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

• Create an app on the Firebase Console here.

• 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.");

Firebase Crash Reporting 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 initialized 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");
