Java Question Call Automaticly Sub function in B4A

[Hakanunver]

Hello
We have our in SDK auto calling event; how we call automaticly Sub function in our B4A codes..


in java code methods :


@Override

public void onRegisterFailure(String arg0, int arg1) { // TODO Auto-generated method stub Log.w("Fail", "fail"); }



@Override

public void onRegisterSuccess(String arg0, int arg1) { // TODO Auto-generated method stub Log.w("Success", "success"); }


@Override

public void onInviteIncoming(long arg0, String arg1, String arg2, String arg3, String arg4, String arg5, String arg6, boolean arg7, boolean arg8) { // TODO Auto-generated method stub }



@Override

public void onInviteRinging(long arg0, String arg1, int arg2) { // TODO Auto-generated method stub }



@Override

public void onInviteSessionProgress(long arg0, String arg1, String arg2, boolean arg3, boolean arg4, boolean arg5) { // TODO Auto-generated method stub }



@Override

public void onInviteTrying(long arg0) {

// TODO Auto-generated method stub

}

1. Moved to the libraries developers forum.
2. You have created a poll instead of a regular question.
3. You are looking for ba.RaiseEvent.

I cannot understand ba.raiseEvents work type

How can i use it in my wrapper ?

I checked your answer but i didnt see Usage in b4a

Hi ; @Erel
We examine your and other links, But we get errors : " java.lang.NullPointerException"

Our java Code :

package com.sipsdk;
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.DependsOn;
import anywheresoftware.b4a.BA.ShortName;

import com.portsip.OnPortSIPEvent;
import com.portsip.PortSipEnumDefine;
import com.portsip.PortSipSdk;
import android.app.Activity;
import android.content.Context;



@ShortName("PortSip")
@DependsOn(values={"portsipvoipsdk"})
public class initalize extends Activity implements OnPortSIPEvent {
    PortSipSdk  sdk ;
    private BA ba;
    
    int RegFailureCode=0;
    String EventName;
  
    public void initialize(){
  
    }

@Override
    public void onRegisterSuccess(String arg0, int arg1) {
        // TODO Auto-generated method stub  
      
    
        ba.raiseEvent(this, "onregistersuccess_deneme","okk");
        //ba.raiseEventFromDifferentThread(this, null, 0, "onregistersuccess_deneme", false, null);
  
}
}

And Our B4A codes ex:

Sub onregistersuccess_deneme (valor As String)
    
    Log(valor)
End Sub

 

[Erel]

You should always post the full error message from the logs.

ba was never set.

You can set it in the initialize method:

public void initialize(BA ba) {
 this.ba = ba;
}

How I call this initilaze function in java file.. ?

initialize(?????);

public void onRegisterSuccess(String arg0, int arg1) {
        // TODO Auto-generated method stub  
      
        BA.Log("Basardi");  
      
        Initialize_BA(??);
      
        //BA.runAsync(ba, Sender, FullEventName, errorResult, callable);
      
    //    ba.raiseEvent(this, "onregistersuccess_deneme", aaa.toString());
        ba.raiseEvent(this, eventName,"okk");
        //ba.raiseEventFromDifferentThread(this, null, 0, "onregistersuccess_deneme", false, null);
    }

 

[Erel]

You don't call initialize from the java code. It should be called from B4A code.

 

[Hakanunver]

When need use raise function..
Need in B4A set paramater initalize function:

Dim portsip As your_library
portsip.Initialize("your_event_name")

java code sample:

public void Initialize(final BA ba, String EventName) {
   this.ba = ba;
     this.eventName = EventName.toLowerCase(BA.cul);
}

thanks Erel..
