Exception has been thrown by the target of an invocation.System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:232)System.Reflection.MethodBase.Invoke (System.Object obj, System.Object[] parameters) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MethodBase.cs:115)UnityEditor.AssetPostprocessingInternal.PostprocessAllAssets (System.String[] importedAssets, System.String[] addedAssets, System.String[] deletedAssets, System.String[] movedAssets, System.String[] movedFromPathAssets) (at C:/buildslave/unity/build/Editor/Mono/AssetPostprocessor.cs:27)UnityEditor.AssetDatabase:Refresh()GooglePlayGames.Editor.GPGSUpgrader:.cctor() (at Assets/GooglePlayGames/Editor/GPGSUpgrader.cs:107)UnityEditor.EditorAssemblies:SetLoadedEditorAssemblies(Assembly[])The line it references is:

Now, I can build this APK and run it on my phone fine, no problems. (Obviously google play game services won't do much, as it isn't configured).
So, I go to Window >> Google Play Games >> Setup >> Androidand here, I paste my resources XML.I give a place and name for the resources C# file, and hit Setup.
I see the following Jar Dependency Conflict options:

I just tried again, this time pressing OK to all of them, and attempted to build again having only done this since my last successful build. Whilst converting the jars to dex format, it fails the build giving the following error:
