A React Native library for Fabric, Crashlytics and Answers

For Twitter Kit support, see react-native-fabric-twitterkit

• First, set up Fabric / Crashlytics in your app as instructed on Fabric.io. This includes downloading the fabric app and walking through the setup steps (downloading the SDK, adding it to your project and making some changes to your project).

rnpm install react-native-fabric

rnpm will automatically link all the necessary libraries for both iOS and Android.

If the rnpm installation goes off without a hitch, you can now skip to the Crashlytics Usage section or the Answers Usage section.

npm install react-native-fabric --save

• Alternatively for Android, if you don't use Android studio you can skip the first step and instead follow the steps described in Android as well as the steps in Android without Android Studio.

• add the following line to Podfile

pod 'ReactNativeFabric', :path => '../node_modules/react-native-fabric'

• Open your project in Xcode
• Run open node_modules/react-native-fabric/ios
• Drag SMXCrashlytics.xcodeproj into your Libraries group
• Select your main project in the navigator to bring up settings
• Under Build Phases expand the Link Binary With Libraries header
• Scroll down and click the + to add a library
• Find and add libSMXCrashlytics.a under the Workspace group
• ⌘+B

*Note: Android support requires React Native 0.16 or later

• Edit android/settings.gradle to look like this (without the +):

  rootProject.name = 'MyApp'
  
  include ':app'
  
  + include ':react-native-fabric'
  + project(':react-native-fabric').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fabric/android')

• Edit android/app/build.gradle (note: app folder) to look like this:

  apply plugin: 'com.android.application'
  
  android {
    ...
  }
  
  dependencies {    
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.facebook.react:react-native:0.19.+'
  + compile project(':react-native-fabric')
  }

• RN < 0.29 - Edit your MainActivity.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  package com.myapp;
  
  + import com.smixx.fabric.FabricPackage;
  
  ....
  public class MainActivity extends ReactActivity {
    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
  +         new FabricPackage(),
            new MainReactPackage()
        );
    }
  }

• RN 0.29+ - Edit your MainApplication.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  package com.myapp;
  
  + import com.smixx.fabric.FabricPackage;
  
  ....
  public class MainApplication extends Application implements ReactApplication {
    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
  +         new FabricPackage(),
            new MainReactPackage()
        );
    }
  }

Make sure you also follow the steps described in Android.

• Edit your build.gradle (note: app folder) to look like this:

  apply plugin: "com.android.application"
  
  + buildscript {
  +   repositories {
  +     maven { url 'https://maven.fabric.io/public' }
  +   }
  +   dependencies {
  +     // The Fabric Gradle plugin uses an open ended version to react
  +     // quickly to Android tooling updates
  +     classpath 'io.fabric.tools:gradle:1.+'
  +   }
  + }
  + apply plugin: 'io.fabric'
  + repositories {
  +   maven { url 'https://maven.fabric.io/public' }
  + }
  
  [...]
  
  dependencies {
      [...]
  +     compile('com.crashlytics.sdk.android:crashlytics:2.5.5@aar') {
  +         transitive = true;
  +     }
  }

• RN < 0.29 - Edit your MainActivity.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  + import android.os.Bundle;
  + import com.crashlytics.android.Crashlytics;
  + import io.fabric.sdk.android.Fabric;
  
  public class MainActivity extends ReactActivity {
  
  +   @Override
  +   protected void onCreate(Bundle savedInstanceState) {
  +       super.onCreate(savedInstanceState);
  +       Fabric.with(this, new Crashlytics());
  +   }
  
    [...]
  
  }

• RN 0.29+ - Edit your MainApplication.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  + import com.crashlytics.android.Crashlytics;
  + import io.fabric.sdk.android.Fabric;
  
  public class MainApplication extends Application implements ReactApplication {
  
  +   @Override
  +   public void onCreate() {
  +       super.onCreate();
  +       Fabric.with(this, new Crashlytics());
  +   }
  
    [...]
  
  }

• Note: the onCreate access privilege goes from protected to public from RN 0.28+

• Edit your AndroidManifest.xml (in android/app/src/main/) to look like this. Make sure to enter your fabric API key after android:value=, you can find your key on your fabric organisation page.

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      [...]
      <application
        [...]
  +       <meta-data
  +         android:name="io.fabric.ApiKey"
  +         android:value=[YOUR API KEY]
  +       />
      </application>
  +   <uses-permission android:name="android.permission.INTERNET" />
  </manifest>

• Note: logging will not be registered on Android to the Fabric dashboard until the app is bundled for release.

To see all available methods take a look at Crashlytics.js

var Fabric = require('react-native-fabric');

var { Crashlytics } = Fabric;

Crashlytics.setUserName('megaman');

Crashlytics.setUserEmail('[email protected]');

Crashlytics.setUserIdentifier('1234');

Crashlytics.setBool('has_posted', true);

Crashlytics.setString('organization', 'Acme. Corp');

// Forces a native crash for testing
Crashlytics.crash();

// Due to differences in primitive types between iOS and Android I've exposed a setNumber function vs. setInt, setFloat, setDouble, setLong, etc                                        
Crashlytics.setNumber('post_count', 5);

// Record a non-fatal JS error only on Android
Crashlytics.logException('');

// Record a non-fatal JS error only on iOS
Crashlytics.recordError('something went wrong!');

To see all available function take a look at Answers.js

var Fabric = require('react-native-fabric');

var { Answers } = Fabric;

// All log functions take an optional array of custom attributes as the last parameter
Answers.logCustom('Performed a custom event', { bigData: true });

Answers.logContentView('To-Do Edit', 'To-Do', 'to-do-42', { user-id: 93 });

Answers.logAddToCart(24.50, 'USD', 'Air Jordans', 'shoes', '987654', {color: 'red'});

Answers.logInvite('Facebook');

Answers.logLogin('Twitter', true);

Answers.logSearch('React Native');

Answers.logShare('Twitter', 'Big news article', 'post', '1234');

Answers.logSignUp('Twitter', true);

Answers.logPurchase(24.99,'USD',true, 'Air Jordans', 'shoes', '987654');
