2. Go to node_modules ➜ react-native-smtp-mailer and add RNSmtpMailer.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNSmtpMailer.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Inside ios folder, if Podfile doesn't exist, create a Podfile with pod init.

``
pod 'mailcore2-ios'
`

##### Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

- Add import com.rnsmtpmailer.RNSmtpMailerPackage; to the imports at the top of the file
- Add new RNSmtpMailerPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:
`
include ':react-native-smtp-mailer'
project(':react-native-smtp-mailer').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-smtp-mailer/android')
`

`


Extra steps

Maybe you need to add (if you encounter error with mimetypes during build), in android/app/build.gradle:

`
android {
...
packagingOptions {
exclude 'META-INF/mimetypes.default'
exclude 'META-INF/mailcap.default'
}
}
`

Usage

`javascript
import RNSmtpMailer from "react-native-smtp-mailer";

RNSmtpMailer.sendMail({
mailhost: "smtp.gmail.com",
port: "465",
ssl: true, // optional. if false, then TLS is enabled. Its true by default in android. In iOS TLS/SSL is determined automatically, and this field doesn't affect anything
username: "usernameEmail",
password: "password",
fromName: "Some Name", // optional
replyTo: "usernameEmail", // optional
recipients: "toEmail1,toEmail2",
bcc: ["bccEmail1", "bccEmail2"], // optional
subject: "subject",
htmlBody: "

",
attachmentPaths: [
RNFS.ExternalDirectoryPath + "/image.jpg",
RNFS.DocumentDirectoryPath + "/test.txt",
RNFS.DocumentDirectoryPath + "/test2.csv",
RNFS.DocumentDirectoryPath + "/pdfFile.pdf",
RNFS.DocumentDirectoryPath + "/zipFile.zip",
RNFS.DocumentDirectoryPath + "/image.png"
], // optional
attachmentNames: [
"image.jpg",
"firstFile.txt",
"secondFile.csv",
"pdfFile.pdf",
"zipExample.zip",
"pngImage.png"
], // required in android, these are renames of original files. in ios filenames will be same as specified in path. In a ios-only application, no need to define it
})
.then(success => console.log(success))
.catch(err => console.log(err));
`

RNFS is from react-native-fs library, used just to demonstrate a way of accessing files in phone filesystem.
