I'm trying to build an app that sends an email using javamail and gmail's smtp service, but when I run it it crashes when I call Session.getInstance. After debugging it appears that it's a NoClassDefFoundError regarding com.sun.mail.util.MailLogger. I read elsewhere that I had to add an older mail package in order to get it, but I'm still getting errors.
Here's what I have in Android Studio:
// Get system properties Properties properties = System.getProperties(); // Setup mail server properties.put("mail.smtp.host", host); properties.put("mail.smtp.auth", "true"); properties.put("mail.smtp.starttls.enable", "true"); properties.put("mail.transport.protocol","smtp"); properties.put("mail.smtp.port", "587"); authenticator = getAuthenticator(); /* What getAuthenticator looks like: return new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication("myemail@gmail.com ", "password"); } }; */ // Get the default Session object, with authentication try { session = Session.getInstance(properties, authenticator); } catch (Error e) { // Unnecessary code for debugging int hold = 0; } // Create a default MimeMessage object. MimeMessage message = new MimeMessage(session); try { // Set From: header field of the header. message.setFrom(new InternetAddress(from)); // Set To: header field of the header. message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Set Subject: header field message.setSubject(subject); // Now set the actual message message.setText(content); // Send message Transport.send(message); } catch (AddressException e) { throw new Error("bad address"); } catch (MessagingException e){ throw new Error("bad message data"); } And my build looks like this:
apply plugin: 'com.android.application' android { compileSdkVersion 22 buildToolsVersion "22.0.1" defaultConfig { applicationId "com.bsitpa.myfirstapp" minSdkVersion 15 targetSdkVersion 22 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } packagingOptions { exclude 'META-INF/LICENSE.txt' } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.android.support:appcompat-v7:22.2.1' compile 'javax.mail:javax.mail-api:1.5.3' //compile 'javax.mail:mail:1.5.0-b01' compile files('mail-1.5.0-b01.jar') } The debugging error: "java.lang.NoClassDefFoundError: Failed resolution of Lcom/sun/mail/util/MailLogger"
And just so you know, I am completely new to AndroidStudio and Gradle.
Thanks a ton, Ryan
