Well, i use the Smtp extention from "vknow360" and on Android 4.4.2 it crashes with the following screen.
Seems thats java.mail doesn't support the old android version. (on android >=9 everything is ok.)
I now moved your contribution into the correct thread
This is your decision
You also could try another of the many email solutions

I am using the SMTP CLIENT extension to send notification emails using my SMTP server, and it works perfectly on the companion app, but when I export it to the apk, it doesn't work; the screen closes when I click “send.”
It works fine on the companion app, but not on the apk.
You can use logcat and try to find out what happens in apk
I’m getting a crash when calling my email-sharing function. The app throws:
java.util.ServiceConfigurationError: javax.mail.Provider: Provider com.sun.mail.imap.IMAPProvider not found
Caused by: ClassNotFoundException: com.sun.mail.imap.IMAPProvider
This happens when javax.mail.Session.getInstance() is created (Jakarta Mail 1.6.7 is logged). It looks like the extension package is missing the IMAP provider classes/resources (e.g., com.sun.mail.imap.IMAPProvider and/or the META-INF/services/javax.mail.Provider entries), so JavaMail fails while loading providers and crashes the app.
Which Android device and Android version are you using for your tests?
Does it work on another device?
Taifun
I tested it on different devices:
Galaxy A56 Android 15
Infinix Note 50 Android 15
Galaxy S24 Android 16
LDPlayer Emulator
Testing using ADB-Tool too
Which of the 2 versions are you using?
Try the version with dependencies
