android-sendgrid

A simplified Android email library utilising SendGrid's v3 API that targets minSdkVersion 16.

Use with JitPack and implement in your app

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

dependencies {
     implementation 'com.github.jakebreen:android-sendgrid:1.3.1'
}

How to use

Create an instance of the SendGrid library tied to your API key.

SendGrid sendGrid = SendGrid.create(@NonNull String apiKey)

Create a SendGridMail and provide the required attributes.

SendGridMail mail = new SendGridMail()
mail.addRecipient(@NonNull String email, @Nullable String name)
mail.setFrom(@NonNull String email, @Nullable String name)
mail.setSubject(@NonNull String subject)
mail.setContent(@NonNull String body)

Set a plain text or a html text content body, when using a template neither of these content variables need to be set.

mail.setContent(@NonNull String body)
mail.setHtmlContent(@NonNull String body)

Send a mail with the library's SendTask.

SendTask task = new SendTask(sendGrid);
SendGridResponse response = task.send(mail);

Send a mail with RxJava.

Single.fromCallable(sendGrid.send(mail))
    .subscribeOn(Schedulers.io())
    .subscribe(response -> {
            if (response.isSuccessful()) {
                // ...
            }
        }
    );

Send requests return a SendGridResponse that contains the success state of the request and the associated HTTP response code. A failed request will contain the error message from the API.

response.isSuccessful()
response.getCode()
response.getErrorMessage()

Additional SendGridMail methods that aren't required to send an email include templates, tracking, carbon copies, attachments and others

mail.addAttachment(@NonNull File file)
mail.addAttachment(@NonNull Uri uri)
mail.addRecipientCarbonCopy(@NonNull String email, @Nullable String name)
mail.addRecipientBlindCarbonCopy(@NonNull String email, @Nullable String name)
mail.setReplyTo(@NonNull String email, @Nullable String name)
mail.setSendAt(@NonNull int sendAt)
mail.setClickTrackingEnabled(@NonNull Boolean enabled)
mail.setOpenTrackingEnabled(@NonNull Boolean enabled)
mail.setSubscriptionTrackingEnabled(@NonNull Boolean enabled)
mail.setUnsubscribeGroupId(@NonNull int groupId)
mail.setUnsubscribeGroupIds(@NonNull int groupId, List<Integer> groupIds)

Transactional email templates and custom data can be applied to the SendGridMail in the form of a JSONObject structured into key/value pairs

mail.setTemplateId(@NonNull String templateId)
mail.setDynamicTemplateData(@NonNull JSONObject jsonObject)

// JSONObject structured into key/value pairs
final JSONObject templateData = new JSONObject();
templateData.put("forename", "Jane");
templateData.put("surname", "Doe");
templateData.put("message", "Hello, This is my email");

mail.setDynamicTemplateData(templateData)

TestApp

A test app included when cloning the library to test the library with file attachments, uses RxJava2. Feel free utilise this app.
