I'm new to Android Studio and i built an application that reads from the email and extract data from it, it keeps showing that I have an error with the SSL Socket Factory, I've searched a lot and nothing seems to be working, in the manifest I added the permission for internet and tried to change the port number to 143 instead of 993, but it's still the same, if anyone can help me please.
