Install

``bash
npm install capacitor-email-composer
npx cap sync
`

Attachments

You can add attachments to the draft mail by using the attachments option in the open(...) method.
Every attachment needs a type and a path. If you are adding a base64 type attachment, you also need to set the name:

$3

The path to the files must be defined absolute from the root of the file system. On Android the user has to allow the app first to read from external storage!

`ts
import { EmailComposer } from 'capacitor-email-composer'

EmailComposer.open({
attachments: [{
type: 'absolute',
path: 'storage/sdcard/icon.png' // Android
}]
})
`

$3

Each app has a resource folder, e.g. the res folder for Android apps or the Resource folder for iOS apps. The following example shows how to attach the app icon from within the app's resource folder.

`ts
import { EmailComposer } from 'capacitor-email-composer'

EmailComposer.open({
attachments: [{
type: 'resource',
path: 'icon.png'
}]
})
`

$3

The path to the files must be defined relative from the root of the mobile web app assets folder, which is located under the build folder.

`ts
import { EmailComposer } from 'capacitor-email-composer'

EmailComposer.open({
attachments: [{
type: 'asset',
path: '/icon/favicon.png' // starting slash is important
}]
})
`

$3

The code below shows how to attach a base64 encoded image which will be added as an image. You must set a name.

⚠️ Note: large base64 content can crash the app, if you need to pass large files (>1000Kb) use a uri intead.

`ts
import { EmailComposer } from 'capacitor-email-composer'

EmailComposer.open({
attachments: [{
type: 'base64',
path: 'iVBORw0KGgoAAAANSUhEUgAAADwAAAA8CAYAAAA6...',
name: 'icon.png' // this is required
}]
})
`

Troubleshooting

$3

When sharing data between two applications, the Android OS might throw this exception for several reasons, for example if the file is too large.
