Maildroid

Maildroid is a small robust android library for sending emails using SMTP server

Description

Maildroid was born from the frustration of implementing a good emailing solution I had while developing a few client apps. I had to do many hours of unneeded work to make some emailing functions work using old libraries. Those libraries were limited to one SMTP server and because of that frustration, Maildroid was born.

Key Features Sending emails using the SMTP protocol Compatible with all SMTP providers Sending HTML/CSS styled emails The library is using Java Mail API that is well known as the best library for sending emails

Add to your project

Maildroid is hosted on JitPack and it's quite easy to integrate in to your project. Maildroid requires at least Android API level 19 Android KitKat

How do you want to integrate Maildroid into your project

Gradle Add this to your root.gradle file

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

Add dependency

dependencies {
            implementation 'com.github.nedimf:maildroid:v0.0.8-release'
          }

Maven

Add the JitPack repository to your build file

<repositories>
   <repository>
       <id>jitpack.io</id>
       <url>https://jitpack.io</url>
    </repository>
</repositories>

Add the dependency

<dependency>
     <groupId>com.github.nedimf</groupId>
     <artifactId>maildroid</artifactId>
     <version>v0.0.8-release</version>
</dependency>

Add to your app

Adding Maildroid to your app is straight forword process. Library is using Builder pattern to achieve flexebilty and easy to read wholesome implementation:

  MaildroidX.Builder()
            .smtp("")
            .smtpUsername("")
            .smtpPassword("")
            .port("")
            .type(MaildroidXType.HTML)
            .to("")
            .from("")
            .subject("")
            .body("")
            .attachment()
        .isJavascriptDisabled()
        .isisStartTLSEnabled()
        //or
        .attachments() //List<String>
        .onCompleteCallback(object : MaildroidX.onCompleteCallback{
        override val timeout: Long = 3000
        override fun onSuccess() {
            Log.d("MaildroidX",  "SUCCESS")           
        }
        override fun onFail(errorMessage: String) {
             Log.d("MaildroidX",  "FAIL")
        }
         })
         .mail()

DSL implementation:

sendEmail {
      smtp("smtp.mailtrap.io")
      smtpUsername("username")
      smtpPassword("password")
      smtpAuthentication(true)
      port("2525")
      type(MaildroidXType.HTML)
      to("[email protected]")
      from("[email protected]")
      subject("Hello!")
      body("email body")
      attachment("path_to_file/file.txt") 
      //or
      attachments() //List<String>
      callback {
          timeOut(3000)
          onSuccess {
              Log.d("MaildroidX",  "SUCCESS")
          }
          onFail {
              Log.d("MaildroidX",  "FAIL")
          }
      }
 }

Motivation

Maildroid was born from the frustration of implementing a good emailing solution I had while developing a few client apps. I had to do many hours of unneeded work to make some emailing functions work using old libraries. Those libraries were limited to one SMTP server and because of that frustration Maildroid was born..

Showcase

• MacroDroid is using this library (check issue #17 for proof)

FAQ

• How to use Google gmail smtp server

  As stated above every smtp server that uses SSL should be supported.Tutorial how to use smtp.gmail.com:

  • If you choose this SMTP server we suggest making brand new account and enabling less secure apps in settings. Google support link
  • smtp.("smtp.gmail.com")
  • smtpUsername.("") your gmail email adress
  • smtpPassword.("") your gmail password
  • smtpPort.("465") gmail SSL port

• How to test sending emails,but not to affect client

  Maildroid works great with mailtrap.io. They limit 50 message per inbox.Inbox can be erase at any time what it makes it one of the best solution for developers.

• Do this library save any of those data to external parties or servers?

  Maildroid is open source and it DOES NOT save ANY data to extarnal servers or parties.

• Do this library needs AndroidX to run properly?

  Yes,project needs to be compatible with AndroidX QUICK GUIDE

This part will grow more over time as question are posted.
