crash

问题 I'm developing an app which in a case of crash, needs to save some data with the time of the crash. Now, I'm saving the data in onDestroy() like this: @Override protected void onDestroy() { saveState(); super.onDestroy(); } But whenever I crash my app on purpose, onDestroy() is not called and my data is not saved. My question is, how can I save my data on a crash? Which approach should I take? Because I need the time of the crash to be also saved, it's mandatory. 回答1: The

问题 I am aware that according to the changelog (0.12.9+5). It supposedly fixed a crash on android where Transaction s attempted while offline would result in an app crash. However, even with 0.13.7 (the version I'm using). I'm still running into app crashes. There is no error log in the console (just immediate crash). I've tried: Running my app in debug mode on a physical device (same behavior) Attaching error handle callback (not called) Lowering my cloud_firestore version down to 0.12.11 (the

问题 I am currently learning C in one of my courses at the university. Now we have a task to solve and I am not sure how to do it. The task looks like this: "Is it possible to let this program crash with user inputs? If so, explain this case." The program we have been given is quite simple and looks like this: #include <stdio.h> // Include to use printf, scanf int main() { // Define buffers to store user name and password char username[16]; char password[16]; // Read username and password from

问题 I am not an engineer, so a bit overwhelmed with this crash in my simple weather app that shows Celsius and Fahrenheit side by side. I only updated to iOS 13 SDK and changed some colors for night mode. App runs fine in simulator and also launches fine on device when started out of Xcode. However, when hard closing app and re-launching on device I get the following crash. I have no idea how to debug crashes, so I'd appreciate any help!

问题 I'm having a problem with a tester that my application crashes in initialization. I added more logging and exception handling but it still crashes with the generic "this program has stopped working" message rather than triggering my error handling. Given my main() looks like this and has catch(...) under what circumstances would this not be triggered? try{ simed::CArmApp app(0, cmd); for(bool done = false;!done;) { done = !app.frame(); } } catch(const std::runtime_error &e){

问题 I'm using a "RectGetter" to get the CGRect of a View . Like this: Text("Hello") .background(RectGetter(rect: self.$rect)) struct RectGetter: View { @Binding var rect: CGRect var body: some View { GeometryReader { proxy in self.createView(proxy: proxy) } } func createView(proxy: GeometryProxy) -> some View { DispatchQueue.main.async { self.rect = proxy.frame(in: .global) // crash here } return Rectangle().fill(Color.clear) } } But sometimes I get a crash when setting the rect.
