Problem with POP3

[jmorales20001]

Hello everyone.

I've been using Net library to get emails from an account with POP3. But, since I updated to v1.35 I get this error.

main_process_globals (java line: 307)
java.lang.NoClassDefFoundError: anywheresoftware.b4a.net.POPWrapper

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:625)
at dalvik.system.NativeStart.main(Native Method)

I checked this behaviour on a sample code and always I get the same result:

Sample code:

Sub Activity_Resume
  pop.Initialize("pop.gmail.com", 995, "[email protected]", "passwowrd", "POP")
  pop.UseSSL = True 'Gmail requires SSL.
  pop.Status
  pop.ListMessages    
End Sub
Sub POP_ListCompleted (Success As Boolean, Messages As Map)
  Log("TR_PLC")
  Log("List: " & Success)
  Log("Size: " & Messages.Size)
  If Success Then
      For i = 0 To Messages.Size -1
        Log(Messages.GetKeyAt(i) & "--->" & Messages.GetValueAt(i))
      Next
  Else  
    Log(LastException.Message)
  End If
  pop.Close
End Sub

Can you help me?

Thanks in advance.

Make sure that there is only one copy of Net.jar and Net.xml in both libraries folders.

Thanks for your answer Erel.

I've checked and there is only a copy of Net.jar and Net.xml in libraries folder. Today, I downloaded Net library v1.32 from this thread:

http://www.b4x.com/android/forum/threads/new-net-library-android-ftp-smtp-and-pop3.10892/page-7 (post #127)

With this version POP3 works again but I would like to use smtp with TLS mode (yahoo and hotmail) so I hope you can help me.

Thank you.

Please try v1.37: http://www.b4x.com/android/forum/threads/new-net-library-android-ftp-smtp-and-pop3.10892/#post-60826

I'm afraid I'm still having the same problem with v1.37. I've noticed that the problem occurs even when I only declare a POP3 variable, I mean, when I declare "Dim pop as POP3" the problem occurs.

Make sure again that there isn't any old net.jar (or xml) file in one of the two libraries folder. It seems like this is the problem.

 

[Erel]

Which version of Basic4android are you using?

 

[jmorales20001]

I tried again. Today I downloaded again Net v1.37, I deleted Net.jar and Net.xml from libraries folder and I copied the new version, however, I'm still having the same result. I've attached the result of search "net" in libraries folder.

I'm using Basic4android v2.52.

Sorry, but: "two libraries folder"? I'm just copying the files in:

C:\Program Files (x86)\Anywhere Software\Basic4android\Libraries

What do you mean with the second folder?

Thank you.

You will need to use the older version of Net library. The new version requires B4A 2.7+.
