Hello We Try Create B4A library for portsip sdk. This sdk link :
http://www.portsip.com/sites/downloads/sdk/AndroidSample_Eclipse.zip

We try eclipse and SLC , we get similar errors.

Where our mistake dont understand.. This Library very importand for as.

our simple test code:

B4X: 
#Region  Project Attributes 
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName: 
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes 
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim portsip As PortSip

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    portsip.Initialize_Sip("333","zkr333","192.168.1.233",5222)
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

And our Java code :
B4X: 
package com.portsiplib;

import com.portsip.PortSipSdk;
import android.content.Context;
import anywheresoftware.b4a.BA.ShortName;
@ShortName("PortSip")
public class PortSip {
        static{
            System.loadLibrary("portsip_core");
            System.loadLibrary("portsip_media");
        }
    public String Initialize_Sip(String username,String password,String server,int port){
   
        PortSipSdk sdk = new PortSipSdk();
   
        return "RUN";
    }

}

Our Errors :

you need to add an dependson for the jar you are refering to (which you use inside you pojects libs folder...

B4X: 
@DependsOn(values={"portsipfilename"})
if it is portsipfilename.jar
