I'm using JavaMail API to send emails from my android app with OAUTH2. App working fine withOut enabling proGuard.

if I set minifyEnabled true in my build.gradle file my app size reduced but failed to send emails from my app. These are the dependencies I used in my app for sending emails.

//Java mail Api for Android
    implementation 'com.sun.mail:android-mail:1.6.2'
    implementation 'com.sun.mail:android-activation:1.6.2'

I had seen some questions in StackOverflow but not working for me. Any suggestions please..

  • @FarukhTariq I'm getting Unresolved class name error while using those proguard rules. Do you have some other solution? – Venkat Aug 04 '21 at 13:05
  • Could you please post the errors you are seeing when using the proposed rules? And could you also mention which version of Android Studio/AGP you are using, and whether you use ProGuard or R8 for shrinking? – sgjesse Aug 05 '21 at 06:28
