I am making a email sending application in android phone. For that I included two jar file activation. jar and mail.jar. But when I run this application and try to send the mail, I got following error on LogCat.
java.lang.NoClassDefFoundError: javax.activation.DataHandler
I am new to android. so I am not able to figure out this issue. please Help me. Thanks
There is an Android-friendly port of javamail which you should be using. There are three libraries that you need to include in your app: mail.jar, activation.jar, and additionnal.jar(sic). It looks like you are missing something that the activation library depends on, and this could be because you are not using the Android port of this library.
I have used the Android-friendly version of javamail successfully in a project, and it works really well.
