Forzare un arresto anomalo per testare l'implementazione
Trova un GameObject esistente, quindi aggiungi il seguente script. Questo
script causerà un arresto anomalo del test pochi secondi dopo l'esecuzione dell'app.
usingSystem;usingUnityEngine;publicclassCrashlyticsTester:MonoBehaviour{intupdatesBeforeException;// Use this for initializationvoidStart(){updatesBeforeException=0;}// Update is called once per framevoidUpdate(){// Call the exception-throwing method here so that it's run// every frame updatethrowExceptionEvery60Updates();}// A method that tests your Crashlytics implementation by throwing an// exception every 60 frame updates.

Crea la tua app e carica le informazioni sui simboli al termine della build.
iOS+: il plug-in Firebase Unity Editor configura automaticamente il progetto Xcode per caricare il file di simboli.
Android: per le tue app per Android che utilizzano IL2CPP, esegui il comando
Firebase CLI crashlytics:symbols:upload per caricare il file
dei simboli.
Esegui l'app. Una volta in esecuzione, osserva il log del dispositivo e attendi
che l'eccezione venga attivata da CrashlyticsTester.
iOS+: visualizza i log nel riquadro inferiore di Xcode.
Android: visualizza i log eseguendo il seguente comando nel terminale:
adb logcat.
Vai alla dashboard Crashlytics della
console Firebase per visualizzare l'arresto anomalo del test.
Se hai aggiornato la console e dopo cinque minuti ancora non vedi l'arresto anomalo del test, prova ad attivare la registrazione di debug (sezione successiva).
Attiva logging di debug per Crashlytics
Se non vedi l'arresto anomalo del test nella dashboard Crashlytics, puoi
utilizzare la registrazione di debug per Crashlytics per aiutarti a individuare il problema.
Attiva la registrazione di debug per Firebase aggiungendo il seguente codice all'inizializzazione dell'app:
Forzare un arresto anomalo di test. La prima sezione di questa pagina descrive come farlo.
Se dopo cinque minuti non vedi i log di Firebase o l'arresto anomalo del test nella dashboard
della console Firebase, contatta
l'assistenza Firebase con una copia
dell'output dei log per ricevere ulteriore assistenza per la risoluzione dei problemi.Crashlytics

Add code to your app that you can use to force a test crash.\n\n You can use the following code to add a button to your app that, when\n pressed, causes a crash. The button is labeled \"Test Crash\".\n\n \u003cbr /\u003e\n\n SwiftUI \n\n ```swift\n Button(\"Crash\") {\n fatalError(\"Crash was triggered\")\n }\n ```\n\n UIKit \n\n Swift \n\n ```python\n import UIKit\n\n class ViewController: UIViewController {\n override func viewDidLoad() {\n super.viewDidLoad()\n\n // Do any additional setup after loading the view, typically from a nib.\n\n let button = UIButton(type: .roundedRect)\n button.frame = CGRect(x: 20, y: 50, width: 100, height: 30)\n button.setTitle(\"Test Crash\", for: [])\n button.addTarget(self, action: #selector(self.crashButtonTapped(_:)), for: .touchUpInside)\n view.addSubview(button)\n }\n\n @IBAction func crashButtonTapped(_ sender: AnyObject) {\n let numbers = [0]\n let _ = numbers[1]\n }\n }\n ```\n\n Objective-C \n\n ```objective-c\n #import \"ViewController.h\"\n\n @implementation ViewController\n ‐ (void)viewDidLoad {\n [super viewDidLoad];\n\n // Do any additional setup after loading the view, typically from a nib.\n\n UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect];\n button.frame = CGRectMake(20, 50, 100, 30);\n [button setTitle:@\"Test Crash\" forState:UIControlStateNormal];\n [button addTarget:self action:@selector(crashButtonTapped:)\n forControlEvents:UIControlEventTouchUpInside];\n [self.view addSubview:button];\n }\n\n ‐ (IBAction)crashButtonTapped:(id)sender {\n @[][1];\n }\n\n @end\n ```\n2. Build and run your app in Xcode with the Xcode debugger disconnected.\n\n | **The Xcode debugger prevents crash reports\n | from being sent to Crashlytics.** Complete the following steps to disconnect your test device or simulator from the Xcode debugger ***before*** forcing a crash.\n 1. Click play_arrow**Build and then\n run the current scheme** to build your app on a test device or\n simulator.\n\n 2. Wait until your app is running, then click\n stop**Stop running the scheme or\n action** to close the initial instance of your app. This initial\n instance included the debugger that interferes with Crashlytics.\n\n3. Force the test crash in order to send your app's first crash report:\n\n 1. Open your app from the home screen of your test device or simulator.\n\n 2. In your app, press the \"Test Crash\" button that you added using the code\n above.\n\n 3. After your app crashes, run it again from Xcode so that your app can\n send the crash report to Firebase.\n\n4. Go to the [Crashlytics dashboard](https://console.firebase.google.com/project/_/crashlytics) of the\n Firebase console to see your test crash.\n\nIf you've refreshed the console and you're still not seeing the test crash\nafter five minutes, try enabling debug logging (next section).\n\nEnable debug logging for Crashlytics\n\nIf you don't see your test crash in the Crashlytics dashboard, you can\nuse debug logging for Crashlytics to help track down the problem.\n\n1. Enable debug logging:\n\n 1. In Xcode, select **Product \\\u003e Scheme \\\u003e Edit scheme**.\n\n 2. Select **Run** from the left menu, then select the **Arguments** tab.\n\n 3. In the *Arguments Passed on Launch* section, add `-FIRDebugEnabled`.\n\n2. Force a test crash. The first section on this page describes how to do this.\n\n3. Within your logs, search for a log message from Crashlytics that\n contains the following string, which verifies that your app is sending\n crashes to Firebase.\n\n ```\n Completed report submission\n ```\n | After confirming that your app is sending crashes, you can optionally disable debug logging by removing the `-FIRDebugEnabled` from the arguments passed on launch.\n\nIf you don't see this log or your test crash in the Crashlytics dashboard\nof the Firebase console after five minutes, reach out to\n[Firebase Support](/support/troubleshooter/crashlytics/missing) with a copy of\nyour log output so that we can help you troubleshoot further.\n\nNext steps\n\n- [Customize your crash report setup](/docs/crashlytics/customize-crash-reports) by adding opt-in reporting, logs, keys, and tracking of non-fatal errors."]]
