Java Question Activity referencing

[XverhelstX]

Hello,

In a library I am making, I have to reference to my Main Activity.

/**
    * Starts and initializes sip
    * @param activity - main activity at a project;!!!!!
    */
   public void startSIP(Activity activity) {
      sip.start(activity);
   }

How do I reference to the main activity?

This is giving me an error:

SIP.startSIP(Activity)

Compiling code. 0.05
Generating R file. 0.01
Compiling generated Java code. Error
B4A line: 26
SIP.startSIP(Activity)
javac 1.6.0_21

found : anywheresoftware.b4a.BALayout
required: android.app.Activity
mostCurrent._sip.startSIP((android.app.Activity)(mostCurrent._activity.getObject()));
^
1 error

Any help?

Thanks

Tomas

I don't know what you want to do but can't you just add a BA parameter (which is hidden in the IDE) to provide access to the current activity?

See Erels basic tutorial on writing B4A libraries: http://www.b4x.com/forum/libraries-developers-questions/6810-creating-libraries-basic4android.html

Your Object has to be an Activity Object then.

Well no,
I have to give in my main activity as a parameter for the method:

/**
    * Starts and initializes sip
    * @param activity - main activity at a project;!!!!!
    */
   public void startSIP(Activity activity) {
      sip.start(activity);
   }

Just giving ba in won't work.

When i give in:

/**
    * Starts and initializes sip
    * @param activity - main activity at a project;!!!!!
    */
   public void startSIP() {
      sip.start(ba.activity);
   }

I have the following error:

[Erel]

ba.activity holds the calling activity. It will however be Null if your object is not declared with @ActivityObject.

public void startSIP(BA ba) {
        sip.start(ba.activity);
    }

Thanks Erel.
The other error is related to the sdk.
