Xamarin.Forms - Send Email using AWS SES(Simple Email Service)

In this blog post,  you will learn how to send background Email using AWS(Amazon Web Services) SES(Simple Email Service) in Xamarin forms. 

Introduction

Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.

SMTP (Simple Mail Transfer Protocol)

Use SMTP to send and receive mail messages. SMTP provides a set of protocols that simplifies the communication of email messages between email servers. It is an Internet standard for electronic mail (email) transmission. SMTP is a part of the application layer of the TCP/IP protocol. The default TCP port used by SMTP is 25 and the SMTP connections secured by SSL, known as SMTPS, uses the default to port 465. Most SMTP server names are written in the form "smtp.domain.com" or "mail.domain.com": for example, a Gmail account will refer to smtp.gmail.com the Gmail port number is 587.

AWS SES(Simple Email Service)

Amazon Simple Email Service (Amazon SES) is a cloud-based email sending service designed to help digital marketers and application developers send transactional emails. It is an Internet standard for electronic mail (email) transmission. uses the default to port 25, 465 or 587. You can use our SMTP interface or one of the AWS SDKs to integrate Amazon SES directly into your existing applications. SES is available Transport Layer Security (TLS).

Prerequisites

• Visual Studio 2017(Windows or Mac)
• AWS(Amazon Web Services) Account

Setting up a Xamarin.Forms Project

Start by creating a new Xamarin.Forms project.  you’ll learn more by going through the steps yourself.
Choose the Xamarin.Forms App Project type under Cross-platform/App in the New Project dialog.

Name your app, select “Use Shared Library” for shared code, and target both Android and iOS.

You probably want your project and solution to use the same name as your app. Put it in your preferred folder for projects and click Create.

You now have a basic Xamarin.Forms app. Click the play button to try it out.

Create a SES Service in AWS

In this step, create an service in the AWS. Go to the following link. Now, sign in using your preferred account.

https://console.aws.amazon.com/console/home

After sign in, you can create a SES(Simple Email Service) service in AWS console.

Create SMTP Credentials

In this step, you can create a SMTP Credential under SMTP Settings.

Now, you will get the IAM User Name, subsequently click Create.

Now, the SMTP credential created successfully.you can download and use it.

Verify your Email Address

In this step, Verify your Email Address, under Email Addresses menu.

Setting up the User Interface

Go to MainPage.Xaml and write the following code.

MainPage.xaml

Click the play button to try it out.

Troubleshooting

Allow less secure apps

Go to following link you must enable Less secure app access

https://myaccount.google.com/lesssecureapps

You can turn on Less secure app access.

Server Name   : email-smtp.us-east-1.amazonaws.com
Host                  :    email-smtp.us-east-1.amazonaws.com
Port                  : 25, 465 or 587
Use Transport Layer Security (TLS)  : Yes

Send Mail

In this step, write the following code for send email.

MainPage.xaml.cs

Click the play button to try it out.

Xamarin.Forms - Error Log in Visual Studio App Center

In this blog post, you will learn how to collect Error log Using Visual Studio App Center in Xamarin forms. 

Introduction

Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.

Visual Studio App Center

App Center have multiple services, that are most commonly used by mobile developers, where multiple services are acts as a single integrated product. With the use of single integrated product you can build, test, distribute, and monitor your mobile apps, and also implement push notifications.

Support Platforms

1. Android
2. iOS
3. React Native
4. UWP
5. Xamarin
6. macOS
7. Cordova

App Center Services

• Build
• Diagnostics (Formerly Crashes)
• Test
• Analytics
• Distribute
• Push Notifications

Errors

Errors will happens when a runtime exception occurs from an unexpected event, this errors will not terminates the app. These are the errors handled by a try/catch block. When a Error occurs, App Center will records the details of the error, then the state of the app and device are automatically generates a error log based on the records. These logs contains valuable information about the error and it will help you out to fix the error.
