Manual Installation: Android

• In android/setting.gradle

...
include ':RNMail', ':app'
project(':RNMail').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-mail/android')

• In android/app/build.gradle

...
dependencies {
    ...
    compile project(':RNMail')
}

• if MainActivity extends Activity: register module in MainActivity.java

import com.chirag.RNMail.*;  // <--- import

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {
  ......

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mReactRootView = new ReactRootView(this);

    mReactInstanceManager = ReactInstanceManager.builder()
      .setApplication(getApplication())
      .setBundleAssetName("index.android.bundle")
      .setJSMainModuleName("index.android")
      .addPackage(new MainReactPackage())
      .addPackage(new RNMail())              // <------ add here
      .setUseDeveloperSupport(BuildConfig.DEBUG)
      .setInitialLifecycleState(LifecycleState.RESUMED)
      .build();

    mReactRootView.startReactApplication(mReactInstanceManager, "ExampleRN", null);

    setContentView(mReactRootView);
  }

  ......

}

• else if MainActivity extends ReactActivity: register module in MainApplication.java

import com.chirag.RNMail.*; // <--- import

public class MainApplication extends Application implements ReactApplication {
    ....

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new RNMail()      // <------ add here
      );
    }
  };

File Attachments on Android

Addition setup is required for Android file sharing, see https://developer.android.com/training/secure-file-sharing/setup-sharing

It is expected that the android:authorities property is set to the app's package name with ".fileprovider" appended to the end.

Manual Installation: iOS

1. Run npm install react-native-mail --save
2. Open your project in XCode, right click on Libraries and click Add Files to "Your Project Name" (Screenshot) then navigate to node_modules/react-native-mail and select RNMail.xcodeproj (Screenshot).
3. Add libRNMail.a to Build Phases -> Link Binary With Libraries (Screenshot).
4. Whenever you want to use it within React code now you can: var Mailer = require('NativeModules').RNMail;

Example

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import { View, Alert, Button } from 'react-native';
import Mailer from 'react-native-mail';

export default class App extends Component {

  handleEmail = () => {
    Mailer.mail({
      subject: 'need help',
      recipients: ['support@example.com'],
      ccRecipients: ['supportCC@example.com'],
      bccRecipients: ['supportBCC@example.com'],
      body: '<b>A Bold Body</b>',
      isHTML: true,
      attachment: {
        path: '',  // The absolute path of the file from which to read data.
        type: '',   // Mime Type: jpg, png, doc, ppt, html, pdf, csv
        name: '',   // Optional: Custom filename for attachment
      }
    }, (error, event) => {
      Alert.alert(
        error,
        event,
        [
          {text: 'Ok', onPress: () => console.log('OK: Email Error Response')},
          {text: 'Cancel', onPress: () => console.log('CANCEL: Email Error Response')}
        ],
        { cancelable: true }
      )
    });
  }

  render() {
    return (
      <View style={styles.container}>
        <Button
          onPress={this.handleEmail}
          title="Email Me"
          color="#841584"
          accessabilityLabel="Purple Email Me Button"
        />
      </View>
    );
  }
}

Note

On Android, the callback will only be called if an error occurs. The event argument will contain a string with the exception or error message.

Here is how it looks:
