# Firebase Crash Reporting

# How to report an error

Firebase Crash Reporting (opens new window) automatically generates reports for fatal errors (or uncaught exceptions).

You can create your custom report using:

FirebaseCrash.report(new Exception("My first Android non-fatal error"));

You can check in the log when FirebaseCrash initialized the module:

07–20 08:57:24.442 D/FirebaseCrashApiImpl: **FirebaseCrash reporting API initialized** 07–20 08:57:24.442 I/FirebaseCrash: **FirebaseCrash reporting initialize**d com.google.firebase.crash.internal.zzg@3333d325 07–20 08:57:24.442 D/FirebaseApp: **Initialized class com.google.firebase.crash.FirebaseCrash.**

And then when it sent the exception:

07–20 08:57:47.052 D/FirebaseCrashApiImpl: **throwable java.lang.Exception: My first Android non-fatal error** 07–20 08:58:18.822 D/FirebaseCrashSenderServiceImpl: **Response code: 200** 07–20 08:58:18.822 D/FirebaseCrashSenderServiceImpl: **Report sent**

You can add custom logs to your report with

FirebaseCrash.log("Activity created");

# How to add Firebase Crash Reporting to your app

In order to add Firebase Crash Reporting to your app, perform the following steps:

  • Create an app on the **Firebase Console** [here](https://console.firebase.google.com/).
  • Copy the `google-services.json` file from your project into your in `app/` directory.
  • Add the following rules to your root-level **build.gradle** file in order to include the `google-services` plugin: 
    buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}
  • In your module Gradle file, add the `apply plugin` line at the bottom of the file to enable the Gradle plugin: 
    apply plugin: 'com.google.gms.google-services'
  • Add the dependency for **Crash Reporting** to your app-level **build.gradle** file: 
    compile 'com.google.firebase:firebase-crash:10.2.1'
  • You can then fire a custom exception from your application by using the following line: 
    FirebaseCrash.report(new Exception("Non Fatal Error logging"));

    All your fatal exceptions will be reported to your Firebase Console.

  • If you want to add custom logs to a console, you can use the following code:

    FirebaseCrash.log("Level 2 completed.");
