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

Programming language: Kotlin

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("")
            .smtpAuthentication()
            .port("")
            .type(MaildroidXType.HTML)
            .to("")
            .from("")
            .subject("")
            .body("")
            .attachment("")
        //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("johndoe@email.com")
      from("janedoen@email.com")
      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")
          }
      }
